Can mindfulness help us ask why, while following a ply? : An experimental study investigating the impact of mindfulness when faced withcontingency changes on the Wisconsin Card Sorting Test

Sammanfattning

Abstract Rule-governed behavior is a unique form of human behavior that comes with many advantages. Rule-following can however become problematic when it makes us insensitive to the consequences of our behavior and undermines our ability to adapt to changes in contingencies. This phenomenon has been hypothesized to play a central role in different psychological problems. In this thesis project, we investigated whether a mindfulness exercise from Acceptance and Commitment Therapy (ACT) could improve people's ability to adapt to changes in contingencies, as measured with the Wisconsin Card Sorting Test (WCST). We also explored whether recently developed self-report questionnaires of rule-governed behavior, the Generalized Pliance Questionnaire (GPQ-9) and the Generalized Tracking Questionnaire (GTQ) could predict the participants' performance on the WCST. In addition, we looked at the association between intolerance of uncertainty (IUS-12) and generalized pliance (GPQ-9). The sample consisted of 45 university students at Örebro university in Sweden. The results revealed that the brief mindfulness exercise did not improve the participants ability to adapt to contingency changes. The questionnaires of rule-governed behavior also did not predict this performance on the WCST. However, we found a novel association between generalized pliance and intolerance of uncertainty, which could be a future research path. Further, generalized pliance and generalized tracking displayed a moderate negative correlation, in line with previous research. Despite limited significant findings in this study, it was an effort to investigate central claims from the ACTand behavioral literature, centered around psychological flexibility and rule-governed behavior.
