The study evaluated the semantic system of mentally retarded adults (N=32) to determine whether they encode information in semantic memory on the dimensions of item prototypicality and list organization. Results suggested that interference effects inhibited encoding by organization and typicality. (DB)

Reports that both learning-disabled (LD) and non-learning-disabled (NORM) children recalled disproportionately more adjacent words than semantically related or spaced words in a free recall task. Spaced words were less likely to be recalled by the younger children and by the LDs. NORMs' recalls were governed by purposive semantic processing to a…

This study examined conceptual relationships in semantic memory using an indirect priming technique in high-functioning autistic adolescents and controls. The autistic subjects and controls showed similar semantic priming effects. However, correlations with nonverbal cognitive measures for the autistic subjects suggests that semantic processing in…

The research study investigated the memory and metamemory abilities of four severely to profoundly deaf students with bilateral sensory-neural loss, between the ages of 9 and 20 years. Metamemory was investigated with four modified subtests identified as "story list,""study plan,""retrieval event," and "opposites-arbitrary." Encoding was…

A study of 21 patients with Alzheimer's Disease and 25 with vascular dementia, the two most common forms of dementia, investigated language impairments in the dementia syndrome to see if analysis of language disturbances is helpful in differential diagnosis. Diagnostic assessment included a neurological examination, detailed medical history,…

Corrects errors in "A Developmental Study of Learning Disabilities and Memory" by Stephen J. Ceci (Volume 38, Number 2 1984), pages 352-371. (AS)

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…

This study investigated taxonomic clustering and use of frequency associations as features in the semantic memory of children (n=30 in grades two and six) with learning disabilities (LD). Results suggested that, when individual child-generated word lists (i.e., meaningful) are used, children with LD may not be impaired in their ability to utilize…

The incidental memory of young children was tested for words or words plus pictures that were initially presented under orienting conditions. These conditions required responses to acoustic or semantic qualities of the stimuli and an affirmative or negative response to the orienting questions. (PCB)

Compares the semantic processing skills of younger adults (mean age 25) and older adults (mean age 68). After reading a sentence, subjects performed a task in which responses did not depend on retention. Results provided no evidence for age-related changes, including those associated with access to implied information. (Author/RH)

This paper reviews work on the representation of knowledge from within psychology and artificial intelligence. The work covers the nature of representation, the distinction between the represented world and the representing world, and significant issues concerned with propositional, analogical, and superpositional representations. Specific topics…

With reference to Chinese language and its unique orthography, evidence for language-related differences in manners of information processing is reviewed. These differences include visual form perception, manipulation of numbers, and memory versus manipulation and elaboration of verbal information. (Author/RH)

Developmental differences in the relative salience of features in concept representations in semantic memory and their contributions to differences in cued recall were examined in two experiments. Subjects were second graders, fifth graders, and college students. Results showed that recall varied with feature salience, with salience greatest for…

Reports on two experiments that investigated sex differences in the use of organization strategies in free recall with categorizable and unrelated word lists across age in elementary school. Shows sex differences were pronounced across the ages tested and consistent with principles of strategy development, with males showing a developmental lag in…

Level of state test anxiety and depression were related to encoding strategy (imagery versus sematic instructions) in a study of sentence memory. Subjects were 80 female undergraduate students. Negative effects for test anxiety were found in both strategy conditions. Negative effects were found for depression when the semantic encoding strategy…
