The primary purpose of this study was to examine the effects on one child of observing another child receive direct social reinforcement. In the first part of the study, pairs of same-sex children worked on puzzles for three sessions spaced 2 to 3 days apart. One child was praised on a continuous schedule for performance, whereas the other received no praise. Although children who observed other children being praised increased their performance initially (as predicted by vicarious reinforcement and social comparison hypotheses), their performance decreased over time, reaching levels below their own baseline rates. In the second part of the study, intermittent praise delivered to the observing child was examined as a potential strategy to reverse the unexpected effects obtained in the first part of the study. Intermittent praise was found to be effective in reducing these effects and in producing enhanced performance. Individual data, as well as group data, are presented. Results are discussed in light of theoretical and applied issues related to the use of vicarious reinforcement in applied settings. 相似文献

Social approach to peers was evaluated as an intervention for isolate preschoolers. During baseline, confederate peers made few social approaches to the target subjects. Confederates greatly increased their rate of social approaches during the first intervention, decreased social approaches during a second baseline, and increased social approaches again in a second intervention phase. Increases in confederate social initiations immediately increased the frequency of subjects' positive social behavior. Additionally, five of six subjects showed an increase in their own positive social initiations during intervention periods. The results suggest that: (a) peers may be programmed to increase the positive social behaviors of their isolate classmates, and (b) remediating social deficits requires assessment and intervention specifically tailored to the individual child. 相似文献

A group of young children (mean age: 2.5 yr) were instructed to follow different requests by a teacher in a day-care setting. Experiment I verified that mean group instruction following was low (10%) despite the opportunity for “observational learning”, i.e., the group of 12 children could watch a nonreinforced adult comply with the teacher's request. In Experiment II, when positive consequences were provided contingent on the adult model's behavior, mean group instruction following was relatively unaffected (14%). When direct reinforcement was given to four peer models, each for several sessions, the individual performances of three of the four peer models was elevated (from 50% to 80%); however, the mean performance of the remaining nonreinforced children (N = 7) was only moderately affected (21%). When reinforcement contingencies were again changed, so that each group member was provided direct, but intermittent reinforcement, mean group performance increased substantially to levels of over 70%. Once instruction following was high, presentation of reinforcement only to one peer model sufficed to maintain performance whereas earlier, this same vicarious reinforcement procedure had failed to establish group compliance. The maintenance of instruction-following behavior when reinforcement was applied solely to one child was interpreted mainly in terms of a high resistance to extinction following a history of intermittent reinforcement rather than a “vicarious”- or “self”-reinforcement mechanism. Finally, removal and re-introduction of group intermittent reinforcement, respectively, lowered performance (to levels of 40%) and elevated (to levels of 65%) the group's performance. 相似文献

“Je suis en terrasse”: Political Violence,Civilizational Politics,and the Everyday Courage to Be 下载免费PDF全文
Christopher S. Browning 《Political psychology》2018,39(2):243-261
Following the attacks against the Paris offices of the satirical magazine Charlie Hebdo in January 2015 and the subsequent acts of political violence in Paris the following November, a number of memes spread swiftly across social media. Most notable of these were proclamations of “Je suis Charlie,” “Je suis Paris,” “Je suis en terrasse,” and tricolorizing one's Facebook profile page. Although there are various ways by which this phenomenon might be explained, this article argues that, at least for some people, they seem to have operated as key mechanisms by which individuals/society sought to reestablish what Tillich calls “the courage to be,” and which in more contemporary terminology might be labeled a sense of ontological security—the ability to go on in the face of what would otherwise be debilitating anxieties of existential dread. The article argues the memes did this through a number of mechanisms. These included establishing a sense of vicarious identification with the victims; embracing increased levels of danger and seeking to confront the question of mortality head on; reasserting a sense of community and home via the reinstantiation of everyday routines now ascribed with enhanced political and existential significance; and reaffirming a new civilizationally inflected self‐narrative. 相似文献

The potential impact on psychological well-being of working in the caring professions in the aftermath of trauma and disaster has been recognized for many years, with terms such as burnout, compassion fatigue, and vicarious traumatization coined to describe stress-related conditions. Although prevalent, these conditions do not affect all workers in the field. Various studies have investigated potential risk and protective factors. It is argued that the outcomes of this research should be used to guide practical interventions in the workplace designed to minimize stress-related problems. A framework that incorporates interventions at the primary, secondary, and tertiary prevention levels is outlined, and research investigating the efficacy of interventions at each of these levels is recommended. 相似文献

Intergroup vicarious retribution is the phenomenon whereby, after an out‐group member attacks an in‐group member, a member of the victim's group retaliates against a member of the perpetrator's group. This study examined the effect of expected cooperation from the in‐group on intergroup vicarious retribution through intra‐group reputation based on praise gain and exclusion avoidance. In the experiment, we conducted a one‐on‐one match in which, after participants learned that an out‐group member (as the winner) had imposed a fine on an in‐group member (as the loser) in a previous round, winning participants were allowed to impose an arbitrary fine on the other losing out‐group member. As a result, participants imposed a larger fine on their out‐group member opponent in retaliation when they were expected by in‐group members to cooperate than when such cooperation was not expected. Furthermore, participants regarded a fine as intra‐group cooperation. Since a path analysis revealed a mediating effect of praise gain, but no mediating effect of exclusion avoidance, expected cooperation from in‐group members facilitated vicarious retribution because those involved in retribution sought praise from other in‐group members. These findings suggest that the intra‐group reputation dynamics of expected cooperation and praise gain escalate intergroup conflict. 相似文献

The effect of nonverbal teacher approval (physical contact in the form of patting approvingly) delivered to target subjects on the attentive behavior of adjacent peers was examined in a special-education classroom. In a reversal design, two pairs of moderately retarded children were exposed to nonverbal approval, with only one subject in each pair receiving approval. In different phases, nonverbal approval was delivered alone or in conjunction with a verbal prompt directed to the adjacent peer or to the class as a whole. The prompt was designed to make salient the target subject's attentive behavior and the nonverbal reinforcing consequences that followed. Providing contingent nonverbal approval alone consistently altered attentive behavior of the target subjects but did not alter the attentive behavior of adjacent peers. However, accompanying nonverbal approval with a verbal prompt did increase attentive behavior of nonreinforced peers. 相似文献

Traumatic events are highly prevalent in South African society and psychologists who work with survivors of trauma have been identified as particularly at risk of being adversely affected by their work, and experiencing vicarious trauma. This study aimed to explore the experiences of a group of South African psychologists who work predominantly with trauma survivors. Individual semi-structured interviews were conducted with six psychologists (females = 67%). The predominant type of trauma encountered by participants in clinical practice was interpersonal trauma in the form of physical and sexual abuse (83%). Data were analysed using thematic analysis. All participants reported symptoms of vicarious trauma including disruption in cognitive schemas, symptoms characteristic of post-traumatic stress disorder, and somatic symptoms. Participants also reported vicarious post-traumatic growth including an enhanced sense of interpersonal connectedness and positive changes in their philosophy of life and self-perceptions. The findings serve to sensitise psychologists to the impact of working with trauma survivors so as to enhance the efficiency of psychological service delivery to traumatised populations. 相似文献

本研究采用"投注—反馈"的虚拟赌博游戏范式,通过2个实验分别检测个体在评价自己决策结果 (实验1)和观察他人决策结果 (实验2)过程中赌注大小(即参照点)对大脑活动的影响。结果发现:(1)体验自我决策结果时,输钱比赢钱诱发更负的FRN,仅有一个负反馈(-10元)表现出以赌注为界的分离,且相对效价一样的反馈值诱发的FRN差异不显著;(2)体验他人决策结果时,无论输赢,有赌注比无赌注诱发的FRN更负;而且相对效价相同的反馈值诱发的FRN差异不显著。据此可以认为,FRN一定程度上反映了以赌注为基准的主观标准对社会信息的评价判断:自我体验中的个体对损失的敏感度远高于收益;而替代体验中的个体更倾向于将"损失更多"看作一种负性结果。 相似文献
