Abstract Details

2016, Doctor of Philosophy, Ohio State University, Psychology.
Previous research has shown that individual differences in self-regulatory capacity, including resting heart rate variability (HRV), moderate thought suppression success. However, it remains unclear to what extent individual differences in self-regulatory capacity predict thought suppression success under conditions of cognitive load. Furthermore, few studies have investigated whether utilizing thought suppression can impact an individual’s perception of their self-regulatory capacity (i.e., self-reports of effortful control). The current study aimed to further explore the relationship between predictors and consequences of thought suppression ability and sought to replicate the findings from previous work. The current study used a standard thought suppression paradigm that included a cognitive load condition in which participants recorded occurrences of a personally relevant intrusive thought over three monitoring periods. Participants also rated their level of effortful control both before and after the thought suppression task. Results were not generally consistent with those found in previous study examining resting HRV and thought suppression ability. Cognitive load did not significant impact the effects of HRV and effortful control on thought suppression ability. Moreover, performance on the thought suppression task did not significantly affect self-reports of effortful control. Reasons for such replication failures are considered and future directions for research on the roles of self-regulatory capacity, cognitive load, and thought suppression ability are discussed.
