Differentiating between early-onset bipolar disorder (BD) and attention-deficit/hyperactivity disorder (ADHD) can be difficult. Memory problems are commonly reported in BD, and forgetfulness is among the diagnostic criteria for ADHD. We compared children and adolescents with BD (n = 23), ADHD combined type (ADHD-C; n = 26), BD + ADHD-C (n = 15),…

We examined whether repeated reactivations of a context memory would prevent the typical amnesic effects of post-training damage to the hippocampus (HPC). Rats were given a single contextual fear-conditioning session followed by 10 reactivations, involving a brief return to the conditioning context (no shock). Subsequently, the rats received sham…

The purpose of the present study was to investigate the validity of the Working Group's Autobiographical Memory Test as a dementia screening tool for individuals with moderate to severe intellectual disabilities (ID). Twenty-one participants with Dementia of Alzheimer's Type (DAT) and moderate to severe ID and 42 controls with similar levels of ID…

Considering the high risk for individuals with amnestic Mild Cognitive Impairment (A-MCI) to progress towards Alzheimer's disease (AD), we investigated the efficacy of a non-pharmacological intervention, that is, cognitive training that could reduce cognitive difficulties and delay the cognitive decline. For this, we evaluated the efficacy of a…

Recognition memory impairment after selective hippocampal lesions in monkeys is more profound when measured with visual paired-comparison (VPC) than with delayed nonmatching-to-sample (DNMS). To clarify this issue, we assessed the impact of stimuli similarity and encoding duration on the VPC performance in monkeys with hippocampal lesions and…

Remembering events frequently involves associating objects and their associated locations in space, and it has been implicated that the areas associated with the hippocampus are important in this function. The current study examined the role of the perirhinal cortex in retrieving familiar object-place paired associates, as well as in acquiring…

This study examines the effects of task familiarity through the use of subtitled videos on negotiation of meaning in an online task-based language learning (TBLL) environment. It explores the amount of negotiation of meaning produced by non-native speakers (NNSs) aimed at improving input comprehension to enhance second language acquisition. Ten…

This article shows the cognitive and motor-perceptive effects of the application of a cognitive stimulating program through motor function on 234 elderly people. The assessment was carried out prior to and after the program. Significant improvements in the experimental group were observed (p [less than or equal to] 0.05) in six of the eight…

The study compared the academic achievement, as measured by final examination scores, of an experimental group of undergraduate educational psychology students who were provided with concrete mechanisms designed to promote metacognition and the use of specific encoding strategies to the achievement of a control group of similar students who were…

The triple-code model, cognitive neuroimaging and developmental behavioral data suggest a specific association between phonological processing and arithmetic fact retrieval. Accordingly, individuals with deficits in phonological processing, such as individuals with developmental dyslexia, are expected to show difficulties in arithmetic fact…

Difficulties in phonological processing and reading that characterize developmental dyslexia have been suggested also to affect those with attention-deficit/hyperactivity disorder (ADHD). However, it is not known to what extent various intervening factors, such as low intelligence quotient or age, explain the observed difficulties. In this study,…

The comparison of the neurocognitive functioning of people with pediatric bipolar disorder (PBD) with a control group shows that the developmental progress in executive functions and verbal memory of those with PBD was significantly less than those in the control group. The results were seen after comparing data from baseline cognitive tests and a…

Cognitive processes require a functional interaction between specialized multiple, local and remote brain regions. Although these interactions can be strongly altered by an acquired brain injury, brain plasticity allows network reorganization to be principally responsible for recovery. The present work evaluates the impact of brain injury on…

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…

Lack of insight is a core diagnostic criterion for behavioral variant frontotemporal dementia (bvFTD), and is believed to be intact in the early stages of primary progressive aphasia (PPA). In other neurological conditions, symptom-specific insight has been noted, with behavioral symptoms appearing especially vulnerable to reduced insight.…
