sarily be true. It is curious that the mean scores of T 2 for the pre-adolescent 

 group are so similar to the mean scores of T x for the adolescent group. 



Particular attention is called to the differences in the mean scores of 

 Ti and T 2 in each test from the pre-adolescent group to the adolescent group 

 to the post-adolescent group. There is a noticeable decrease in the mean 

 differences in these scores for all tests except consonance. Recalling the

mean difference of scores for the music degree students, each test shows the 

 positive variation in mean differences for all four groups according to the 

 order of pre-adolescent, adolescent, post-adolescent, and music degree 

 students (table 3). 



From such a descending series as these tests present from the pre- 

 adolescent group to the music degree students, one is inclined to interpret, 

 since there is less gain in retest scores as the ages increase, that some matura- 

 tion of capacities occurs up to the college prepared pupils. This maturation
