One criticism of modern behavior theory is that it has not been tested over a wide range of human differences. Without experimental evidence, one cannot be sure that manipulations which produce effects observable in college students, for example, will produce similar effects over a wide range of human differences. However, theories are often tested on college students. Consequently, there is a need for evidence that effects observed in the performance of college students may be observed in other groups. The main purpose of the present study is to test whether certain experimental variables produce similar effects over two individual difference variables. These individual difference variables are represented by samples of male and female college students and mental defectives. The experimental variables were effort per response, distribution of practice, and stage of practice. It is felt that performance patterns will be similar in all samples, but that the amount of treatment effects may not be the same. It is also felt that some basis is available for predicting the nature of these quantitative differences.
