Abstract The investigation of leisure time activities through lifespan analysis has revealed the importance of such activities in the prediction of later life achievements and creative products. They may be more reliable predictors of future performance than IQs, creativity test scores or school achievement. In the present paper creative leisure time activities are considered to be creative products. A total of 192 fifteen year old academic secondary school students were involved in the study: Creative leisure time inventories were filled out, Raven Advanced Progressive Matrices administered, and school grades recorded. Results indicated that differences in leisure time inventory scores between boys and girls with high intellectual potential were smaller than those of students with average potential. Girls were overrepresented in the “schoolhouse gifted” group, but in the “creative gifted” and “intellectually gifted” groups the ratio of girls and boys was balanced.
