These 3 studies investigated ways that high school boys vary in adaptation to different high school environments. The population was drawn from 2 all white, suburban-to-Detroit high schools with similarly sized enrollments and faculties, academic programs, structure of staff salaries, and demographic characteristics. One paper presents background data on the social environments of the 2 schools. Another compares, in a social situation not highly school related, the interpersonal styles of boys who differ in exploration preferences; considers the characteristics of social interaction for 10th grade boys; and attempts to capture the climate of the 2 schools as reflected in the atmosphere of the discussion groups. The 3rd paper presents the results of a self report study of 10th grade boys in a framework of person-environment interactions. The hypothesis here was that behavior, in this case perceptions, is the joint outcome of personal and environmental factors. This hypothesis was not supported by analyses of the variables reported here. (TA)
