The present study extends the prior research on cognitive defusion by
examining behavioral change on a simulated slot machine. Participants were
exposed to an on-line slot machine fully manipulated by an experimenter. A
randomized control pretest-posttest design was used to assess the differences in
gambling persistence and risk across groups (Defusion Control, Defusion without
Information, and Defusion with Information). Results yield a statistically
significant difference in persistence across time and a non-statistically significant
difference in risk across time. Findings from this study suggest that defusion
exercises, when combined with accurate gambling related information, may help
reduce persistence of gambling behavior.
