The change in moral attitude due to discrimination of the degree of reality of thought is an unexplored potential effect of mindfulness training. In this article we examine whether the mindfulness training of novices reduces the defensive reaction to normative transgressions when the threatening thought is salient, that is, a thought that stands out regardless of the objective reality that threatens self-survival. To test the study hypotheses, we used a bifactorial design mindfulness training (pre vs. post) x threatened thought salience (low vs high) in a sample of 115 participants. The dependent variable (punishment of social norm transgression) was measured on two different occasions: (1) pre-training (T1), (2) after training (T2). One group receives training in mindfulness in the threatened thought salience low condition (N = 47), and a second group receives the same training in the threatened thought salience high condition (N = 38). A third group did not receive training in threatening thought salience high condition (N = 30). The results show that training mindfulness reduces moral punishment with high threatening thought salience and reduces moral judgment with low threatening thought salience. The shift in reactivity (punishment) is more representative of a MT effect than the shift in moral judgment (seriousness). Implications of the results and limitations of the study are also explored.
