New Word Acquisition in Children: Examining the Contribution of Verbal Short‐term Memory to Lexical and Semantic Levels of Learning

A variety of evidence suggests that human vocabulary acquisition and verbal short‐term ability are related. The aim of this study was to investigate the learning of new lexical and semantic representation in 7 to 12 years old children selected on the basis of their poor working memory capacity. A deep characterization of the short‐term memory (STM) capacities has been carried out through a series of tasks derived from recent STM models tapping STM, language and attentional processes. Participants experienced a three conditions word learning task designed to reflect lexical learning, semantic learning and lexical–semantic learning capacities. Other aspects of the learning such as the learning rate and the word length effect were evaluated. The experimental participants scored more poorly than controls on lexical learning, and this deficit was associated with the serial order STM and the attentional capacities. The current study also highlighted that neither the experimental group nor the control group took advantage in lexical learning of semantic information supplement. Our results suggest that children with verbal STM problems learn a smaller number of new words but present a similar way of learning than children without verbal STM problems.

The Effect of Mindfulness-based Programs on Cognitive Function in Adults: A Systematic Review and Meta-analysis

Neuropsychology Review - Mindfulness-based programs (MBPs) are increasingly utilized to improve mental health. Interest in the putative effects of MBPs on cognitive function is also growing. This...     

The development of interindividual sharing of knowledge and beliefs in 5- to 9-year-old children

The authors studied the evolution of interindividual intentionality in children and showed that the sharing of knowledge and beliefs requires more complex operations than those involved in usual false-belief tasks. The authors conducted 3 experiments on 380 children (aged 5 years, 0 months to 9 years, 6 months). They assessed the children's ability to attribute to a character an intended action that was compatible with the belief held by another character interacting with that character. The observed lag in performances is explained both in terms of information processing and at the Piagetian concrete operational level.     

A Study of Pastoral Care,Referral, and Consultation Practices Among Clergy in Four Settings in the New York City Area

Clergy (N = 179) in the catchment areas of four hospitals in New York and Connecticut were surveyed about their pastoral care activities. Factor analysis revealed two separate sets of problems presented in pastoral counseling, with respect to clergys ratings of their competence to address them. The first factor included grief, death and dying, anxiety, and marital problems, in descending order of frequency. The second factor consisted of depression, alcohol/drugs, domestic violence, severe mental illness, HIV/AIDS, and suicide. Clergy were significantly less confident of their ability to deal with Factor 2 problems, yet clergy rarely consulted with mental-health professionals about either type of problem. Less than half of the clergy had training in Clinical Pastoral Education, but those who did tended to feel they were more competent to deal with both types of problems. On average, clergy devoted 3.7 hours per week to visiting patients and nearly 55% said they were definitely more likely to refer a patient to a hospital with a pastoral care department.     

Different working memory capacity in normal young adults for visual and tactile letter recognition task

Thirty-nine young adult participants performing the visual and tactile n-back working memory task were compared. In the visual task, letters were presented on a computer screen and in the tactile task, plastic letters embedded on a board were explored tactually. The amount of incorrect responses increased with increasing memory load in both tasks, but was significantly lower in the visual task. Subgrouping the participants with extreme performances into "skilled" and "poor" performers showed that the best performance was found among "skilled" visual performers, and the worst one among "poor" tactile performers. There was more interindividual variation among tactile than visual performance. We conclude that tactile working memory capacity, measured here by letter recognition and letter memory, is generally more limited and shows more variability than visual memory in normal sighted participants.     

The Refined Extension Principle for Semantics of Dynamic Logic Programming

Over recent years, various semantics have been proposed for dealing with updates in the setting of logic programs. The availability of different semantics naturally raises the question of which are most adequate to model updates. A systematic approach to face this question is to identify general principles against which such semantics could be evaluated. In this paper we motivate and introduce a new such principle the refined extension principle. Such principle is complied with by the stable model semantics for (single) logic programs. It turns out that none of the existing semantics for logic program updates, even though generalisations of the stable model semantics, comply with this principle. For this reason, we define a refinement of the dynamic stable model semantics for Dynamic Logic Programs that complies with the principle.     

The Name Game: Employability Evaluations of Prototypical Applicants with Stereotypical Feminine and Masculine First Names

This study was designed to examine professional human resource managers recommendations and inferences about prototypical applicants who had identical qualifications, in which the presence of periods of unemployment and name (feminine, masculine) of applicants were manipulated. Results indicate that although overall income for female applicants was less than male applicants in some conditions, male applicants were penalized and evaluated more harshly than female applicants when they had experienced periods of unemployment. Specifically, male applicants with employment gaps were seen as less committed and as less hirable than their female counterparts. Overall, male applicants were less likely to be recommended for an interview, and, when they experienced multiple gaps, they were less likely to be recommended for further consideration.     

The neural correlates of implicit and explicit sequence learning: Interacting networks revealed by the process dissociation procedure

In two H2(15)O PET scan experiments, we investigated the cerebral correlates of explicit and implicit knowledge in a serial reaction time (SRT) task. To do so, we used a novel application of the Process Dissociation Procedure, a behavioral paradigm that makes it possible to separately assess conscious and unconscious contributions to performance during a subsequent sequence generation task. To manipulate the extent to which the repeating sequential pattern was learned explicitly, we varied the pace of the choice reaction time task-a variable that is known to have differential effects on the extent to which sensitivity to sequence structure involves implicit or explicit knowledge. Results showed that activity in the striatum subtends the implicit component of performance during recollection of a learned sequence, whereas the anterior cingulate/mesial prefrontal cortex (ACC/MPFC) supports the explicit component. Most importantly, we found that the ACC/MPFC exerts control on the activity of the striatum during retrieval of the sequence after explicit learning, whereas the activity of these regions is uncoupled when learning had been essentially implicit. These data suggest that implicit learning processes can be successfully controlled by conscious knowledge when learning is essentially explicit. They also supply further evidence for a partial dissociation between the neural substrates supporting conscious and nonconscious components of performance during recollection of a learned sequence.
