Recently a great deal of attention has been focused on the health prom
oting benefits that can accrue from revisiting painful emotion. The ra
tionales for revisiting painful emotions include those that assume ree
xperiencing ng emotion per se can be health-promoting. Another view st
ipulates that revisiting painful emotion will only yield benefit if th
ere is some recasting/restructuring of the emotional memory. Research
pertinent to the various rationales is discussed. Then research on the
impact of emotional expression and outcomes studies of therapies desi
gned to enhance emotional experience are reviewed. Good supporting evi
dence is found for the effectiveness of behavioral exposure therapies
where the duration of emotional exposure is carefully controlled, as w
ell as for the salutary impact of talking or writing about trauma by n
ormally functioning individuals. On the other hand, studies evaluating
the impact of experiencing and expressing painful emotion in an unstr
uctured fashion with clinical samples suggest that the process can be
harmful. Incorporating findings from the behavioral exposure literatur
e and from the Pennebaker writing-about-trauma studies, the case for e
voking emotional memories for the purpose of developing new responses
is advanced. The dangers of encouraging emotional experience in absenc
e of acquisition of a new response to the emotion-evoking material are
discussed. (C) 1998 Elsevier Science Ltd.
