This study examines how gender is related to self-evaluations of information to discuss current social and political issues. The sample is one of predominantly white (96%) college graduates. Using alumni samples, we look at how members of four classes that span 20 years evaluate their knowledge to hold conversations on a variety of public affairs issues ranging from the Strategic Defense Initiative to government funding of abortion. We find gender differences, with men perceiving themselves more knowledgeable in conversations and women less so. We raise the possibility that they are “doing gender.” The implications of these findings are explored. 相似文献

A series of experiments on intersensory facilitation demonstrates that non-informative sound of low to moderate intensity (30/80 dB) facilitates the reaction to a visual stimulus. By manipulating the preprocessing and perceptual stages of the visual signals, it appears that auditory intensity reduces choice reaction time independently from the positive influence of the intensity and duration of the visual imperative signal, but interacts with the effect of stimulus degradation. Degraded stimuli take more profit of the sound than intact stimuli. Besides a short-term activation effect, originated by accessories of the auditory modality, on the motor adjustment stage (cf. Sanders 1983), the results suggest that the accessory influences the stage of feature extraction. 相似文献

Current interest in moral theorizing has been dominated by Kohlberg's cognitive-developmental view. Haan (1982) has challenged psychology's reliance on this rationalistic focus and has argued for a rethinking of morality's meaning in accord with everyday human experience. In light of this challenge, the present study gives both theoretical and empirical support to the advancement of a morality for everyday life. Specifically, a new measure called the Visions of Morality Scale (VMS) is reported. The VMS is sensitive to three dimensions which are necessary for an everyday morality: (1) a human constitutive component which is universally experienced by all human beings (empathy); (2) the inclusion of a behavioral component which reflects actual behavior (pro-social inclinations); and (3) a view of morality that is multilevel (private, interpersonal, and social). A brief sketch of the VMS is provided. Results are presented from a study of 181 high school students which relate the VMS to empathy and political orientation. Highly significant relationships were found among morality, political orientation, and empathy. In addition, results revealed numerous sex differences. Finally, the implications of an everyday morality are discussed. 相似文献

Previous research on homeless adolescents has largely ignored the distinction between those who have left home on their own volition (runaways), and those who have been forced to leave (throwaways). Fifty-two homeless adolescents in Brisbane, Australia, were assessed to compare male and female runaways and throwaways for social adjustment and symptomatology. Differences for social adjustment (antisocial tendencies and aggression) and symptomatology (social isolation and depression) were predicted. Results indicated that male runaways were significantly more hostile than male throwaways (p less than .001), and significantly more socially isolated than female runaways (p less than .025). Female throwaways, however, were significantly more hostile than male throwaways (p less than .025) and female runaways (p less than .025). Yet homeless males overall had a significantly stronger urge to act out hostility than homeless females (p less than .025). In addition, female throwaways were significantly more antisocial than male throwaways (p less than .001). There were no significant differences for depression. A theory of inner social control (Hirschi, 1969), postulating absence of bonding in earlier socialization, was supported. 相似文献

The size of the perceptual unit used in reading was addressed using the predesignated target paradigm. Sixteen subjects viewed the following stimuli in random order: the words tee, the, tie, and toe; the nonwords eet, eht, eit, and eot; and the letters e, h, i, and o. Subjects fixated on the location of the center letter and identified the letter as e, h, i, or o, alternatives which were known to them at the onset. A word superiority effect was obtained for the common word the but not for the less common words tee, tie, and toe. The word superiority effect was attributable to bias rather than discriminability: Subjects exhibited a bias to perceive the words in this experiment as the (i.e., there was a bias to perceive h in the t e stimulus presentations). These results suggest that the common word the is processed in reading units that are larger than the letter, and that the system is biased to perceive common rather than uncommon words in data-limited conditions. 相似文献

The effectiveness of an integrated treatment program utilizing cognitive-behavioral therapies for Panic Disorder was examined. Treatment was comprised of Cognitive Model of Panic-derived procedures, Cognitive Therapy and Applied Relaxation Training. Subjects meeting DSM-III-R criteria for Panic Disorder received thirteen 2.5-hr sessions of outpatient therapy in small groups, over a 12-week period. Subjects were given an extensive rationale of the etiology, development and maintenance of Panic Disorder, within the framework of the Cognitive Model of Panic, and controlled behavioral experiments in panic evocation to internal panicogenic cues, cognitive reappraisal of somatic and ideational cues, breathing retraining, Applied Relaxation Training and Cognitive Therapy to identify and remediate maladaptive beliefs and dysfunctional cognitive schemas. A comprehensive assessment battery was given at pre-mid-post-treatment which included measures of tripartite functioning, global severity, panic, fear, anxiety, depression and psychiatric symptomatology. Analyses indicated statistically significant improvements across all outcome domains. All subjects were free of spontaneous (uncued) panic attacks at post-treatment, and all met operationalized criteria for high endstate functioning. These findings are discussed, with recommendations for future research. 相似文献

In recent years, increasing evidence of sexual abuse of children has created a new field of medicolegal inquiry requiring a new expertise. In psychoanalysis, one of our specific tasks is to address the issues of diagnosis and of the pathogenic effect of sexual abuse as it is ultimately reflected in the intrapsychic dynamics of the developing ego. My hypothesis is that it may be possible to determine early in the treatment whether sexual abuse has taken place. The case of a two-and-three-quarters-year-old girl, suspected of having been molested by her father, is presented in depth. The evolution of material confirming the diagnosis is presented by way of documenting evidence of sexual abuse. Issues elaborating the difficulty in making the diagnosis are also explored. Finally, a synthesis of diagnostic considerations useful for arriving at a diagnosis of sexual abuse is presented in the hope that these factors will serve as diagnostic guidelines. 相似文献

This section draws attention to occupational stress and suggests ways in which psychologists can apply their knowledge of research methods and treatment to this issue. In this article, the past and present role of psychologists in occupational stress is examined and ways in which psychologists might play a more central role are proposed. Although industrial/organizational and health psychology are most obviously applicable to the study of workplace wellness, more focused attention and wider application of knowledge from other subspecialities are also examined. The need for increased attention to work and family; race, class, and gender; and training and public policy issues are also discussed. 相似文献

The fiery crash of a DC-10 at Sioux City, Iowa, on July 19, 1989, caused a crisis of major proportions, with attendant mental health needs. Various articles have described the need for psychological response teams in such crises. The present article provides practical guidelines for the preparation of a mental health disaster plan and for the coordination of a mental health team responding to a major air disaster. Such disasters can occur in any part of the country at any time. It is hoped that the suggestions in the present article will help teams that respond to future air disasters provide more rapid, effective, and efficient delivery of services to the survivors and their families, and the families of those who are killed. 相似文献
