Problem-solving as a function of age, sex and the role appropriateness of the problem content

The purpose of this study was to investigate problem-solving ability as a function of age, sex and problem content by using 20 problems chosen from the problem-solving literature. The problems were administered without time limits to 8 males and 8 females in each of three age groups: 20--30, 40--50, 60--70. Analysis revealed that only age influenced performance with the middle-age group scoring significantly higher than the other groups. Analysis of the time required by each age group to solve the problems showed the young group required significantly less time than the other groups. Finally, the young group was seen to make more errors of commission while the older group made more errors of omission.
