A sample of approximately 1,000 abstracts was obtained from Psychological Abstracts and keypunched for computer processing.

These terms were intercorrelated on the basis of their co-occurrence in documents, and the resulting matrix was factor analyzed. The factors were interpreted as representing classification categories. These were compared with, and shown to be similar to, the APA classification…
