This study aimed to investigate the evolution of cognitive intelligence, emotional intelligence, and spiritual intelligence and compare the development of the three types of intelligence from adolescence to old age. This research is cross-sectional developmental research design and descriptive method of a causal-comparative study. Participants in this study were 691 individuals living in Arak with an age range of 14-80 years were selected by random cluster sampling method, and answered Sohrabi and Naseri spiritual intelligence questionnaires, Bradbury-Graves Emotional Intelligence Questionnaire, and the adult version of the Raven’s Progressive Matrices Test. The results of data analysis by two-way analysis of variance showed a significant difference between different age groups in terms of spiritual intelligence, but this difference was not significant in cognitive and emotional intelligence. Also, the interaction effect of type of intelligence and age group was significant. It can be concluded that the developmental process of cognitive, spiritual, and emotional intelligence over time from adolescence to old age is not the same, and perhaps in the final stages of life with the loss and decline of one of these intelligences can be seen another increase to compensate for the deficiency to solve life problems.
