All others not marked, P>.15. ASI, anxiety sensitivity index; FPQ, fear of pain questionnaire. Regions identified in the pain>warmth contrast were selected from those listed in Table 1 (and shown in Fig. 1) as representative of those commonly activated in studies of pain (Peyron et al., 2000). Values in parentheses are correlations partialling out individual differences in pain threshold temperatures.
