GODOY, Juliana Pardo Moura Campos and GALERA, Cesar. Binding faces and names in working memory requires additional attentional resources. Psychol. Neurosci. [online]. 2011, vol.4, n.3, pp. 341-346. ISSN 1983-3288. http://dx.doi.org/10.3922/j.psns.2011.3.007.
In this study we used the dual-task paradigm to investigate the involvement of attention in the binding of verbal and visual information in working memory. A secondary task, backward counting by threes (BCT), was performed during the retention interval of the primary recognition task based on either visual or verbal information or the binding of both. The BCT affected accuracy and response time. Accuracy was affected only in the binding condition; response time was affected only in the isolated information condition. Together these results suggest that storing integrated visual and verbal information requires more attentional resources than storing information received separately. These results are discussed in terms of involvement of the central executive in storing integrated information in working memory.
