本研究采用空白单元格定位任务,探讨序列刺激整合的时间特性.实验1重复前人的实验,验证了时间间隔对整合绩效的影响;实验2系统操纵了对先前刺激的编码时间与时间间隔,结果发现,编码时间越长,记忆的效果越好,虽然会妨碍对随后刺激的知觉,但整合绩效越高;而随着时间间隔的延长,延长编码时间带来的优势逐渐减弱.结论提示,人们能够整合视觉短时记忆和视知觉的信息,而且这种整合的时间特性不同于知觉整合. |

With the empty cell localization task two experiments were conducted to explore the temporal characteristics of sequential stimuli integration.Experiment 1 replicated previous experiments and validated the effect of interstimulus interval in integrating sequential stimuli.Experiment 2,in which the encoding time of the preceding stimuli and interstimulus interval were manipulated,yielded the results that with the increase of the encoding time,the perception of the subsequent stimulus was impaired but the memory for the preceding stimuli would be better and the overall integration performance could be increased.But the advantage due to longer encoding time decreased as the ISI increased.It was suggested that information retained in the visual short-term memory could be integrated with the visual perception,and the temporal characteristics of this integration were different from those of perception integration. |
