Between-task crosstalk has been discussed as an important source for dual-task costs. In this study, the authors examine concurrently performed saccades and manual responses as a means of studying the role of response-code conflict between 2 tasks. In Experiment 1, participants responded to an imperative auditory stimulus with a left or a right…

Examined the effect of attention on infants' responses to briefly exposed visual stimuli. Found that the duration of stimulus exposure in the familiarization phase was positively correlated with the preference for the novel stimulus in the paired-comparison procedure, and processing of briefly presented visual stimuli differed depending on the…

After repeated associations between two events, E1 and E2, responses to E2 can be facilitated either because participants consciously expect E2 to occur after E1 or because E1 automatically activates the response to E2, or because of both. In this article, the authors report on 4 experiments designed to pit the influence of these 2 factors against…

A technique is introduced to study the flow of information through processing stages in choice reaction time tasks. It was designed to determine whether response preparation can begin before stimulus identification is complete ("continuous" models) or if a stimulus must be fully identified prior to any response activation…

This study assessed the differential effectiveness of two types of response delays on correct responding (with communicative gestures) by three individuals with severe mental handicaps to training instructions. Results showed that response delay was effective in increasing the number of correct responses in two of the three individuals. (DB)
