An adaptive network model is proposed to represent the structure and processing of knowledge. Accessibility of subjects' stored information was measured. Relationships exist among (a) frequency of verifying a test relation, (b) other relations involving concepts used to evaluate test relation, (c) frequency of verifying those relations. (CHK)

Control of the mechanisms of memory may eventually come to pass, thanks to ingenious new research with goldfish and rats. (Editor)

The structural features extracted for the schizophrenics, nonschizophrenic psychiatric patients, and normals were very similar to each other. A group difference was found in the subject's sorting strategy, but its effect on the main findings was judged to be minimal. (Author)

A major error in cognitive science has been to suppose that the meaning of a representation in the mind is known prior to its production. Representations are inherently perceptual--constructed by a perceptual process and given meaning by subsequent perception of them. The person perceiving the representation determines what it means. This premise…

Results are reported which show that the facilitating effect of recall on recognition is quite substantial. (AM)

The development of the ability to use taxonomic, phonemic and sense impression categories as dimensions of encoding was investigated using third and fifth graders and college students. (ED)

Some of the issues associated with the lack of a precisely stated theory of memory organization are considered. The first section provides an overview of the concept of organization. Emphasis is on problems associated with the definition of organization, especially the distinction between organization as a process and as the product of a process.…

The study investigated the ability of 80 mildly mentally retarded students (19 to 17 years old) to make accurate judgments of textual idea importance and to differentially and spontaneously remember important rather than unimportant ideas. Ss were assigned to one of six conditions which differed as a function of whether importance judgments were…

Memory storage and retrieval of learning disabled (LD) and normal children at two age levels (8-9 years and 11-12 years) were compared using a multitrial free recall paradigm. Stimuli were two lists of 20 high frequency nouns. Each child was tested individually on both lists on different days; one presentation was blocked, one random with…

Six studies were performed investigating the relationship between digit span (DS) capacity and other memory and problem solving tasks: (1) Ss were administered a DS test, an aurally presented mental addition test, a similar multiplication task, and a written timed division test. DS correlated only with the second; (2) Ss were required to…

This study tested the hypothesis that the memory of meaningful material can be reactivated without relearning by means of hypnotic suggestion. Very susceptible (T) and non-susceptible (UT) subjects were sought from among those who volunteered for the experiment. Two forms of a memory test for connected meaningful material were developed. Each form…

Subjects in an independent groups free learning experiment recalled list of low- or high-arousal words, matched for imagery and frequency and exposed randomly for 3 seconds and 9 seconds. Extrapolating neural consolidation theory to previous work on serial position effects led to the predictions that (1) arousal facilitates primacy; (2) arousal…

This research was directed at determining whether the new item priority (NIP) effect in free recall was a result of an experimental artifact produced by the joint action of the serial position effect and the randomization of items over trials, or a consequence of a strategy of recalling newer items before older ones. In the experiment, subjects…

This experiment tested the hypothesis that paired-associate learning accompanied by high arousal should lead to stronger permanent memory and weaker immediate memory than paired-associate learning accompanied by low arousal. During continuous recording of skin resistance and heart rate as measures of arousal, 32 Ss were given a one-trial,…
