Figures 3a-c.

The probability of late phase responses following allergen skin tests as a function of anxiety and stress or control condition. Skin tests were performed (3a) before the stressor or control tasks, (3b) immediately after the stressor or control tasks, and (3c) the morning following the GCRC stressor or control session as a function of stress or control condition and anxiety. These responses develop 6-8 hours following challenge, and thus skin tests performed before the stressor could still be influenced by it. Anxiety enhanced the effects of stress on late phase responses at each of the three time points.
