다국어 초록 (Multilingual Abstract)

This study has two major purposes : 1) Investigating the relationship between the Practical intelligence(PI) and the traditional intelligence test scores, and 2) the effect of the various variables influencing the PI. For it, the Everyday Problem Solving Inventory(EPSI) consisted of 12-problem situations, was constructed from three age groups : the young adult, the middle-aged and the elderly. The fluid intelligence was measured by the block design subscale and the crystallized intelligence by the vocabulary test subscale of the Korea Wechsler Intelligence Scale(KWIS) respectively. The subjects are 30 male college students(Mean age=21.50) and 30 male elderlys(Mean age=65.25). Each subject was requested to provide his alternatives to 12 problem situations. And each situation was rated on the dimensions of familiarity, controllability and anxiety level by Likert-type 7 point scale. Among three measures, there was a significant correlation between EPSI and crystallized intelligence scores only. And there was no significant age difference in EPSI scores, and only familiarity variable out of the three has significant correlation with the EPSI score. It can be concluded that PI does not decrease with age, but is determined by degree and quality of the experience. And there was little interaction between age and the domain of the problem, social or nonsocial.
