Dm. Wegner et al., IRONIC PROCESSES IN THE MENTAL CONTROL OF MOOD AND MOOD-RELATED THOUGHT, Journal of personality and social psychology, 65(6), 1993, pp. 1093-1104
The mental control of mood and mood-related thought was investigated.
In Experiment 1, Ss reminiscing about a happy or sad event were asked
to make their mood positive, were given no instructions, or were asked
to make their mood negative. Ss attempting mood control without an im
posed cognitive load were successful, whereas those who attempted cont
rol while rehearsing a 9-digit number not only failed to control their
moods but also showed self-reported mood change opposite the mood the
y intended to create. In Experiment 2, Ss attempting to control mood-r
elated thoughts under cognitive load showed increased accessibility of
those thoughts contrary to the direction of intended control in a Str
oop-type color-naming task.
