This paper examines how the presentation of computer-monitored performance information affects performance judgments. Two factors were examined: the performance pattern and the information format. In a computer simulation, subjects were responsible for evaluating the performance of a computer-monitored typist. They were assigned to one of three format conditions: a periodic, delayed, or summarized format. The pattern of the typist's performance was also varied: It either improved, worsened, or remained about the same during the simulation. Results indicate that performance pattern affected subjects' ratings of overall performance, performance quality, and performance consistency. Both factors influenced ratings of future performance and recall of specific performance information. Implications of these results for performance appraisals and computerized performance monitoring systems are discussed.  相似文献

We evaluated a means of increasing staff members' interactions with an individual with multiple disabilities through use of a voice output communication aid (VOCA). When activated, the VOCA allowed the individual to communicate through synthesized speech. Results indicated that staff members interacted with the individual more frequently when she had access to the VOCA, suggesting that VOCAs may represent an alternative to more traditional staff management programs for increasing interactions.  相似文献

This paper provides a phenomenological account of the writing of a young woman diagnosed with schizophrenia. The method of interpretation is to put ourselves in the place of the author drawing upon a combination of sympathy, reason, common-sense, experience, and “an intersubjective world, common to us all” (Schutz, 1945: 536). The result is the recognition of the person as also capable of putting herself in the place of others so as to understand their behavior. This “role-taking success” identifies the limits of the current sociological understanding of insanity's significance in social interaction as an instance of “role-taking failure” (Rosenberg, 1992). The very appearance of a piece of writing often permits one to recognize the presence of schizophrenia. The use of space may be quite bizarre. The varying margins betray the writer's changing mood. The letter may start at the bottom or side of the paper or very close to the top .... Capital letters and all letters are employed without any apparent rules, the former even in the middle of a word. (Bleuler, 1950: 159) What we want to understand is not something hidden behind the text, but something disclosed in front of it. (Ricoeur, 1971: 557) Why do we need an art of guessing? Why do we have to “construe” the meaning? Not only — as I tried to say a few years ago — because language is metaphorical and because the double meaning of metaphorical language requires an art of deciphering which tends to unfold the several layers of meaning.... [But also] because [a text] is not a mere sequence of sentences, all on an equal footing and separately understandable. A text is a whole, a totality. (Ricoeur, 1971: 548)  相似文献

Over the past decade, sport participation opportunities for females have increased dramatically. The purposes of this study were to compare perceptions of encouragement and support from socializing agents for: (a) female collegiate volleyball players competing during the 1979 and 1989 seasons, and (b) female collegiate athletes and female and male nonathletes. Female athletes (n= 345), female nonathletes (n= 128), and male nonathletes (n= 88) completed a questionnaire to assess significant others' influence on sport involvement during childhood, adolescence, and college years. Results indicated that interest and encouragement by parents, older siblings, and friends significantly increased for female athletes over the past 10 years during one or more developmental period. Discriminant analyses revealed that female athletes perceived stronger influences from mother, siblings, friends, and coaches than did male and female nonathletes. These results demonstrate that female athletes received greater social support than their peers a decade earlier, and these influences were significantly different than male and female nonathletes. This study was supported by a grant awarded to the first author by the Center for the Study of Women in Society, University of Oregon, Eugene.  相似文献

A mother's (prenatal) wish for a girl has, at times, been implicated as an etiological factor for boyhood femininity or its DSM-III-R diagnostic equivalent, the Gender Identity Disorder of Childhood. In one sample of 52 feminine and 52 nonclinical control boys from Los Angeles, the proportion of mothers who recalled a wish for a girl during the pregnancy did not differ significantly between groups (26.9% vs. 19.2%, respectively); however, in both groups, the maternal wish for a girl was significantly more common in sibships in which all of the proband's older siblings were male. In a second sample of 103 feminine boys from Toronto, the maternal wish for a girl was significantly higher than that found in the Los Angeles sample (43.7% vs. 26.9%), but a control group was not available; as in the Los Angeles sample, the maternal wish for a girl was significantly more common in sibships in which all of the proband's older siblings were male. Implications of these findings for further study of maternal influences on boyhood femininity are discussed.  相似文献

Aggressivity, inattention, hyperactivity, and impulsivity are cardinal dimensions of externalizing behavior problems of childhood. They are diagnostic and clinical features of childhood disorders, and are thought to be linked to the subsequent development of adult disorders such as substance abuse (SA). Little is known, however, about the convergent and discriminant validity of these four constructs. We used multiple measures to develop indices of aggressivity, inattention, hyperactivity, and impulsivity in a sample of 10- to 12-year-old boys (N=183) with and without a family history of SA. Data were taken from mother reports, child reports, teacher reports, and laboratory tasks. The study aims were (1) to test the convergent and discriminant validity of aggressivity, inattention, hyperactivity, and impulsivity; (2) to examine whether the data were consistent with a model specifying the four constructs as indicators of one superordinate factor; and (3) to differentiate boys with and without a family history of SA in construct scores. The results supported the convergent and discriminant validity of the four constructs. Although discriminable, the constructs covaried strongly and were consistent with a model specifying them as indicators of a single superordinate factor. Boys with a family history of substance abuse scored higher than control boys on aggressivity, inattention, and impulsivity scores, but the groups did not differ on hyperactivity scores. The results are discussed in terms of the role of childhood behavior problems in vulnerability to SA.This work was supported by the National Institute on Drug Abuse grant No. DA 05605.  相似文献

The value of attachment theory (Ainsworth, Blehar, Waters, & Wall, 1978) in describing parental relationships of late adolescents (N = 139) in trade and technical school programs was explored. Overall, students described positive attachments to parents, viewing them both as facilitating their autonomy and as being available as a source of emotional support. Male students who were attending schools farther away from their parents' homes described their parental attachments more positively than did students who attended schools closer to their parents' homes. Parental facilitation of autonomy was associated with self-reports of assertion for female students.  相似文献

Science and the Catholic church are both conservative, slow-to-change institutions. However, science has institutionalized procedures that ensure that ample amounts of criticism of currently accepted theories and methodologies will always be present. This arrangement of continuous conjectures and refutation in science ensures often slow but steady change. Because supporters often think of religions as trafficking in timeless truths, criticism of church beliefs and practices (even when intended to stimulate reflection and improvement) is frequently seen as being disloyal to the institution. Because of the growing crises caused by world overpopulation, I argue that the Catholic church's opposition to all artificial methods of birth control now lacks whatever moral force it might have had when originally promulgated. By highlighting theological perspectives that might be appropriate for the ecological realities of the 21st century, I hope the church will see the wisdom of reevaluating many of its positions in the light of rapidly approaching ecological imperatives.  相似文献

Pascalian wagers     
A person who does not have good intellectual reasons for believing in God can, depending on his probabilities and values for consequences of believing, have good practical reasons. Pascalian wagers founded on a variety of possible probability/value profiles are examined from a Bayesian perspective central to which is the idea that states and options are pragmatically reasonable only if they maximize subjective expected value. Attention is paid to problems posed by representations of values by Cantorian infinities. An appendix attends to Robinsonian hyperreals. Another appendix presents for comparison Newcomb's Problem and a problem in some ways like it suggested, I think, by ideas of John Calvin.  相似文献
