Adults and children seem to essentialize certain social categories. Three studies investigated whether, and how, exposure to ethnic diversity affects this bias. Participants were 516 kindergarten, 2nd grade, and 6th grade Israeli Jewish and Arab children attending regular (mono-cultural) or integrated schools. Study 1 revealed that exposure increased the salience of ethnicity, especially for Jewish children. Study 2 showed no differences among groups at kindergarten regarding the relevance of recalling a story character's ethnicity, but by 2nd grade, Jewish children attending integrated schools were the most likely to mention such information. Finally, Study 3 revealed that while all kindergarteners started off at a similar level of essentialism towards ethnicity, exposure affected Arab, but especially Jewish, children's essentialist beliefs. Moreover, there were negative correlations between the salience of and essentialism towards ethnicity. Thus, interethnic exposure alleviated children's essentialist bias towards ethnicity and did so via making children aware of, rather than blind to, ethnic categories.  相似文献

The present research reveals that when it comes to recalling and imagining failure in one's life, changing how one looks at the event can change its impact on well-being; however, the nature of the effect depends on an aspect of one's self-concept, namely, self-esteem. Five studies measured or manipulated the visual perspective (internal first-person vs. external third-person) individuals used to mentally image recalled or imagined personal failures. It has been proposed that imagery perspective determines whether people's reactions to an event are shaped bottom-up by concrete features of the event (first-person) or top-down by their self-concept (third-person; L. K. Libby & R. P. Eibach, 2011b). Evidence suggests that differences in the self-concepts of individuals with low and high self-esteem (LSEs and HSEs) are responsible for self-esteem differences in reaction to failure, leading LSEs to have more negative thoughts and feelings about themselves (e.g., M. H. Kernis, J. Brockner, & B. S. Frankel, 1989). Thus, the authors predicted, and found, that low self-esteem was associated with greater overgeneralization--operationalized as negativity in accessible self-knowledge and feelings of shame--only when participants had pictured failure from the third-person perspective and not from the first-person. Further, picturing failure from the third-person, rather than first-person, perspective, increased shame and the negativity of accessible knowledge among LSEs, whereas it decreased shame among HSEs. Results help to distinguish between different theoretical accounts of how imagery perspective functions and have implications for the study of top-down and bottom-up influences on self-judgment and emotion, as well as for the role of perspective and abstraction in coping.  相似文献

Science has needed a dispassionate valuation of psychoactive drugs, but a motivational analysis should be conducted with respect to long-term reward rather than reproductive fitness. Because of hyperbolic overvaluation of short-term rewards, an individual's valuation depends on the time she forms it and the times she will revisit it, sometimes making her best long-term interest lie in total abstinence.  相似文献

Seeing the talker improves the intelligibility of speech degraded by noise (a visual speech benefit). Given that talkers exaggerate spoken articulation in noise, this set of two experiments examined whether the visual speech benefit was greater for speech produced in noise than in quiet. We first examined the extent to which spoken articulation was exaggerated in noise by measuring the motion of face markers as four people uttered 10 sentences either in quiet or in babble-speech noise (these renditions were also filmed). The tracking results showed that articulated motion in speech produced in noise was greater than that produced in quiet and was more highly correlated with speech acoustics. Speech intelligibility was tested in a second experiment using a speech-perception-in-noise task under auditory-visual and auditory-only conditions. The results showed that the visual speech benefit was greater for speech recorded in noise than for speech recorded in quiet. Furthermore, the amount of articulatory movement was related to performance on the perception task, indicating that the enhanced gestures made when speaking in noise function to make speech more intelligible.  相似文献

The goal of this paper is to demonstrate a process by which qualitative and quantitative approaches are combined to reveal patterns in the data that are unlikely to be detected and confirmed by either method alone. Specifically, we take a sequential approach to combining qualitative and quantitative data to explore race differences in how mothers differentiate among their adult children. We began with a standard multivariate analysis examining race differences in mothers' differentiation among their adult children regarding emotional closeness and confiding. Finding no race differences in this analysis, we conducted an in-depth comparison of the Black and White mothers' narratives to determine whether there were underlying patterns that we had been unable to detect in our first analysis. Using this method, we found that Black mothers were substantially more likely than White mothers to emphasize interpersonal relationships within the family when describing differences among their children. In our final step, we developed a measure of familism based on the qualitative data and conducted a multivariate analysis to confirm the patterns revealed by the in-depth comparison of the mothers' narratives. We conclude that using such a sequential mixed methods approach to data analysis has the potential to shed new light on complex family relations.  相似文献

The Special Issue (June 2011) of the Journal of Clinical Psychology in Medical Settings titled Strengthening Our Soldiers (SOS) and Their Families: Contemporary Psychological Advances Applied to Wartime Problems revealed the following important concerns: 1) Who is at risk for psychological sequelae during and following service in the U.S. military? 2) How to deliver the best treatment for our soldiers and veterans with PTSD, Traumatic Brain Injury and Pain? 3) How to train the trainers? and 4) What are the current priorities for service delivery, research and funding? Assessment strategies and tools are provided to assist in identification of suicidal ideation and behaviors, alcohol abuse in spouses, posttraumatic stress disorders, depression, brain injuries and post-concussion syndrome, as well as positive growth experiences. Empirically validated Cognitive Processing and Prolonged Exposure treatments are described as are the empirical results already in evidence in our military populations. The innovative use of Virtual Reality and Telehealth applications is demonstrated in both army and naval settings for preparing and reducing trauma in affected soldiers. The Functional and Occupational Rehabilitation Treatment (FORT) Program and its role in returning function to injured soldiers with musculoskeletal pain and motion restrictions, while also leading to reductions of anxiety, depression and use of medical services, is described. A critique about providing service-research for children’s reactions to their parent’s deployments and family functioning during separation and reintegration is provided. The need for theoretical-empirical approaches to understanding pain-behavior, anxiety dysregulation as it impacts the brain function and structure is provided by experts in pain, neuropsychology, brain circuitry and anxiety management of multiple traumas. This final paper in SOS provides commentary on SOS and describes possible future implications of current psychological knowledge related to military personnel and their families.  相似文献

The aim of the present study was to expand the scope of category norm and typicality data to include verbs for use when investigating semantic memory in fields such as linguistics, psychology, and aphasiology. Two experiments were conducted. In the first, participants were asked to list verbs within 10 semantic categories (e.g. breaking, cleaning, cooking, etc.) and 10 noun categories (e.g. animals, fruit, tools, etc.). In the second experiment, participants were asked to rate the typicality of verbs within 8 of the previously investigated verb categories. Although participants listed fewer verbs in verb categories than nouns in noun categories, the overall patterns with regard to correlation analyses between production frequency, mean rank of responses, lexical frequency, and typicality were consistent with those observed in noun categories. These patterns are also consistent with those observed in previous research. Potential similarities and differences between nouns and verbs, as well as future applications of such data, are discussed.  相似文献

Although the use of semantic information about the world seems ubiquitous in every task we perform, it is not clear whether we rely on a scene’s semantic information to guide attention when searching for something in a specific scene context (e.g., keys in one’s living room). To address this question, we compared contribution of a scene’s semantic information (i.e., scene gist) versus learned spatial associations between objects and context. Using the flash-preview–moving-window paradigm Castelhano and Henderson (Journal of Experimental Psychology: Human Perception and Performance 33:753–763, 2007), participants searched for target objects that were placed in either consistent or inconsistent locations and were semantically consistent or inconsistent with the scene gist. The results showed that learned spatial associations were used to guide search even in inconsistent contexts, providing evidence that scene context can affect search performance without consistent scene gist information. We discuss the results in terms of hierarchical organization of top-down influences of scene context.  相似文献

Understanding the functionally relevant properties of objects is likely facilitated by learning with a critical role for past experience. However, current evidence is conflicting regarding the effect of prior object exposure on acquisition of object manipulation skills. This may be due to the influence of life history variables on the capacity to benefit from such experience. This study assessed effect of task-relevant object exposure on object-mediated problem-solving in 22 gibbons using a raking-in task. Despite not using tools habitually, 14 gibbons spontaneously used a rake to obtain a reward. Having prior experience with the rake in an unrewarded context did not improve learning efficiency in males. However, females benefitted significantly from the opportunity to interact with the rake before testing, with reduced latencies to solution compared to those with no previous exposure. These results reflect potential sex differences in approach to novelty that moderate the possible benefits of prior experience. Due to their relatively high energetic requirements, reproductively active females may be highly motivated to explore potential resources; however, increased investment in developing offspring could make them more guarded in their investigations. Previous exposure that allows females to learn of an object’s neutrality can offset this cautious exploration.  相似文献
