A total of 189 male Vietnam veterans who were admitted to a specialized inpatient treatment program were evaluated using the Millon Clinical Multiphasic Personality Inventory to assess character styles. The veterans were assessed for Posttraumatic Stress Disorder by using a subscale of the Minnesota Multiphasic Personality Inventory (MMPI) and 72% of the patients were classified as having Posttraumatic Stress Disorder. The character styles of passive-aggressive, schizoid, avoidant, and borderline were significantly associated with these patients. The most common 2-point profile was passive-aggressive and avoidant (8-2 or 2-8) and was significantly related to the diagnosis. While drug and alcohol abuse were common problem areas for the entire sample, the profile of patients with Posttraumatic Stress was different from those of substance abusers. These results indicate that treating Vietnam veterans with this disorder requires adopting strategies which include a character style focus as well as a symptom focus.  相似文献

The subjects, 60 undergraduate students, were administered the Test of Nonverbal Intelligence (TONI) individually. The Shipley Institute of Living Scale was administered in small groups. A Pearson correlation of .56 was obtained for TONI Quotients, Forms A and B. TONI Quotients, Forms A and B, correlated with Shipley estimated WAIS--R IQ .50 and .46, respectively, and correlated to .71 and .64, with Shipley Total T scores, .52 and .44, respectively (corrected to .71 and .61), with Shipley Abstraction T scores, .51 and .42, respectively (corrected, .63 and .52), and with Shipley Vocabulary T scores .26 and .32, respectively (corrected to .63 and .52). TONI scores seem more closely related to Shipley Total and Abstraction scores than to Shipley Vocabulary.  相似文献

In a comparison of religious and nonreligious psychotherapists' perceptions of a portion of a psychotherapeutic session no significant differences were found on the Vanderbilt Psychotherapy Process Scale for four groups of therapists designated according to their scores on three religious questionnaires. While the results suggest attitudes toward religion are not reflected in therapists' practice of psychotherapy, limitations of the study indicate the need for more rigorous testing of this possibility.  相似文献

A single case study of a patient, D.M., with a lesion in the region of the right occipito-temporal gyrus is presented. D.M. had well-preserved language and general cognitive abilities. Colour discrimination, contrast sensitivity, gross depth perception, spatial localization, and motion appreciation were within normal limits.On the evaluation of perceptual abilities, he failed to identify two-dimensional shapes from stereoscopic vision, motion, and texture although in all cases he was able to identify the rough area subtended by the shape. These findings are considered in relation to the current anatomical-physiological functional models of vision and it is suggested that D.M.'s deficits provide evidence for the existence in man of a functional pathway involved in the computation of texture and fine aspects of shape, which is distinct from the pathways involved in motion and stereopsis processing on one hand and colour and coarse aspects of form on the other hand.  相似文献

The Priestley duality for Wajsberg algebras   总被引:1,自引:1,他引:0  
The Priestley duality for Wajsberg algebras is developed. The Wajsberg space is a De Morgan space endowed with a family of functions that are obtained in rather natural way.As a first application of this duality, a theorem about unicity of the structure is given.  相似文献

The subject of research coucerns causal relationships between variables of consuming home videos and television and different indicators of delinquency ("acceptance of social norms" (NORM-AK), "perceived risk of punishment" (DEL-RISK), "severity of negative consequences" (NEG-VAL), "acceptance of illegitimate means" (ILLEG-M)). Additionally, factors of influence external to media are taken into consideration which are connected with delinquency according to criminologic results, i.e. variables of communication and variables of the family life and the structure of the family. The model is tested by a sample of N = 305 male pupils of a Regensburg vocational school with methods analysing causality ("2-Stage-Least-Square" (2-SLS) and "Latent variables path analysis with partial least squares estimation" (LVPLS)). The 2-SLS-estimates largely confirm the causal relationships supposed in the model. The results are, three significantly positive indirect connections from the preference for violence of home videos to the main indicator of delinquency ILLEG-M (by way of the variables "consumption of home videos" put on the Index, NEG-VAL and DEL-RISK). The direct influence of the preference for violence on television on ILLEG-M is confirmed, whereas the direct path from the popularity of violent video films to ILLEG-M cannot be proved. The LVPLS-results essentially correspond to the relationship shown by 2-SLS; in addition the LVPLS-estimates also confirm direct causal relationships between the latent variables "consumption of violent video films" and "delinquency proneness".  相似文献

Eight experiments are reported that first establish and then explicate a serendipitous finding that judgments about whether digits are odd or even take longer for odd than for even digits. The slowing of judgments about odd digits is more pronounced when digit pairs or triples are used, but is still weakly present when a single digit must be classified. A similar effect is seen when judgments of nouns are based on whether the nouns are the names of living or dead objects. Nouns that name dead objects are judged more slowly than ones that name living objects. The concept "alive" is linguistically marked. Past research has shown that unmarked concepts are processed more rapidly than marked ones. The similarity in the pattern of results when digits and words are judged is used to argue that the slower judgments about odd digits are due to the fact that "odd" is a linguistically marked and "even" a linguistically unmarked concept.  相似文献

This case study concerns an 18-year-old bilingual girl who suffered a radiation lesion in the left (dominant) thalamic and temporal region when she was 4 years old. Language and memory assessment revealed deficits in auditory short-term memory, auditory word comprehension, nonword repetition, syntactic processing, word fluency, and confrontation naming tasks. Both languages (English and Dutch) were found to be affected in a similar manner, despite the fact that one language (English) was acquired before and the other (Dutch) after the period of lesion onset. Most of the deficits appear to be related to verbal (short-term) memory dysfunction. Several hypotheses of subcortical involvement in memory processes are discussed with reference to existing theories in this area.  相似文献

The effects of delayed presentation of a central theme on the comprehension and interpretation of narratives were investigated in adults with right and left hemisphere brain-damage and normal individuals. The performance of subgroups of the subjects with right and left hemisphere brain-damage also was examined. Right hemisphere brain-damaged groups with anterior and posterior lesions were significantly less accurate and identified significantly fewer central themes when central theme presentation was delayed until the end of a narrative than when the theme was presented at the beginning. Subjects with anterior right hemisphere brain-damage produced significantly more embellishments and confabulations than subjects with posterior damage and non-brain-damaged controls, regardless of theme condition. The performance of non-brain-damaged subjects and subjects with fluent and nonfluent aphasia was unaffected by the organization of the central theme in the narratives.  相似文献

Conclusion The legacy of the Swampscott conference 25 years ago is palpable. The scientific accomplishments have been substantial. The four agendas I have presented for the future development of the field depend upon psychologists as individuals and psychologists as participants in our departments, colleges, universities, professional societies, and peer review panels to reduce the constraints that limit the definition and study of psychological phenomena in community settings (Schneider, 1990). As these constraints are addressed, new social norms can be established to expand and diversify the research process. There are some explicit positive side effects that can occur. A new working social structure can be created for how universities and communities can be resources for each other.The four topics I have presented are agendas for keeping at the task of generating active and expanding scientific traditions. These topics when addressed in the context of collaboration with other disciplines and citizens can develop an empirical base of shared wisdom about how to carry out community psychology research. In these ways the benefits of community psychology research can become more empowering for the public and more and more systemic for the scholar.These comments were presented as an Invited Address at the 2nd annual meeting of the American Psychological Society, June 8, 1990, Dallas, Texas.The following persons took time to read and comment on earlier drafts of these comments. I have benefited very much from their appraisals. Eileen Altman, Daniel Cervone, Seeley Chandler-Kelly, Nancy Dassoff, Penny Foster-Fishman, Steve Goldston, Peter Graves, Kenneth Heller, Robert E.
