Multiple Resources, Task-Hemispheric Integrity, and Individual Differences in Time-Sharing
40名被试完成四项信息处理任务，研究发现时间共享效率存在个体差异和任务差异，支持多重资源注意力概念，并发现任务处理半球与反应手同侧时表现更优。
Forty subjects performed four information processing tasks. Three aspects of the data were examined: individual differences in time-sharing efficiency; task-related differences in timesharing efficiency; and interaction of processing codes and response hands. Results showed little concrete evidence for a general time-sharing ability; supported a multiple resource concept of attention; and favored a condition of “task-hemispheric integrity” in which the hemisphere of task processing (spatial or verbal) is the same one controlling the task responding hand (left vs. right). The implications of these results to operator performance in complex systems are discussed.
