Using a Stroop color naming task, a previewed condition was designed that the distractor of the upcoming Stroop stimulus was presented in advance as a cue. With the foreknowledge of the upcoming distractor, participants were instructed to inhibit this previewed distractor. Experiments 1-3 indicated that participants can benefit from distractor previewing. Color naming was faster when the distractor was previewed than when no cue or no valid cue was presented. By estimating the Stroop interference effect as the difference between the incompatible condition and the neutral condition, Experiment 4 further demonstrated that distractor previewing can decrease the Stroop interference effect. Experiments 5-10 were designed to evaluate hypotheses of distractor previewing, including facilitation of distractor processing, attending part of the cue, temporal segregation, expecting possible targets, and intentional inhibition. Experiment 5 showed significant effect of distractor viewing when incompatible and compatible trials were used. However, the benefit of distractor previewing was decreased when compatible trials were presented. Experiments 6-8 demonstrated significant effect of distractor previewing when cues and distractors differed in forms. Moreover, the benefit of distractor previewing was less when cues and distractors were different in forms than when they were identical in forms. In Experiment 9, there were conflict trials that the previewed item cued the target color rather than the distractor word. In comparison to the neutral condition, a cost was obtained for these conflict trials. Finally, the cue validity was removed in Experiment 10, and no effect of distractor previewing was observed. These results from Experiments 5-10 support the hypothesis of intentional inhibition. Using Stroop negative priming as the index of passive inhibition, intentional inhibition was compared to passive inhibition in Experiments 11-16. Experiments 11-14 showed that while passive inhibition was sensitive to short-term memory load, intentional inhibition was less sensitive to the load of short-term memory. Experiments 15-16 indicated that while the effect of intentional inhibition could last at least 6,500 ms, the effect of passive inhibition could not last as long as intentional inhibition. These results demonstrate differences between passive and intentional inhibition.緒論 1 抑制的心理學研究 2 注意力的被動抑制與主動抑制 19 注意力的被動抑制—負向促發效果 19 注意力的主動抑制 38 第一部份：干擾物預視效果的展現 53 實驗一：干擾物預視對於Stroop唸色作業的影響 53 實驗二：空間注意力與警醒相關因素的排除 56 實驗三：知覺整合的排除 58 實驗四：干擾物預視對於Stroop干擾效果的影響 60 小結 56 第二部份：干擾物預視效果的理論檢驗 65 干擾物預視效果的可能解釋 65 實驗五：干擾物預視對於一致組的影響 71 實驗六—八：線索與干擾字知覺不相似下的干擾物預視效果 77 實驗九：引入衝突線索組以檢驗抑制效果的存在 87 實驗十：線索預測力的移除 91 小結 93 第三部份：Stroop作業中主動抑制與被動抑制的資源需求 95 實驗十一—十三：記憶負荷量對於被動抑制的影響 95 實驗十四：記憶負荷量對於主動抑制的影響 103 小結 105 第四部份：Stroop作業中主動抑制與被動抑制的時程 107 實驗十五：被動抑制的時程 108 實驗十六：主動抑制的時程 112 小結 116 綜合討論 117 現象：干擾物預視效果 118 理論：干擾物預視效果的機制 119 主動抑制與被動抑制的對比 125 抑制效果的特質 126 主動抑制效果的意涵 129 總結 137 參考文獻 139 作者簡歷 1651000497 bytesapplication/pdfen-US注意力控制抑制Stroop選擇注意力top-down controlattentional inhibitionselective attentionotherhttp://ntur.lib.ntu.edu.tw/bitstream/246246/55901/1/ntu-95-D90227005-1.pdf
