Relationships among optimism, coping styles, psychopathology, and counseling outcome 总被引:5,自引:1,他引:4
This study had two objectives. The first objective was to evaluate the discriminant validity of optimism by examining the relationships between optimism and coping styles, while controlling for psychopathology. The second objective was to evaluate how well optimism, coping styles, and psychopathology predicted counseling outcome. Participants consisted of 96 college students involved in individual counseling at a university counseling center located in the southeastern United States. Consistent with previous studies, optimism was positively correlated with task-oriented coping and social diversion (social support), and it was negatively correlated with emotion-oriented coping and avoidance (distraction) coping. However, after partially out psychopathology, only the relationship between optimism and task-oriented coping remained statistically different from zero. Both optimism and psychopathology predicted two measures of counseling outcome. In contrast, coping styles were not useful for predicting any of the outcome measures. Results provide limited support for the discriminant validity of optimism in general and the Life Orientation Test in particular. 相似文献

Stigma, social risk, and health policy: public attitudes toward HIV surveillance policies and the social construction of illness. 总被引:4,自引:0,他引:4
Data from a 1999 national telephone survey with a probability sample of English-speaking US adults (N=1,335) were used to assess how support for HIV surveillance policies is related to AIDS stigma and negative attitudes toward groups disproportionately affected by the epidemic. Anonymous reporting of HIV results to the government was supported by a margin of approximately 2-to-l, but name-based reporting was opposed 3-to-l. Compared with other respondents, supporters of name-based surveillance expressed significantly more negative feelings toward people with AIDS, gay men, lesbians, and injecting drug users. More than one third of all respondents reported that concerns about AIDS stigma would affect their own decision to be tested for HIV in the future. Implications for understanding the social construction of illness and for implementing effective HIV surveillance programs are discussed. 相似文献

The relationship between girls' media exposure and their development of eating disorder symptomatology was assessed. At Time 1 and Time 2 (16 months later), participants (N = 374; M age = 12.0) completed a questionnaire that assessed eating disorder sympto-matology and television and fashion magazine exposure. Girls were divided into 3 groups: increased, decreased, or no change in eating disorder symptomatology between Times 1 and 2. Girls with increased symptomatology had significantly increased their exposure to fashion magazines but decreased their number of hours of television viewing. Girls with decreased symptomatology had significantly decreased their exposure to both television and fashion magazines. 相似文献

The preceding article by Marc Bekoff reveals much about our current understanding of animal self‐consciousness and its implications. It also reveals how much more there is to be said and considered. This response briefly examines animal self‐consciousness from scientific, moral, and theological perspectives. As Bekoff emphasizes, self‐consciousness is not one thing but many. Consequently, our moral relationship to animals is not simply one based on a graded hierarchy of abilities. Furthermore, the complexity of animal self‐awareness can serve as stimulus for thinking about issues of theodicy and soteriology in a broader sense. 相似文献

Four studies demonstrated robust within‐ and between‐subject differences in willingness‐to‐pay (WTP) and willingness‐to‐accept (WTA) measures of the value of lottery tickets. Buyers and sellers attended to different numerical cues and interpreted the same numbers differently when setting these two kinds of monetary values. Affective influences appeared to guide the valuation process. Buyers with stronger positive feelings about owning a ticket were willing to pay more for a ticket; sellers with stronger negative feelings about no longer having a ticket required a greater minimum payment in exchange for their ticket. In addition, the WTA/WTP disparity tended to be greater for more affectively‐laden lottery tickets. The results suggest that WTA and WTP prices are constructed using salient numerical cues and affective feelings. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

In three experiments search termination decisions were examined as a function of response type (correct vs. incorrect) and confidence. It was found that the time between the last retrieved item and the decision to terminate search (exit latency) was related to the type of response and confidence in the last item retrieved. Participants were willing to search longer when the last retrieved item was a correct item vs. an incorrect item and when the confidence was high in the last retrieved item. It was also found that the number of errors retrieved during the recall period was related to search termination decisions such that the more errors retrieved, the more likely participants were to terminate the search. Finally, it was found that knowledge of overall search set size influenced the time needed to search for items, but did not influence search termination decisions. 相似文献

Hanley, Jin, Vanselow, and Hanratty (2014) described a functional analysis (FA) format that relied on a synthesis of multiple contingencies described by caregivers during open‐ended interviews. These interview‐informed synthesized contingency analyses (IISCA) provided effective baselines from which to develop socially validated treatments, but the synthesis precluded a precise understanding of individual contingencies influencing problem behavior. We conducted IISCAs and standard FAs (Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994) for nine children with autism to evaluate the likelihood of differentiation given a number of synthesized versus isolated variables. The IISCA was differentiated for all. The standard FA was differentiated for four; this number increased to six when we included precursors in the standard FA. We then compared treatments based on sets of differentiated analyses for four children. Treatment based on the IISCA was effective for all four; treatments based on the standard FA were effective for two. The role of synthesis in analysis is discussed. 相似文献

Hume's Principle, dear to neo-Logicists, maintains that equinumerosity is both necessary and sufficient for sameness of cardinal number. All the same, Whitehead demonstrated in Principia Mathematica's logic of relations (where non-homogeneous relations are allowed) that Cantor's power-class theorem entails that Hume's Principle admits of exceptions. Of course, Hume's Principle concerns cardinals and in Principia's ‘no-classes’ theory cardinals are not objects in Frege's sense. But this paper shows that the result applies as well to the theory of cardinal numbers as objects set out in Frege's Grundgesetze. Though Frege did not realize it, Cantor's power-theorem entails that Frege's cardinals as objects do not always obey Hume's Principle. 相似文献

Although implicit tests of positive and negative affect exist, implicit measures of distinct emotional states are scarce. Three experiments examined whether a novel implicit emotion-assessment task, the rating of emotion expressed in abstract images, would reveal distinct emotional states. In Experiment 1, participants exposed to a sadness-inducing story inferred more sadness, and less happiness, in abstract images. In Experiment 2, an anger-provoking interaction increased anger ratings. In Experiment 3, compared to neutral images, spider images increased fear ratings in spider-fearful participants but not in controls. In each experiment, the implicit task indicated elevated levels of the target emotion and did not indicate elevated levels of non-target negative emotions; the task thus differentiated among emotional states of the same valence. Correlations also supported the convergent and discriminant validity of the implicit task. Supporting the possibility that heuristic processes underlie the ratings, group differences were stronger among those who responded relatively quickly. 相似文献

In our article, “Syntactic complexity effects in sentence production” (Scontras, Badecker, Shank, Lim, & Fedorenko, 2015 ), we reported two elicited production experiments and argued that there is a cost associated with planning and uttering syntactically complex, object‐extracted structures that contain a non‐local syntactic dependency. MacDonald et al. ( 2016 ) have argued that the results of our investigation provide little new information on the topic. We disagree. Examining the production of subject versus object extractions in two constructions across two experimental paradigms—relative clauses in Experiment 1 and wh‐questions in Experiment 2—we found a strikingly similar pattern: reliable differences in latency and word durations, as well as in rates of disfluencies, signaling a greater cost associated with planning and uttering the syntactically more complex object extractions. MacDonald et al. reject that interpretation, namely that the differences we observed in the production of subject versus object extractions demonstrate asymmetric production difficulties. Here we address the concerns they raise by clarifying confusion and presenting novel experimental evidence in support of our original claims. 相似文献
