自恋特质对识别威胁性表情的影响

The Effect of Narcissism on the Recognition of Threatening Facial Expressions

基于信号检测论的框架,考察自恋特质如何影响识别愤怒、恐惧表情时的辨别力和判断标准。结果发现:(1)自恋组识别愤怒表情的辨别力显著高于非自恋组,在识别恐惧表情时自恋组与非自恋组辨别力差异不显著;(2)自恋组与非自恋组识别威胁性表情时的判断标准差异不显著。结果表明,自恋特质对识别愤怒表情的敏感性高于非自恋特质。

To identify the effect of narcissistic traits on recognizing threatening expressions,the present study examined how narcissistic traits would affect discriminability and judgment criteria when recognizing angry and fear expressions within the framework of signal detection theory.Seventy-nine adult participants performed facial expression recognition in both anger-neutral and fear-neutral tasks where angry and fear pictures were signals and neutral pictures were noise.It was found that(1)the discriminability of the narcissistic group in recognizing angry expressions was significantly higher than that of the non-narcissistic group,but there was no significant difference in recognizing fear expressions.(2)There was no significant difference in the judgment criteria of recognizing threatening expressions.These findings suggest that individuals with narcissistic traits are more sensitive to recognizing angry expressions.
