This research examined the psychophysiology of emotional arousal anticipatory to potentially aversive and highly pleasant outcomes. Human brain reactions (event-related potentials) and body reactions (heart rate, skin conductance, the probe startle reflex) were assessed along motivational gradients determined by apparent distance from sites of potential punishment or reward. A predator-prey survival context was simulated using cues that signaled possible money rewards or possible losses; the cues appeared to loom progressively closer to the viewer, until a final step when a rapid key response could ensure reward or avoid a punishing loss. The observed anticipatory response patterns of heightened vigilance and physiological mobilization are consistent with the view that the physiology of emotion is founded on action dispositions that evolved in mammals to facilitate survival by dealing with threats or capturing life-sustaining rewards. 相似文献

The aim of the study was to assess the effects of visual aesthetic perception on event-related potentials (ERPs). Eight subjects assigned an aesthetic judgment (beautiful, neutral, or ugly) and a 10-step beauty estimation to the target stimuli, consisting of famous artistic pictures and geometric shapes. In a further task, the subjects performed a motor response to the previously judged pictures and geometric shapes. ERPs were recorded through 54 scalp electrodes during both tasks. The P3b amplitude was increased during the categorization of the geometric shapes compared to the artistic figures and during the vision of the beautiful targets preceding the motor response. The categorization of the aesthetic qualities of geometrical shapes seems to induce a higher level of attention, while a higher arousal variation was elicited by the recognition of beauty, in any form that was presented. 相似文献

Integrating mental health care in the primary care setting has been identified in the literature as a model for increasing
access to mental health services and has been associated with enhanced clinical and functional patient outcomes and higher
patient satisfaction. The Department of Veterans Affairs (VA), which operates the nation’s largest integrated health care
system, has taken a leadership role in creating a health care system in which mental health care is provided in the primary
care setting. This article examines VA’s efforts and progress to date in implementing evidence-based models of integrated
mental health services nationally in community based outpatient clinics, home based primary care, and outpatient primary clinics
at medical facilities. Psychology plays an important role in this progress, as part of an overall interdisciplinary effort,
in which all professions are crucially important and work together to promote the overall well-being of patients.
This article is based in part on a presentation by the first author at the 3rd National Conference of the Association of Psychologists
in Academic Health Centers (APAHC) in May of 2007 in Minneapolis, Minnesota. 相似文献

Anxiety sensitivity has been implicated as a risk factor for the development and maintenance of panic and other anxiety disorders. Although researchers have generally assumed that anxiety sensitivity is a dimensional, rather than categorical, variable, recent taxometric research has raised questions concerning the accuracy of this assumption. The present study examined the latent structure of anxiety sensitivity by applying four taxometric procedures (MAXEIG, MAXCOV, MAMBAC, and L-Mode) to data collected from two large nonclinical samples (n = 1,025 and n = 744) using two distinct measures of anxiety sensitivity (Anxiety Sensitivity Profile and Anxiety Sensitivity Index-Revised). In contrast to previous taxometric analyses of anxiety sensitivity, results of the present research provided convergent evidence for a latent anxiety sensitivity dimension. Several potential explanations for the discrepancy between these findings and those of previous research are discussed, as well as the implications of these findings for the conceptualization and measurement of anxiety sensitivity. 相似文献

HOW TO PREDICT FUTURE DURATION FROM PRESENT AGE 总被引:1,自引:0,他引:1
The physicist J. Richard Gott has given an argument which, if good, allows one to make accurate predictions for the future longevity of a process, based solely on its present age. We show that there are problems with some of the details of Gott's argument, but we defend the core thesis: in many circumstances, the greater the present age of a process, the more likely a longer future duration. 相似文献

This study investigated the effects of a dependent group-oriented contingency on the supportive and non-supportive fair play behaviors of 6th grade students engaged in volleyball games as part of their physical education instruction. Six students, one male and one female per class, from three classes, identified as demonstrating low incidences of supportive behaviors during volleyball games, were participants in this study. A multiple baseline across classes design was used to examine the data. During baseline few incidences of non-supportive behaviors occurred among all six students. However, the participants seldom displayed supportive behaviors during games (i.e., encouraged each other). Following the introduction of the dependent group contingency, supportive behaviors for all participants increased. Follow-up data, collected in an alternative setting, indicated variable maintenance. The results are discussed in the context of group contingencies and social behaviors in sports. 相似文献

Eye-tracking and gating experiments examined reference comprehension with fluent (Click on the red. . .) and disfluent (Click on [pause] thee uh red . . .) instructions while listeners viewed displays with 2 familiar (e.g., ice cream cones) and 2 unfamiliar objects (e.g., squiggly shapes). Disfluent instructions made unfamiliar objects more expected, which influenced listeners' on-line hypotheses from the onset of the color word. The unfamiliarity bias was sharply reduced by instructions that the speaker had object agnosia, and thus difficulty naming familiar objects (Experiment 2), but was not affected by intermittent sources of speaker distraction (beeps and construction noises; Experiments 3). The authors conclude that listeners can make situation-specific inferences about likely sources of disfluency, but there are some limitations to these attributions. 相似文献

In this study we examined the relationships among parental social supportive behaviors for children’s weekday and weekend
outdoor physical activity (OPA). Thirty-nine girls and 29 boys 8 to 11 years wore pedometers for 7 days. Sixty-five mothers
and 50 fathers responded to a social support questionnaire about OPA that was comprised of four dimensions: encouragement,
playing with, use of activity as family recreation, and watch. After controlling for age and sport participation, regression
analyses indicated that mothers’ use of activity as recreation was positively associated with girls’ weekday OPA. On the weekend,
fathers’ play with son was positively related to OPA. The effectiveness of family-based activity interventions depends on
when parents have opportunities to be present for their child’s activity and gender differences in the support provided. 相似文献

This article is a revised version of an invited plenary address given at the 39th Annual Conference of the American Association of Suicidology. The authors, a psychiatrist and a writer survivor, outline and summarize the different ways in which professionals and survivors come to an understanding of suicide. They explain how each group often exists independently and separate from the other--by cognitive and emotional dissonance, by private language, by psychological defenses and miscommunication--and call for dialog. They argue that both perspectives are essential to advance the science of suicidology and to give hope and meaning to those bereaved by suicide. 相似文献
