Concurrent and subsequent effects of suppressing versus expressing emo
tional (anxious and depressing) and neutral material were investigated
. Subjects either suppressed or expressed thoughts about an anxious, d
epressing, or neutral target situation during an initial thought perio
d. During the subsequent period, all subjects expressed thoughts about
the same target situation. Analyses of thought content revealed that
attempts to suppress the thought did not eliminate its occurrence. Dur
ing the subsequent expression period, subjects in the initial expressi
on condition displayed a significant decrease in statements about the
target situation, indicating habituation, whereas subjects in the init
ial suppression condition showed an increase. Variations in this gener
al pattern were observed on the basis of the different emotional valen
ces of the target situations.
