In addition to the above approach, we also chose to perform an additional statistical analysis using a Bayesian framework. Within the Bayes framework it is possible to quantify the degree of evidence provided by the data for one hypothesis over another, including evidence for there being no difference, i.e. evidence for the null hypothesis (Kass & Raftery, 1995). For the experiment presented here our aim was to quantify the strength of the data in support of either (i) the hypothesis that there is a relationship between our personality factors (Cognitive Complexity & Blame Externalization) and inhibitory performance (PCIT), or (ii) for the null, that there are no personality related effects on inhibitory performance. This evidential value is presented as a Bayes Factor (BF) and is the ratio of the likelihood that the data support the experimental hypothesis over the null, with a ratio value of 3 taken as meaningful support for the hypothesis (Kass & Raftery, 1995). A Bayesian linear regression of PCIT with Cognitive Complexity yielded a BF of 86.72. We therefore have strong evidence in support of the hypothesis that Cognitive Complexity and PCIT are related. The remaining subscales of the BIS-11 showed no significant relationship to response inhibition in the PGNG
