Experiments reported here were designed to investigate the drive known as epistemic curiosity which Berlyne had previously demonstrated by showing that subjects given a questionnaire and then a set of statements including answers to the questionnaire recalled more of these answers than subjects not given the questionnaire.

Subjects performed two tasks of logical reasoning at each of six different times of day. In terms of speed, performance on both tests was found to improve markedly from 08.00 to 14.00 and then to fall off fairly rapidly. (Editor)

This research uses a complex task (handwheel assembly) to enable comparison between the performance of mentally handicapped adults and adults from a "normal" population, in the acquisition of new work skills. Results add further support for the notion that the potential of mentally handicapped individuals is commonly underestimated. (Editor/RK)

Results clearly show a preference for correctly classified familiar shapes over their novel counterparts. (Authors)

Begg & Paivio (1969) have proposed that while sentences dealing with abstract matters are normally coded in verbal terms, those concerned with concrete events are internalized as imagery. In two experiments, subjects observed both types of sentence prior to carrying out a distractor task which involved either verbal or perceptual coding. (Editor)

Experiment to determine whether the use of realistic materials would improve performance in a deceptive reasoning problem. (Authors)

On three occasions over a one-year period 23 children aged 3-4 were asked to match target objects with other objects which were similar to the target in shape or in color but not in both. A sequence of matches to each target was asked for. The structure of these sequences is examined for evidence of classificatory abilities. (Editor)

The probable dominance of contralateral hand control and contralateral representation of auditory input are important aspects of the study of cerebral function. A musical task involving bimanual coordination allowed investigation of both the above factors in a crossed and uncrossed sensorimotor relationship. (Author)

Four pursuit-tracking experiments were conducted in an attempt to replicate with adults, Hockey's findings that loud noise increases attentional selectivity. Neither attentional selectivity nor masking of auditory feedback was found to be significant. For Hockey's reply and the authors' rejoinder, see p499-506 of this issue. (SJL)
