Заглавие : Visual working memory and mental transformations
Источник статьи : Psychol. Beitr. - 1996. - Vol. 38, N 3-4. - С. 293-307
Аннотация: In this paper authors look for a dissociation between temporal characteristics of coordinative processes in visual working memory and of transformational episodes in a combined serial transformation task. Selected subjects which differed in their maintenance of patterns had to transform low and high complexity patterns. All subjects had also to fulfil a letter transformation task. The following main results were gained: First, transformation time in the serial transformation task was dependent on the maintenance score, but not on complexity. Coordination cost was not dependent on this maintenance score. So there was a kind of dissociation of co-ordination cost and transformation demand, which was confirmed in an analysis of correlation. In a further step it was shown that coordinative processes are also necessary for the letter transformation task. The temporal characteristics of coordinative processes in the pattern transformation task and the letter transformation task were uncorrelated, which demonstrated domain specificity of these coordinative processes. The general conclusion is that aspects of the functioning of the attentional control component in multicomponent and multimodal theories of memory are domain specific. Библ. 31

Заглавие : Linguistic effects in a visual manipulation task
Источник статьи : Psychol. Beitr. - 1996. - Vol. 38, N 3-4. - С. 251-278
Аннотация: If verbal or phonological encoding interferes with a visual manipulation task, then conditions that reduce linguistic encoding should facilitate performance of the visual task. Moreover, conditions that foster linguistic encoding should hinder performance. These predictions, and associated explanatory mechanisms, were probed using an imaginal subtraction task, in which subjects were instructed to subtract, mentally, a perceived part from a previously seen original composite and to identify the remainder. As predicted, imaginal subtraction improved when visual aspects of the task were emphasized by using tests such as reproduction (drawing) or recognition of the remainders. Imaginal subtraction declined when linguistic processing was encouraged by (a) allowing phonological recoding, (b) requiring subjects to explicitly label the original composites, and (c) using linguistically-oriented final tests, such as naming the remainder aloud or writing its name. Although phonological recoding, retrieval interference, and overshadowing may have contributed to the results, a transfer-of-appropriate-processing view yielded a more encompassing explanation.
