摘　　要：通过控制表征时间进行实验,研究表征程度对选择盲的影响及选择盲中的偏好变化。结果发现:表征时间为4秒时的即时觉察率显著低于表征不限时条件下的即时觉察率;在限时4秒和不限时的条件下,操纵组的评定等级差和选择一致率均显著低于非操纵组。该结果说明:选择盲现象稳定存在;表征时间影响选择盲,长表征时间条件下的选择盲发生率低于短表征时间条件下的选择盲发生率;操纵会增加个体对所选之项的喜爱程度,或减少对非选之项的喜爱程度,甚至使个体的偏好发生反转。The experiment explored the influence of representation time on choice blindness and preferences changes in choice blindness.The results showed that when the representation time was 4 seconds,the concurrent detection rate was significantly lower than that of the unlimited representation time.Furthermore,when the representation time was 4 seconds or unlimited time,the evaluation level difference and the selection consistency rate of the manipulation group were significantly lower than those of the non-manipulation group.The results indicate that the choice blindness is stable.Besides,the representation time is an important factor that affects choice blindness.Specifically,when the representation time becomes longer,the incidence rate of choice blindness becomes lower.Last but not least,the manipulation can increase the individual’s preference for the selected items or reduce the preference for unselected ones,and can even reverse the individual’s preferences.
