Virtual reality exposure therapy and standard (in vivo) exposure therapy in the treatment of fear of flying 总被引:1,自引:1,他引:0
This controlled clinical trial tested virtual reality exposure (VRE) therapy for the fear of flying (FOF), a relatively new and innovative way to do exposure therapy, and compared it to standard (in vivo) exposure therapy (SE) and a wait list (WL) control with a 6- and 12-month follow-up. Eighty-three participants with FOF were randomly assigned to VRE, SE, or WL. Seventy-five participants, 25 per group, completed the study. Twenty-three WL participants completed randomly assigned treatment following the waiting period. Treatment consisted of 4 sessions of anxiety management training followed either by exposure to a virtual airplane (VRE) or an actual airplane at the airport (SE) conducted over 6 weeks. Results indicate that VRE was superior to WL on all measures, including willingness to fly on the posttreatment flight (76% for VRE and SE; 20% for WL). VRE and SE were essentially equivalent on standardized questionnaires, willingness to fly, anxiety ratings during the flight, self-ratings of improvement, and patient satisfaction with treatment. Follow-up assessments at 6 and 12 months indicated that treatment gains were maintained, with more than 70% of respondents from both groups reporting continued flying at follow-up. Based on these findings, the use of VRE in the treatment of FOF was supported in this controlled study, suggesting that experiences in the virtual world can change experiences in the real world. 相似文献

Why do people dislike art that they find meaningless? According to terror management theory, maintaining a basic meaningful view of reality is a key prerequisite for managing concerns about mortality. Therefore, mortality salience should decrease liking for apparently meaningless art, particularly among those predisposed to unambiguous knowledge. Accordingly, mortality salience diminished affection for modern art in Study 1, and this effect was shown in Study 2 to be specific to individuals with a high personal need for structure (PNS). In Studies 3 and 4, mortality salient high-PNS participants disliked modern art unless it was imbued with meaning, either by means of a title or a personal frame of reference induction. Discussion focused on the roles of meaninglessness, PNS, and art in terror management. 相似文献

In two experiments, we used rapid serial visual presentation tasks to examine the usefulness of color for the direct selection of visual information for perceptual encoding. The participants' task was to make a discrimination as to whether a target letter within a rapid sequence appeared in its upper- or lowercase version, and an advance cue indicated the color in which the target letter was most likely to occur. To maximize the usefulness of the cued color, in validly cued trials, we used sequences in which the target was the only item appearing in the cued color. In both experiments, accuracy was highest for validly cued trials. A cost-benefit analysis revealed a facilitory effect of valid cues and an inhibitory effect of invalid ones. These results support the idea that color cuing allows the direct selection of objects for further perceptual processing. 相似文献

Previous research indicates that mortality salience and creative behavior combine to increase feelings of guilt, presumably over the disruption to social connection elicited by the call for innovative expression. The present studies examined whether satiating assimilation motives by highlighting conformity to others reduces this effect (Study 1) and facilitates positive psychological engagement (Study 2). Study 1 used a 2 (conformity vs. neutral feedback)x2 (mortality salience vs. control)x2 (creative task vs. noncreative task) design and had participants complete a self-report measure of guilt. Study 2 used a 2 (mortality salience vs. control)x2 (other goal task vs. self-goal task) design, and after a creativity exercise, had participants complete measures of positive mood, vitality, and creative problem solving. Results indicated attending to assimilation needs reduced the elevated guilt that follows the juxtaposition of mortality salience and creative behavior and also increased a sense of positive engagement. Implications are briefly discussed. 相似文献

Why do women underperform under stereotype threat? Evidence for the role of negative thinking 总被引:1,自引:0,他引:1
This study investigated the role of negative thinking as a potential mediator of performance deficits under stereotype threat. After being assigned to a stereotype-threat or a no-threat condition, 60 female participants were asked to complete a difficult math task. Using the thought-listing technique, women under stereotype threat reported a higher number of negative thoughts specifically related to the test and to mathematics compared with women in the no-threat condition. Moreover, women under stereotype threat also showed a sharp decrease in performance that (a) was most pronounced in the second half of the test and (b) was mediated by the increase in negative thinking. 相似文献

SCADS: A Model of Children's Strategy Choices and Strategy Discoveries 总被引:12,自引:0,他引:12
Preschoolers show surprising competence in choosing adaptively among alternative strategies and in discovering new approaches. The SCADS computer simulation illustrates how simple processes can generate this impressive competence. The model's behavior parallels data on children's addition in at least eight ways: It uses diverse strategies over prolonged periods of time, makes adaptive choices among strategies, discovers the same strategies as children, discovers strategies in the same sequence as children, makes discoveries without trial and error, makes discoveries without having experienced failure, narrowly generalizes new approaches, and generalizes more broadly following challenging problems. SCADS thus indicates plausible sources of young children's surprising competence at strategy choice and strategy discovery. 相似文献

We evaluated the effects of functionally equivalent task designs and alternatives, as validated by motion study procedures, on dependent variables (nonadaptive responses, use of alternative, attempts at task, and completed attempts at task) relevant to performing a selected task. First, we evaluated the effects of functionally equivalent task designs on the dependent variables. Second, we evaluated the effects of an efficient functionally equivalent alternative on the variables. Third, we compared the effects of the efficient functionally equivalent alternative with a less efficient functionally equivalent alternative on the same variables. The results showed that the inefficient functionally equivalent task design occasioned higher rates of nonadaptive responses than the efficient functionally equivalent task design. The results also showed that the functionally equivalent task designs and alternatives competed within and across response classes to reduce nonadaptive responses. Mixed results were obtained in comparing the effects of the efficient versus the less efficient functionally equivalent alternatives. We provide evidence for extending the current concept of functional equivalence to include task design responses as well as alternative responses in functional equivalence training. 相似文献

Sociocultural expectations of attractiveness for women have been studied extensively, but little research has focused on this topic with males. Using the two most popular men's fashion magazines (GQand Esquire), this study examined article and advertisement content as well as male models' body sizes to determine the extent to which men have received messages from the media on how to behave (e.g., diet, exercise) and look over a 32 year period (i.e., 1960–1992). Linear trend analyses revealed that the number of messages concerning physical fitness and health have increased as has the general popularity of health and fitness activities. Messages concerning weight and beauty, however, have declined since the late 1970s. In spite of these changes, measures of male models' body sizes have not changed significantly since the 1960s. These findings are discussed in the context of the sociocultural approach to eating disorders and recommendations for future research are provided. 相似文献

A variety of procedures have been used to promote spontaneous requesting in persons with developmental disabilities. However, effective use of such procedures depends in part on identifying the stimuli that gained control of requests during intervention. In the present study, two adults with severe disabilities were taught to request a preferred food item with a modified gesture for “eat.” After learning to respond when the trainer held up an item, an assessment of stimulus control was conducted to determine if requests would occur spontaneously, that is, without the trainer having to offer the item. One learner displayed a number of spontaneous requests during the assessment. Natural maintaining contingencies were then introduced to maintain his spontaneous requests. The other learner made no spontaneous requests during the initial assessment, but subsequent tests revealed that he sometimes requested as the trainer was about to display the item. It thus appeared that both learners were responding at an earlier point in the trial sequence. The results suggest that an assessment of stimulus control may be helpful when selecting strategies to promote spontaneous requesting. 相似文献

Previous research has shown that reminding subjects of their mortality encourages negative reactions to others whose behaviour or attitudes deviate from the cultural worldview (e.g. Greenberg, Pyszczynski, Solomon, Rosenblatt, Veeder, Kirkland and Lyon 1990; Greenberg, Simon, Pyszczynski, Solomon and Chatel 1992; Rosenblatt, Greenberg, Solomon, Pyszczynski and Lyon 1989). According to terror management theory, these findings result from a heightened need for faith in the cultural worldview that is activated by reminders of one's mortality. Study I assessed the plausibility of an alternative explanation which posits that mortality salience simply primes individuals' values. Whereas mortality salience led to harsher bond recommendations for a prostitute, a procedure that directly focused subjects on their values did not. Studies 2 and 3 assessed the possibility that reminding subjects of any worrisome future concern would produce the same effect as a reminder of mortality. In both studies, mortality salience led to negative reactions to a deviant and had no effect on self-reported affect, whereas other worrisome thoughts had no effect on reactions to a deviant but did create negative affect. Thus, consistent with terror management theory, mortality salience effects seem to result exclusively from thoughts of death. 相似文献
