Graded capacity-sharing in dual-task interference?
Research suggests that dual-task interference is caused by a central bottleneck (together with response grouping and impaired preparation). The emphasis placed on the 1st response in these experiments, however, may have discouraged the sharing of processing resources between tasks. In the present experiment, instructions placed equal emphasis on 2 choice reaction-time tasks in which stimuli wer...
متن کاملDual-task interference with equal task emphasis: graded capacity sharing or central postponement?
Most studies using the psychological refractory period (PRP) design suggest that dual-task performance is limited by a central bottleneck. Because subjects are usually told to emphasize Task 1, however, the bottleneck might reflect a strategic choice rather than a structural limitation. To evaluate the possibility that central operations can proceed in parallel, albeit with capacity limitations...
متن کاملDual-task interference with equal task emphasis: Graded capacity sharing or central postponement?
When people are presented with multiple tasks at the same time, each involving a rapid choice of actions, substantial interference usually occurs. In the laboratory, this interference between tasks is often measured using the psychological refractory period (PRP) design, where two different stimuli requiring speeded responses are separated in time by a variable stimulus onset asynchrony (SOA). ...
متن کاملAction-effect sharing induces task-set sharing in joint task switching.
A central issue in the study of joint task performance has been one of whether co-acting individuals perform their partner's part of the task as if it were their own. The present study addressed this issue by using joint task switching. A pair of actors shared two tasks that were presented in a random order, whereby the relevant task and actor were cued on each trial. Responses produced action ...
متن کاملA central capacity sharing model of dual-task performance.
The authors present the central capacity sharing (CCS) model and derive equations describing its behaviors to explain results from dual-task situations. The predictions of the CCS model are contrasted with those of the central bottleneck model. The CCS model predicts all of the hallmark effects of the psychological refractory period (PRP) pardigm: -1 slope of the PRP effect at short stimulus on...
