The Effects of Task Structures, Dynamics of Difficulty Changes, and Strategic Resource Allocation Training on Time-Sharing Performance.

Abstract

A distinction was made between two aspects of time-sharing performance: time-sharing efficiency and attention allocation optimality. The first one is concerned with the level of joint performance of the time-shared tasks. The second one is concerned with the consistency of protecting the high priority task from variations in the task demand. Time-sharing performance was then evaluated as a function of: the task structures of the component time-shared tasks and the strategic training of resource allocation. Time-sharing efficiency was observed to decrease with an increasing overlap of resources that the time-shared tasks utilized. Results also tend to support the hypothesis that resource allocation is more optimal when the time-shared tasks placed heavy demand on common processing resources than when they utilize separate resources. The verbal strategy instructions employed to induce more optimal allocation were more successful for the task pairs utilizing common resources than for those utilizing separate resources.
