The Effect of Anxiety Sensitivity and Gender on the Experience of Pain

The association between negative affectivity (NA) and health complaints is thought to reflect a stronger attentional focus on bodily sensations in high NA persons. Perceiving these sensations as rather threatening, high NA persons may scan their internal environment for impending signs of pain and trouble. Using an on-line registration of attentional deployment, we tested whether high NA persons were allocating more attentional resources to internal sensations and less to external stimuli compared to low NA persons. High and low NA participants (N = 68) performed a Stroop-like primary task during a number of trials in which: (1) only an internal; (2) only an external; or (3) both an internal and an external stimulus could occur. Internal stimuli consisted of 7.5% carbon dioxide administrations, causing slight increases in ventilation. An increase in time interval between successive tones served as the external stimulus. Participants were asked to press a button when they noticed one of both events. Results showed that high NA participants: (1) detected the effects of a first respiratory stimulus faster; (2) performed poorer on the tone task when anticipating a respiratory challenge; (3) performed slower on the Stroop task during respiratory stimuli. These findings may indicate that high NA participants show a stronger attentional bias to internal sensations.
