Experimental studies were conducted in two unions to examine the effects of perceptual variables–namely, reactance and intentionality attributions–on the intent to seek redress from management action. Participants responded to a series of vignettes, each of which described a management action (formal punishment, informal warning, promotion denial) taken against an employee. The vignettes varied systematically in terms of the perceived threat to worker freedom posed by the action and the degree to which the action was motivated by a dispositional rather than an environmental attribution. Both studies demonstrated that greater threat and dispositional attributions provoked stronger intent to file a grievance. Implications of the findings were discussed for investigating and screening grievances.  相似文献

KIRKPATRICK'S LEVELS OF TRAINING CRITERIA: THIRTY YEARS LATER   总被引:2,自引:0,他引:2  
Kirkpatrick's model (1959a, 1959b, 1960a, 1960b) of training evaluation criteria has had widespread and enduring popularity. This model proposed four "levels" of training evaluation criteria: reactions, learning, behavior, and results. Three problematic assumptions of the model may be identified: (1) The levels are arranged in ascending order of information provided. (2) The levels are causally linked. (3) The levels are positively intercorrelated. This article examines the validity of these assumptions, the frequency of each level in published evaluation studies, correlations from the literature in regard to Assumptions 2 and 3, and implications for the researcher and training manager.  相似文献

This field study used the Job Feedback Survey (Herold & Parsons, 1985) and performance data gathered from multiple sources to examine the relationship between the perceived organizational feedback environment and performance. Regression analyses indicated that, while holding the other feedback variables constant, feedback from supervisory and organizational sources was related to reported job performance while feedback from peers and self was not. Most of the unique variance in performance explained by feedback was also accounted for by feedback from organizational and supervisory sources. Negative expressions from organizational/supervisory sources (e.g., the supervisor expressing anger, the company communicating dissatisfaction with poor performance) were related to lower performance, and positive job changes initiated by these sources (e.g., increasing responsibility, assignment to special jobs) were related to higher performance. Higher performers did not receive more feedback than lower performers but did receive more total positive feedback. Supplemental issues, possible explanations, and implications of the findings are discussed.  相似文献

Literature since the last comprehensive review of research on the employment interview is summarized, and suggestions for future studies in this area are described. Major changes in findings regarding the validity of the interview, the impact of applicant sex, and the effect of interviewer characteristics/behavior on applicant reactions, as well as other issues, are reported. Contrary to the widely held belief that the interview has low validity, recent research indicates at least modest validity for this selection tool. Conversely, the effect of the campus interview on applicant reactions has been seriously questioned. Researchers are urged to examine several areas in social psychology, including the literature on attitudes-intentions-behavior, the elaboration likelihood model, and theories of discrimination to achieve greater understanding of the employment interview.  相似文献

This study examined the relations among physical fitness, body image, and locus of control. The Hall-Physical Fitness Test Profile, the Winstead and Cash Body Self-relations Questionnaire (BSRQ) and the Nowicki-Strickland Locus of Control Scale were administered to 243 freshmen. Women were significantly more positive about their physical appearance than men. Men were more positive about their physical fitness than women. Men were more physically fit than women. Men and women scoring in the internal direction viewed the physical fitness domain of their body image positively. Unlike men, internally oriented women had more positive perceptions of the health aspect of their body image. Physically fit men and women had positive attitudes toward the physical fitness component of their body image. Physically fit men differed from physically fit women in that men were more internal and held more positive attitudes toward the physical health dimension of their body images.  相似文献

This study compared normal developing children, aged 34 to 51 mo., on comprehension and production of relative dimensional adjectives using object manipulations in a close elicitation procedure and on Piagetian operational tests of conservation of continuous quantity, length, reversibility and seriation. Analysis indicated a significant difference on the expressive language performance of the transitional and the concrete operational children over the preoperational children, but no significant differences occurred between the first two groups. Children who performed better on seriation were significantly better on expressive language performance. Children classified as operational for length performed better on all language measures than those classified as nonoperational. Reversibility and conservation of a continuous quantity did not differentiate children.  相似文献

Many factors go into a choice of a therapeutic focus: the patient's psychopathology; the therapist's training, countertransference reactions, and ideological beliefs; and, importantly, a decision about what seems most amenable to treatment and change. As a theory, self psychology describes one aspect of the paranoid process; as such, it is an incomplete theory that complements rather than invalidates more classical theories. As a technique, however, it suggests a style and focus conducive to working with paranoid patients, one that is markedly supportive, nonconfrontational, yet also interpretive. In this context, it must be remembered how difficult it is to treat paranoid patients psychotherapeutically, much less to keep them in treatment. The strategies discussed above do not wholly replace other dynamic approaches (e.g., counterprojective techniques), nor are they universally applicable. Some patients may be more amenable than others. However, the techniques provide a very supportive framework that may help the therapist to be more available to and in contact with the paranoid patient. More broadly, this paper's application of self psychology to the theory and therapy of the paranoid disorders further illustrates the practical utility of this approach. Attention to the narcissistic developmental line, interpersonal selfobject relationships, intrapsychic conflicts and deficits, and empathic immersion in the patients's world are important adjuncts to the psychotherapy of paranoid patients. Rather than an either/or dichotomy, the principle of overdetermination suggests a both/and relationship between self psychology and traditional theory, such that the self psychological approach complements rather than contradicts the classical psychoanalytic theory. The vicissitudes of the self simply add another perspective or vantage point from which to understand and respond to the patient, one which has perhaps more applicability for preoedipally disordered patients.  相似文献

An organizational field study involving 95 civil service employees examined the ways these individuals coped with the stressful events of their daily living. Lazarus' cognitive-phenomenological analysis of psychological stress provided the theoretical framework. Subjects indicated on Lazarus' Ways of Coping Checklist those coping thoughts and actions used in the specific encounter described as stressful. As hypothesized, individuals experiencing higher diastolic blood pressure were more likely to cope using strategies characterized by wishful thinking, avoidance, and minimization of threat than were individuals exhibiting lower blood pressure. Implications from both an individual and organizational perspective are discussed.  相似文献

Trace mineral analysis of human hair was utilized to determine whether violent and nonviolent criminals could be differentiated on the basis of concentrations of levels of major and trace minerals. 40 violent and 40 nonviolent inmates from a prison population were selected for study. 27 mineral levels were analyzed and a discriminant function analysis correctly classified 86% of the violent and 78% of the nonviolent inmates. The results lent support to the hypothesis that significantly different levels of trace minerals could be found between the two groups.  相似文献
