The Ontario Test of Intrinsic Motivation (OTIM) was developed by Day (1970) to measure the traits of specific and diversive curiosity. According to Berlyne (1965) specific curiosity occurs when individuals engage in directed thinking, epistemic observation, or epistemic consultation. Berlyne (1965) has suggested that directed thinking accompanies both epistemic consultation and epistemic observation. The OTIM contains three scales, thinking, consultation, and observation, as measures of specific curiosity (Day, 1970). The most accessible index of specific curiosity is question-asking behaviour. Therefore, if the OTIM scales, consultation, observation, and thinking, are valid, they should be related to question-asking behaviour. Diversive curiosity is demonstrated whenever an individual engages in "autistic thinking," such as daydreaming or thinking about topics other than the one at hand (Berlyne, 1965). Day (1970) has included in the OTIM a diversive curiosity scale. There should be a high relationship between the diversive curiosity scale and the tendency to exhibit "autistic thinking." During the second class of a summer course in educational psychology, 34 Ss were administered the OTIM. During the seventh lecture Ss recorded the~r question-asking behaviour, and similarly, during the twelfth leccure their "autistic thinking." The product-moment intercorrelations were computed among the following measures: OTIM consultation, OTIM observation, OTIM thinking, OTIM diversive curiosity, questionasking behaviour, and "autistic thinking." There were moderate and significant positive correlations among the OTIM scales designed to measure specific curiosity (consultation X thinking, r = .63, p < .01; observation X thinking, r = .68, p < .01; observation X consultation, r = .74, p < .01). A significant positive correlation was obtained between scores on OTIM thinking and question-asking behaviour (r = .45, p < .01), supporting Berlyne's (1965) postulate that directed thinking underlies all forms of specific curiosity. Contrary to expectation scores on OTIM consultation and OTIM observation failed to correlate with questionasking behaviour. Scores on the OTIM diversive curiosity scale failed to correlate with any of the other measures, indicating that either Ss failed to identify their "autistic thinking" or the diversive curiosity scale does not measure the trait. The latter suggestion is perhaps tenable in that there are only 10 items in that scale.
