摘要
该研究考察了不同工作记忆负荷对形状干扰子注意捕获的影响。采用2(工作记忆高负荷vs低工作记忆负荷)×2(无关形状干扰子出现vs无关形状干扰子不出现)两因素被试内设计,12名被试参加实验。结果发现,以前被认为不能捕获注意的显著性较弱的无关形状干扰子刺激,在高工作记忆负荷下捕获了注意。因此工作记忆负荷对注意捕获有重要影响,刺激显著性较弱的干扰子能否捕获注意主要取决于工作记忆负荷水平。
This study examined different working memory loads on the effect of attentional capture for form distracter. The experiment was a within -subject design of 2 (high vs. low working memory loads) x 2 (irrele- vant form distracters appeared vs. irrelevant form didnt appear). Twelve subjects took part in the experiment. The results showed previously study considered that the irrelevant form distracters could not capture attention due to the weak feature but in high working memory it could capture attention. Therefore, working loads had a major impact on attentional capture. Whether the weak feature could capture attention or pended largely on the level of working memory loads. memory not de-
