连续和同时线索化条件下的返回抑制容量

THE CAPACITY OF IOR IN SUCCESSIVE AND SIMULTANEOUS CUEING PROCESSES

利用线索—靶子模式进行了返回抑制容量的两个实验。实验一对外周数个位置连续线索化 ,实验二对外周数个位置同时线索化。结果表明 :(1)在连续线索化条件下 ,当线索化位置是相邻时 ,返回抑制容量可以达到 4个 ,当线索化位置是间隔时 ,返回抑制容量只有 1个。 (2 )在同时线索化条件下 ,当线索化位置是相邻时 ,返回抑制容量可以达到 3个 ,当线索化位置是间隔时 ,返回抑制容量只有 1个。结果支持认为存在着两种不同的返回抑制的观点 ,即一种是弥散性的 ,其容量较大 ;另一种是集中性的 。

The capacity of inhibition of return ( IOR) was studied in two experiments with college students as the subjects. The cue target paradigm and the detecting task were used. Experiment 1 was conducted by successively cueing of 1 5 peripheral locations. The results showed that the capacity of IOR was 4 when the successively cueing locations were adjacent and the capacity of IOR was 1 when the successively cueing locations were spaced. Experiment 2 was conducted by simultaneously cueing of 1 5 peripheral locations. The results showed that the capacity of IOR was 3 when the simultaneously cueing locations were adjacent and the capacity of IOR was 1 when the simultaneously cueing locations were spaced. Our results supported the idea that there were two kinds of IOR, one being dispersed with large capacity, and the other being concentrated with very small capacity.
