TRANSFER OF STIMULUS CONTROL FROM MOTOR TO VERBAL STIMULI1

A transfer of stimulus control procedure was used to teach three profoundly retarded adolescents a series of specific responses to specific verbal instructions. After imitative control of a behavior was established, a verbal instruction was presented immediately before the behavior was modelled. Each correct response was followed on the next trial by inserting a delay between the verbal instruction and the modelling of the behavior. The delays increased from trial to trial. Transfer of stimulus control was indicated when a subject responded correctly on five consecutive trials before the behavior was modelled. All three subjects responded correctly to each verbal instruction after that item was trained in a multiple-baseline order. Generalization did not occur to items that had not been trained. Probe data revealed that some variations of the verbal instructions controlled responses after training was completed.

Anxious personality and functional efficiency of the insular-opercular network: A graph-analytic approach to resting-state fMRI

The brain is an intricate network, not only structurally but also functionally. On the functional level, connectivity in the brain is organized in separable yet interacting networks that support information processing by maintaining a ready state, even in the absence of external stimulation. It has been hypothesized that an insular-opercular network underlies the processing of emotionally salient information and that individual differences in functional connectivity within this network correspond to individual differences in trait anxiety. Here, we tested this relationship by applying graph analysis to multiple regions of interests delineating the insular-opercular network to estimate the characteristic path length that quantifies the overall information exchange efficiency within a given network. We found that people scoring high on the anxiety-related temperament-dimension harm avoidance had decreased insular-opercular network efficiency in the resting state, as indicated by a higher characteristic path length. Furthermore, people scoring high on harm avoidance showed generally reduced functional connectivity between brain regions; the relationship between harm avoidance and insular-opercular network efficiency remained significant when controlling for mean connectivity within this network. No such results were found for other resting-state networks. The results provide insights into how personality is organized in the human brain and point toward clinically relevant endophenotypes for affective and mood disorders.     

Fine motor skills enhance lexical processing of embodied vocabulary: A test of the nimble-hands,nimble-minds hypothesis

Research suggests that fine motor skills (FMS) are linked to aspects of cognitive development in children. Additionally, lexical processing advantages exist for words implying a high body–object interaction (BOI), with initial findings indicating that such words in turn link to children’s FMS—for which we propose and evaluate four competing hypotheses. First, a maturational account argues that any links between FMS and lexical processing should not exist once developmental variables are controlled for. Second, functionalism posits that any link between FMS and lexical processing arises due to environmental interactions. Third, the semantic richness hypothesis argues that sensorimotor input improves lexical processing, but predicts no links between FMS and lexical processing. A fourth account, the nimble-hands, nimble minds (NHNM) hypothesis, proposes that having greater FMS improves lexical processing for high-BOI words. In two experiments, the response latencies of preschool children (n?=?90, n?=?76, ages?=?5;1) to 45 lexical items encompassing high-BOI, low-BOI, and less imageable words were measured, alongside measures of FMS, reasoning, and general receptive/expressive vocabulary. High-BOI words appeared to show unique links to FMS, which remained after accounting for low-BOI and less imageable words, general vocabulary, reasoning, and chronological age. Although further work is needed, the findings provide initial support for the NHNM hypothesis.     

New perspectives on binding in visual working memory

How does visual working memory (WM) store the binding between different features of a visual object (like colour, orientation, and location), and does memorizing these bindings require additional resources beyond memorizing individual features? These questions have traditionally been addressed by comparing performance across different types of change detection task. More recently, experimental tasks such as analogue (cued) recall, combined with analysis methods including Bayesian hypothesis testing and formal model comparison, have shed new light on the properties of WM. A significant new perspective is that noise in neural representation limits the precision of recall, and several recent models incorporate this view to account for failures of binding in WM. We review the literature on feature binding with a focus on these new developments and discuss their implications for the interpretation of classical findings.     

Are country level prevalences of rule violations associated with knowledge overclaiming among students?

Cultural norms of behaviour influence desirable and problematic behaviours of individuals. In particular, cultural norms should influence individuals' dishonesty. In a recent Nature study, prevalence of rule violations was introduced as a new country‐level measure of behavioural norms. However, information on individuals' actual honesty was not available due to characteristics of the experimental design. Overcoming this limitation, we show that country‐level behavioural norms are related to individual‐level knowledge overclaiming behaviour (i.e., claiming to know concepts that do not exist, a measure of individuals' actual behavioural dishonesty) among 290,954 students from 57 countries (from the 2012 PISA study). Our study represents a crucial test of the argument that cultural norms influence individual's behaviour and of the validity of the measurement of countries' prevalences of rule violations. These results imply that shaping the behaviour of today's students may result in new behavioural norms that emphasise honesty and rule adherence more strongly.     

Personal and parents’ life stories in patients with borderline personality disorder

Patients with borderline personality disorder (BPD) display disturbances in understanding self and others. We examined whether these disturbances extended to how patients described their personal and parents’ life stories and to measures of identity, alexithymia, empathy, and emotional intelligence. Thirty BPD patients and 30 matched control participants described personal and parents’ life stories and completed measures of identity disturbance, alexithymia, empathy, and emotional intelligence. Compared to the controls, patients with BPD described their personal and their parents’ life stories more negatively and with fewer themes of agency and communion fulfillment. Patients and controls showed equally complex reasoning about their personal life stories, but patients displayed less complexity and more self‐other confusion, when reasoning about their parents’ stories. Patients also differed from controls on identity disturbance, alexithymia, and empathy. The results suggest that patients’ storied understanding of themselves and others are disturbed and should be taken into account to better understand BPD.
