O envolvimento da atenção na codificação da informação visuoespacial integrada

Abstract

The objective of this study was to investigate the involvement of attention in the encoding and maintenance of information in visual and spatial working memory. We used a dual task paradigm in which a primary task of spatial localization was performed simultaneously with a secondary attentive task of tone discrimination. The participants' performance (n = 20) in the primary task was affected by the presence and similarity between the tones of the secondary task, and also the instruction to prioritize one task or another. The results indicate that attentive resources (central executive) are involved in encoding and active maintenance of integrated information in visuo-spatial memory, as well as in maintaining the objectives of the tasks to be performed simultaneously.
