The principal objective of this research was to examine the interelations of degree of learning, length of to-be-remembered (TBR) units, and retention interval, with particular reference to the concept of "intraunit interference". (Author/RK)

The present study investigated directly the perceiver's selective control over the processing of hypercapacity verbal or pictorial inputs. (Author)

Ten boys and 10 girls ages 29-35 months, were tested individually on a memory task requiring free recall of two-item lists. No sex differences in response were noted. The mean number of correct responses and the mean number of correct pairs were higher for related items, and, in addition, the children frequently reported the last object they saw…

Blocked presentation of categorical material has been found to increase the number of items recalled by retarded subjects. Three experiments are reported, aimed at discovering the reasons for this facilitation. (Editor)

The present study was designed to examine the relative contributions of perception and memory to the word-frequency effect in the Solomon and Postman design. (Author)

This study sought to assess the ontogenetic course of three classes of size-value phenomena. Size-value phenomena refers to the observation that valued and neutral objects physically equal in size are judged as unequal. Results are discussed in terms of perceptual development. (ST)

Two studies investigated whether variations in the importance of inferences and the salience of premises within a text would affect the probability that the inference would be made. Six stories of about 500 words were used, with eight variations of each story. The target inference, and its plausibility, was constant across all versions. Inference…

This paper describes an investigation of problem sequencing as part of a symposium presenting theoretical concerns and research findings regarding several diverse types of strategies for designing and presenting instructional materials. The first step involved analyzing a set of problems, to determine the knowledge (rules) required for solving the…

Recent publications of longitudinal and sequential analyses of psychometric data have been cited as evidence for "the myth of intellectual decline" with age. This term "myth" has been interpreted by many gerontologists to mean that intellectual functioning does not decline even late in life (except shortly before death). Furthermore, this…

The first section of this report examines, from a developmental perspective, the major theoretical positions dominating the literature on adult cognition. Two criteria are considered. First, how compatible are the theories with the notion that thinking systems develop within specific environments? Second, what are the implicit or explicit…

Investigates the relationship of subvocal speech to recall in 46 4- and 5-year-old children on three muscle sites: lip, chin, and a nonspeech control. (LLK)

In the present study an attempt was made to investigate the duality of encoding mechanisms via instructional sets that were independent of stimulus characteristics. (Author)

Definitions of four rare words were read to 259 undergraduates who were asked to record letters and syllables of the words, at the tip of the tongue. Results corresponded to an earlier study, with morpheme-like clusters evident. Results indicate an organizing memory system for words used in speech. (CHK)
