Chapter 240Figure 1. Structure of a trial in the dot-probe task. Participants were instructed to press the dot on the touch screen, and the reaction time (RT) to the second dot (probe) was measured. With the probe appearing behind the emotional face, the displayed trial represents a congruent trial. Stimuli were taken from the NimStim set of Facial Expressions (Tottenham et al., 2009).QuestionnairesSocial Anxiety Traits We used the self-report version of the Liebowitz Social Anxiety Scale (LSAS; Liebowitz, 1987) to measure social anxiety traits in our healthy sample. The LSAS was originally developed to quantify fear and avoidance in individuals with social phobia and consists of 24 items describing different social situations that typically evoke performance or social anxiety. Fear and avoidance with regard to each item is rated separately on a 4-point Likert scale, ranging from 0 (fear rating: none; avoidance rating: never) to 3 (fear rating: severe; avoidance rating: usually). Sum scores across all items, including both fear and avoidance ratings, are calculated as an overall social anxiety trait measure, with potential scores ranging from 0 to 144. Given that one participant did not complete the questionnaire at all, we had data from 103 participants. Further, for six participants, single items were imputed (see Online Resource 2). Our final sample%u2019s LSAS scores (N = 101; participants without task data excluded) ranged between 4 %u2013 83 (M = 37.1, SD = 17.2). The distribution of the LSAS scores had a skewness of 0.43 and a kurtosis of 2.81, thus being close
