Outcomes of an antihomophobia teaching unit for 130 high school students were evaluated in a pretest-posttest follow-up design, with gender and school type as independent variables. Dependent variables were cognition (Modified Attitudes Toward Homosexuality Scale; Price, 1982); homophobic guilt, homophobic anger, and delight (Affective Reactions to Homosexuality Scale; Van de Ven, Bornholt, & Bailey, in press); behavioral intentions (Homophobic Behavior of Students Scale; Van de Ven et al., in press); and short-story responses. Multivariate analyses of variance revealed that participants' anger (p < .05) and behavioral intentions (p < .0005) were significantly less homophobic at posttest and follow-up. Analyses of the cognition variable showed that hostility toward homosexuals was significantly reduced for girls (p < .0005) and initially for boys (p < .0005); however, boys reverted to previous levels of homophobia on this variable at 3-month follow-up. Similarly, analyses of the delight variable for students in single-sex schools showed that girls became less hostile (p < .05) and maintained their reduced levels of homophobia, whereas boys became less hostile initially (p < .05) but then regressed. The intervention had no effect on students' guilt and no effect on delight for coeducational students. Analysis of all participants' short-story content using sign tests indicated that the instruction had the desired effect (p < .005). However, only the female, coeducational school cohort yielded significant results (p < .05). The findings reinforce the importance of using multiple dependent measures of homophobic response and of collecting follow-up data. They also imply that extensions of the unit are warranted, especially in the absence of longer term impact for boys.  相似文献

This experiment investigated whether acquired signals for threat capture and hold visual attention. Cues that were presented in an exogenous attentional cueing task were emotionally modulated using a fear-conditioning paradigm. During acquisition, undergraduate students (55 women, 11 men) learned that one cue (CS+) of the attentional task was a signal for an aversive white noise burst (UCS, 100 dBA) and that another cue (CS?) signalled its nonoccurrence. In a subsequent extinction phase, no UCSs were presented anymore during the cueing task. Results indicated that during acquisition, the CS+ cues strongly captured and held visual attention in comparison with the CS? cues, and that these effects diminished during extinction.  相似文献

Negative emotions increase self-focused attention, a core feature of depression and anxiety-related disorders. However, the cognitive mechanisms associated with the tendency to self-focus—and, conversely, with the ability to voluntarily disengage attentional resources from the self and direct them towards the external environment—remain poorly understood. Thus, this study aimed to examine whether a specific cognitive control mechanism that directs attention between self-generated thoughts and external information might moderate the relationship between dysphoria and maladaptive self-referential thinking. Results showed that dysphoria increases the frequency of rumination, self-blame, and catastrophising, especially for participants who have more difficulty in switching from self-generated thoughts to information provided by the environment. These results shed new light on the cognitive mechanisms underlying maladaptive self-referential thinking associated with dysphoria. More specifically, this specific cognitive mechanism might play a key role in the maintenance or amplification of a depressed mood.  相似文献

The notion that emotional expressions regulate social life by providing information is gaining popularity. Prior research on the effects of emotional expressions on observers’ inferential processes has focused mostly on inferences regarding the personality traits of the expresser, such as dominance and affiliation. We extend this line of research by exploring the possibility that emotional expressions shape observers’ construal of social situations. Across three vignette studies, an interaction partner's expressions of anger, compared to expressions of happiness or disappointment, led observers to construe hypothetical situations as less cooperative, both in dyads and groups. These effects occurred even when factual information regarding the cooperativeness or competitiveness of the situation was provided, attesting to the power of emotional expressions in shaping the construal of social situations. Results are discussed in relation to appraisal theory, reverse appraisals, emotions as social information theory, and the emergence of cooperation in groups and cultures.  相似文献

It has been shown that variability in the shape of emotion intensity profiles can be described in terms of three functional features, namely steepness at onset, skewness and number of peaks. However, it remains unclear which factors account for variability in each of these features. In the present study participants were asked to report intensity profiles of positive and negative emotions on a daily basis. Information was further collected regarding potential determinants of the functional features of the intensity profiles at three levels: trait-, episode-, and moment-determinants. Regarding steepness at onset, it was found for positive and negative emotions that intensity profiles have an especially explosive start when the eliciting stimulus is important, when the stimulus is still present during the beginning of the episode, and, in case of positive emotions, when the participant is an extravert. Concerning skewness, it was found for positive and negative emotions that profiles reach their peak more often towards the end when the eliciting stimulus is important, when the stimulus is absent during the beginning of the episode but present towards the end, and, in case of negative emotions, when the stimulus is uncontrollable. Regarding the number of peaks, it was found that profiles more often have multiple peaks when the eliciting stimulus is absent during the middle of the emotional episode.  相似文献

Employees in the twenty-first century must be equipped to effectively process information from print and online sources; yet, many students struggle with online research and comprehension skills, making them ill-prepared in college and careers. Utilizing a qualitative exploratory case study design, this study describes how a fourth-grade teacher developed her students’ online research and comprehension skills in small groups using the guided reading framework to frame her instruction. Key findings suggest that the teacher adapted many components of the guided reading framework to develop students’ online inquiry skills. Both the teacher and students experienced role changes and challenges related to the experience, yet students demonstrated high rates of engagement and collaboration. This paper provides a situated example of how a teacher adapted an existing instructional context in her classroom and implications for adapting other popular instructional context, frameworks, and models for supporting teachers in developing students’ digital literacy skills.  相似文献

Spirituality has mostly been studied in psychology as implied in the process of overcoming adversity, being triggered by negative experiences, and providing positive outcomes. By reversing this pathway, we investigated whether spirituality may also be triggered by self-transcendent positive emotions, which are elicited by stimuli appraised as demonstrating higher good and beauty. In two studies, elevation and/or admiration were induced using different methods. These emotions were compared to two control groups, a neutral state and a positive emotion (mirth). Self-transcendent positive emotions increased participants' spirituality (Studies 1 and 2), especially for the non-religious participants (Study 1). Two basic world assumptions, i.e., belief in life as meaningful (Study 1) and in the benevolence of others and the world (Study 2) mediated the effect of these emotions on spirituality. Spirituality should be understood not only as a coping strategy, but also as an upward spiralling pathway to and from self-transcendent positive emotions.  相似文献

In line with most models of emotion, research has shown that threatening information receives attentional priority over neutral information. Recently, it has been suggested that the degree to which participants divide their attention across the visual field (the attentional window) may modulate the extent to which salient objects are attentionally prioritised. In the current study, participants were required to identify a target inside one of a variable number of coloured circles. One colour (Conditioned Stimulus, CS +) was fear-conditioned using an electrocutaneous stimulus at tolerance level. This search task was combined with a go/no-go task that required participants to either divide attention across the visual field to create a broad attentional window (global group), or focus their attention on the fixation point to create a narrow attentional window (local group). The results showed that only in the global group was the CS + colour prioritised over the neutral colours, indicating that a broader attentional window leads to enhanced attentional prioritisation of threat. Implications for research on attentional bias to threat are discussed.  相似文献

Cognitive control is essential to flexible, goal-directed behavior under uncertainty, yet its underlying mechanisms are not clearly understood. Because attentional functions are known to allocate mental resources and prioritize the information to be processed, we propose that the attentional functions of alerting, orienting, and executive control and the interactions among them contribute to cognitive control in the service of uncertainty reduction. To test this hypothesis, we examined the relationship between cognitive control and attentional functions. We used the Majority Function Task (MFT) to manipulate uncertainty in order to evoke cognitive control along with the Revised Attention Network Test (ANT-R) to measure the efficiency and the interactions of attentional functions. A backwards, stepwise regression model revealed that performance on the MFT could be significantly predicted by attentional functions and their interactions as measured by the ANT-R. These results provide preliminary support for our theory that the attentional functions are involved in the implementation of cognitive control as required to reduce uncertainty, though further investigation is needed.  相似文献

Research has revealed that haptic perception of parallelity deviates from physical reality. Large and systematic deviations have been found in haptic parallelity matching most likely due to the influence of the hand-centered egocentric reference frame. Providing information that increases the influence of allocentric processing has been shown to improve performance on haptic matching. In this study allocentric processing was stimulated by providing informative vision in haptic matching tasks that were performed using hand- and arm-centered reference frames.  相似文献
