Multiple sense modalities can be stimulated conjointly by a physically complex item, such as a predator, and also by a physically solitary stimulus that acts on multiple receptor classes. As a prime example of this latter group, l-menthol from mint stimulates taste, smell, and several somatosensory submodalities. In 6 experiments that used a variety of psychometric techniques, the authors experimentally isolated the modality by which l-menthol is detected in the upper airways (the nose and mouth). Interestingly, absolute detection in both the nasal and oral cavities was based on olfaction and not stinging, cooling, or taste. These experiments illustrate how the sensory modality responsible for detecting a multimodal or multisensory stimulus can be psychophysically isolated.  相似文献

Sixty-two first and second grade students (28 boys, 34 girls) were exposed to one of three commercial videotapes in which either all-boys (traditional condition) or all-girls (nontraditional) were playing with a toy. Participants in the control condition were exposed to nontoy commercials. After exposure to one of the conditions participants performed a toy sort where they were asked if six toys, including the two manipulated toys, were for boys, girls, or both boys and girls. Participants in the nontraditional condition were more likely to report that the manipulated toys were for both boys and girls than were participants in the traditional condition, who were more likely to report that the manipulated toys were for boys. This effect was stronger for boys than for girls.  相似文献

The Russian Jewish intellectual, Chaim Zhitlovsky (1865–1943), a leading architect of secular Jewish culture and thought, was a central figure in the progressive Jewish intelligentsia of the late nineteenth and early twentieth century. In an essay written in 1927, Yidn un Yiddishkayt (Jews and Jewishness), he sought to define the secular essence of what he calls Yiddishkayt. This essay is not the first in Zhitlovskys long publicistic career in which he searches for new, secular definitions of Jewish identity and culture. But this essay differs, since it is marked by Zhitlovskys use of contemporary social scientific notions of race and racial traits to conceptualize what he believes constitutes Jewishness in a non-religious context, along with his adoption of the mystical Jewish concept of the pintele yid, the theory of an innate Jewishness embodied by a Jewish spark. Zhitlovskys desire to craft a truly secular theory of Jewish identity led him ironically to accept models of Jewish identity at odds with his stated larger vision. In turning to contemporary racial theory, as well as long nurtured mystical models of Yiddishkayt, Zhitlovsky reveals the wide range of ideological discourses that led him to innovative and controversial notions of modern Jewish identity.  相似文献

We examined cross-sectional and lagged effects of sexual harassment (SH) and generalized workplace harassment (GWH) on incidence of self-reported illness, injury, or assault in a sample of over 1,500 university employees. SH and GWH, but not other job stressors, were related to increased odds of illness, injury, or assault. This was true when SH, GWH, and illness, injury, or assault were measured at the same time point, as well as when SH and GWH were measured in year prior to illness, injury, or assault.The data presented here are part of an ongoing longitudinal study of workplace harassment conducted at the Department of Psychiatry of the University of Illinois at Chicago. This research was supported by the National Institute on Alcohol Abuse and Alcoholism (grants AA09989 and AA13332). Portions of this paper were presented at the annual meeting of the Society for Industrial and Organizational Psychology, April 2004, Chicago, Illinois. The data were collected by the Survey Research Laboratory at the University of Illinois at Chicago.  相似文献

This study examines the hypothesis that highly favorable outcome expectations promote weight loss and hinder weight maintenance. To investigate the effects of outcome expectations and satisfaction with treatment outcomes on weight loss, 349 adults were randomly assigned to 1 of 2 weight loss programs that emphasize either (a) an "optimistic" message, focusing exclusively on the positive aspects of weight loss, or (b) a "balanced" message, giving equal time to positive and negative aspects of weight loss. Participants changed their weight loss cognitions in response to the intervention, but there was no significant difference between the intervention treatment groups in short-term or long-term (18-month) weight loss. Independent of treatment message, positive outcome expectations and satisfaction were both associated with weight loss.  相似文献

The issue of suicide, including prevention, intervention, and postvention, continues to be a problem on college campuses. For this study, data concerning a variety of issues related to college student suicide were collected from 1,865 students at four different universities. Incidence, risk factors, and potential solutions are described, as well as implications for mental health professionals in university settings.  相似文献

Important progress in our understanding of the natural course of personality disorders (PDs) is documented in the articles for this special section. This progress could set the stage for ideas developed in the study of PDs to play a central role in research on psychopathology more broadly conceived. The Collaborative Longitudinal Personality Disorders Study (Skodol et al., this issue), the Children in the Community Study (Cohen, Crawford, Johnson, & Kasen, this issue), and the McLean Study of Adult Development (Zanarini, Frankenburg, Hennen, Reich, & Silk, this issue) reveal the importance of personality in understanding psychopathology, and point toward a dimensional approach to conceptualizing psychopathology that could also frame categorical clinical decision making processes.  相似文献

Fifteen children with selective mutism (SM), 15 children with anxiety disorders (AD) without selective mutism, and 15 children without anxiety disorders or selective mutism (CN) were compared to examine the relationship between selective mutism and anxiety. Data were collected from children (age 4–10 years), parents, teachers, and clinicians. Results indicated that children with SM closely resemble children with AD. All children with SM received a diagnosis of social anxiety disorder and 53% received a diagnosis for an additional anxiety disorder. In addition, the SM and AD groups differed substantially from controls with respect to parent- and teacher-rated internalizing behavior problems. No differences among the groups were found with respect to parent-and teacher-reported externalizing behavior problems. The results are consistent with prior research emphasizing the association between selective mutism and anxiety disorders, and suggest that selective mutism may be conceptualized, assessed, and treated as an anxiety-related problem.  相似文献

Examination of the available literature regarding the development of the MacArthur Competence Assessment Tool-Criminal Adjudication (MacCAT-CA) reveals 2 theoretical factor structures on which the MacCAT-CA was based: one in which 3 lower-order constructs are proposed (understanding, reasoning, appreciation) and one in which 2 higher-order constructs are proposed (competence to assist counsel and decisional competence). Confirmatory factor analyses were conducted with the MacCAT-CA's original normative sample (N = 729) to test both the relative fit of these 2 theoretical factor structures and models that combine the 2 factor structures. Analyses were also completed to examine the convergent and discriminant validity of the MacCAT-CA. Results are discussed in terms of the strengths and weaknesses of the nomothetic nature of the MacCAT-CA.  相似文献
