Abstract: Continuous attention to negative stimuli is a necessary condition for individuals to maintain their worries. Previous research has also shown that intolerance of uncertainty is one important factor that contributes to symptoms of generalized anxiety. A research question then emerges: do individuals with generalized anxiety pay particular attention to negative stimuli under uncertain situations? Little research has been conducted to answer this question. Consequently, the present research aims at demonstrating the attentional bias of individuals with generalized anxiety.
Using the dot-probe task paradigm, two experiments were conducted to examine the attentional bias of individuals with generalized anxiety under ordinary versus uncertain situations. Using the Chinese version of Penn State Worry Questionnaire, we tested 1135 college students among which 60 students with generalized anxiety and 60 control students were selected. The 120 students participated in a test under ordinary situations in Experiment 1 and in another test under uncertain situations in Experiment 2.
Results showed significant differences between students with generalized anxiety and control students in their attentional bias under uncertain, rather than ordinary situations. Under uncertain situations, students with generalized anxiety paid more attention to negative stimuli than their counterparts without generalized anxiety did. Additionally, they also felt more stressful and anxious under uncertain situations than their counterparts did.

Key words: generalized anxiety, attentional bias, uncertain situations
