Several measures of associative patterns, cognitive styles, and attitudes toward self and others were obtained on 173 deaf adolescents and 178 normal controls. Results show reduced tendencies of the deaf to use evaluational concepts in association, but greater tendencies to devalue self and others. Deaf girls are much like deaf boys in associative and evaluational responses. Several possibilities for the study of implicit language processes in deaf and normal Ss are suggested.

32 representatives of the fields of clinical psychology, social work, psychiatry, and psychoanalysis discussed a set of 14 working papers. The 3 principal preparations for psychotherapeutic practice today are psychiatric residency, doctoral and postdoctoral programs in clinical psychology, and social work school, plus supervised work in a social work agency. Each has valuable contributions to make. Several types of pilot plans for improved training were proposed as being worth trying. Several kinds of potential institutional settings for such programs were considered. Regarding curriculum, "there was unanimous agreement that supervised experience in doing psychotherapy was of primary importance." (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献
