Abstract

The predictions of the central bottleneck and resource allocation models of dual-task performance were examined in a psychological refractory period dual-task experiment. Cloze picture-naming was the primary task and the secondary task was either tone identification or lexical category identification. The nature of the secondary task significantly affected primary task naming RTs and stimulus onset asynchrony affected naming RTs only when the secondary task was lexical categorization. These findings are more consistent with the resource model than the bottleneck model.
