目的:探讨内源性注意与外源性注意的相互作用机制。方法采用Yantis的非突现范式。结果实验一研究发现在较简单的探测任务下,内源性注意与外源性注意没有交互作用,互相独立。实验二研究发现在较复杂的辨别任务下二者存在交互作用。结论二个实验结果验证了Berger等人提出的理论,即任务负载程度决定内源性注意与外源性注意的相互作用,在低负载即简单任务下,内源性注意与外源性注意互相独立,而在高负载即复杂任务下,二者才存在相互作用。
Objective: To explore the mechanism of interaction between endogenous attention and exogenous attention. The method uses Yantis’ non-emergent paradigm. Results In the first experiment, we found that endogenous attention had no interaction with exogenous attention and was independent of each other under the simpler exploration tasks. In the second experiment, it is found that there exists an interaction between the two under more complex discrimination tasks. Conclusions The two experimental results validate the theory proposed by Berger et al. That the degree of task load determines the interaction between endogenous attention and exogenous attention. Under low load or simple task, endogenous attention and exogenous attention to each other Independence, and under the high load or complicated task, there is interaction between the two.
