| Summary: | A normative experimental study was undertaken to establish whether engaging in positive, negative,
and neutral mental imagery affected the reaction rate of participants to positive, negative, and
neutral word stimuli. The sample consisted of computer literate, English speaking participants with
no history of clinical disorders. A total of 80 participants took part in the study, with 40
participants from either gender. The results of a factorial ANOVA indicated that the type of mental
imagery engaged in had a significant effect on the rate at which participants responded to stimuli
(p=.00023, F=8.4057), whilst the emotional valence of the stimuli did not have a significant
effect (p=.30503, F=1.1877). However, the interaction between the type of mental imagery and
the emotional valence of the stimuli was highly significant (p=.00794, F=3.4576), thereby
indicating that engaging in positive or negative mental imagery did bias participants towards a
faster reaction rate to positive or negative stimuli respectively. === M.A. (Psychology) === Psychology
