Revision of the self-monitoring scale   总被引:14,自引:0,他引:14  
Snyder's (1974) Self-Monitoring Scale exhibits a stable factor structure that does not correspond to the five-component theoretical structure he presents. Sets of face-valid items that better approximate the theoretical structure are described. Correlations between these sets of items and measures of other constructs reveal that four of the five components are positively related to social anxiety. Effective social interaction is supposedly the high self-monitor's forte, and social anxiety appears to be incompatible with this. The correlational results therefore question the entire theory and indicate the need for a narrower definition of the construct. Adopting such a definition from Snyder's review article (1979), we present a 13-item Revised Self-Monitoring scale which measures only sensitivity to the expressive behavior of others and ability to modify self-presentation. A 20-item Concern for Appropriateness scale is also described. This scale measures 2 variables that are directly associated with social anxiety--cross-situational variability and attention to social comparison information. Both scales have acceptable internal consistency, and both yield 2 subscale scores as well as a total score. Prospective users of either scale are advised to treat the 3 scores separately.  相似文献

Twenty-two people who were presidential assassins and other similarly dangerous persons were assessed from information contained in Secret Service files and in published accounts. These documents were studied in order to determine common characteristics as well as other clues to the identification of potentially dangerous persons. Although there was no single pattern of development, there was a pattern of maladjustment that embraced common feelings of inadequacy or persecution, which led to similar patterns of behavior when attempting to resolve frustration. In practical terms, these profiles show:
  • 1 A systematic pattern of inadequacy in dealing with social, intellectual, and vocational challenges.
  • 2 A corresponding absence of any positive channel for achieving satisfaction or a sense of accomplishment.
In uniquely personal ways, each of these chronically frustrated individuals came to view his or her target either as the personification of the oppressive system, or as the agent through whom he or she could achieve “one great act,” or otherwise gain instant attention and status.  相似文献

Postpartum and lactational estrus: a comparative analysis in rodentia   总被引:1,自引:0,他引:1  
Virgin rodents exhibiting cycling estrus have traditionally been used for comparative studies of reproductive behavior. However estrus occurs in other life-history contexts, some of which differ from cycling estrus (CE) in that (a) the female is disposed to behave both maternally and sexually and (b) they result in litter overlap (i.e., the simultaneous gestation and lactation of two litters). In this report, two of these other modes of estrus are examined, with emphasis on their evolutionary and ecological implications. By means of a literature search of the order Rodentia, postpartum estrus (PPE) and lactational estrus (LE) were documented in 15 families, 71 genera, and 141 species. Analysis of these data showed that PPE and LE were nonrandomly distributed across taxa. They were statistically overrepresented in the family Cricetidae and underrepresented in squirrels (Sciuridae) and in pocket mice and kangaroo rats (Heteromyidae). Analysis of the phenotypes by which PPE and LE are achieved suggests important differences between them and CE in several parameters of female reproductive effort and breeding strategy, including maternal and copulatory behavior, optimal timing of litters, and hormonal control of heat and lactation.  相似文献

The author focuses on the trend in the family therapy field toward an expanded view of families in the context of their social environments. Within this broader eco-system perspective attention is given to individual-family-social network interrelations with implications for the family therapist.An earlier version of this paper was presented at the American Association for Marriage and Family Therapy, Dallas, Texas, October 29, 1982. Appreciation is expressed to Alice Lynn for her comments and suggestions on an earlier draft of this paper. The author has also benefitted from discussions with Douglas Sprenkle on paradigms and contexts.  相似文献

The intention of this study was to improve behavioral modeling's effectiveness by substituting managers for professional trainers and to evaluate the effect on 44 male supervisors using Kirkpatrick's four levels of evaluation: reaction, learning, behavior on the job, and performance. Twenty-two supervisors were trained with six behavior modeling modules and the effect was compared to a control group consisting of 22 supervisors. The research also examined the effects of trainees’ self-esteem and the perceived power of the trainers. The results showed that behavior modeling resulted in favorable reactions and an increase in learning, but did not produce behavior change on the job, or improved performance results. Power and self-esteem did not moderate the training effectiveness. The findings are compared with previous behavior modeling research. The discussion concludes with a recommendation for researchers to identify more complete theoretical models which explain behavioral change on the job (e.g., Maltz's theory of psycho-cybernetics) as opposed to relying solely on Bandura's social learning theory.  相似文献

Previous research on the factors which affect applicant decisions concerning jobs has focused on the effects of either job attributes or recruiting practices. The present study examined the simultaneous impact of job attributes and recruiting practices on the likelihood of job acceptance by actual job applicants. Path analysis revealed that job attributes but not recruiting practices influenced the likelihood of job acceptance by graduating college students (N= 200). Given that college students might be expected to be the job applicants most swayed by recruiting practices because of their lack of work experience, the results suggest that the emphasis placed on recruiting practices as determinants of applicant decisions may be overstated in the literature.  相似文献

This paper presents the results of an in-depth study of parameters characterizing sequenced saccadic eye movements for a group of dyslexic children and a comparative normal control group with ages in the range greater than 8.0 yr. and less than 13.0 yr. No parameters were statistically different for the two groups, which supports the findings of Brown, et al. and contradicts the findings of Pavlidis. Our results indicate that sequenced saccadic eye movements are not diagnostically useful for early detection of dyslexia.  相似文献
