Abstract


This paper is about the study of digit symbol substitution test (i.e., to measure mental speed) between the adolescent (13-18 years ) and Middle adulthood (40-59 years). The main objectives of the present study is to find out the descriptive statistics of mental speed of adolescent and middle adulthood; to compare the statistically difference between adolescent and middle adulthood on mental speed; to compare the mean bar diagram on mental speed (i.e., time score in second) and error score. Trying to fulfill these objectives, the investigators randomly selected a sample of seventy-one participants (i.e., adolescence thirty-five; middle adulthood thirty six) from the normal Mizo Population residing in the Aizawl area. The age ranges are 13-18 years and 40-59 years respectively. Results are evaluated by using mean, standard deviation, one way analysis and mean bar diagram of both participants on mental speed. The result has indicated that mental speed i.e., time factor in second between adolescence and middle adulthood are found to be statistically significant but in error score, they are found to be insignificant. From the figure I and II, both time and error score, adolescence has less mean score as compared to middle adulthood.
