Five experiments studied operations of conceptual masking--the reduction of conceptual memory performance for an initial stimulus when it is followed by a masking picture process. The subjects were 337 undergraduates at the University of Washington (Seattle). Conceptual masking is distinguished from perceptual masking. (TJH)

Investigated whether young children (ages 2-5) could use spatial categorization as a mnemonic strategy. Three experiments found the children capable of spatially organizing objects as a strategy in the service of future retrieval. There were clear developmental trends in the deployment of categorization. (SKC)

Investigated deferred imitation ability for six actions in 14-month-old infants. After a week's delay, infants were tested on their ability to imitate the actions.Those who had been exposed to modeling produced significantly higher instances of the target actions. (SKC)

Describes two experiments showing that experienced readers use text signals to guide their attention to relevant information in a text. Indicates that subjects (1) took longer to read a summary sentence if it was signaled in advance, especially poor readers, and (2) recalled important information better if the information was signaled. (JD)

Analyzed the performance of Alzheimer's patients (N=141) on the Mini-Mental State Examination. Performance on all items showed significant negative correlation with the duration of the illness. The most difficult item was "recall," and the improvement in recall was obtained with cuing. (Author/ABB)

Aphasic (N=15) and non-brain-damaged adults listened to and retold two narrative stories three times in succession. Both aphasic and non-brain-damaged subjects were affected by story structure and increased the amount of information retold across retellings. Non-brain-damaged subjects retold slightly more (statistically insignificant) information…

The use of a rehearsal strategy by 10-, 12-, and 14-year-old mildly mentally retarded children and adolescents (N=39) was investigated using a self-paced recall readiness task. The task allowed Ss to study items in any order as many times as desired. Each group used rehearsal, as indicated by increasing study time patterns and the number of…

The ANDS (A Natural Deduction System) model, described in this article, is a psychological theory of propositional reasoning that makes explicit assumptions about memory and control in deduction. A computer simulation of the ANDS model yields proofs similar to those of untrained subjects. (Author/BW)

A total of 60 children four-, five-, and six-years-old were assigned to memory or control groups and told they could play with toys. Mnemonic mediators were identified on the basis of differences in the behavior of children given memory and play instructions. Use of mnemonic mediators differentiated groups at all ages and increased with age. (RH)

Presents several reconceptualizations of adult cognitive development and its relation to everyday problem solving. Argues that investigation of relations between adult cognitive development and everyday problem solving may be facilitated through causal modeling that includes task characteristics, social context, and personality and motivational…

Examines hypothesis that lack of structural constraint limits children's ability to use context and category cues to search associative memory for episodic information. Second- and fifth-graders and college adults were shown word triplets and asked to recall the final target member of each triplet in a cued recall task. (Author/BE)

Reports on four experiments on how differences in utterance relations influence understanding anaphors, that is, devices that refer back to previously mentioned words or concepts in a discourse. Findings suggest that readers may selectively keep information available if it is likely to be needed for interpreting subsequent input. (SED)

The study used the semantic strategy of stories linking to-be-remembered items and a serial-recall requirement with 27 educable mentally retarded adolescents. In comparison to control subjects, Ss recalled more in the early trials of original learning, but retention after eight months was comparable for the two conditions. (Author/DB)

Free recall performance of children in grades three, five, seven, and nine and of adults was assessed according to a list of categorically related words. Results indicated that seventh and ninth graders were more apt to use associative relations to begin category clusters than were younger children or adults. (Author/BE)

Short-term memory data showed that differences between groups were confined mainly to recall of recency items; within the three older groups, superior readers were superior to competent readers, who in turn were superior to disabled readers; younger competent readers were superior to older disabled readers, despite similarity in reading test…
