This study examined effects of explicitness of achievement goals and p
erceived probabilities of goal attainment on self-assessment. Subjects
were 251 undergraduate students. They were first asked, as measure of
explicitness of goals, if they hope to acquire good capability in sci
entific research, and second how they perceived their probabilities of
goal attainment. Self-assessment behavior was measured by task choice
and task preference for four tasks which differ in diagnosticity. The
main results were as follows. (a) The most diagnostic task was chosen
for more often by the subjects who both had an explicit goal and perc
eived the probability of goal attainment high, and those who didn't ha
ve an explicit goal and perceived the probability low. (b) On task pre
ference, the effects of goal explicitness and perceived probability we
re not found. These results suggest that self-assessment be done for f
uture self-enhancement.
