The ability of preverbal infants to abstract a prototypical representation of a category, when presented with examples of an artifically constructed category, was investigated. It was determined that infants could process visual information constructively and could take a more active role in category formation than previously believed. (Author/MH)

Type I incidental learning (in which Ss are exposed to stimulus materials without instructions to learn, and then Ss' retention is unexpectedly tested) of 112 educable mentally retarded children (6-13 years old) was investigated. (Author/CL)

Discussed is the college teacher as lecturer. Three basic areas are looked at: attention mechanisms, information processing, and memory. Nine suggestions are presented which, if employed, will improve the lecture process. (KC)

The author presents findings from brain hemisphere research indicating a complex dual memory process which separately and simultaneously processes input through visual and verbal encoding strategies. He draws implications from this for educational goals, instructional methods, and student evaluation procedures. (SJL)

Reliabilities for immediate recall of females, aged 71-93 years, on subtests were adequate; those for delayed recall were less adequate; and those for percentage-retained scores were unacceptable. Recommended the development of an alternative form of Russell's revised Wechsler Memory Scale. (Author/BEF)

Memory of preschool children (four years of age) for companions was investigated by comparing interview data using a picture sociometric technique with observational data on actual play companions. Subjects were 15 boys and girls. (Author/MP)

The semantic memory search process was examined in second graders (N=30) under an induced imagery and a control condition. (MP)

Adults aged 64-76 were tested on several measures of spatial rotation ability. Memory for the test stimulus was an important factor in the performance of those who generally performed at a high level and not for those who performed poorly. (Author)

This study examines an extreme case of the influence of motives on memory. Eight-year-old children judged which of two sentences had been read to them 10 days earlier for 20 sentence pairs. (CM)

Inference tasks emphasizing the acceptance of lack of closure (ALC), memory, and hypothetico-deductive reasoning were administered to 67 males and 74 females ranging in age from 5 to 12 years. Results suggest that the relationship of ALC to age is mediated by memory development rather than by logical development. (JMB)

Subjects were 943 mestizo and Quechua Indian children aged five and six years who lived in jungle villages near Lanas and in slum settlements in Lima, Peru. Some six year olds attended school and others did not. The children were tested with a task that assessed memory for central and incidental features of drawings. (JMB)

Presents a series of four experiements designed to test the view that the process where a spoken suffix impairs retention of a sequence's last item has a different basis from that producing impairment of the retention of an earlier item. (AM)

Spatial memory for configurations was studied in 36 congenitally blind, late-blinded, and sighted adults. (Author/DLS)

A total of 45 fifth grade students were the subjects of an experiment offering support for a component of learning strategy (memory imagery). Various theoretical explanations of the image-tracing phenomenon are considered, including depth of processing, dual coding and frequency. (MS)
