Contrast sensitivity was measured for 12 healthy young males while sober, after ingestion of an alcohol placebo, and after ingestion of alcohol (95% grain alcohol; mean estimated blood alcohol level = .088%). Observations were made for both stationary gratings and gratings that traveled through a circular path and required pursuit eye movements. The significant alcohol-related reduction in contrast sensitivity was 2.6 times greater for moving (.29-log-unit reduction) than for stationary gratings (.11-log-unit reduction). The loss in contrast sensitivity for the moving gratings of high spatial frequency (12 cpd) was particularly severe (.37 log unit). Estimated blood alcohol level was correlated with the loss in contrast sensitivity for moving gratings (r = .61), but not with the loss for stationary gratings. Estimated blood alcohol level was strongly correlated with the difference between the loss in contrast sensitivity to moving and stationary gratings (r = .75). These results are consistent with reports that alcohol consumption degrades the ability to make pursuit eye movements. Subjects’ perceived intoxication level was not a reliable predictor of any index of visual performance.  相似文献

The aim of this paper is to demonstrate how object relations theory can be used to understand and regulate interpersonal conflict in group psychotherapy. Such concepts as projective identification, intersubjectivity and the analytic third are used to describe how conflict emerges in group psychotherapy and how it can be worked through. Case material is also provided to illustrate concepts and techniques in promoting a group's transition from a paranoid/schizoid to a depressive position. Positive aspects of the concept of projective identification are discussed including its use as a form of communication, a method of reducing anxiety and reintegrating previously dangerous and threatening aspects of the self.The paper was funded by Evan F.

The purpose of this article is to help counselors modify basic adult interviewing skills, often the focus of the skill development component in counselor education programs, for more effective application with elementary-age children. In particular, 4 specific areas regarding counseling skills are presented: (a) establishing the appropriate physical environment, (b) building trust, (c) maintaining the counselor's facilitative attitude, and (d) using questions appropriately. Recommendations on how these skills can be modified are also discussed.  相似文献

Abstract— People typically provide higher similarity ratings in response to the question "How similar is the typical preppie to you?" than to the question "How similar are you to the typical preppie?" Observed asymmetries in comparisons of the self and person prototypes have been offered as evidence that the self-concept acts as a habitual reference point in social judgment However, such a task does not test the habitual placement of a concept in the referent position of a comparison. In this study, participants judged the similarity between the self and person prototypes in response to linguistic (forced directional) queries or to spatial (nonforced) queries in which the self was positioned above or below the person concept Participants also rated pairs of familiar and unfamiliar countries in a similar manner, to replicate and extend the work of Tversky (1977) Expected asymmetries were observed in forced comparisons. The self and the familiar country were seen as more similar to other people and less familiar countries, respectively, when the former concepts served as the referent of a comparison than when they served as the subject Asymmetries were not observed in the nonforced conditions, and mean similarity in these conditions was of the same magnitude as in the forced condition in which the more familiar stimulus was the referent of the comparison. This result provides the first direct evidence that the self serves as a habitual referent in similarity judgments  相似文献

My concerns about Rational Emotive Behavior Therapy (REBT) began over a decade ago. I find its concepts lack adequate and consistent definitions, its distinctive hypotheses are not confirmed by empirical data and are untestable, and its scientific foundations fall outside mainstream psychology. Contrary to what it claims, its practice and philosophy are not consisten with the use of reason in psychotherapy. These criticisms are discussed and documented. Practitioners may not be aware of the unsubstantiated claims and theoretical assumptions inherent in REBT, and that they adopt these assumptions when practicing REBT.  相似文献

This paper demonstrates that the positiveness and negativeness of letters of acceptance and rejection from companies have an impact on company image, self-concept of recipient, and reported future intentions of potential recruits. The implication for employers writing letters of acceptance and rejection is that they should communicate with prospective recruits in a positive manner no matter what the letter's message. Positive rejection letters can mitigate effects of rejection and negative acceptance letters can impair the positiveness of acceptance.This research was partially supported by Grant #82037 from the Purdue Agricultural Research Station.

This study investigated the prevalence of traumatic brain injury (TBI) in an inpatient psychiatric population. We hypothesized increased prevalence of TBI relative to the general population due to a variety of risk factors observed in psychiatric patients. One hundred (mean age = 34) psychiatric inpatients completed the revised Head Injury Questionnaire. Chart review of 17 subjects reporting injuries established whether injuries were documented in medical records. Sixty-eight percent of this psychiatric population reported one or more injuries in which they were unconscious or dazed. This number is higher than the prevalence in the general population. Injuries were generally of mild to moderate severity; multiple injuries were common. Chart review of 17 subjects reporting TBI indicated that histories of TBI had not been noted in the medical record. Finally, 63% of TBI subjects reported that their injury predated the onset of their psychiatric symptoms. These results suggest a possible role of TBI in psychiatric symptomatology and have implications for psychiatric treatment in this population.  相似文献
