How to understand beliefs
Authors: Gopnik Alison
Published: February 2010

In this response various possible objections to the critique of first-person-authority in Gopnik (1993), are considered. The heart of all three objections is that “beliefs” and other notions of commonsense psychology should not be construed as attempts to describe the functional character of our minds. Rather, they are 1) an evolutionarily determined technique for dealing with our conspecifics (Bogdan) or 2) the result of interpretation (Van Brakel) or 3) self-constitutive entities which exist only when we have the concept of their existence (Greve and Buchner). While the word belief might be construed in all these ways, they do not correspond either to the construals of our commonsense psychology or of a scientific psychology.
Calcium/calmodulin-sensitive adenylyl cyclase as an example of a molecular associative integrator
Authors: Abrams Thomas W.
Published: February 2010

Evidence suggests that the Ca2+/calmodulin-sensitive adenylyl cyclase may play a key role in neural plasticity and learning inAplysia, Drosophila, and mammals. This dually-regulated enzyme has been proposed as a possible site of stimulus convergence during associative learning. This commentary discusses the evidence that is required to demonstrate that a protein in a second messenger cascade actually functions as a molecular site of associative integration. It also addresses the issue of how a dually-regulated protein could contribute to the temporal pairing requirements of classical conditioning: that relationship between stimuli display both temporal contiguity and predictability.
Reduced cytoplasmic calcium concentration may be both necessary and sufficient for photoreceptor light adaptation
Authors: Matthews H. R. , Fain G. L.
Published: February 2010

Light adaptation is modulated almost exclusively by changes in intracellular Ca2+concentration, and other Ca2+-independent mechanisms are likely to play only a minor role. Changes in Ca2+imay be not only necessary for light adaptation to take place but sufficient to cause it.
Nuclear magnetic resonance studies on the structure and function of rhodopsin
Authors: Smith Steven O.
Published: February 2010

Magic angle spinning (MAS) NMR methods provide a means of obtaining high resolution structural data on rhodopsin and its photoin termediates. Current work has focused on the structure of the retinal chromophore and its interactions with surrounding protein charges. The recent development of MAS NMR methods for measuring internuclear distances with a resolution of ∼0.2 will complement diffraction methods for addressing key mechanistic questions.
Evidence that the type I adenylyl cyclase may be important for neuroplasticity: Mutant mice deficient in the gene for type I adenylyl cyclase show altered behavior and LTP
Authors: Xia Zhengui , Storm Daniel R.
Published: February 2010

The regulatory properties of the neurospecific, type I adenylyl cyclase and its distribution within brain have suggested that this enzyme may be important for neuroplasticity. To address this issue, the murine, Ca2+-stimulated adenylyl cyclase (type I), was inactivated by targeted mutagenesis. Ca2+-stimulated adenylyl cyclase activity was reduced 40% to 60% in the hippocampus, neocortex, and cerebellum. Long term potentiation in the CA1 region of the hippocampus from mutants was perturbed relative to controls. Both the initial slope and maxim um extent of changes in synaptic response were reduced. Although mutant mice learned to find a hidden platform normally in the Morris water task, they did not display a preference for the region where the platform had been when it was removed. The behavioral phenotype of these mice is very similar to that exhibited by mice which have been surgically lesioned in the hippocampus. These results indicate that disruption of the gene for the type I adenylyl cyclase produces changes in spatial memory and indicate that the cAMP signal transduction pathway may play an important role for synaptic plasticity.
The sociobiology of sociopathy: An integrated evolutionary model
Authors: Mealey Linda
Published: February 2010

Sociopaths are “outstanding” members of society in two senses: politically, they draw our attention because of the inordinate amount of crime they commit, and psychologically, they hold our fascination because most ofus cannot fathom the cold, detached way they repeatedly harm and manipulate others. Proximate explanations from behavior genetics, child development, personality theory, learning theory, and social psychology describe a complex interaction of genetic and physiological risk factors with demographic and micro environmental variables that predispose a portion of the population to chronic antisocial behavior. More recent, evolutionary and game theoretic models have tried to present an ultimate explanation of sociopathy as the expression of a frequency-dependent life strategy which is selected, in dynamic equilibrium, in response to certain varying environmental circumstances. This paper tries to integrate the proximate, developmental models with the ultimate, evolutionary ones, suggesting that two developmentally different etiologies of sociopathy emerge from two different evolutionary mechanisms. Social strategies for minimizing the incidence of sociopathic behavior in modern society should consider the two different etiologies and the factors that contribute to them.
Continua outperform dichotomies
Authors: Baldwin John D.
Published: February 2010

Mealey's data do not support her dichotomous model of primary and secondary sociopathy; this data supports the view that there is a continuum of degrees of sociopathy, from zero to the maximal manifestation. There are multitudes of factors that can contribute to sociopathy – from both genetic and environmental sources – and the countless different mixes of them can produce multiple degrees and variations of sociopathic behavior.
A neuropsychology of deception and self-deception
Authors: Drake Roger A.
Published: February 2010

As more criminals are imprisoned, other individuals change their behavior to replace them, as predicted by the “floating niche” theory of strategic behavior. The physiological correlates of sociopathy suggest that research in cognitive neuroscience can lead toward a solution. Promising pathways include building upon current knowledge of self-deceit, the independence of positive and negative emotions, the lateralization of risk and caution, and the conditions promoting prosocial behavior.
Sociobiology, sociopathy, and social policy
Authors: Machalek Richard
Published: February 2010

Evolutionary analysis suggests that policies based on deterrence may cope effectively with primary sociopathy if the threat of punishment fits the crime in the cost/benefit calculus of the sociopath, not that of the public. On the other hand, policies designed to offset serious disadvantage in social competition may help inhibit the development of secondary sociopathy, rather than deter its expression.
Is the distinction between primary and secondary sociopaths a matter of degree, secondary traits, or nature vs. nurture?
Authors: Zuckerman Marvin
Published: February 2010

Psychopathy has as its central traits socialization, sensation seeking, and impulsivity. These are combined in a supertrait: Impulsive Unsocialized Sensation Seeking (ImpUSS). Secondary types are defined by combinations of ImpUSS and neuroticism or sociability. All broad personality traits have both genetic and environmental determination, and therefore different etiologies (primary as genetic, secondary as environmental) for primary and secondary sociopathy are unlikely.
Token-identity, consciousness, and the connection principle
Authors: Schröder Jürgen
Published: February 2010

Searle's (1990) argument for the “Connection Principle” seems to rest on a confusion between ontological and epistemological claims. The potential consciousness of a mental state does not yield the same effect as does its actual consciousness, namely, the preservation of aspectual shape. Searle's distinction between the consciousness of an intentional object and that of a mental state, which is meant to counter the objection that deep unconscious rules cease to be deep once they become conscious, fails to do its appointed task.
Are single-cell data sufficient for testing neural network models?
Authors: Ahissar Ehud
Published: February 2010

Persistent activity can be the product of mechanisms other than attractor reverberations. The single-unit data presented by Amit cannot discriminate between the different mechanisms. In fact, single-unit data do not appear to be adequate for testing neural network models.
The functional meaning of reverberations for sensoric and contextual encoding
Authors: Klimesch Wolfgang
Published: February 2010

Amit argues that the local neuronal spike rate that persists (reverberating) in the absence of the eliciting stimulus represents the code of the eliciting stimulus. Based on the general argument that the inferred functional meaning of reverberation depends in part on the type of representational assumptions, reverberations may only be important for the encoding of contextual information.
The contents of consciousness: A neuropsychological conjecture
Authors: Gray Jeffrey A.
Published: February 2010

Drawing on previous models of anxiety, intermediate memory, the positive symptoms of schizophrenia, and goal-directed behaviour, a neuropsychological hypothesis is proposed for the generation of the contents of consciousness. It is suggested that these correspond to the outputs of a comparator that, on a moment-by-moment basis, compares the current state of the organism's perceptual world with a predicted state. An outline is given of the information-processing functions of the comparator system and of the neural systems which mediate them. The hypothesis appears to be able to account for a number of key features of the contents of consciousness. However, it is argued that neitherthis nor any existing comparable hypothesis is yet able to explain why the brain should generate conscious experience of any kind at all.
Possible roles for a predictor plus comparator mechanism in human episodic recognition memory and imitative learning
Authors: Dennis Simon , Humphreys Michael
Published: February 2010

This commentary is divided into two parts. The first considers a possible role for Gray's predictor plus comparator mechanism in human episodic recognition memory. It draws on the computational specifications of recognition outlined in Humphreys et al. (1994) to demonstrate how the logically necessary components of recognition tasks might be mapped onto the mechanism. The second part demonstrates how the mechanism outlined by Gray might be implicated in a form of imitative learning suitable for the acquisition of complex tasks.
Perspective, reflection, transparent explanation, and other minds
Authors: Hurley S. L.
Published: February 2010

Perspective and reflection (whether involving conceptual or nonconceptual content) have each been considered in some way basic to phenomenal consciousness. Each has possible evolutionary value, though neither seems sufficient for consciousness. Consider an account of consciousness in terms of the combination of perspective and reflection, its relationship to the problem of other minds, and its capacity to inherit evolutionary explanation from its components.
Information synthesis in cortical areas as an important link in brain mechanisms of mind
Authors: Ivanitsky Alexei M.
Published: February 2010

To explore the mechanism of sensation correlations between EP (evoked potential) component amplitude and signal detection indices (d' and criterion) were studied. The time of sensation coincided with the peak latency of those EP components that showed a correlation with both indices. The components presumably reflected information synthesis in projection cortical neurons. A mechanism providing the synthesis process is proposed.
Septohippocampal comparator: Consciousness generator or attention feedback loop?
Authors: Kinsbourne Marcel
Published: February 2010

As Gray insists, his comparator model proposes a brute correlation only – of consciousness with septohippocampal output. I suggest that the comparator straddles a feedback loop that boosts the activation ofnovelrepresentations, thus helping them feature in present or recollected experience. Such a role in organizing conscious contents would transcend correlation and help explain how consciousness emerges from brain function.
Comparators, functions, and experiences
Authors: Merskey Harold
Published: February 2010

The comparator model is insufficient for three reasons. First, consciousness is involved in the process of comparison as well as in the output. Second, we still do not have enough neurophysiological information to match the events of consciousness, although such knowledge is growing. Third, the anatomical localisation proposed can be damaged bilaterally but consciousness will persist.
The limits of neurophysiological models of consciousness
Authors: Velmans Max
Published: February 2010

This commentary elaborates on Gray's conclusion that his neurophysiological model of consciousness might explain how consciousness arises from the brain, but does not address how consciousness evolved, affects behaviour or confers survival value. The commentary argues that such limitations apply to all neurophysiological or other thirdperson perspective models. To approach such questions the first-person nature of consciousness needs to be taken seriously in combination with third-person models of the brain.
Is the multi-joint pointing movement model applicable to equilibrium control during upper trunk movements?
Authors: Alexandrov Alexey , Frolov Alexander , Massion Jean
Published: February 2010

Two aspects of the target article, (1) the extension of the equilibrium point theory to multi-joint movements, and (2) the consequence that the EMG pattern is not directly controlled by the central nervous system (CNS), are discussed in light of the experiments on upper trunk bending in humans. The principle component kinematic analysis and the analysis of the EMG data, obtained under microgravity and additional loading conditions, support the application of Feldman and Levin's for multi-joint pointing movement to equilibrium control during upper trunk movement.
Moving models of motion forward: Explication and a new concept
Authors: Fikes Thomas G. , Townsend James T.
Published: February 2010

We affirm the dynamical systems approach taken by Feldman and Levin, but argue that a more mathematically rigorous and standard exposition of the model according to dynamical systems theory would greatly increase readability and testability. Such an explication would also have heuristic value, suggesting new variations of the model. We present one such variant, a new solution to the redundancy problem.
The case of the missing CVs: Multi-joint primitives
Authors: Giszter Simon
Published: February 2010

The search for simplifying principles in motor control motivates the target article. One method that the CNS uses to simplify the task of controlling a limb's mechanical properties is absent from the article. Evidence from multi-joint, force-field measurements and from kinematics that points to the existence of multi-joint primitives as control variables is discussed.
Twisted pairs: Does the motor system really care about joint configurations?
Authors: Haggard Patrick , Miall Chris , Stein John
Published: February 2010

Extrapersonal frames of reference for aimed movements are representationally convenient. They may, however, carry associated costs when the movement is executed in terms of the complex coordination of multiple joints they require. Studies that have measured both fingertip and joint paths suggest the motor systems may seek a compromise between simplicity of extrapersonal spatial representation and computational simplicity of multi-joint execution.
Frameworks on shifting sands
Authors: lngvaldsen R. , Whiting H.T.A.
Published: February 2010

Feldman and Levin present a model for movement control in which the system is said to seek equilibrium points, active movement being produced by shifting frames of reference in space. It is argued that whatever merit this model might have is limited to an understanding of “the how” and not “the why” we move. In this way the authors seem to be forced into a dualistic position leaving the upper level of the proposed control hierarchy “floating.”
Spatial frames for motor control would be commensurate with spatial frames for vision and proprioception, but what about control of energy flows?
Authors: Pagano Christopher C. , Bingham Geoffrey P.
Published: February 2010

The model identifies a spatial coordinate frame within which the sensorimotor apparatus produces movement. Its spatial nature simplifies its coupling with spatial reference frames used concurrently by vision and proprioception. While the positional reference frame addresses the performance of spatial tasks, it seems to have little to say about movements involving energy expenditure as the principle component of the task.
The λ model: Can it walk?
Authors: Patla Aftab E.
Published: February 2010

Generation of swing phase limb trajectory over obstacles during locomotion should be a reasonable test for the λ model proposed by Feldman and Levin. The observed features such as lack of simple amplitude scaling of endpoint (toe) trajectories for different obstacle heights, complex shaped toe velocity profiles, and exploitation of passive intersegmental dynamics to control limb elevation cannot be adequately explained by the λ model.
The need for a theory of evidential weight
Authors: Cohen L. Jonathan
Published: February 2010

There is a familiar risk of antinomy if fromxisEand p(xisH/xisE) =rit is permissible to infer p(xisH) =r, and what Carnap (1950) called “The requirement of total evidence” will not prevent such antinomies satisfactorily. What is needed instead is a properly developed theory of evidential weight.
Throwing out the baby with the bathwater? Let's not overstate the overselling of the base rate fallacy
Authors: Thomsen Cynthia J. , Borgida Eugene
Published: February 2010

Koehler's summary and critique of research on the base rate fallacy is cogent and persuasive. However, he may have overstated the case, and his suggestions for future research may be too restrictive. We agree that methodological approaches to this topic should be broadened, but we argue that experimental laboratory research and the Bayesian normative standard are useful and should not be abandoned.
Can children with autism integrate first and third person representations?
Authors: Baron-Cohen Simon
Published: February 2010

Barresi & Moore contrast two theories of autism: (1) in autism there is a general inability to integrate first and third person information (of any kind), and (2) in autism there is a specific inability to represent an agent's perceptual or volitional mental state being about another agents mental state. Two lines of experimental evidence suggest that the first of these is too broad, favoring instead the more specific “theory of mind” account.
Development of social emotions and constructive agents
Authors: Ze'ev Aaron Ben , Oatley Keith
Published: February 2010

The psychology of emotions illuminates the questions of intentional capacities raised by Barresi & Moore (B&M). Complex emotions require the development of a sense of self and are based on social comparisons between mainly imagined objects. The fourth level in B&M's framework requires something like a constructive agent rather than a mental agent.
On the dangers of oversimulation
Authors: Csibra Gergely , Gergely György
Published: February 2010

Barresi & Moore fail to provide a satisfactory account for the development of social understanding because of (1) their ambiguous characterization of the relationship between the intentional schema and shared intentional activities, (2) their underestimation of the representational capacities of infants, and (3) their overreliance on the simulationist assumption that understanding others is tantamount to sharing their experience.
Second person intentional relations and the evolution of social understanding
Authors: Gomez Juan Carlos
Published: February 2010

Second person intentional relations, involving intentional activities directed at the perceptor, are qualitatively different from first and third person relations. They generate a peculiar, bidirectional kind of intentionality, especially in the realm of visual perception. Systems specialized in dealing with this have been selected by evolution. These systems can be considered to be the evolutionary precursors to the human theory of mind.
Ontogeny, evolution, and folk psychology
Authors: Povinelli Daniel J. , Zebouni Mia C. , Prince Christopher G.
Published: February 2010

Barresi & Moore assume an equivalence between ontogenetic and evolutionaiy transformations of social understanding. The mechanisms of evolution allow for novel structures to arise, both through terminal addition and through the onset of novel pathways at time points that precede the end points of ancestral pathways. Terminal addition may not be the appropriate model for the evolution of human object-directed imitation, intermodal equivalence, or joint attention.
The role of vocalization, memory retrieval, and external symbols in cognitive evolution
Authors: Donald Merlin
Published: February 2010

The human vocal apparatus is part of a vertically integrated system, and I agree withLicbennanthat modern high-speed phonology co-evolved with our capacity for grammar.Olsonand I agree that some distinctly human thought skills appear to be fairly recent cultural acquisitions related to the introduction of new symbolic technologies and external (that is, nonbiological) memory storage.Stenning's concern with my use of the term “episodic” can be resolved by distinguishing between episodic storage and retrieval.Baum's suggestions regarding courtship and cognitive evolution seem to apply better to mimetic expression than to language.
Sexual selection and sex differences in mathematical abilities
Authors: Geary David C.
Published: February 2010

The principles of sexual selection were used as an organizing framework for interpreting cross-national patterns of sex differences in mathematical abilities. Cross-national studies suggest that there are no sex differences in biologically primary mathematical abilities, that is, for those mathematical abilities that are found in all cultures as well as in nonhuman primates, and show moderate heritability estimates. Sex differences in several biologically secondary mathematical domains (i.e., those that emerge primarily in school) are found throughout the industrialized world. In particular, males consistently outperform females in the solving of mathematical word problems and geometry. Sexual selection and any associated proximate mechanisms (e.g., sex hormones) influence these sex differences in mathematical performance indirectly. First, sexual selection resulted in greater elaboration in males than in females of the neurocognitive systems that support navigation in three-dimensional space. Knowledge implicit in these systems reflects an understanding of basic Euclidean geometry, and may thus be one source of the male advantage in geometry. Males also use more readily than females these spatial systems in problem-solving situations, which provides them with an advantage in solving word problems and geometry. In addition, sex differences in social styles and interests, which also appear to be related in part to sexual selection, result in sex differences in engagement iii mathematics-related activities, thus further increasing the male advantage in certain mathematical domains. A model that integrates these biological influences with sociocultural influences on the sex differences in mathematical performance is presented in this article.
Is there a comparative psychology of implicit mathematical knowledge?
Authors: Davis Hank
Published: February 2010

Geary suggests that implicit mathematical principles exist across human cultures and transcend sex differences. Is such knowledge present in animals as well, and is it sufficient to account for performance in all species, including our own? I attempt to trace the implications of Gearys target article for comparative psychology, questioning the exclusion of “subitizing” in describing human mathematical performance, and asking whether human researchers function as cultural agents with animals, elevating their implicit knowledge to secondary domains of numerical performance.
Some problematic links between hunting and geometry
Authors: Kimball Meredith M.
Published: February 2010

Geary's emphasis on hunting ignores the possible importance of other human activities, such as scavenging and gathering, in the evolution of spatial abilities. In addition, there is little evidence that links spatial abilities and math skills. Furthermore, such links have little practical importance given the small size of most differences and girls' superior performance in mathematics classrooms.
Able youths and achievement tests
Authors: Stanley Julian C. , Stumpf Heinrich
Published: February 2010

Achievement test differences between boys and girls and between young men and young women, mostly favoring males, extend far beyond mathematics. Such pervasive differences, illustrated here, may require an explanatory theory broader than Geary's.
Between-sex differences are often averaging artifacts
Authors: Thomas Hoben
Published: February 2010

The central problem in Geary's theory is how differences are conceptualized. Recent research has shown that between-sex differences on certain tasks are a consequence of averaging within sex differences. A mixture distribution models between-sex differences on several tasks well and does not appear congenial to a sexual-selection perspective.
Is the time ripe for integration of scales?
Authors: Amit Daniel J.
Published: February 2010

Some concepts relating to learned, structured functioning of local modules in neocortex are clarified in order to ensure that the integration from the small scale to the global attempted by Wright & Liley does not miss the target.
Levels, models, and brain activities: Neurodynamics is pluralistic
Authors: Érdi Péter
Published: February 2010

Some dichotomies related to modeling electrocortical activities are analyzed. Attractor neural networks versus biologically motivated models, near-equilibrium versus nonequilibrium processes, linear and nonlinear dynamics, stochastic and chaotic patterns, local and global scale simulation of cortical activities are discussed.
The ameliorating addict: An illusion reviewed
Authors: Bergman Jack , Miczek Klaus A.
Published: February 2010

It is difficult to accommodate compulsive drug use that destroys regulation by consequences in a unitary framework of melioration or maximization, especially as both are strategies of behavioral regulation. The “contradiction” of addictive behavior despite aversive consequences is an illusory issue because consequences that do not decrease addictive behavior cannot be considered punishing.
Control versus causation of addiction
Authors: Berridge Kent C. , Robinson Terry E.
Published: February 2010

Heyman explains useful ways to bring addictive drug use under environmental control. We doubt that relapse is explained by drug features such as immediate reinforcement, clouding of judgment, and so forth. Relapse may require explanation in terms of enduring sensitization of incentive neural substrates, but even if its causal assumptions are wrong, Heyman's model makes useful predictions for behavioral control.
Matching observation to addiction theory
Authors: Swift Robert M.
Published: February 2010

Over the years, many theories have been proposed to account for the aberrant behavior of drug dependent individuals. Heyman posits that the existing theories of drug dependence are inadequate to explain the complex processes inherent in human drug-taking. He proposes that incongruous behaviors that comprise addiction, such as continued drug use in spite of adverse consequences, can be explained by application of the matching law approach. While the matching law theory of addiction explains certain aspects of human behavior, its application to the area of addiction must be subjected to experimental verification.
Biology of language: Principle predictions and evidence
Authors: Pulvermüller Friedemann , Mohr Bettina , Preissl Hubert
Published: February 2010

Müller's target article aims to summarize approaches to the question of how language elements (phonemes, morphemes, etc.) and rules are laid down in the brain. However, it suffers from being too vague about basic assumptions and empirical predictions of neurobiological models, and the empirical evidence available to test the models is not appropriately evaluated. (1) In a neuroscientific model of language, different cortical localizations of words can only be based on biological principles. These need to be made explicit. (2) Evidence for and against word class differences could be evaluated more rigorously. (3) All (and only) humans are able to learn languages with complex syntactic structures; it is, therefore, not appropriate to deny innateness and universality of syntactic principles. The real question appears to be the following: Which neurobiological principles are the linguistic principles based on?
The epigenesis of regional specificity
Authors: Müller Ralph-Axel
Published: February 2010

Chomskyian claims of a genetically hard-wired and cognitively autonomous “universal grammar” are being promoted by generative linguistics as facts about language to the present day. The related doctrine of an evolutionary discontinuity in language emergence, however, is based on misconceptions about the notions of homology and preadaptation. The obvious lack of equivalence between symbolic communicative capacities in existing nonhuman primates and human language does not preclude common roots. Normal and disordered language development is strongly influenced by the genome, but there is no evidence for the existence of specific genes underlying “universal grammar.” In the mature brain, stages of language processing can be distinguished and “first-pass” syntactic analyses appear to precede semantic decoding. However, this partial seriality – as well as behavioral and clinical dissociations between lexical and functional categories – can be best described, not in terms of serially activated and discrete modules, but in terms of classes of cell assemblies that differ in their distributional properties. Whereas cell assemblies involved in semantic interpretation (“content word” assemblies) are widely distributed and are generally less vulnerable to focal lesion, those involved in structural decoding (functor assemblies) are primarily distributed within the left perisylvian cortices and are selectively vulnerable to left perisylvian lesion. These distributional differences are explained in terms of the perceptuomotor components involved in the acquisition of relevant representations. The emerging “motivated” or “toposemantic” brain regional specificity can only be accommodated with “soft” and maturational versions of modularity. The failure to reproduce double dissociations in current connectionist models is due to overly simple neuroscientific assumptions, notably that of overall equipotentiality. Linguistic models should not be expected to be “implemented” in the brain, but need to be constrained by neuroscientific evidence on how biological brains function.
Functional categories in L2 acquisition: Evidence of presence is not necessarily presence of evidence
Authors: Archibald John , Guilfoyle Eithne , Ritter Elizabeth
Published: February 2010

Epstein et al. fail to show that L2 learners have full access to UG because they do not explain the relationship between UG and functional categories (FCs). Nor do they provide an explanation of why learners with (supposed) full knowledge of FCs fail to use them in a native-like way.
Does second language grow?
Authors: Grewendorf Günther
Published: February 2010

The evidence that L2 learners have full access to UG is not convincing. The following will be shown: (1) The argument that L2 learners “expect” L2 to have particular properties rests on the conceptual confusion ofhaving the concept of language(in the sense of knowing the meaning of “language”) withhaving accessto UG. (2) The claim that L2 acquisition takes place under the constraints imposed by universal principles lacks empirical support. (3) The assumption that L2 learners assign new parameter values is based on a problematic example and remains unclear.
Can UG and L1 be distinguished in L2 acquisition?
Authors: Hale Ken
Published: February 2010

The contribution to L2-acquisition which comes from UG is conceptually distinct from that which comes from L1 (or from L1 and L2 jointly), but it is difficult to tease the two apart. The workings of deep, core principles (e.g., locality and subjacency) are so massively evident in L1 and L2 as to be of questionable use in the search for the contribution which is purely of UG.
L2 access to UG: Now you see it, now you don't
Authors: Harrington Michael
Published: February 2010

The confirmatory nature of the empirical evidence used to establish UG effects in L2 development is considered. Specific issues are also raised concerning the internal validity of Epstein et al.'s findings. It is concluded that the role of UG in adult L2 development will only be established when researchers better understand the interaction between the development of UG-constrained structural knowledge and the development of overall L2 proficiency.
Now for some facts, with a focus on development and an explicit role for the L1
Authors: Schwartz Bonnie D.
Published: February 2010

Curiously, two central areas are unaddressed by Epstein et al.: (i) L1A–L2A differences; (ii) L2 development. Here, findings relevant to (i) and (ii) – as well as their significance – are discussed. Together these form the basis for contesting Epstein et al.'s “Full Access” approach, but nonetheless analyses of the L2 data argue for UG-constrained L2A. Also discussed is the inadequacy of accounts (like Epstein et al.'s) without an explicit and prominent role for the L1.
Partial transfer, not partial access
Authors: Vainikka Anne , Young-Scholten Martha
Published: February 2010

Our results support the idea that adults have access to the principles and parameters of Universal Grammar (UG), contrary to Epstein et al.'s misrepresentation of our work as involvingpartial access toUG. For both LI and L2 acquisition, functional projections appear to develop in a gradual fashion, but in L2 acquisition there ispartial transferin that the lowest projection (VP) is transferred from the speaker's LI.
UG, the L1, and questions of evidence
Authors: White Lydia
Published: February 2010

Epstein, Flynn, and Martohardjono's presentation of the principal approaches to UG access in L2 acquisition is misleading; they have neglected the possibility that the L1 grammar forms the learner's initial representation of the L2, with subsequent modifications constrained by UG. Furthermore, their experimental data are open to several interpretations and are consistent with a number of different positions in the field.
Response intention and imagery processes: Locus, interaction, and contribution to motor learning
Authors: Kohl Robert M. , Fisicaro Sebastiano A.
Published: February 2010

By way of commentary on Jeannerod (1994), we propose that (1) intention, response imagery, and actual response processes carry equal weight in inferring from one process to another, (2) memory networks control intention, which interacts with imagery-based processing to control response imagery, and (3) response imagery will demonstrate learning effects better when imagery reconstruction and elaboration are emphasized and neutral retention tests are utilized.
Transcending inductive category formation in learning
Authors: Schank Roger C. , Collins Gregg C. , Hunter Lawrence E.
Published: February 2010

The inductive category formation framework, an influential set of theories of learning in psychology and artificial intelligence, is deeply flawed. In this framework a set of necessary and sufficient features is taken to define a category. Such definitions are not functionally justified, are not used by people, and are not inducible by a learning system. Inductive theories depend on having access to all and only relevant features, which is not only impossible but begs a key question in learning. The crucial roles of other cognitive processes (such as explanation and credit assignment) are ignored or oversimplified. Learning necessarily involves pragmatic considerations that can only be handled by complex cognitive processes.

We provide an alternative framework for learning according to which category definitions must be based on category function. The learning system invokes other cognitive processes to accomplish difficult tasks, makes inferences, analyses and decides among potential features, and specifies how and when categories are to be generated and modified. We also examine the methodological underpinnings of the two approaches and compare their motivations.
Research on self-control: An integrating framework
Authors: Logue A. W.
Published: February 2010

The tendency to choose a larger, more delayed reinforcer over a smaller, less delayed one has frequently been termed “selfcontrol.” Three very different research traditions – two models emphasizing the control of local contingencies of reinforcement (Mischel's social learning theory and Herrnstein's matching law) and molar maximization models (specifically optimal foraging theory) – have all investigated behavior within the self-control paradigm. A framework is proposed to integrate research from all three research areas. This framework consists of three parts: a procedural analysis, a causal analysis, and a theoretical analysis. The procedural analysis provides a common procedural terminology for all three areas. The causal analysis establishes that, in all three research traditions, self-control varies directly with the current physical values of the reinforcers; that is, choices increase with reinforcer amount and decrease with reinforcer delay. But self-control also varies according to past events to which a subject has been exposed, and according to current factors other than the reinforcers. Each of the three models has therefore incorporated these indirect effects on self-control by postulating unobservable mechanisms. In all three cases, these mechanisms represent a subject's behavior as a function of a perceived environment. The theoretical analysis demonstrates that evolutionary theory can encompass the research from all three areas by considering differences in the adaptiveness of self-control in different situations. This integration provides a better and more predictive description of self-control.
Explanatory coherence
Authors: Thagard Paul
Published: February 2010

This target article presents a new computational theory of explanatory coherence that applies to the acceptance and rejection of scientific hypotheses as well as to reasoning in everyday life. The theory consists of seven principles that establish relations of local coherence between a hypothesis and other propositions. A hypothesis coheres with propositions that it explains, or that explain it, or that participate with it in explaining other propositions, or that offer analogous explanations. Propositions are incoherent with each other if they are contradictory. Propositions that describe the results of observation have a degree of acceptability on their own. An explanatory hypothesis is accepted if it coheres better overall than its competitors. The power of the seven principles is shown by their implementation in a connectionist program called ECHO, which treats hypothesis evaluation as a constraint satisfaction problem. Inputs about the explanatory relations are used to create a network of units representing propositions, while coherence and incoherence relations are encoded by excitatory and inhibitory links. ECHO provides an algorithm for smoothly integrating theory evaluation based on considerations of explanatory breadth, simplicity, and analogy. It has been applied to such important scientific cases as Lavoisier's argument for oxygen against the phlogiston theory and Darwin's argument for evolution against creationism, and also to cases of legal reasoning. The theory of explanatory coherence has implications for artificial intelligence, psychology, and philosophy.
When is it good to believe bad things?
Authors: Ackerman Joshua M. , Shapiro Jenessa R. , Maner Jon K.
Published: January 2010

Positive and negative misbeliefs both may have evolved to serve important adaptive functions. Here, we focus on the role of negative misbeliefs in promoting adaptive outcomes within the contexts of romantic relationships and intergroup interactions. Believing bad things can paradoxically encourage romantic fidelity, personal safety, competitive success, and group solidarity, among other positive outcomes.
Non-instrumental belief is largely founded on singularity
Authors: Ainslie George
Published: January 2010

The radical evolutionary step that divides human decision-making from that of nonhumans is the ability to excite the reward process for its own sake, in imagination. Combined with hyperbolic over-valuation of the present, this ability is a potential threat to both the individual's long term survival and the natural selection of high intelligence. Human belief is intrinsically “unfounded” or under-founded, which may or may not be adaptive.
False beliefs and naive beliefs: They can be good for you
Authors: Bertamini Marco , Casati Roberto
Published: January 2010

Naive physics beliefs can be systematically mistaken. They provide a useful test-bed because they are common, and also because their existence must rely on some adaptive advantage, within a given context. In the second part of the commentary we also ask questions about when a whole family of misbeliefs should be considered together as a single phenomenon.
Positive illusions and positive collusions: How social life abets self-enhancing beliefs
Authors: Brown Jonathon D.
Published: January 2010

Most people hold overly (though not excessively) positive self-views of themselves, their ability to shape environmental events, and their future. These positive illusions are generally (though not always) beneficial, promoting achievement, psychological adjustment, and physical well-being. Social processes conspire to produce these illusions, suggesting that affiliation patterns may have evolved to nurture and sustain them.
On the adaptive advantage of always being right (even when one is not)
Authors: Gjersoe Nathalia L. , Hood Bruce M.
Published: January 2010

We propose another positive illusion – overconfidence in the generalisability of one's theory – that fits with McKay & Dennett's (M&D's) criteria for adaptive misbeliefs. This illusion is pervasive in adult reasoning but we focus on its prevalence in children's developing theories. It is a strongly held conviction arising from normal functioning of the doxastic system that confers adaptive advantage on the individual.
A positive illusion about “positive illusions”?
Authors: Konečni Vladimir J.
Published: January 2010

Rather than being a genuine adaptation, “positive illusions” are examples of doxastically uncommitted policies implemented at both the individual and societal levels. Even when they are genuine misbeliefs, most positive illusions are not evolved but ephemeral – a phenomenon limited to a particular social and economic moment. They are essentially a consumer response to messages from the pop-psychology industry in the recently terminated era of easy credit.
Benign folie à deux: The social construction of positive illusions
Authors: Krebs Dennis L. , Denton Kathy
Published: January 2010

McKay & Dennett (M&D) have done an admirable job of distinguishing among various forms of misbelief and evaluating the idea that they stem from evolved mental mechanisms. We argue that a complete account of misbeliefs must attend to the role that others play in creating and maintaining positive illusions.
Are beliefs the proper targets of adaptationist analyses?
Authors: Liddle James R. , Shackelford Todd K.
Published: January 2010

McKay & Dennett's (M&D's) description of beliefs, and misbeliefs in particular, is a commendable contribution to the literature; but we argue that referring to beliefs as adaptive or maladaptive can cause conceptual confusion. “Adaptive” is inconsistently defined in the article, which adds to confusion and renders it difficult to evaluate the claims, particularly the possibility of “adaptive misbelief.”
Culturally transmitted misbeliefs
Authors: Sperber Dan
Published: January 2010

Most human beliefs are acquired through communication, and so are most misbeliefs. Just like the misbeliefs discussed by McKay & Dennett (M&D), culturally transmitted misbeliefs tend to result from limitations rather than malfunctions of the mechanisms that produce them, and few if any can be argued to be adaptations. However, the mechanisms involved, the contents, and the hypothetical adaptive value tend to be specific to the cultural case.
Belief in evolved belief systems: Artifact of a limited evolutionary model?
Authors: Wereha Tyler J. , Racine Timothy P.
Published: January 2010

Belief in evolved belief systems stems from using a population-genetic model of evolution that misconstrues the developmental relationship between genes and behaviour, confuses notions of “adapted” and “adaptive,” and ignores the fundamental role of language in the development of human beliefs. We suggest that theories about the evolution of belief would be better grounded in a developmental model of evolution.
Extending the range of adaptive misbelief: Memory “distortions” as functional features
Authors: Boyer Pascal
Published: January 2010

A large amount of research in cognitive psychology is focused on memory distortions, understood as deviations from various (largely implicit) standards. Many alleged distortions actually suggest a highly functional system that balances the cost of acquiring new information with the benefit of relevant, contextually appropriate decision-making. In this sense many memories may be examples of functionally adaptive misbelief.
Why we don't need built-in misbeliefs
Authors: Dweck Carol S.
Published: January 2010

In this commentary, I question the idea that positive illusions are evolved misbeliefs on the grounds that positive illusions are often maladaptive, are not universal, and may be by-products of existing mechanisms. Further, because different beliefs are adaptive in different situations and cultures, it makes sense to build in a readiness to form beliefs rather than the beliefs themselves.
Error management theory and the evolution of misbeliefs
Authors: Haselton Martie G. , Buss David M.
Published: January 2010

We argue that many evolved biases produced through selective forces described by error management theory are likely to entail misbeliefs. We illustrate our argument with the male sexual overperception bias. A misbelief could create motivational impetus for courtship, overcome the inhibiting effects of anxiety about rejection, and in some cases transform an initially sexually uninterested woman into an interested one.
Are delusions biologically adaptive? Salvaging the doxastic shear pin
Authors: Mishara Aaron L. , Corlett Phil
Published: January 2010

In their target article, McKay & Dennett (M&D) conclude that only “positive illusions” are adaptive misbeliefs. Relying on overly strict conceptual schisms (deficit vs. motivational, functional vs. organic, perception vs. belief), they prematurely discount delusions asbiologicallyadaptive. In contrast to their view that “motivation” plays a psychological but not a biological function in a two-factor model of the forming and maintenance of delusions, we propose asingleimpairment in prediction-error–driven (i.e., motivational) learning in three stages in which delusions play a biologically adaptive role.
