A) Positive correlation in the MT group (n = 26) between the cooperation index, which is computed as the within-subjects measure of the difference in percent acceptance rate of monetary offers from pre-intervention to post-intervention, and the delta value of each individuals' FFMQ score [post-MT > pre-MT]. This relationship was not evident in the CT group (R = − 0.21; p < 0.1).
B) Positive correlation between the FFMQ and daily home practice in the MT group. The average daily amounts of time spend on home exercises as measured by daily practice logs was 13.6 min (st.d. = 5.7) for the MT group. The CT group spent an average of 15.3 min (st.d. = 6.4) on home exercises as measured by daily practice logs, albeit the CT group did not display a significant correlation between FFMQ and home practice (R = 0.11; p < 0.3).
Note that daily practice logs from two subjects in the MT group were not collected due to technical issues and hence could not be included in this behavioral analysis (they were however both included in the neural analysis).
