Few studies have examined to what extent commonly held stereotypes reflect real intergroup differences in motivational goals. Taking a values perspective (Schwartz et al., 2012), the study examines value preferences among Jews and Russians in Russia, to assess the extent to which commonly held stereotypes reflect values of group members. Results showed that Jews reported substantially higher levels of universalism-tolerance, benevolence (both caring and dependability), and tradition values, and lower levels of power (both dominance and resources), and universalism-nature values, than Russians. Results indicated that the widespread Jewish stereotypes of power, achievement, and rootlessness/cosmopolitanism are ungrounded, while the stereotypes of liberalism and particularism are upheld by the reported differences in the value preferences between Jews and the majority population in Russia. The present study underscores the importance of value comparisons between ethnic minority and majority groups for understanding their motivational goals and thus fighting prejudices and discrimination.  相似文献

Air travel has been highlighted as a key environmental behaviour contributing to climate change. Given this, there is a surprising lack of theory-based research aimed at identifying factors that underpin motivation to reduce the number of flights taken. This study explored whether an extended theory of planned behaviour (TPB) model could be usefully applied to identify significant predictors of intentions to reduce the number of flights taken for leisure, holidays or to visit family or friends. Results supported the predictive utility of the TPB; the extended model was able to account for 52% of the variance in intentions over and above past behaviour and socio-demographic variables. Attitudes, subjective norms and behaviour-specific self-identity emerged as significant linear predictors. Findings support the utility of applying the TPB to air travel and suggest key variables which could be targeted in interventions to promote motivation to reduce the number of flights taken.  相似文献

Various analytical tools originally developed for theories of mechanistic explanation have recently been imported into the ongoing debate on the hypothesis of (extracerebrally) extended cognition (HEC). One such tool that appears particularly relevant to that debate is Craver’s mutual manipulability account of constitution (MM), most of all because it promises to settle the debate on experimental grounds. This paper investigates whether it is possible to deliver on that promise. We first find that, far from grounding an experimental evaluation of HEC, MM is conceptually incompatible with both internalist and externalist accounts of cognition. Next, we propose a suitable modification of MM, MM*, but it turns out that MM* presupposes rather than produces clarity on the extension of cognition. Moreover, subject to MM* the inference to constitution is radically empirically underdetermined. Finally, we argue that our results can be generalized and conclude that, for principled reasons, it is impossible to experimentally determine whether cognitive processes have extracerebral constituents. Determining the extension of cognition is an inherently pragmatic matter.  相似文献

Contributions to public goods are premised on the expectation that the collective will realize benefit in excess of the value of required contributions. However, past research has focused on public goods of fixed and known value, for which the added value of the produced public good is obvious. Research has largely ignored public goods whose eventual value is uncertain at the time contribution decisions are made. Two studies explored the effects of outcome variance on individuals’ contributions to a public good and their reasons for contributing. Contributions were negatively affected by loss prospects in the distribution of possible outcomes. Further, loss prospects directly discouraged contributions because of loss aversion, and indirectly discouraged contributions by fueling fears that others would not contribute. The negative effects of loss prospects were stronger when social uncertainty was low. Implications for social dilemma research and the effective management of collective action are discussed.  相似文献

Current controversies about the centrality of the Oedipus complex in psychoanalysis are difficult to resolve unless we address three obstacles in the way of rational examination. The first is that the Oedipus complex, Freud's "shibboleth" of psychoanalysis, is politically controversial. Second is the great difficulty in agreeing upon the definition and boundaries of the Oedipus complex, especially the necessary complexities introduced with the negative Oedipus complex, female sexuality, the nature of the preoedipal, and counteroedipal fantasies and actions. The third obstacle involves basic questions of psychoanalytic epistemology: our criteria for evidence to prove or disprove any particular proposition. I conclude that the awareness of these difficulties signifies a certain maturation in our thinking and that the complexity introduced by these obstacles can in time provide the groundwork for a set of formulations that is richer and closer to the complexities and ambiguities of the clinical situation.  相似文献

Switching between two tasks afforded by the same stimuli results in slower reactions and more errors on the first stimulus after the task changes. This “switch cost” is reduced, but not usually eliminated, by the opportunity to prepare for a task switch. While there is agreement that this preparation effect indexes a control process performed before the stimulus, the “residual” cost has been attributed to several sources: to a control process essential for task-set reconfiguration that can be carried out only after the stimulus onset, to probabilistic failure to engage in preparation prior to the stimulus, and to two kinds of priming from previous trials: positive priming of the now-irrelevant task set and inhibition of the now-relevant task-set. The main evidence for the carry-over of inhibition is the observation that it is easier to switch from the stronger to the weaker of a pair of tasks afforded by the stimulus than vice versa. We survey available data on interactions between task switching and three manipulations of relative task strength: pre-experimental experience, stimulus-response compatibility, and intra-experimental practice. We conclude that it is far from universally true that it is easier to switch to the weaker task. Either inhibition of the stronger task-set is a strategy used only in the special case of extreme inequality in strength, or its consequences for later performance may be masked by slower post-stimulus control operations for more complex tasks. Inhibitory priming may also be stimulus specific. Received: 31 March 1999 / Accepted: 23 July 1999  相似文献

Expectancy-value theory (EVT) is a dominant theory of human motivation. Historically, the Expectancy × Value interaction, in which motivation is high only if both expectancy and value are high, was central to EVT. However, the Expectancy × Value interaction mysteriously disappeared from published research more than 25 years ago. Using large representative samples of 15-year-olds (N = 398,750) from 57 diverse countries, we attempted to solve this mystery by testing Expectancy × Value interactions using latent-variable models with interactions. Expectancy (science self-concept), value (enjoyment of science), and the Expectancy × Value interaction all had statistically significant positive effects on both engagement in science activities and intentions of pursuing scientific careers; these results were similar for the total sample and for nearly all of the 57 countries considered separately. This study, apparently the strongest cross-national test of EVT ever undertaken, supports the generalizability of EVT predictions--including the "lost" Expectancy × Value interaction.  相似文献

Might it be morally wrong to procreate? David Benatar answers affirmatively in Better Never to Have Been, arguing that coming into existence is always a great harm. I counter this view in several ways. First, I argue against Benatar’s asserted asymmetry between harm and benefit—which would support the claim that any amount of harm in a human life would make it not worth starting—while questioning the significance of his distinction between a life worth starting and one worth continuing. I further contend that his understanding of hedonism and desire-fulfillment theories distorts their implications for the quality of human life; as for objective-list theories, I rebut his critique of their human-centered basis of evaluation. Notwithstanding this multi-tiered challenge to Benatar’s reasoning, I conclude with praise for his work and the intellectual virtues it embodies.  相似文献

Perceptual load hypothesis is proposed as a compromise between early and late theory of selective attention which states that the selection will operate early when the load on perception is high and it will operate late when the load on perception is low. Experimental findings have shown that the perceptual load hypothesis is too simplistic in nature as perceptual load is not the only determinant of selection processes. It is difficult to apply the load hypothesis to explain the occurrence of early selection in low load displays as well as the selection processes that operate on distractor and target stimuli that are a part of the same object. Factors like spatial proximity, cues that manipulate the spatial extent of attentional focus, salience of targets as well as the distractors, and perceptual grouping between the target and the distractors should be taken into account while explaining the selective control of attention. Thus, the perceptual load of the display is one such factor that affects selective attention and goal-directed behaviour, but it is not the only factor to affect the selective control of attention.  相似文献

Experiment 1 utilized a choice reaction time paradigm to examine whether advance information about the second component of a movement has similar effects upon movement initiation and execution as advance information about the first component. Four stimuli were assigned to four goal keys. Subjects responded with the index finger of their preferred hand. They had to press on of two intermediate keys before pressing the assigned stimulus goal key. Advance information signaled one pair of goal keys in such a way that either the first or the second movement component was unequivocally specified before the response signal appeared. Shorter reaction times resulted when the first component was precued. Further control conditions showed that advance information about the second movement component could not be utilized for movement preparation. Experiment 2 ruled out a perceptual interpretation of this effect. Experiment 3 showed that preparation time for two-component movements are longer than for one-component movements. The study permits the conclusions that speeded two-component movements are controlled by motor programs and that advance information about the first movement component is required before the second movement component can be programmed.  相似文献

This paper investigates how individuals deal with demands of social and economic change in the domains of work and family when opportunities for their mastery are unfavorable. Theoretical considerations and empirical research suggest that with unattainable goals and unmanageable demands motivational disengagement and self-protective cognitions bring about superior outcomes than continued goal striving. Building on research on developmental deadlines, this paper introduces the concept of developmental barriers to address socioeconomic conditions of severely constrained opportunities in certain geographical regions. Mixed-effects methods were used to model cross-level interactions between individual-level compensatory secondary control and regional-level opportunity structures in terms of social indicators for the economic prosperity and family friendliness. Results showed that disengagement was positively associated with general life satisfaction in regions that were economically devastated and has less than average services for families. In regions that were economically well off and family-friendly, the association was negative. Similar results were found for self-protection concerning domain-specific satisfaction with life. These findings suggest that compensatory secondary control can be an adaptive way of mastering a demand when primary control is not possible.  相似文献

Tinnitus is an experience of sound in the absence of an appropriate external source. A symptom that can accompany most central or peripheral dysfunctions of the auditory system, tinnitus can lead to significant distress, depression, anxiety, and decreases in life quality. This paper investigated the construct of psychological acceptance in a population of tinnitus patients. First, a cross-sectional study (N = 77) was conducted in which a tinnitus specific acceptance questionnaire was developed. Results showed that a Tinnitus Acceptance Questionnaire (TAQ) generated good internal consistency. A factor solution was derived with two factors: activity engagement and tinnitus supression. Second, a longitudinal study (N = 47) investigated the mediating role of acceptance on the relationship between tinnitus distress at baseline and tinnitus distress, anxiety, life quality, and depression at a 7-month follow-up. The results showed full mediation of activity engagement for depression and life quality at follow-up, partial mediation for tinnitus distress, and no mediation for anxiety. The role of acceptance in the negative impact of tinnitus distress merits further investigation.  相似文献

Two studies investigated the effects of manipulating team membership on the evaluation of a football player. We hypothesized that the evaluations of the same football player, Javier “Chicharito” Hernandez, would vary as a function of the categorization process. For study 1, participants were randomly assigned to one of three conditions: Manchester United, Mexican National team or control. Results showed that “Chicharito” obtained better evaluations when his membership to Manchester United was made salient. In study 2, participants were randomly assigned to one of two conditions: Manchester United and Mexican National team condition. We found support for the mediating role of team evaluation on the relationship between team membership and the evaluations of Chicharito. The theoretical and applied implications were discussed.  相似文献

Cognitive and behavioral interventions have been shown to be efficacious when used as an adjunct to pharmacotherapy for psychotic disorders. However, little previous research has investigated potential mediators of change in psychological treatments for psychosis. Acceptance and mindfulness-based therapies do not focus on directly reducing the psychotic symptoms themselves, but instead attempt to alter the patient's relationship to symptoms to decrease their negative impact. The current study examined this issue with data from a previously published randomized trial comparing brief treatment with Acceptance and Commitment Therapy (ACT) versus treatment as usual for hospitalized patients with psychotic symptoms (Gaudiano & Herbert, 2006a). Results showed that the believability of hallucinations at posttreatment statistically mediated the effect of treatment condition on hallucination-related distress. Hallucination frequency did not mediate outcome. The current study is a first step toward understanding the potential mechanisms of action in psychological treatments for psychosis.  相似文献

The National Institute of Mental Health (Bethesda, MD) reports that approximately 5.2 million Americans experience post-traumatic stress disorder (PTSD) each year. PTSD can be severely debilitating and diminish quality of life for patients and those who care for them. Studies have indicated that propranolol, a beta-blocker, reduces consolidation of emotional memory. When administered immediately after a psychic trauma, it is efficacious as a prophylactic for PTSD. Use of such memory-altering drugs raises important ethical concerns, including some futuristic dystopias put forth by the President's Council on Bioethics. We think that adequate informed consent should facilitate ethical research using propranolol and, if it proves efficacious, routine treatment. Clinical evidence from studies should certainly continue to evaluate realistic concerns about possible ill effects of diminishing memory. If memory-attenuating drugs prove effective, we believe that the most immediate social concern is the over-medicalization of bad memories, and its subsequent exploitation by the pharmaceutical industry.  相似文献

Two experiments (N=136) studied how 4- to 6-month-olds perceive a simple schematic event, seen as goal-directed action and reaction from 3 years of age. In our causal reaction event, a red square moved toward a blue square, stopping prior to contact. Blue began to move away before red stopped, so that both briefly moved simultaneously at a distance. Primarily, our study sought to determine from what age infants see the causal structure of this reaction event. In addition, we looked at whether this causal percept depends on an animate style of motion and whether it correlates with tasks assessing goal perception and goal-directed action. Infants saw either causal reactions or noncausal delayed control events in which blue started some time after red stopped. These events involved squares that moved either rigidly or nonrigidly in an apparently animate manner. After habituation to one of the four events, infants were tested on reversal of the habituation event. Spatiotemporal features reversed for all events, but causal roles changed only in reversed reactions. The 6-month-olds dishabituated significantly more to reversal of causal reaction events than to noncausal delay events, whereas younger infants reacted similarly to reversal of both. Thus, perceptual causality for reaction events emerges by 6 months of age, a younger age than previously reported but, crucially, the same age at which perceptual causality for launch events has emerged in prior research. On our second question, animate/inanimate motion had no effect at any age, nor did significant correlations emerge with our additional tasks assessing goal perception or goal-directed object retrieval. Available evidence, here and elsewhere, is as compatible with a view that infants initially see A affecting B, without differentiation into physical or psychological causality, as with the standard assumption of distinct physical/psychological causal perception.  相似文献

BackgroundThe transition out of elite sport can be distressing and many athletes experience a range of transition difficulties. However, the socio-cultural and discursive contexts which shape experiences remain largely unexplored in the transition literature.ObjectiveTo explore retirement and transition difficulties in a cultural context through an analysis of Australian newsprint media.Design and methodsA discursive analysis of 121 media articles reporting on post-retirement experiences of two Australian swimmers 7 and 5 years (respectively) into retirement. Data were analysed for repeated representation of transition difficulties, specifically how the cause of difficulties was attributed. The identities that were ascribed to athletes and what these functioned to accomplish were also examined.ResultsThe identities of both individuals were repeatedly constructed in terms of an athlete identity, to the exclusion of other identities. The responsibility for transition difficulties was depicted as located solely within the individual and, thereby, the sport setting and the broader socio-cultural context were overlooked.ConclusionsIn this cultural context (Australian news media), the repeated construction of limited identity positions for retired athletes and the construction of former athletes as the sole locus of transition difficulties have implications for their psychological well-being. Despite this, the role of the sporting and cultural context is rendered invisible in these accounts and more broadly, and interventions remain targeted at the individual level.  相似文献

In this article we offer a critical review of Matolino and Kwindingwi’s article “The end of ubuntu” in which they put forward their view, based on conditions in contemporary South Africa, that the philosophy of ubuntu is dead. In the main, we intend to uphold what we believe is the more plausible argument, as suggested by the title of Metz’s paper, “Just the beginning of ubuntu”. We argue that Matolino and Kwindingwi’s arrival at the conclusion that ubuntu is over is influenced by their point of departure, which appears to be established on the dubious pre-philosophic assumption that ubuntu, as a normative ethical theory, is a “narrative of return”. We further question their assertion that contemporary conditions in South Africa are the basis on which ubuntu moral theory should be dismantled. Matolino and Kwindingwi argue for the demise of ubuntu without supporting their position with convincing, logical reasons. We argue that ubuntu, insofar as it is a moral theory, is competitive and will ultimately prove to be a desirable ethic which could contribute positively towards developing moral character in the contemporary sociopolitical environment in parts of Africa. This article intends to explore the methodology and logic of the debate. However, in the pursuit of pure academic critique, we reject Metz’s allegation that the criticism by Matolino and Kwindingwi is ad hominem.  相似文献
