Reasons for the preference for symmetry
Authors: Reber Rolf
Published: July 2008

Why did Homo erectus begin to craft symmetric tools? A parsimonious account assumes that preference for symmetry is inherent in all visual systems. This preference can be explained by a broader preference for perceptual fluency. The perceptual fluency account does not assume that selection for mate health or the production of symbolic art is a prerequisite for symmetry preference.
Symmetry and human spatial cognition: An alternative perspective
Authors: Silverman Irwin
Published: July 2008

Wynn's thesis that the acquisition of the rules of symmetry comprised the formative factor in the evolution of human spatial cognition is questioned on several grounds, including the ubiquity of symmetry across species and the apparent hard-wired nature of its evolution in both humans and animals.
Tools evolve: The artificial selection and evolution of Paleolithic stone tools
Authors: Simão Jorge
Published: July 2008

I claim that the increase in complexity in the (known) trace of Paleolithic stone tools can be parsimoniously explained by postulating the emergence of effective mechanisms for the social transmission of representations. I propose that Paleolithic tools, similar to more contemporary tools, were subject to a process of evolution by artificial selection based on functionality.
Footloose and fossil-free no more: Evolutionary psychology needs archaeology
Authors: Stone Valerie E.
Published: July 2008

Evolutionary theories of human cognition should refer to specific times in the primate or hominid past. Though alternative accounts of tool manufacture from Wynn's are possible (e.g., frontal lobe function), Wynn demonstrates the power of archaeology to guide cognitive theories. Many cognitive abilities evolved not in the “Pleistocene hunter-gatherer” context, but earlier, in the context of other patterns of social organization and foraging.
The SOC framework and short-term memory
Authors: Murray David J.
Published: July 2008

Using a particular formula for quantifying the effortlessness that Perruchet & Vinter suggest accompanies the detection of repetition among a set of representations concurrently in consciousness, it is shown that both the Sternberg function and the Cavanagh function, associated with immediate probed recognition tasks and memory span tasks, can be predicted.
Thinking and doing in cognitive archaeology: Giving skill its due
Authors: Stout Dietrich
Published: July 2008

Wynn shows that intentionally standardized artifacts (handaxes) provide evidence of the ability to conceptualize form (symmetry). However, such conceptual ability is not sufficient for the actual production of these forms. Stone knapping is a concrete skill that is acquired in the real world. Appreciation of its perceptual-motor foundations and the broader issues surrounding skill acquisition may lead to further important insights into human cognitive evolution.
The computational baby, the classical bathwater, and the middle way
Authors: O'Brien Gerard , Opie Jon
Published: July 2008

We are sympathetic with the broad aims of Perruchet & Vinter's “mentalistic” framework. But it is implausible to claim, as they do, that human cognition can be understood without recourse to unconsciously represented information. In our view, this strategy forsakes the only available mechanistic understanding of intelligent behaviour. Our purpose here is to plot a course midway between the classical unconscious and Perruchet &Vinter's own noncomputational associationism.
Symmetry for the sake of symmetry, or symmetry for the sake of behavior?
Authors: Wagman Jeffrey B.
Published: July 2008

Wynn suggests that the imposition of symmetry on stone tools is indicative of the evolutionary development of cognitive abilities of the tool makers, particularly that of creating mental images. I suggest that it is more likely indicative of the evolutionary development of the perceptual ability to detect resources for behavior of hand-held objects.
The fossil evidence for spatial cognition
Authors: Weaver Anne H.
Published: July 2008

Wynn's model for the evolution of spatial cognition is well supported by fossil evidence from brain endocasts, and from neurological studies of the cerebellum and the posterior parietal region of the cerebral cortex. Wynn's intriguing hypothesis that the spatial skill reflected in artifacts is an index of navigational ability, could be further explored by an analysis of lithic transport patterns.
Intentions, goals, and the archaeological record
Authors: Welshon Rex
Published: July 2008

The underdetermination of intentional explanation by motor behavior complicates inferences drawn from preserved artifacts in the archaeological record to intentions in their production. Without knowledge of a producer's intentions, inferences drawn from those intentions to required cognitive abilities for having those intentions is also complicated.
The devil in the details
Authors: Wynn Thomas
Published: July 2008

Despite challenges on minimum necessary competence, intentionality, reliability, and context, the example of cognitive archaeology presented in the target article holds up well. The commentaries also present perspectives on cognition and symmetry that suggest an alternative to the target article's characterization of the cognitive abilities of early Homo erectus. However, the major conclusion of the initial argument – that the human ability to coordinate shape recognition and spatial cognition evolved hundreds of thousands of year ago in conditions unlike those of the modern world – remains intact.
Does the SOC theory avoid unconscious rule use?
Authors: Seger Carol A.
Published: July 2008

There are striking similarities between Perruchet & Vinter's SOC theory and the theories that they claim to be in opposition to. First, both kinds of theory lead to the induction of knowledge of complex patterns in the environment that serve the function of rules. Second, both involve unconscious mental processes of induction resulting in at least some conscious knowledge.
Remember the old masters!
Authors: Shanon Benny
Published: July 2008

Perruchet & Vinter (P&V) ground their arguments in a view they call “the mentalistic tradition.” Here I point out that such a view has already been advocated by two old masters of psychological science, William James and James Gibson, as well as by the philosopher Merleau-Ponty. In fact, in the writings of these older thinkers, arguments very similar to those presented in the target article are found.
Hemineglect, extinction, and the importance of conscious processing
Authors: Siéroff Eric
Published: July 2008

Neuropsychological studies on hemineglect and extinction show that “neglected” or “extinguished” stimuli can access a semantic level. However, processing of these stimuli is usually not accomplished at the same level as non-neglected stimuli. These data are compatible with Perruchet & Vinter's hypothesis of the importance of consciousness in the construction of representations and knowledge.
The emergence of consciousness: BUC versus SOC
Authors: Sun Ron
Published: July 2008

This commentary suggests that there are two distinct types of interacting cognitive processes. Conscious processes emerge from unconscious processes. The key problem of SOC is that it uses an overly narrow notion of the “cognitive unconscious” to show that the “cognitive unconscious” is not necessary. Yet, it has little to say about the roles of conscious and unconscious processes in general.
Trading automatic/nonautomatic for unconscious/conscious
Authors: Tzelgov Joseph
Published: July 2008

In this commentary I show that the SOC framework implies automaticity of both the materialization of phenomenological conscious experience and the application of the primitives resulting from the emergence of consciousness. In addition, SOC implies that cognition refers to conscious experience. Consequently, I propose automatic/nonautomatic instead of unconscious/conscious as the basic contrast characterizing human cognition.
Could phenomenal consciousness function as a cognitive unconscious?
Authors: Velmans Max
Published: July 2008

Evidence for unconscious semantic representation suggests that a cognitive unconscious exists. Phenomenal consciousness cannot easily be shown to deal with complex cognitive operations such as those involved in language translation and creativity. A self-organising phenomenal consciousness that controls brain functions also runs into mind/body problems (well recognised in the consciousness studies literature) that Perruchet & Vinter must address.
Contrasts and dissociations suggest qualitative differences between conscious and unconscious processes
Authors: Wolters Gezinus , Phaf R. Hans
Published: July 2008

The authors reject a computationally powerful unconscious. Instead, they suggest that simple unconscious processes give rise to complex conscious representations. We discuss evidence showing contrastive effects of conscious and unconscious processes, suggesting a distinction between these types of processes. In our view, conscious processes often serve to correct or control negative consequences of relatively simple unconscious processes.
The self-organizing consciousness as an alternative model of the mind
Authors: Perruchet Pierre , Vinter Annie
Published: July 2008

Through the concept of self-organizing consciousness (SOC), we posit that the dynamic of the mind stems from the recurrent interplay between the properties of conscious experiences and the properties of the world, hence making it unnecessary to postulate the existence of an unconscious mental level. In contrast, arguments are provided by commentators for the need for a functional level of organization located between the neural and the conscious. Other commentaries challenge us concerning the ability of our model to account for specific phenomena in the domains of language, reasoning, incubation, and creativity. The possibility of unconscious semantic access and other alleged instances of adapted performance in the absence of any conscious counterpart are also put forth as evidence against our view. Our response emphasizes the fact that opponents to our model often present as factual, theory-free evidence which is in fact nothing more than the postulates underlying the classical computational framework.
Précis of Foundations of Language: Brain, Meaning, Grammar, Evolution,
Authors: Jackendoff Ray
Published: July 2008

The goal of this study is to reintegrate the theory of generative grammar into the cognitive sciences. Generative grammar was right to focus on the child's acquisition of language as its central problem, leading to the hypothesis of an innate Universal Grammar. However, generative grammar was mistaken in assuming that the syntactic component is the sole course of combinatoriality, and that everything else is “interpretive.” The proper approach is a parallel architecture, in which phonology, syntax, and semantics are autonomous generative systems linked by interface components. The parallel architecture leads to an integration within linguistics, and to a far better integration with the rest of cognitive neuroscience. It fits naturally into the larger architecture of the mind/brain and permits a properly mentalistic theory of semantics. It results in a view of linguistic performance in which the rules of grammar are directly involved in processing. Finally, it leads to a natural account of the incremental evolution of the language capacity.
Working memory retention systems: A state of activated long-term memory
Authors: Ruchkin Daniel S. , Grafman Jordan , Cameron Katherine , Berndt Rita S.
Published: July 2008

High temporal resolution event-related brain potential and electroencephalographic coherence studies of the neural substrate of short-term storage in working memory indicate that the sustained coactivation of both prefrontal cortex and the posterior cortical systems that participate in the initial perception and comprehension of the retained information are involved in its storage. These studies further show that short-term storage mechanisms involve an increase in neural synchrony between prefrontal cortex and posterior cortex and the enhanced activation of long-term memory representations of material held in short-term memory. This activation begins during the encoding/comprehension phase and evidently is prolonged into the retention phase by attentional drive from prefrontal cortex control systems. A parsimonious interpretation of these findings is that the long-term memory systems associated with the posterior cortical processors provide the necessary representational basis for working memory, with the property of short-term memory decay being primarily due to the posterior system. In this view, there is no reason to posit specialized neural systems whose functions are limited to those of short-term storage buffers. Prefrontal cortex provides the attentional pointer system for maintaining activation in the appropriate posterior processing systems. Short-term memory capacity and phenomena such as displacement of information in short-term memory are determined by limitations on the number of pointers that can be sustained by the prefrontal control systems.
Colors as explainers?
Authors: Botterell Andrew
Published: July 2008

Byrne & Hilbert (B&H) argue that colors are reflectance properties of objects. They also claim that a necessary condition for something's being a color is that it causally explain – or be causally implicated in the explanation of – our perceptions of color. I argue that these two positions are in conflict.
Attention-based maintenance of speech forms in memory: The case of verbal transformations
Authors: Abry Christian , Sato Marc , Schwartz Jean-Luc , Loevenbruck Hélène , Cathiard Marie-Agnès
Published: July 2008

One of the fundamental questions raised by Ruchkin, Grafman, Cameron, and Berndt's (Ruchkin et al.'s) interpretation of no distinct specialized neural networks for short-term storage buffers and long-term memory systems, is that of the link between perception and memory processes. In this framework, we take the opportunity in this commentary to discuss a specific working memory task involving percept formation, temporary retention, auditory imagery, and the attention-based maintenance of information, that is, the verbal transformation effect.
Huygens versus Fermat: No clear winner
Authors: Schoemaker Paul J. H.
Published: July 2008

How should we assess the appeal of multiple scientific theories when they can all explain a particular empirical phenomenon of interest? We contrast Huygens' and Fermat's explanations of the law of refraction of light and find that neither dominates the other when considering multiple criteria for assessing the overall appeal of a scientific theory. The absence of teleology in Huygens' account is a strong plus compared to Fermat's. But Huygens' wave theory scores less well with respect to other desiderata for a scientific theory. In this case, there does not appear to be a clear winner, nor need there be one.
Do opponent process theories help physicalism about color?
Authors: Broackes Justin
Published: July 2008

Byrne & Hilbert (B&H) give some excellent replies to the objections to realism about color. However, the particular form of realism they propose, based on opponent processing, prompts several challenges. Why characterize a color by its tendency to produce an intermediate brain signal, rather than in terms of the final effect – either a perception or a neural substrate for it? At the level of the retina, and even of the cortex, there are processes that partly parallel the structure of color experience; but the correspondence is not exact. Must we assume that there is any place in the brain where an exact structural correspondence is found? At the level of psychophysical functioning, there is indeed opponency; but it is not clear that this gives us the kind of type-reduction that B&H want.
New data: Old pitfalls
Authors: Baddeley Alan
Published: July 2008

Ruchkin et al.'s theoretical conclusions reflect two venerable fallacies. They confound an experimental paradigm with a theoretical concept, and they assume that features of the paradigm that are most readily detected by their methods provide an adequate account of the operation of the theoretical system. This results in a simplistic theory that does not do justice to the richness of the available data.
Forestalling a food fight over color
Authors: Dennett Daniel C.
Published: July 2008

The disagreement between “color realists” and “color eliminativists” is better seen as a disagreement over pedagogical policies, about how best to satisfy lay curiosity about “what color is,” than as a clash of substantive theories. To suppose otherwise is to endow the ordinary language term “color” with more authority than it can bear.
Tidying up sensory stores with supraordinate representations
Authors: Barceló Francisco , Periáñez José A. , Gomila Antoni
Published: July 2008

In attempting to integrate the authors' proposed model with results from analogous human event-related potential (ERP) research, we found difficulties with: (1) its apparent disregard for supraordinate representations at posterior multimodal association cortices, (2) its failure to address contextual task effects, and (3) its strict architectural dichotomy between memory storage and control functions.
Physicalism without unknowable colors
Authors: Ross Peter W.
Published: July 2008

Byrne & Hilbert (2003; henceforth B&H) do not adequately explain how it is that phenomenal colors are physical colors, as their physicalism claims. This explanation requires more characterization of the relationship between the epistemology and nature of color than B&H provide. With this characterization, we can see that a physicalist need not accept unknowable color facts, as B&H do.
Language evolution without evolution
Authors: Bickerton Derek
Published: July 2008

Jackendoff's major syntactic exemplar is deeply unrepresentative of most syntactic relations and operations. His treatment of language evolution is vulnerable to Occam's Razor, hypothesizing stages of dubious independence and unexplained adaptiveness, and effectively divorcing the evolution of language from other aspects of human evolution. In particular, it ignores connections between language and the massive discontinuities in human cognitive evolution.
Varieties of procedural accounts of working memory retention systems
Authors: Cowan Nelson
Published: July 2008

The present commentary agrees with many of the points made by Ruchkin et al., but brings up several important differences in assumptions. These assumptions have to do with the nature of the capacity limit in working memory and the possible bases of working-memory activation.
The right kind of content for a physicalist about color
Authors: Skokowski Paul
Published: July 2008

Color experiences have representational content. But this content need not include a propositional component, particularly for reflectance physicalists such as Byrne & Hilbert (B&H). Insisting on such content gives primacy to language where it is not required, and makes the extension of the argument to nonhuman animals suspect.
Why behavior should matter to linguists
Authors: Catania A. Charles
Published: July 2008

Jackendoff's Foundations of Language: Brain, Meaning, Grammar, Evolution has many points of similarity with Skinner's analysis of verbal behavior, though the former emphasizes structure whereas the latter emphasizes function. The parallels are explored in the context of a selectionist account of behavior in general and of verbal behavior in particular. Part of the argument is that behavior drives evolution and therefore also drives brain organization. Another concerns itself with the nature of explanation. Recent experimental developments in behavior analysis are reviewed as potential contributions to an understanding of language that incorporates its functional as well as structural dimensions.
Some mechanisms of working memory may not be evident in the human EEG
Authors: Düzel Emrah
Published: July 2008

Ruchkin et al. use brain-activity data from healthy subjects to assess the physiological validity of a cognitive working memory model and to propose modifications. The conclusions drawn from this data are interesting and plausible, but they have limitations. Much of what is known about the neural mechanisms of working memory comes from single neuron recordings in animals, and it is currently not fully understood how these translate to scalp recordings of EEG.
Color realism revisited
Authors: Byrne Alex , Hilbert David R.
Published: July 2008

Our reply is in four parts. The first part, R1, addresses objections to our claim that there might be “unknowable” color facts. The second part, R2, discusses the use we make of opponent process theory. The third part, R3, examines the question of whether colors are causes. The fourth part, R4, takes up some issues concerning the content of visual experience.
Missing the syntactic piece
Authors: Friederici Angela D. , Bornkessel Ina
Published: July 2008

The notion that the working-memory system is not to be located in the prefrontal cortex, but rather constituted by the interplay between temporal and frontal areas, is of some attraction. However, at least for the domain of sentence comprehension, this perspective is promoted on the basis of sparse data. For this domain, the authors not only missed out on the chance to systematically integrate event-related brain potential (ERP) and neuroimaging data when interpreting their own findings on semantic aspects of working memory, but also neglected syntactic aspects of working memory and computation altogether.
Generative grammar with a human face?
Authors: Edelman Shimon
Published: July 2008

The theoretical debate in linguistics during the past half-century bears an uncanny parallel to the politics of the (now defunct) Communist Bloc. The parallels are not so much in the revolutionary nature of Chomsky's ideas as in the Bolshevik manner of his takeover of linguistics (Koerner 1994) and in the Trotskyist (“permanent revolution”) flavor of the subsequent development of the doctrine of Transformational Generative Grammar (TGG) (Townsend & Bever 2001, pp. 37–40). By those standards, Jackendoff is quite a party faithful (a Khrushchev or a Dubcek, rather than a Solzhenitsyn or a Sakharov) who questions some of the components of the dogma, yet stops far short of repudiating it.
More than working memory rides on long-term memory
Authors: Fuster Joaquín M.
Published: July 2008

Single-unit data from the cortex of monkeys performing working-memory tasks support the main point of the target article. Those data, however, also indicate that the activation of long-term memory is essential to the processing of all cognitive functions. The activation of cortical long-term memory networks is a key neural mechanism in attention (working memory is a form thereof), perception, memory acquisition and retrieval, intelligence, and language.
Complexity underestimated?
Authors: Érdi Péter
Published: July 2008

Instead of commenting directly on Foundations of Language: Brain, Meaning, Grammar, Evolution, I provide some remarks from an interdisciplinary view. Language theory is examined from the perspective of the theory of complex systems. The gestural-vocal dichotomy, network theory, evolutionary mechanisms/algorithms, chaos theory, and constructive approach are briefly mentioned.
From working memory to long-term memory and back: Linked but distinct
Authors: Grossberg Stephen
Published: July 2008

Neural models have proposed how short-term memory (STM) storage in working memory and long-term memory (LTM) storage and recall are linked and interact, but are realized by different mechanisms that obey different laws. The authors' data can be understood in the light of these models, which suggest that the authors may have gone too far in obscuring the differences between these processes.
Imaginary mistakes versus real problems in generative grammar
Authors: Freidin Robert
Published: July 2008

Jackendoff claims that current theories of generative grammar commit a “scientific mistake” by assuming that syntax is the sole source of linguistic organization (“syntactocentrism”). The claim is false, and furthermore, Jackendoff's solution to the alleged problem, the parallel architecture, creates a real problem that exists in no other theory of generative grammar.
Another artificial division – and the data don't support it
Authors: Heil Martin , Rösler Frank , Rolke Bettina
Published: July 2008

Evidence for the contribution of the neocortex to memory is overwhelming. However, the theory proposed by Ruchkin et al. does not only ignore subcortical contributions, but also introduces an unnecessary and empirically unsupported division between the posterior cortex, assumed to represent information, and the prefrontal cortex, assumed to control activation. We argue instead that the representational power of the neocortex is not restricted to its posterior part.
Where is the lexicon?
Authors: Gervain Judit
Published: July 2008

In an attempt to provide a unified model of language-related mental processes, Jackendoff puts forward significant modifications to the generative architecture of the language faculty. While sympathetic to the overall objective of the book, my review points out that one aspect of the proposal – the status of the lexicon – lacks sufficient empirical support.
Language shares neural prerequisites with non-verbal capacities
Authors: Goldenberg Georg
Published: July 2008

Based on neuropsychological evidence of nonverbal impairment accompanying aphasia, I propose that the neural prerequisites for language acquisition are shared with a range of nonverbal capacities. Their commonality concerns the ability to recognize a limited number of finite elements in manifold perceptual entities and to combine them for constructing manifold entities.
Jackendoff's conceptualism
Authors: Higginbotham James
Published: July 2008

In this commentary, I concentrate upon Ray Jackendoff's view of the proper foundations for semantics within the context of generative grammar. Jackendoff (2002) favors a form of internalism that he calls “conceptualism.” I argue that a retreat from realism to conceptualism is not only unwarranted, but even self-defeating, in that the issues that prompt his view will inevitably reappear if the latter is adopted.
Four challenges for cognitive neuroscience and the cortico-hippocampal division of memory
Authors: Howard Harry
Published: July 2008

Jackendoff's criticisms of the current state of theorization in cognitive neuroscience are defused by recent work on the computational complementarity of the hippocampus and neocortex. Such considerations lead to a grounding of Jackendoff's processing model in the complementary methods of pattern analysis effected by independent component analysis (ICA) and principle component analysis (PCA).
Activation of long-term memory by alpha oscillations in a working-memory task?
Authors: Klimesch Wolfgang , Schack Bärbel
Published: July 2008

We focus on the functional specificity of theta and alpha oscillations and show that theta is related to working memory, whereas alpha is related to semantic long-term memory. Recent studies, however, indicate that alpha oscillations also play an important role during short-term memory retention and retrieval. This latter finding provides support for the basic hypothesis suggested by Ruchkin et al.
Retention systems of the brain: Evidence from neuropsychological patients
Authors: Knowlton Barbara J. , Viskontas Indre V.
Published: July 2008

Studies of neuropsychological patients are relevant to models of how long-term memories are stored. If amnesia is considered a binding deficit and not a difficulty in transferring information from short-term to long-term memory, it is unclear why context-free semantic learning is impaired. Also the model should account for the reverse temporal gradient seen in patients with semantic dementia.
Delegation, subdivision, and modularity: How rich is Conceptual Structure?
Authors: Justo Damián , Dutant Julien , Hardy-Vallée Benoît , Nicolas David , Sylvand Benjamin Q.
Published: July 2008

Contra Jackendoff, we argue that within the parallel architecture framework, the generality of language does not require a rich conceptual structure. To show this, we put forward a delegation model of specialization. We find Jackendoff's alternative, the subdivision model, insufficiently supported. In particular, the computational consequences of his representational notion of modularity need to be clarified.
Long-term memories, features, and novelty
Authors: Kroger James K.
Published: July 2008

Ruchkin et al. make a strong claim about the neural substrates of active information. Some qualifications on that conclusion are: (1) Long-term memories and neural substrates activated for perception of information are not the same thing; (2) humans are capable of retaining novel information in working memory, which is not long-term memory; (3) the content of working memory, a dynamically bound representation, is a quantity above and beyond the long-term memories activated, or the activity in perceptual substrates.
Neuropsychological evidence for the distinction between grammatically relevant and irrelevant components of meaning
Authors: Kemmerer David
Published: July 2008

Jackendoff (2002) argues that grammatically relevant and irrelevant components of meaning do not occupy distinct levels of the semantic system. However, neuropsychological studies have found that the two components doubly dissociate in brain-damaged subjects, suggesting that they are in fact segregated. Neural regionalization of these multidimensional semantic subsystems might take place during language development.
A mixed treatment of categoricity and regularity: Solutions that don't do justice to a well-exposed complexity
Authors: Lavie René Joseph
Published: July 2008

Jackendoff's position with respect to categories (for lexical items and larger constituents) is unclear. Positing categories is (1) implausible in several respects; (2) it makes the binding problem in language seem more massive than it actually is; and (3) it makes it difficult to explain language acquisition. Waiting for connectionism to fulfill its promise, a different track is sketched which is residually symbolic, exemplarist, and analogy-based.
Does sustained ERP activity in posterior lexico-semantic processing areas during short-term memory tasks only reflect activated long-term memory?
Authors: Majerus Steve , Van der Linden Martial , Collette Fabienne , Salmon Eric
Published: July 2008

We challenge Ruchkin et al.'s claim in reducing short-term memory (STM) to the active part of long-term memory (LTM), by showing that their data cannot rule out the possibility that activation of posterior brain regions could also reflect the contribution of a verbal STM buffer.
“Parallel architecture” as a variety of stratificationalism
Authors: Lockwood David G.
Published: July 2008

The model of parallel architecture for language presented by Jackendoff is a kind of stratificational model in the spirit of Sydney Lamb. It differs from the more usual stratificationalism most importantly in its clear commitment to nativism, though the variety of nativism is greatly modified from what is more usual among Chomskyans. The revised model presents a potential for fruitful discussion with proponents of stratificationalism, and the potential for enrichment via a relational implementation.
Cognitive neuropsychological evidence for common processes underlying generation and storage of language representations
Authors: Martin Nadine
Published: July 2008

Ruchkin et al. offer a compelling case for a model of short-term storage without a separate buffer. Here, I discuss some cognitive neuropsychological data that have been offered in support of and against their model. Additionally, I discuss briefly some new directions in cognitive neuropsychological research that bear on the role of attention in Ruchkin et al.'s model.
Cartesian and empirical linguistics: The growing gulf
Authors: MacAogáin Eoghan
Published: July 2008

Jackendoff's Foundations of Language: Brain, Meaning, Grammar, Evolution (2002) achieves a major shift in the focus and methods of Generative Linguistics (GL). Yet some of the original restrictive features of GL, cognitivism and Cartesianism in particular, remain intact in the new work and take on a more extreme form with the addition of a phenomenalist ontology.
Grammar and brain
Authors: Schnelle Helmut
Published: July 2008

Jackendoff's account of relating linguistic structure and brain structure is too restricted in concentrating on formal features of computational requirements, neglecting the achievements of various types of neuroscientific modelling. My own approaches to neuronal models of syntactic organization show how these requirements could be met. The book's lack of discussion of a sound philosophy of the relation is briefly mentioned.
Rescuing generative linguistics: Too little, too late?
Authors: Spivey Michael J. , Gonzalez-Marquez Monica
Published: July 2008

Jackendoff's Foundations of Language: Brain, Meaning, Grammar, Evolution attempts to reconnect generative linguistics to the rest of cognitive science. However, by minimally acknowledging decades of work in cognitive linguistics, treating dynamical systems approaches somewhat dismissively, and clinging to certain fundamental dogma while revising others, he clearly risks satisfying no one by almost pleasing everyone.
How does the attentional pointer work in prefrontal cortex?
Authors: Osaka Naoyuki
Published: July 2008

The current model, based on event-related potential (ERP) studies, posits that the working-memory system is a state of activated long-term memory; this appears comprehensive, but it needs further detailed analysis of functional neural connectivity analysis within the prefrontal cortex (PFC) and between the posterior and prefrontal cortex. Specifically, the role of dorsolateral PFC and anterior cingulate cortex (ACC) is probably critical for PFC's attentional controller. Neural implementation of the executive function in working memory appears critical to build a firm model.
From Frege to dynamic theories of meaning
Authors: ter Meulen Alice G. B.
Published: July 2008

In designing stratified models of human language, understanding notions of logical consequence and validity of inference require separating the aspects of meaning that vary between models from logical constants. Modelling meaning requires choices regarding the primitives, where the Fregean program is still offering us the fundamental insights on the role of truth, judgement, and grasping or sharing of thoughts.
The architecture is not exactly parallel: Some modules are more equal than others
Authors: Velichkovsky Boris B. , Kibrik Andrej A. , Velichkovsky Boris M.
Published: July 2008

Despite its computational elegancy, Jackendoff's proposal to reconcile competing approaches by postulating a parallel architecture for phonological, syntactic, and semantic modules is disappointing. We argue that it is a pragmatic version of the leading module which Jackendoff would probably prefer, but which he does not explicitly acknowledge. This internal conflict leads to several shortcomings and even distortions of information presented in the book.
The short-term dynamics within a network of connections is creative
Authors: Phillips William A.
Published: July 2008

Although visual long-term memory (VLTM) and visual short-term memory (VSTM) can be distinguished from each other (and from visual sensory storage [SS]), they are embodied within the same modality-specific brain regions, but in very different ways: VLTM as patterns of connectivity and VSTM as patterns of activity. Perception and VSTM do not “activate” VLTM. They use VLTM to create novel patterns of activity relevant to novel circumstances.
Models versus descriptions: Real differences and language differences
Authors: Raaijmakers Jeroen G. W. , Shiffrin Richard M.
Published: July 2008

We argue that an approach that treats short-term memory as activated long-term memory is not inherently in conflict with information recycling in a limited-capacity or working-memory store, or with long-term storage based on the processing in such a store. Language differences aside, real model differences can only be assessed when the contrasting models are formulated precisely.
How did we get from there to here in the evolution of language?
Authors: Zuidema Willem , de Boer Bart
Published: July 2008

Jackendoff's scenario of the evolution of language is a major contribution towards a more rigorous theory of the origins of language, because it is theoretically constrained by a testable theory of modern language. However, the theoretical constraints from evolutionary theory are not really recognized in his work. We hope that Jackendoff's lead will be followed by intensive cooperation between linguistic theorists and evolutionary modellers.
Double dissociation in the effects of brain damage on working memory
Authors: Verleger Rolf
Published: July 2008

As revealed by standard neuropsychological testing, patients with damage either to the frontal lobe or to the hippocampus suffer from distinct impairments of working memory. It is unclear how Ruchkin et al.'s model integrates the role played by the hippocampus.
Neuronal synchronization accompanying memory processing
Authors: Weiss Sabine , Mueller Horst M.
Published: July 2008

In their target article, Ruchkin et al. propose sustained neuronal interaction of prefrontal and posterior cortex involved in memory-storage mechanisms with respect to electrophysiological findings on the relationship of short-term and long-term memory processes. We will evaluate this claim in light of recent evidence from our laboratory on EEG coherence analysis of memory processes accompanying language comprehension.
The signal functions of early infant crying
Authors: Soltis Joseph
Published: July 2008

In this article I evaluate recent attempts to illuminate the human infant cry from an evolutionary perspective. Infants are born into an uncertain parenting environment, which can range from indulgent care of offspring to infanticide. Infant cries are in large part adaptations that maintain proximity to and elicit care from caregivers. Although there is not strong evidence for acoustically distinct cry types, infant cries may function as a graded signal. During pain-induced autonomic nervous system arousal, for example, neural input to the vocal cords increases cry pitch. Caregivers may use this acoustic information, together with other cues, to guide caregiving behavior. Serious pathology, on the other hand, results in chronically and severely abnormal cry acoustics. Such abnormal crying may be a proximate cause of adaptive infant maltreatment, in circumstances in which parents cut their losses and reduce or withdraw investment from infants with low survival chances. An increase in the amount of crying during the first few months of life is a human universal, and excessive crying, or colic, represents the upper end of this normal increase. Potential signal functions of excessive crying include manipulation of parents to acquire additional resources, honest signaling of need, and honest signaling of vigor. Current evidence does not strongly support any one of these hypotheses, but the evidence is most consistent with the hypothesis that excessive early infant crying is a signal of vigor that evolved to reduce the risk of a reduction or withdrawal of parental care.
Complexity is a cue to the mind
Authors: Kampis George
Published: July 2008

The relevance of chaotic itinerancy and other types of exotic dynamical behavior described by Tsuda (2001) certainly goes beyond the scope of his target article. These concepts of dynamics may offer a general framework for the understanding of complexity, which could help to restructure the analysis and conceptualization of mental states in novel ways, providing insights for the philosophy of mind.
Good hunters keep smaller shares of larger pies
Authors: Alvard Michael
Published: July 2008

High producers are motivated to hunt in spite of high levels of sharing because the transfers come from absolutely larger amounts of resource. In the context of a generalized cooperative subsistence strategy, stinginess could provoke the withdrawal of cooperative partners and result in a loss of income. Good producers could have more to lose by not sharing than poor producers would.
Chaotic itinerancy is a key to mental diversity
Authors: Tsuda Ichiro
Published: July 2008

Kampis proposes the study of chaotic itinerancy, pointing out its significance in domains of cognitive science and philosophy. He has discovered in the concept of chaotic itinerancy the possibility for a new dynamical approach that elucidates mental states with a physical basis. This approach may therefore provide the means to go beyond the connectionist approach. In accordance with his theory, I here highlight three issues regarding chaotic itinerancy: transitory dynamics, diversity, and self-modifying system.
Mothering plus vocalization doesn't equal language
Authors: Bickerton Derek
Published: July 2008

Falk has much of interest to say on the evolution of mothering, but she fails to address the core issue of language evolution: how symbolism or structure evolved. Control of infants does not require either, and Falk provides neither evidence nor arguments supporting referential symbolism as a component of mother-infant interactions.
Where's the beef? It's less about cooperation, more about conflict
Authors: Betzig Laura
Published: July 2008

Individuals give for two reasons. One is to get a benefit back. The other is to avoid a cost. “Cooperation” theories stress mutual benefits. “Conflict” theories stress costs. Hunters may give up part of their hunt because they get favors back, or because the recipients are stronger than they are and the hunting isn't as good anywhere else.
Tolerated scrounging in nonhuman primates
Authors: Brown Gillian R.
Published: July 2008

Gurven suggests that the tolerated scrounging model has limited relevance for explaining patterns of food transfers in human populations. However, this conclusion is based on a restricted interpretation of the tolerated scrounging model proposed originally by Blurton Jones (1987). Examples of food transfers in nonhuman primates illustrate that the assumptions of Gurven's tolerated scrounging model are open to question.
Spatial inference: No difference between mental images and mental models
Authors: Knauff Markus , Schlieder Christoph
Published: July 2008

In contrast to Pylyshyn's view, there is no such thing as “reasoning in general.” Different types of reasoning tasks are solved with different reasoning strategies. A more specific null hypothesis is that spatial inference with mental images involves the same representational formalism as that of spatial inference with mental models. There is no evidence that this hypothesis must be rejected.
Key variables in tests of food sharing
Authors: Franzen Margaret
Published: July 2008

Gurven discusses three key features of food sharing, specifically producer control, need, and contingency. I make two general points regarding the use of these variables in tests of food-sharing hypotheses. First, that these variables are relative, not absolute concepts; and second, that the predictions generated from these variables overlap significantly. In addition, I suggest frequency of sharing as a measure of contingency for the RA hypothesis.
Infant crying in hunter-gatherer cultures
Authors: Fouts Hillary N. , Lamb Michael E. , Hewlett Barry S.
Published: July 2008

By synthesizing evolutionary, attachment, and acoustic perspectives, Soltis has provided an innovative model of infant cry acoustics and parental responsiveness. We question some of his hypotheses, however, because of the limited extant data on infant crying among hunter-gatherers. We also question Soltis' distinction between manipulative and honest signaling based upon recent contributions from attachment theory.
Bipedalism, canine tooth reduction, and obligatory tool use
Authors: Brace C. Loring
Published: July 2008

Bipedalism in the earliest hominid specimens is always accompanied by the reduction of projecting canine teeth. Body size is smaller than chimpanzees or humans, but molar teeth are markedly larger. Use of a pointed stick for defensive purposes on the one hand, and digging for USOs on the other, may be why bipedalism was selected for. Passing such learned behavior to the next generation may have played a role in selecting for language.
A kind man benefits himself – but how? Evolutionary models of human food sharing
Authors: Getty Thomas
Published: July 2008

Can evolutionary models explain food sharing in traditional human societies? Gurven's analysis cannot rule out any of the models (kin selection, reciprocal altruism, tolerated scrounging, costly signaling, or by-product mutualism), and quantitative partitioning of relative importance is not feasible. For now, the hypotheses seem like the proverbial blind men examining the elephant: each was partly in the right, and all were in the wrong!
Autism and schizophrenia: Similar perceptual consequence, different neurobiological etiology?
Authors: Bertone Armando , Mottron Laurent , Faubert Jocelyn
Published: July 2008

Phillips & Silverstein (P&S, 2003) propose that NMDA-receptor dysfunction may be the fundamental neurobiological mechanism underlying and associating impaired holistic perception and cognitive coordination with schizophrenic psychopathology. We discuss how the P&S hypothesis shares different aspects of the weak central coherence account of autism from both theoretical and experimental perspectives. Specifically, we believe that neither those persons with autism nor those with schizophrenia integrate visuo-perceptual information efficiently, resulting in incongruous internal representations of their external world. However, although NMDA-hypofunction may be responsible for perceptual impairments in schizophrenia and possibly autism, we suggest that it is highly unlikely that NMDA-hypofunction is specifically responsible for the autistic behavioral symptomology, as described by P&S in their target article.
A common link between aging, schizophrenia, and autism?
Authors: Faubert Jocelyn , Bertone Armando
Published: July 2008

Phillips & Silverstein (P&S, 2003) have proposed that NMDA-receptor hypofunction is the central reason for impaired cognitive coordination and abnormal gestalt-like perceptual processing in schizophrenia. We suggest that this model may also be applicable to non-pathological (or normal) aging given the compelling evidence of NMDA-receptor involvement during the aging process that results in age-related change in higher-level perceptual performance. Given that such deficits are present in other neurological disorders such as autism, an argument for a systematic assessment of perceptual functioning in these conditions may be posited.
Sleep-wake processes play a key role in early infant crying
Authors: Jenni Oskar G.
Published: July 2008

The crying curve across early infancy may reflect the developing interaction between circadian and homeostatic processes of sleep-wake regulation. Excessive crying may be interpreted as a misalignment of the two processes. On the basis of the proposed mechanism, excessive crying may be an honest signal of need, namely, to elicit parental resources to modulate the behavioral state.
On sharing a pie: Modeling costly prosocial behavior
Authors: Lefebvre Vladimir A.
Published: July 2008

In this comment, I describe how the processes of free giving can be simulated with the help of the Reflexive Intentional Model of the Subject (RIMS). This simulation demonstrates that there are two essential factors affecting the size of a share given to others: limits accepted by the society as “normal,” and the individual's subjective estimation of a mean share donated by other members of the society.
