ABSTRACT

This study examined the influence of SOA on working memory guidance of attention with a modified cue-target paradigm. Specifically, a memory item was initially presented and followed by two squares. The discriminated target was subsequently presented in a matched, non-matched, or baseline condition, then a memory test ended the trial. Five cue-target SOAs (300–1500 ms) were manipulated to elicit the IOR effect. The RT results showed that, (1) a guiding effect occurred at 600–1200 ms SOA, and a trend of the IOR effect at 1500 ms SOA; (2) a facilitating effect to the matched location (matched vs. baseline) was observed at 600 and 1200 ms SOA, and an inhibitory effect to non-matched location (non-matched vs. baseline) was observed at 900 ms SOA. These results indicated that the working memory guiding attention could be modulated by the IOR effect at long SOA.

摘要

本研究使用修改后的线索-目标范式检验了 SOA 对注意力的工作记忆指导的影响。具体来说，最初呈现一个记忆项目，然后是两个方块。随后在匹配、不匹配或基线条件下呈现被区分的目标，然后记忆测试结束试验。操纵五个提示目标 SOA（300-1500 毫秒）以引发 IOR 效果。RT结果表明，（1）在600~1200 ms SOA出现引导效应，在1500 ms SOA出现IOR效应趋势；(2) 在 600 和 1200 ms SOA 观察到对匹配位置（匹配与基线）的促进作用，在 900 ms SOA 观察到对非匹配位置（非匹配与基线）的抑制作用。
