Hindsight bias is the phenomenon that after people are presented with the correct answer to a question, their judgment regarding their own past answer to this question is biased toward the correct answer. In three experiments, younger and older adults gave numerical responses to general-knowledge questions and later attempted to recall their…

The episodic buffer component of working memory is assumed to play a role in the binding of features into chunks. A series of experiments compared memory for arrays of colors or shapes with memory for bound combinations of these features. Demanding concurrent verbal tasks were used to investigate the role of general attentional processes,…

This study examines basic number processing (subitizing, automaticity, and magnitude representation) as the possible underpinning of mathematical difficulties often evidenced in deaf adults. Hearing and deaf participants completed tasks to assess the automaticity with which magnitude information was activated and retrieved from long-term memory…

This study used neuroimaging and behavioral techniques to examine the claim that processing capacity limitations underlie specific language impairment (SLI). Functional magnetic resonance imaging (fMRI) was used to investigate verbal working memory in adolescents with SLI and normal language (NL) controls. The experimental task involved a modified…

The aim of the present study was to determine whether monitoring measures are differentially disturbed in dysexecutive patients after frontal lesions. Twelve dysexecutive patients and 12 healthy controls were administered a paired-associates learning task. Their performances on recall prediction, judgment-of-learning (JOL), and feeling-of-knowing…

The author investigated voice context effects in recognition memory for words spoken by multiple talkers by comparing performance when studied words were repeated with same, different, or new voices at test. Hits and false alarms increased when words were tested with studied voices compared with unstudied voices. Discrimination increased only when…

Mothers (N = 67) taught their preschool children crafts while varying emotional expressions (delight, irritation). Mothers' typical expressive styles were assessed by questionnaire. After three weeks, children's memory was assessed with a free-recall interview followed by re-enactment of craft-making with an interviewer. Children of mothers high…

Background: This article provides an introduction to current models of working and short-term memory, their links with learning, and diagnosis of impairments. The memory impairments associated with a range of neurodevelopmental disorders (Down's syndrome, Williams syndrome, Specific Language Impairment, and attentional deficits) are discussed.…

Background: Tourette's syndrome (TS) is a neurodevelopmental disorder associated with fronto-striatal dysfunction. There is debate as to the extent to which TS is associated with cognitive impairment. Some authors argue that any impairments seen are attributable to comorbid psychiatric symptomatology, whilst others have suggested that…

Background: The specificity of impairments in specific reading disabilities (SRD) and specific language impairments (SLI) has recently been questioned, with many children recruited for studies of SRD and SLI demonstrating impairments in both reading and oral language development. This has implications for the results of SRD and SLI studies where…

Background: This study reports the language and memory progress over five years of 30 adolescents and young adults with Down syndrome, and investigates the relationship of earlier phonological memory abilities to later language development. Methods: Tests of nonverbal ability, receptive vocabulary, grammar comprehension, digit span and nonword…

Previous research on typically developing children has shown that their memory for events depends on how they are encoded. As children grow older, they start to mention causal and temporal relationships between events, including psychological causes. Children with specific language impairment (SLI) were studied to disentangle the effects of…

Non-word repetition, in which participants hear and repeat unfamiliar verbal stimuli, is thought to provide a particularly sensitive measure of verbal short-term memory capacity. However, performance on this task can also be constrained by hearing and speech production skills, and by an individuals' linguistic knowledge. This study examined real…

"Drosophila melanogaster" is emerging as a valuable genetic model system for the study of mental retardation (MR). MR genes are remarkably similar between humans and fruit flies. Cognitive behavioral assays can detect reductions in learning and memory in flies with mutations in MR genes. Neuroanatomical methods, including some at single-neuron…

Understanding how memory works is important for success in school, for "all" students. One way for teachers to help students with disabilities learn about memory is to use picture books and then learn strategies. Picture books are useful for students with disabilities because these resources have moved beyond a means to scaffold early literacy…
