                             quicker identification of the safety signal and speedier subsequent recovery

                             from stress anticipation.
                                There is now preliminary neuroimaging and behavioral evidence to

                              suggest that nonresilient individuals are more likely to adopt the “better
                             safe than sorry” orientation in anticipation of an uncertain stressor, whereas
                             resilient individuals are more likely to adopt the “wait and see” orientation.
                             Waugh, Wager et al. (2007) reported that when anticipating a possible (0.50)
                             negative stimulus, nonresilient participants exhibited greater activation of
                             the LOFC, a brain region associated with the anticipation of punishment
                             (O’Doherty et al., 2001). When presented with the neutral picture that could
                             have been aversive, nonresilient participants also demonstrated increased
                             duration of activation in the insula, a region of the brain associated with core

                             negative affect. In addition, LOFC activity during the anticipation period
                             predicted the insula response to these ‘relief’ neutral pictures. Th ese results
                             suggest that nonresilient people generate a preemptive emotional response
                             (LOFC)—“better safe than sorry”—which then affects their ability to recover


                             from the threat (longer affective response to neutral pictures aft er threat).
                             Resilient participants, on the other hand, exhibit minimal activity—“wait
                             and see”—during anticipation and thus are better able to recover (neutral
                             picture, the threat is gone).
                                In summary, differential recovery when an anticipated stressor does not

                             occur depends to some extent on individual differences in anticipatory emo-

                             tion and physiology. If an anticipated stressor is perceived to be very likely
                             to occur—whether as determined by objective statistics or by individual bias
                             toward worst outcome certainty—anticipatory stress will be associated with
                             preemptive emotional and physiological reactivity that serves to prepare the
                             body for action (Waugh, Wager et al., 2007). If the anticipated stressor then fails
                             to occur, the heightened anticipatory response will likely require extra time and
                             energy to downregulate and recover. Alternatively, if an anticipated stressor is
                             viewed by actual or perceived probability to be unlikely to occur, emotional
                             and physiological anticipatory responses will be less dramatic, reflecting a “wait

                             and see” strategy that conserves energy and facilitates faster recovery.
                                An interesting question for the future research is how the ability to learn
                             environmental contingencies (Charney, 2004) is related to anticipation and
                             recovery from stress. It may be that an enhanced ability to learn and thus
                             assess environmental contingencies supports more appropriate or eff ective
                             strategy selection. Alternatively, strategy selection may affect learning or

                             assessment. We propose that the causal relationship between learning and
                             strategy selection is generally reciprocal, beginning as an  initial emphasis
                             on strategy selection in novel or unfamiliar situations (new environmental
                             contingencies to be learned) and followed by reference to previously learned
                             contingencies in the course of subsequent strategy selections.
