The main aim was to quantity the differences on reminiscence in terms of intelligence. In addition, it aimed to find out the difference on psychomotor reminiscence in terms of sex (male and female), length of work period and rest periods. 

The hypothesis of the study were: 1) Gifted subjects will show greatest reminiscence followed by normals while the least reminiscence will be shown by the retarded subjects. (2) Males will be superior to females on reminiscence. (3) Longer work periods will yield more reminiscence in comparison to shorter work periods. (4) Longer rest periods will yield more reminiscence in comparison to shorter work periods.

The sample consisted of 240 students of age group 12 – 15 years from schools of Chandigarh and Panchkula.  

Standard Progressive Matrices by J. C. Raven, and Coloured Progressive Matrices by Raven were used for data collection. 

The research was Experimental in nature. Two Work Periods (8 Minutes and 10 Minutes) and two rest Periods (1 Minutes and 2 Minutes) were used in this study. 

The findings of the study were: (1) Intelligence was found to be a significant determiner of reminiscence for all the three tasks. (2) Sex emerged as insignificant determiner of reminiscence on the entire three tasks. Length of work period was found to be significant determiner of reminiscence on letter cancellation task whereas it emerged to be an insignificant determiner of reminiscence on card – sorting and mirror tracing task. (3) The length of rest period emerged as a significant determiner of reminiscence for letter cancellation task only whereas it emerged to be insignificant for card – sorting and mirror tracing task. (4) The two factors interaction of intelligence and sex in letter cancellation task was found to be significant.
