Mindfulness, Meditation, and Belief in Free Will/Determinism.

Two experiments investigated the influence of mindfulness, meditation, and type of induction (free will, determinism, or neutral) on affect and beliefs in free will/determinism. In Experiment 1, it was found that high mindful participants reported experiencing more positive affect and less negative affect than low mindful participants. In the determinism induction condition in Experiment 2, high mindful participants scored higher on free will beliefs after they meditated, whereas low mindful participants scored lower on free will beliefs after they meditated. So it would seem that mindfulness can have differential effects for high and low mindful individuals. It was also found that high mindful participants (depending on the task and induction condition) sometimes had longer reaction times than low mindful participants. This could be an indication of high mindful participants having a higher decision boundary for some tasks or simply an indication that high mindful participants enjoyed some tasks more than others (i.e., processing fluency). In addition, the internal consistency of the questionnaires was compared to the internal consistency found for those questionnaires in previous research.
