演講摘要

Reduced reaction times to conflict situations are observed when the preceding event was also an incongruent compared to a congruent situation. Such a reduction, known as congruency sequence effect (CSE), is considered to reflect a control process that monitors conflict situations and effectively adjusts current behavior to avoid interference from distractors. Some evidence has suggested that effects from this process can persist for some time after a conflict trial has been presented, influencing the response to subsequent trials. This remains to be tested in humans, however. T o approach this question, we adopted a prime-probe arrow task to induce response compatibility . Meanwhile, EEG was recorded to measure the mechanism underlying the CSE. Short (133 ms) or long (500 ms) inter-stimulus intervals (ISI) between prime and probe were manipulated to investigate whether the duration of the ISI affects CSE. Our behavioral results showed a typical compatibility effect in the current trials and a significant CSE irrespective of whether the ISIs were short or long. In line with the behavioral results, the amplitude of the N2 reflected the conflict level on current trials. Analyzing trials according to the content of the previous one, we saw an increased probe N2 where the prior trial was incongruent and where the ISI was long. Interestingly, we did not, however, see any difference during the ISI period itself. The preliminary results suggest that whilst there may be a persistent CSE, it may require a quiescence period before it affects subsequent stimulus responses.
