目的:探索返回抑制现象中非线索位置易化效应产生是否受主观反应偏向影响,以及中央线索在此过程中的作用。方法:2(有/无中央线索)*5(线索位置与判断可能出现靶刺激位置间距)两因素混合实验设计。结果:中央线索化条件下,预测靶刺激出现在非线索位置的平均概率显著高于线索位置(p<0.01),无中央线索条件下,预测靶刺激出现在线索位置的概率显著高于非线索位置(p<0.01)。结论:中央线索条件下,返回抑制中非线索位置的易化效应受主观反应偏向影响;无中央线索时反应偏向出现反转,先行线索提示效应明显。
OBJECTIVE: To explore whether the facilitator effect of non-clues in return inhibition phenomenon is influenced by subjective response bias and the role of central clues in this process. Methods: 2 (with / without central clues) * 5 (clues to the location and determine the possible location of the target stimulus spacing) two-factor mixed experimental design. Results: Under the central clue condition, the average probability of predicted target stimuli appearing in the unclue position was significantly higher than that of the clue position (p <0.01). Without the central clue, the predicted probability of the target stimulus appearing in the clue position was significantly higher than that of the non-clue Position (p <0.01). CONCLUSION: Under the condition of central clue, the facilitation effect of returning to restrain the location of the middle-clue is influenced by the subjective reaction bias. When there is no central clue, the reaction bias is reversed and the leading cue prompt effect is obvious.
