Relationships were investigated between EEG variables (alpha frequency, beta frequency, presence of slow waves) and anthropometric indices of androgen stimulation in males (male hair patterns, muscle development, body weight, chest circumference). In both samples (36 male college students and 25 male secondary school students) the anthropometric indices were associated with the presence of slow waves and slow alpha frequencies and with rapid beta frequencies. These results were interpreted, in conjunction with previous findings, as reflections of the simultaneous effects of androgens on physical development and central nervous functioning.
