Pre-test session. Before training, the POMS, EPQ and TTCT were administered in a group format. First, all the participants completed the POMS and then the EPQ. Second, to avoid interference between the two tasks a thirtyminute breakwas given after EPQ. The break included a 15-min rest and then 15-min explanation of the following TTCT tasks. Third, the TTCT was administered. The administration was performed blind by one psychology Ph.D. familiar with giving the POMS, EPQ and TTCT (Torrance & Ball, 1984; Torrance et al., 1981; Wu et al., 1981). Each participant completed the tests in a partition type desk.
