Dissociations and Dependencies between Speed and Accuracy: Evidence for a Two-Component Theory of Divided Attention in Simple Tasks.

Pashler, Harold

Cognitive Psychology, v21 n4 p469-514 Oct 1989

How the dual-task interference effects, observed when subjects attempted to simultaneously perform two simple tasks, are related to capacity limitations in perceptual processing of complex visual displays was studied. Results for a total of 110 undergraduates in 6 experiments support a 2-component theory of divided attention. (SLD)
