The project was designed to determine if groups (rating high vs. low on a self-report measure of social anxiety at the beginning of the semester) significantly differ from one another with respect to a reaction time/modified dot probe task. Participants were asked to complete the pencil and paper measures of anxiety and the modified dot probe task at the beginning of the semester and again at the end of the semester. Pretest and posttest scores on the self-report measures and the reaction time task were analyzed to determine if any significant change occurred for either of high anxiety or low anxiety participants. Finally, differences between groups from pretest to posttest on these measures were examined.
One-way repeated measures ANOVAs examining the pretest and posttest scores on the Fear of Negative Evaluation Scale (FNE) indicated that the high anxiety group showed a statistically significant reduction in self-reported anxiety. Additionally, a significant positive correlation was identified for all participants at pretest between scores on the FNE and reaction time bias scores on the modified dot probe task for faces expressing negative emotions. Finally, a series of Mann-Whitney U and repeated measures t-tests were conducted to identify any significant changes within groups and between groups from pretest to posttest on the FNE and the reaction time-modified dot probe task. The results and the directions for future research are discussed.
