While a core function of the working memory (WM) system is the active maintenance of behaviorally relevant sensory representations, it is also critical that distracting stimuli are appropriately ignored. We used functional magnetic resonance imaging to examine the role of domain-general WM resources in the top-down attentional modulation of…

In order to explore the impact of a degraded semantic system on the structure of language production, we analysed transcripts from autobiographical memory interviews to identify naturally-occurring speech errors by eight patients with semantic dementia (SD) and eight age-matched normal speakers. Relative to controls, patients were significantly…

The nature of the comorbidity between Attention-Deficit/Hyperactivity Disorder (ADHD) and Reading Disability (RD) was examined using a double dissociation design. Children were between 8 and 12 years of age and entered into four groups: ADHD only (n = 24), ADHD+RD (n = 29), RD only (n = 41) and normal controls (n = 26). In total, 120 children…

Two studies examined language and understanding of scale models. First, children (N = 16; ages 2;4 to 3;5) received either the "standard" DeLoache model task or a "naming" version (in which children are asked to name the hiding location before retrieving a hidden object). Language ability positively correlated with performance…

The difficulties of learning chemistry are related to the nature of chemistry itself and the methods by which chemistry is customarily taught. Frequently, the way of presenting chemistry does not take into account the psychology of the learner. With senior school pupils (over 1600 were involved) in the Emirates, a series of studies was conducted,…

Although research has shown that older adults are negatively affected by aging stereotypes, relatively few studies have attempted to identify those older adults who may be especially susceptible to these effects. The current research takes steps toward identifying older adults most susceptible to the effects of stereotype threat and investigates…

Deficits in working memory (WM) and executive cognitive control are core features of schizophrenia. However, findings regarding functional activation strengths are heterogeneous, partly due to differences in task demands and behavioral performance. Previous investigators proposed integrating these heterogeneous findings into a comprehensive model…

This study examined the relationship between speech recognition, working memory and conversational skills in a group of 13 children/adolescents with cochlear implants (CIs) between 11 and 19 years of age. Conversational skills were assessed in a referential communication task where the participants interacted with a hearing peer of the same age…

Recent theories have posited that the hippocampus and thalamus serve distinct, yet related, roles in episodic memory. Whereas the hippocampus has been implicated in long-term memory encoding and storage, the thalamus, as a whole, has been implicated in the selection of items for subsequent encoding and the use of retrieval strategies. However,…

Augmentative and alternative communication (AAC) is a discipline that has seen recent developments as a consequence of the worldwide technological revolution. Children with complex communication needs, who benefit from such systems, are now afforded an opportunity to develop independent communication skills. The aim of this paper is to review…

Background: It is recognized that individuals with Down's syndrome have a specific deficit in verbal short-term memory. On the other hand, non-verbal short-term memory seems to be preserved or even be a strong point for these persons. Nevertheless, the extent and specificity of the deficit must be determined. To do so, we carried out a research…

The present experiment investigated the effect of three different presentation modes in children's vocabulary learning with a self-guided multimedia programmes. Participants were 135 third and fourth grade children who read a short English language story presented by a computer programme. For 12 key (previously unknown) words in the story,…

In essentially every domain of neuroscience, the generally implicit assumption that few, if any, meaningful differences exist between male and female brain function is being challenged. Here we address how this development is influencing studies of the neurobiology of learning and memory. While it has been commonly held that males show an…

Implicit measures can be defined as outcomes of measurement procedures that are caused in an automatic manner by psychological attributes. To establish that a measurement outcome is an implicit measure, one should examine (a) whether the outcome is causally produced by the psychological attribute it was designed to measure, (b) the nature of the…

Within the domain-general theory of language impairment, this study examined body posture and hand movement imitation in children with specific language impairment (SLI) and in their age-matched peers. Participants included 40 children with SLI (5 years 3 months to 6 years 10 months of age) and 40 children with typical language development (5…
