Validation of two Hand Test indices of aggressive behavior in an institutional setting

The purpose of this investigation was to determine the effectiveness of the Hand Test (Wagner, 1962/1983) in differentiating among mentally retarded adults placed in community housing versus those discharged from an institution due to violent and destructive behavior. Hand Test protocols of 24 mentally retarded adults who were discharged from an institution for violent and destructive behavior were compared with those of 12 mentally retarded adults who were placed in community housing, with regard to the presence of two indices of aggressive behavior (the acting-out score, AOS, and the movement response, ACT-MOV). Results indicated that 20 of the 24 residents discharged for aggressive behavior manifested one or more of the signs, whereas only 3 of the 12 residents discharged to a less restrictive environment exhibited one or more of the signs. The findings further demonstrate the usefulness of the Hand Test in predicting violent and destructive behavior in an institutional setting.     

Facioscapulohumeral neuromuscular syndromes--problems of differential and early diagnosis and genetic counseling

Among 20 kinships affected by facioscapulohumeral and scapulohumeroperoneal neuromuscular syndromes 6 probands with autosomal dominant transmission and 5 obviously sporadic cases revealed myopathic changes on biopsy and were classified to have facioscapulohumer (operone)al muscle dystrophies. 5 autosomal dominant cases and one sporadic case with neurogenic muscle changes and 3 other non-dystrophic phenocopies emphasize the necessity of muscle biopsy for nosological assignment. Definite correlations between mode of inheritance, clinical and morphological findings could not be found. Pathological ultrasound and EMG findings in parents and children of seemingly sporadic cases suggest to assume autosomal dominant inheritance with incomplete penterance in such cases.     

Toward an understanding of social consequences of “feminine immodesty” about personal achievements

Two studies examine the hypothesis that females who are immodest about their achievements are perceived more negatively than are males who are immodest. The assumptions that there are social consequences of immodesty, and that women and girls believe there to be such consequences, have been raised in self-presentational explanations of women's tendencies to undervaluate and underestimate their performances. This study provides a test of this assumption is a sample of 236 high school students and 144 teachers. Each judged the intelligence, personality, popularity, and adjustment of a very successful (hypothetical) high school student who was presented as male or female, mdoest or immodest. Two replications allowed this assumptions to be tested for diverse areas of success. Results showed consistent and negative social consequences of immodesty, which were, however, differentially worse for girls in only one of four tests. Other significant effects revealed that the characteristics of the judges was a factor. The findings are interpreted in the context of assumptions in both the popular culture and the research literature that feminine immodesty may be perceived differently than immodesty on the part of males. Directions for future research to elucidate these findings are offered.The help of Mr. W. Alden, Assistant Superintendent, and the teachers at Mt. Greylock High School is gratefully acknowledged. We would also like to thank the Massachusetts teachers who participated in the study during their annual convention, as well as the high school students who participated. This study was supported by research funds from the Bronfman Science Center, Williams College.     

Tracing the evolution of knowledge structures

The goal of the research described here is to understand the evolution of knowledge structures as novices learn to use text editors. Two groups of individuals were trained to use one of two text editing systems: the IBM Displaywriter and UCSD-Pascal. Individuals rated the similarity among pairs of editing commands before and after training. Before training, subjects’ similarity ratings are characterized by heavy reliance on natural language denotations of command names. After training, subjects’ similarity ratings are explainable in terms of a small set of identifiable properties of underlying knowledge structures that are typical of experts’ knowledge about a text editor. These properties reflect functional features of command actions, and the psychological salience of a property for a given individual is related to editing performance.     

Maximizing split-half reliability estimates for projective techniques

Hand Test data from comparable sets of clinical samples were analyzed for reliability using the usual odd-even split and then also calculating all possible (126) split-half combinations. Maximum stable reliabilities were obtained which were substantially superior to the odd-even method. It was concluded that projective tests are probably more internally reliable than has heretofore been reported.     

Comparison of WAIS and WAIS-R scaled scores for an outpatient clinic sample retested over extended intervals

High correlations were obtained between WAIS and WAIS-R scores for an outpatient clinic sample tested and retested over extended periods. While the WAIS-R scores were generally lower than the WAIS values, the decrements were slight, suggesting that a previously administered WAIS can serve as a good estimate of what might be obtained from a second administration of the WAIS-R for this type of sample.     

Quality circles in the United States: a conceptual reevaluation

Faced with industrial decline, American managers have begun searching for strategies for increasing productivity. Recent attention has focused on Japanese management practices, particularly on quality circles (QCs). Drawing upon social science research, this article evaluates the assumptions behind QCs implemented in the United States. The authors present a conceptual analysis that indicates possible reasons for the differing rates of success for QCs in Japan and the U.S. The article also makes suggestions for the effective implementation of American QCs.     

A possible association between HLA B-27 and vulnerability to schizophrenia

The frequency of HLA B-27 has been found to be increased in schizophrenic patients, especially in those with a positive family history of schizophrenia. In the present study, psychiatrically healthy arthropathic patients bearing HLA B-27 were found to have significantly higher P scores as compared to arthropathic patients without this antigen. Psychoticism could be seen as a trait of the personality at high-risk for schizophrenia. Thus, the present finding suggests an association between HLA B-27 and the genetic vulnerability to some forms of schizophrenia.
