Three experiments are reported in which rats first received 50 escapable or inescapable signaled-shock trials. The results of the experiments are discussed in terms of a learned active-inactive predisposition to respond. (Editor/RK)

The effects of a visual distractor on vigilance task performance were examined in a sample of 35 learning disabled and 35 normal boys 8-12 years old. (Author/DB)

Forty infants, 3- to 12-months-old, participated in a study designed to differentiate the auditory response characteristics of normally developing infants in the age ranges 3 - 5 months, 6 - 8 months, and 9 - 12 months. (Author)

When stimuli differed on two dimensions (size and shape), either of which furnished enough information for a correct response, eight educable retarded adults were faster to discriminate than when stimuli differed only on dimension. (Author)

Suggests a way of using factor analytic techniques to supplement multidimensional scaling in such a way as to provide a firm basis for evaluating multidimensional representations. (Author/RC)

This experiment investigated the time course of recall (from 1/2 to 5 min.) for pictorial and verbal inputs. A hypermnesic (incremental recall) effect was found for pictures but not words, and was shown to be independent of multiple-recall trials. (Editor)

The present paper was an attempt to look upon word meaning as a process occurring within the individual's cognitive functioning. (Author/RK)

The objective of this investigation was two-fold; to examine systematically the importance of visual-holding cues during inter-response intervals, and to monitor concurrent visual behavior in an operant learning situation which incorporated a spatially displaced feedback locus. (Author)

Two experiments were carried out investigating the extent to which recognition responses to pictures are based on specific detail vs. general information. (Editor)

The aim of the present study was partly to see whether the trade-off between item and attribute memory was a reliable phenomenon and partly to examine the strategies used by subjects in this task. (Author/RK)

A study investigated whether positive response to humor in a speech would enhance audience evaluation of the speech/speaker. A short informative speech on "listening" which included nine relevant jokes was audio tape-recorded in two versions, one in which each joke was punctuated by laughter, and one in which a stony silence greeted each…

While it is often assumed that a single mechanism underlies varied experimental evidences of selectivity, Berlyne (1969) suggested that attention-like selectivity may take place in a number of quite separate neural systems. This study examined the issue of visuospatial attention by investigating covert orientation or "looking out of the corner of…
