Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…

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…

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),…

A group of 73 normal children (ages 8 to 10) was compared to 49 age-matched developmentally dyslexic children of average intelligence on the California Verbal Learning Test for Children (CVLT-C), to determine if reading disability was associated with impaired verbal memory. Dyslexics differed significantly from controls on 9 of the 12 CVLT-C…

Examination of the influence of verbal working memory on sentence comprehension in 12 children with specific language impairment suggested that: (1) these children have less functional verbal working memory capacity than chronological age peers and (2) have greater difficulty managing working memory and general processing abilities than both age…

Large gains in performance, evolving hours after practice has terminated, were reported in a number of visual and some motor learning tasks, as well as recently in an auditory nonverbal discrimination task. It was proposed that these gains reflect a latent phase of experience-triggered memory consolidation in human skill learning. It is not clear,…

Eighteen children (ages 6-16) with attention deficit hyperactivity disorder (ADHD) were compared to 20 controls on both process and product scores from the California Verbal Learning Test for Children. Children with ADHD initially learned the same number of words as controls but showed weaknesses recalling the words after delays. (Contains…

Currently, the reliance on intelligence tests as the primary criterion for the placement of children in school programs has been challenged. Much of the controversy focuses on the insensitivity of these instruments to individual cognitive styles for different subgroups of children. While the issue of whether intelligence tests measure skill…

The syntagmatic paradigmatic model is a distributed, memory-based account of verbal processing. Built on a Bayesian interpretation of string edit theory, it characterizes the control of verbal cognition as the retrieval of sets of syntagmatic and paradigmatic constraints from sequential and relational long-term memory and the resolution of these…
