Published: November 2017

AbstractBackgroundAttention-deficit/hyperactivity disorder (ADHD) is proposed to be a neuropsychologically heterogeneous disorder that encompasses two distinct sub-groups, one with executive function (EF) deficits and one with delay aversion (DA). However, such claims have often been based on studies that have operationalized neuropsychological deficits using a categorical approach – using intuitive but rather arbitrary, clinical cut-offs. The current study applied an alternative empirical approach to sub-grouping in ADHD, latent profile analysis (LPA), and attempted to validate emerging subgroups through clinically relevant correlates.MethodsOne-hundred medication-naïve children with ADHD and 96 typically developing children (6–14 years) completed nine EF and three DA tasks as well as an odor identification test. Parents and teachers provided reports of the children's behavior (ADHD and EF). Models of the latent structure of scores on EF and DA tests were contrasted using confirmatory factor analysis (CFA). LPA was carried out based on factor scores from the CFA and sub-groups were compared in terms of odor identification and behavior.ResultsA model with one DA and two EF factors best fit the data. LPA resulted in four sub-groups that differed in terms of general level of neuropsychological performance (ranging from high to very low), odor identification, and behavior. The sub-groups did not differ in terms of the relative EF and DA performance. Results in the ADHD group were replicated in the control group.ConclusionsWhile EF and DA appear to be dissociable constructs; they do not yield distinct sub-groups when sub-grouping is based on a statistical approach such as LPA.
The architecture challenge: Future artificial-intelligence systems will require sophisticated architectures, and knowledge of the brain might guide their construction
Authors: Baldassarre Gianluca , Santucci Vieri Giuliano , Cartoni Emilio , Caligiore Daniele 
Published: November 2017

AbstractIn this commentary, we highlight a crucial challenge posed by the proposal of Lake et al. to introduce key elements of human cognition into deep neural networks and future artificial-intelligence systems: the need to design effective sophisticated architectures. We propose that looking at the brain is an important means of facing this great challenge.
Building on prior knowledge without building it in
Authors: Hansen Steven S. , Lampinen Andrew K. , Suri Gaurav , McClelland James L. 
Published: November 2017

AbstractLake et al. propose that people rely on “start-up software,” “causal models,” and “intuitive theories” built using compositional representations to learn new tasks more efficiently than some deep neural network models. We highlight the many drawbacks of a commitment to compositional representations and describe our continuing effort to explore how the ability to build on prior knowledge and to learn new tasks efficiently could arise through learning in deep neural networks.
Social-motor experience and perception-action learning bring efficiency to machines
Authors: Marin Ludovic , Mostafaoui Ghiles 
Published: November 2017

AbstractLake et al. proposed a way to build machines that learn as fast as people do. This can be possible only if machines follow the human processes: the perception-action loop. People perceive and act to understand new objects or to promote specific behavior to their partners. In return, the object/person provides information that induces another reaction, and so on.
Avoiding frostbite: It helps to learn from others
Authors: Tessler Michael Henry , Goodman Noah D. , Frank Michael C. 
Published: November 2017

AbstractMachines that learn and think like people must be able to learn from others. Social learning speeds up the learning process and – in combination with language – is a gateway to abstract and unobservable information. Social learning also facilitates the accumulation of knowledge across generations, helping people and artificial intelligences learn things that no individual could learn in a lifetime.
Microscopic and macroscopic approaches to the mental representations of second languages
Authors: Cai Zhenguang G. , Liu Haitao 
Published: November 2017

AbstractWith a particular reference to second language (L2), we discuss (1) how structural priming can be used to tap into L2 representations and their relationships with first and target language representations; and (2) how complex networks additionally can be used to reveal the global and local patterning of L2 linguistic features and L2 developmental trajectories.
Moving beyond the priming of single-language sentences: A proposal for a comprehensive model to account for linguistic representation in bilinguals
Authors: Kootstra Gerrit Jan , Rossi Eleonora 
Published: November 2017

AbstractIn their target article, Branigan & Pickering (B&P) briefly discuss bilingual language representation, focusing primarily on cross-language priming between single-language sentences. We follow up on this discussion by showing how structural priming drives real-life phenomena of bilingual language use beyond the priming of unilingual sentences and by arguing that B&P's account should be extended with a representation for language membership.
On the nature of structure in structural priming
Authors: Kwon Nayoung , Lee Yoonhyoung 
Published: November 2017

AbstractLike Branigan & Pickering (B&P), we agree that processing evidence is important for linguistic theorization; however, without much evidence of priming of hierarchical argument structure independent of linear ordering, the nature of “structure” in structural priming remains unclear. Consequently, it is an empirical question whether structural priming and acceptability judgments tap into cognitive processes of a similar nature.
Priming methods in semantics and pragmatics
Authors: Maldonado Mora , Spector Benjamin , Chemla Emmanuel 
Published: November 2017

AbstractStructural priming is a powerful method to inform linguistic theories. We argue that this method extends nicely beyond syntax to theories of meaning. Priming, however, should still be seen as only one of the tools available for linguistic data collection. Specifically, because priming can occur at different, potentially conflicting levels, it cannot detect every aspect of linguistic representations.
Can structural priming answer the important questions about language?
Authors: Martin Andrea E. , Huettig Falk , Nieuwland Mante S. 
Published: November 2017

AbstractStructural priming makes a valuable contribution to psycholinguistics, but it taps into implicit memory representations and processes that may differ from what is deployed during online language processing. As a result, the strength of inductive inference regarding linguistic representation is rather limited. We question whether implicit memory for language can and should be equated with linguistic representation or with language processing.
The syntax of priming
Authors: O'Grady William 
Published: November 2017

AbstractPriming reflects the reactivation of processing routines that map strings of words onto semantic representations (and vice versa) without the mediation of syntactic structure, including the “flat structure” that Branigan & Pickering (B&P) propose. Key evidence for this claim comes from the possibility of priming relations involving subject-verb sequences, which are not syntactic constituents.
Developmental psycholinguistics teaches us that we need multi-method, not single-method, approaches to the study of linguistic representation
Authors: Rowland Caroline F. , Monaghan Padraic 
Published: November 2017

AbstractIn developmental psycholinguistics, we have, for many years, been generating and testing theories that propose both descriptions of adult representations and explanations of how those representations develop. We have learnt that restricting ourselves to any one methodology yields only incomplete data about the nature of linguistic representations. We argue that we need a multi-method approach to the study of representation.
Structural priming and the representation of language
Authors: Branigan Holly P. , Pickering Martin J. 
Published: November 2017

AbstractStructural priming offers a powerful method for experimentally investigating the mental representation of linguistic structure. We clarify the nature of our proposal, justify the versatility of priming, consider alternative approaches, and discuss how our specific account can be extended to new questions as part of an interdisciplinary programme integrating linguistics and psychology as part of the cognitive sciences of language.
The roles of word-form frequency and phonological neighbourhood density in the acquisition of Lithuanian noun morphology
Authors: SAVIČIŪTĖ Eglė , AMBRIDGE Ben , PINE Julian M. 
Published: November 2017

AbstractFour- and five-year-old children took part in an elicited familiar and novel Lithuanian noun production task to test predictions of input-based accounts of the acquisition of inflectional morphology. Two major findings emerged. First, as predicted by input-based accounts, correct production rates were correlated with the input frequency of the target form, and with the phonological neighbourhood density of the noun. Second, the error patterns were not compatible with the systematic substitution of target forms by either (a) the most frequent form of that noun or (b) a single morphosyntactic default form, as might be predicted by naive versions of a constructivist and generativist account, respectively. Rather, most errors reflected near-miss substitutions of singular for plural, masculine for feminine, or nominative/accusative for a less frequent case. Together, these findings provide support for an input-based approach to morphological acquisition, but are not adequately explained by any single account in its current form.

Published: November 2017

AbstractViolence exposure during childhood is common and associated with poor cognitive and academic functioning. However, little is known about how violence exposure influences cognitive processes that might contribute to these disparities, such as working memory, or their neural underpinnings, particularly for cognitive processes that occur in emotionally salient contexts. We address this gap in a sample of 54 participants aged 8 to 19 years (50% female), half with exposure to interpersonal violence. Participants completed a delayed match to sample task for emotional faces while undergoing functional magnetic resonance imaging scanning. Violence-exposed youth performed worse than controls on happy and neutral, but not angry, trials. In whole-brain analysis, violence-exposed youth had reduced activation in the left middle frontal gyrus and right intraparietal sulcus during encoding and the left superior temporal sulcus and temporal–parietal junction during retrieval compared to control youth. Reduced activation in the left middle frontal gyrus during encoding and the left superior temporal sulcus during retrieval mediated the association between violence exposure and task performance. Violence exposure influences the frontoparietal network that supports working memory as well as regions involved in facial processing during working memory for emotional stimuli. Reduced neural recruitment in these regions may explain atypical patterns of cognitive processing seen among violence-exposed youth, particularly within emotional contexts.
Maternal smoking during pregnancy and offspring executive function: What do we know and what are the next steps?
Authors: Micalizzi Lauren , Knopik Valerie S. 
Published: November 2017

AbstractChildren exposed to maternal smoking during pregnancy (MSDP) exhibit difficulties in executive function (EF) from infancy through adolescence. Due to the developmental significance of EF as a predictor of adaptive functioning throughout the life span, the MSDP–EF relation has clear public health implications. In this paper, we provide a comprehensive review of the literature on the relationship between MSDP and offspring EF across development; consider brain-based assessments, animal models, and genetically informed studies in an effort to elucidate plausible pathways of effects; discuss implications for prevention and intervention; and make calls to action for future research.
The final straw? An overview of Straw-headed Bulbul Pycnonotus zeylanicus trade in Indonesia
Authors: BERGIN DANIEL , CHNG SERENE C. L. , EATON JAMES A. , SHEPHERD CHRIS R. 
Published: November 2017

SummaryCurrently listed as Endangered on the IUCN Red List of Threatened Species, the Straw-headed Bulbul Pycnonotus zeylanicus is being driven towards extinction throughout most of its range by unregulated illegal trade supplying the demand for songbirds. We conducted surveys of bird markets in North and West Kalimantan, and Central, West and East Java between July 2014 and June 2015, and observed a total of 71 Straw-headed Bulbuls in 11 markets in eight cities. Comparing our data with the literature, we found that as numbers in markets are decreasing, prices are increasing to over 20 times the prices recorded in 1987, indicating that numbers in the wild are diminishing. This is corroborated by widespread extirpations throughout their range and reports from traders that Straw-headed Bulbuls are increasingly difficult to locate, while demand from consumers remains high. Concerted efforts from a variety of stakeholders are urgently needed to prevent the extinction of this species in the wild. We recommend that the Straw-headed Bulbul be included in Indonesia’s list of protected species, considered for uplisting to Critically Endangered on the IUCN Red List and listed in Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). We also urge the Indonesian Government to effectively enforce existing laws, targeting the open bird markets to shut down the trade in this and other threatened species.
The Chimes of Freedom: Bob Dylan, Epigrammatic Validity, and Alternative Facts
Authors: HARRIS JOHN 
Published: November 2017

Abstract:This essay brings together work I have done over the past 10 years: on the nature of ethics, on the purpose of ethics, and on its foundations in a way that, I hope, as E.M. Forster put it, connects “the prose and the passion.” I deploy lessons learned in this process to identify and face what I believe to be crucial challenges to science and to freedom (as defended by, among others, Cicero, Pete Seeger, Bob Dylan, Thomas Hobbes, John Stuart Mill, and Bertrand Russell). Finally I consider threats to freedom of a different sort, posed by the creation and dissemination of “alternative facts” and by what is sometimes called “super” or “full” artificial intelligence (AI).

AbstractObjectiveEven though current policy is strongly focused on the crucial first ‘1000 days’, it might be still possible to enhance cognitive function during the pre-adolescent and adolescent years by improving micronutrient status. In Cambodia, nutritional status is poor. Provision of rice fortified with micronutrients through a school meal programme (SMP) could be a cost-effective strategy to help improve health and school performance. The present study aimed to evaluate the effect of three different micronutrient-fortified rice formulations on cognitive function in Cambodian children.SettingSixteen Cambodian schools receiving SMP.DesignThe FORISCA-UltraRice®+NutriRice®study was a randomized, double-blind, placebo-controlled trial. Four groups of four schools were randomly allocated to receive normal rice, UltraRice®Original, UltraRice®New or NutriRice®. Within each school, 132 children were randomly selected. Data on cognitive performance (picture completion, block design and Raven’s coloured progressive matrices (RCPM)), anthropometry, parasite infestation and micronutrient status were collected before the intervention and after 6 months.SubjectsCognitive data were available for 1796 children aged 6–16 years.ResultsAll cognitive scores improved after 6 months (P<0·001). Block design score improvement was significantly higher in children consuming UltraRice®Original (P=0·03) compared with the other fortified rice groups and placebo. No difference among groups was found on RCPM or picture completion scores. Stunting, parasite infestation and inflammation negatively affected the impact of the intervention.ConclusionsCombined with other interventions, using SMP to distribute fortified rice to schoolchildren may be a cost-effective way to increase cognitive performance and thereby improve school performance and educational achievements.
EMBODIED BLACK RAGE
Authors: Canham Hugo 
Published: November 2017

AbstractExamining two sets of archived materials that include a corpus of narratives that reflect on the period of apartheid in South Africa and posters used by anti-apartheid activists, the paper teases out the operations of racism and the manifestations of rage on the Black body. Critical discourse analysis and affect as theory and method are applied to trace the work of racism and its affective consequences and resistances. Here affect is deployed to read the terrain of the corporeal and the discursive. Black rage is seen as a response to White supremacy and it has the following outcomes: it can have destructive consequences, can enable psychological release of pent up anger, and can simultaneously be an expression of self-love.
Cultivating opportunity: do land transfer tools improve land access for beginning farmers?
Authors: Plotkin Samuel Ethan , Hassanein Neva 
Published: November 2017

AbstractA vast amount of agricultural land in the USA will change hands in the coming years as established farmers age and transition out of farm ownership. As a result, beginning farmers are likely to continue to face numerous obstacles as they try to find and purchase the property. Two of the greatest barriers include the high price that farm property usually commands and the steady conversion of farmland to non-agricultural uses (e.g., suburban development). Non-profit organizations and government agencies have used conservation easements extensively to protect against conversion of agricultural land, but, too often, that does not ensure affordability for beginning farmers. Accordingly, advocates have developed supplemental land transfer tools intended to enhance conservation easements and help beginning farmers gain access to land. In this exploratory research, we look at two of these novel tools, namely Conservation Buyer Programs (CBPs) and the option to purchase at agricultural value (OPAV). Specifically, we present case studies about two entities that use OPAV and two that use CBPs in order to understand how these tools function and whether they improve land access for beginning farmers. Interviews with professionals and beginning farmers who have worked with these tools in four states inform our analysis and add depth to previous scholarship. We found that OPAV and CBPs can improve access to agricultural land for beginning farmers under certain circumstances. These tools, however, are not panaceas to the challenge land affordability presents, nor are they the only tools used by the entities we studied. CBPs alone have rarely been used to help new farmers; yet, they have been paired effectively with a conservation easement and OPAV. Additionally, we found a similar tool, the simultaneous sale, has been quite effective when paired with OPAV, and less costly than the traditional conservation buyer approach. All of these tools expand the land access toolbox in important ways, but given the paucity of existing scholarship on this topic, additional research is needed. Practitioners and researchers must think critically about whether these tools are the most effective instruments to employ in the effort to get beginning farmers on the land.

Published: November 2017

AbstractHerbicide-resistantEchinochloaspp. pose a significant threat to U.S. rice production. Two surveys were conducted to characterizeEchinochloaresistance to common rice herbicides and provide important demographic information on the populations in Arkansas: one was theEchinochloa Herbicide Resistance Confirmation Surveyconducted annually since 2006; the other was theEchinochloa Herbicide Resistance Demographics Surveyconducted since 2010. TheResistance Confirmation Surveyshowed that resistance to propanil (50%) was most prevalent, followed by quinclorac (23%), imazethapyr (13%), and cyhalofop (3%). Multiple resistance increased with time, with 27% of accessions being multiple-resistant, mostly to propanil+quinclorac (12%). The parallelResistance Demographics Surveytested resistance by species. Of the 264 accessions collected, 73% were junglerice, 14% were rough barnyardgrass, and 11% were barnyardgrass. Overall, this survey also showed resistance to propanil (53%) and quinclorac (28%) being most prevalent, with low frequencies of resistance to cyhalofop (12%) and imazethapyr (6%). Resistance to herbicides was less frequent with barnyardgrass (54%) and rough barnyardgrass (28%) than with junglerice (73%). Multiple resistance was most frequent with junglerice (33%) and least frequent with rough barnyardgrass (8%). Across both surveys, the resistance cases were clustered in the northeast and Grand Prairie regions of the state. Herbicide resistance amongEchinochloapopulations in rice fields is continuing to increase in frequency and complexity. This is a consequence of sequential selection with different major herbicide sites of action, starting with propanil followed by quinclorac and others.
