The ability of nursery school children to associate pairs of toys was assessed under four experimental conditions: (1) control, (2) subjects manipulating the toys, (3) subjects generating a sentence, and (4) subjects generating a sentence while manipulating the toys. All three subject-involvement conditions produced significantly better…

This paper discusses some methodological, theoretical and physiological issues to be considered in the use of film tests in research relating to visual cognition and memory. One trouble spot in methodology is the use of a square data matrix with an insufficient number of observations in proportion to variables. A second methodological problem…

The purpose of this research was to investigate developmental changes in encoding processes. It attempted to determine the extent to which children of varying ages utilize semantic (denotative or connotative) and acoustical encoding categories in a short-term memory task. It appears to be a reasonable assumption that as associational hierarchies…

Recent theories of verbal memory have hypothesized that memory for a stimulus is not represented by a unitary memory trace, but rather by a coding on several attributes of the event. The present experiment tested the differential forgetting hypothesis in a unique way. Words were presented either visually (V) or auditorally (A) in a continuous…

The present experiment tested the hypothesis that learning under conditions of high arousal should lead to stronger permanent memory and weaker immediate memory than learning under conditions of low arousal. When digital vasoconstriction was used as the measure of arousal, the results confirmed the hypothesis. Learning under high and low arousal…

Eight experiments using as Ss either retarded children, normal children, or normal adults studied the relations of retardation and normal development to the perceptual process of identification. Two experiments were reported on the identification of stimuli varying in either one, two, or three dimensions. Retardates did not perform as well as…

To provide a further test of the paired-associate analogy to retroactive inhibition in free recall, this experiment investigated the effect of presenting both original learning (OL) and interpolated learning (IL) in either blocked category (B) or random (R) fashion. IL-OL Similar (S), IL-OL Different (D), and control (C) conditions were included.…

The memory model, based on information theory proposed by Moser (see SE 013 578), was used to compare the cognitive processing patterns of second and eighth grade Negro and Caucasian students in solving the "parallel circuits" problem. (Connecting two light bulbs and a dry cell so that when both bulbs light, one bulb can be unscrewed,…

From a study on drug treatment effects on the memory and affective functioning of ambulatory geriatric volunteers, the author recommends several methodological accommodations as necessary and expedient to geriatric assessment. Special procedural attention is required by certain characteristics unique to, or exaggerated among, elderly participants.…

The present study investigated why it is that the more concrete the subject noun phrase of a sentence, the more likely the predicate is to be recalled when the subject noun phrase is the cue. The findings were that concretization dramatically influences both the probability of recognition of the subject noun phrase and the probability of recall of…

This speech reports an experiment on memory and verbal ability. The study notes that in previous research, verbal ability has been found to correlate with sensitivity to order, an important component of intelligence. This relationship may be due largely to the greater word store of high verbal scorers. The author's experimental hypothesis is that…

This study provides data that concern the relationships among the usual clinical approach to memory measurement and results from several standard memory tests. (Author)

The prediction that utilization of contextual information will be reduced by the presentation of secondary tasks requiring attention was studied. The importance of a limited-capacity operational memory for reading performance was discussed. (BJG)

Four experiments are reported which employ a recall-reaction time paradigm. The experiments are designed to establish the baseline effects in the paradigm, determine which of these effects should be attributed to the retrieval stage of processing and investigate the effect of semantic memory in this task.
