ResultsIndependent samples t-test preliminary confirmed that experimental and control groups did not significantlydiffer on WCTT and TRI scores at pre-test (overall WCTT: t=.11, p=.91; overall TRI: t=1.14, p=.26). After the 6month laboratory both groups were readministered the WCTT and the TRI. The participants' performance on thesingle factors and on the total score of the two instruments used were compared by means of a 2x2 mixed ANOVAwith factors group (control or experimental) between subjects and time (pre-test or post-test) within subjects.Regarding the overall score as well as the “complexity” and “risk taking” factors of the WCTT, the main effects ofgroup and time, and their interaction, were not significant (F
