Background: Life expectancy is on rise and the intriguing question is: When does cognitive decline occur among adults with intellectual disability, compared to adults with typical development? This cross-sectional study examined cognitive performance of crystallised/fluid intelligence, working and long-term memory of adults with intellectual…

Sex differences in autism may in part be understood by an atypical sex profile of executive function and non-executive function. In this study, we compared females and males with autism against non-autistic individuals on neuropsychological and self-report measures to examine whether any sex differences in executive function and non-executive…

Purpose: The aim of this study was to determine whether the word-learning challenges associated with developmental language disorder (DLD) result from encoding or retention deficits. Method In Study 1, 59 postsecondary students with DLD and 60 with normal development (ND) took the California Verbal Learning Test-Second Edition, Adult Version…

In recent years, the intersection of cognitive psychology, developmental psychology, and neuroscience with regard to deaf individuals has received increasing attention from a variety of academic and educational audiences. Both research and pedagogy have addressed questions about whether deaf children learn in the same ways that hearing children…

The Rey Auditory Verbal Learning Test, which requires the free recall of the same list of 15 unrelated words over 5 trials, was administered to 21 high-functioning adolescents and adults with autism spectrum disorder (ASD) and 21 matched typical individuals. The groups showed similar overall levels of free recall, rates of learning over trials and…

The author analyzes the scores of inpatient psychiatric patients with varying degrees of cognitive impairment who met criteria for a psychotic disorder on the following tests: the Test of Memory Malingering (TOMM), the California Verbal Learning Test-Second Edition, Conners Continuous Performance Test-Second Edition, and the Brief Psychiatric…

This study investigated the metamemory monitoring abilities of 18 adult survivors of at least moderate traumatic brain injury. Participants also made judgments-of-learning (JOL) predictions of their recall ability immediately or after a list-learning task or after a slight delay. Survivors were as accurate as controls in delayed JOL predictions…

The results of this study indicate that age differences in the recall of high frequency word lists are not related to the total presentation time of the lists but appear to be affected by differences in retrieval processes as a function of age. (JMB)

An investigation of the effects of passive and active rehearsal on developmental processing differences for movement reproduction indicated that active and mature rehearsal had positive results for the younger child. A discussion of the three methods of rehearsal that were used is included. (Author/DF)

This study was designed to analyze developmental differences in the rehearsal strategies of 60 subjects of three age groups. Data revealed significant age differences in recall. Fifth and eighth graders tended to repeat stimulus words immediately after presentation while adults tended to reenter items for additional rehearsal. (LLK)

Examines two sets of variables that influence age-related patterns of text recall--the effects of verbal ability level and text structure variables on text recall of younger, middle-aged, and older adults. Results indicate that age differences in the discovery and utilization of the organizational structure of texts were found to be mediated by…

This study investigated verbal learning when separate tasks were presented simultaneously, with variations in the number of tasks specified to be learned and in the number of tasks presented. Results indicated that the effect of certain independent variables was similar to the effect found when tasks were learned singly. The spacing effect, for…

Reports on 5 experiments investigating the effect of blocking words according to semantic category on ordered recall in adults and young children. (Author/RM)

Background: The relationship between the age of reaching infant developmental milestones and later intellectual function within the normal population remains unresolved. We hypothesised that the age of learning to stand in infancy would be associated with adult executive function and that the association would be apparent throughout the range of…

A cross-sectional study that investigated memory variables in 100 subjects in 4 age ranges (17-22, 40-50, 60-70, and 75-99) found that the 60-70 year olds were more impaired with respect to retrieval than storage and the major problem with memory among the 75-99 year olds was retrieval from short- or long-term memory. Because the study was…
