采用ERP技术,以线索提示任务检验了性别刻板印象在返回抑制下的激活过程.实验以性别特征词为线索刺激,性别范畴词为目标刺激,要求被试忽略线索与目标语义仅对目标空间位置做出判断.反应时和ERP显示,线索化条件下刻板语义激活对位置判断产生显著影响,体现为女性刻板语义冲突增强了返回抑制.但非线索化条件下未观察到任何效应.实验结果表明,特定任务下性别刻板印象能够诱发注意偏向,但此过程易受注意线索影响,显示其有条件性.
This ERP study investigated the mechanism of gender stereotype activation in the inhibition of return(IOR) by using a modified spatial cuing task. Gender traits were employed as the spatial cues and the gender labels were employed as the targets. Subjects were instructed to respond to the target' s spatial location according to the cue' s position without caring about their semantic information. As results, the semantic stereotyping evoked by violation of feminine traits was activated, and then moderated the IOR processes in the cued condition relative to the uncued condition. To sum up, this effect demonstrated that the semantic stereotype compatibility could moderate the Posterior Attentional Net and elicit attentional bias in certain conditions.
