Response mechanisms underlying kinesthetic short-term memory.

The variables of reproduction cue, activity during retention interval, and orientation of the recall movement were manipulated to assess simultaneously the viability of two hypotheses of motor short-term memory. Data partially supported hypotheses as positive response biasing was evident in recall after a filled retention interval (Pepper & Herman, 1970) and that for a given range of movements some adaption to a central reference level occurred (Laabs, 1973).

Role of selected encoding strategies on short-term retention of kinesthetic information.

30 volunteer subjects were required to use either a counting encoding strategy or an imagery encoding strategy to facilitate recall of information from short-term storage. Subjects were also required to use two reproducation cues in combination with two encoding strategies. Analysis indicated no differences between the accuracy at recall of subjects using imagery or counting strategies of encoding, nor was the predicted interaction between encoding strategies and reproduction cue supported.

Role of extended perceptual experience upon haptic perception of nonrepresentational shapes.

The influence of amount and type of exploratory activity upon 3 male and 5 female undergraduates' ability to detect the symmaterical or asymmetrical characteristics of individually presented plastic nonrepresentational shapes was examined. A decrease in scanning time and number of identification errors between the first and fourth days of testing indicates that extended perceptual experience plays a major role in the efficient pick-up and utilization of haptic information. A signal-detection analysis demonstrated that the use of a simultaneous-apprehension scanning strategy resulted in greater sensitivity to asymmetrical shapes than did the use of a simultaneous-apprehension scan. The data support the hypothesis that experience, the form parameter of symmetry, and the type of scanning strategy used to explore a stimulus function together to influence haptic perception of nonrepresentational shapes.
