Abstract:

To identify the effect of narcissistic traits on recognizing threatening expressions, the present study examined how narcissistic traits would affect discriminability (d') and judgment criteria (β) 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.
