This study investigated the relationship among personality types, cognitive preference orientation, science achievement, intelligence, attitudes toward science and scientists, sex, and geographic area of eighth-grade science students using the following four instruments: (1) Myers-Briggs Type Indication (MBTI); (2) Cognitive Preference Examination II (CPE-II); (3) Science and Scientists Attitude Inventory (SASAI); and (4) Science Knowledge Test (SKT). The sample included 153 males and 130 females from urban, suburban, and rural locations. The MBTI results classified students according to the following dichotomies: extrovert-introvert, sensing-intuitive, thinking-feeling, and judging-perceiving. Cognitive preference groupings by a single preference resulted in memory, application, questioning and no preference categories, while grouping by two preferences resulted in memory-application, memory-questioning, application-questioning, and no preference categories. The investigation tested fourteen hypotheses. The relationship between MBTI sensing and intuitive types (in favor of intuitives) and between MBTI judging and perceiving types (in favor of perceiving) had a statistically significant relationship to intelligence. Statistical significance also existed between intelligence and attitudes toward science (but not scientists), and between science achievement and attitudes toward both science and scientists. The relationships of the other variables investigated did not yield significant results at the .001 level. (Author/GS)
