Heterogeneity in contribution levels within public goods games (PGGs) is indicative of individual self- or other-regarding preferences. Reward and punishment mechanisms have been demonstrated to affect contributions in the PGGs. This paper examines whether dispositional sensitivities to rewards and punishments (BIS and BAS) explain some behavioural heterogeneity in PGGs. Seventy-two participants took part in a sequential PGG, in which, prior to making a decision about contributing, participants received information about how much their co-players had donated, which was manipulated either as high or low. They also completed the Carver and White BIS/BAS scales. Participants contributed more when other members of their group contributed a high proportion of the initial endowment and less when others gave a low amount. When participants knew that their group members had contributed a high amount, BAS Reward Responsiveness was significantly negatively correlated with the contribution levels, while BIS-anxiety was positively related to a lower proportion of zero contributions. The findings are interpreted in relation to strategic responding in the PGGs. Motivational traits, such as those conceptualized in Reinforcement Sensitivity Theory, are proposed to underlie pro-social behavioural preferences. 相似文献

Psychopathy is associated with two extremities. On the one hand, psychopathic individuals lack any concern for social norms and they are severely poor in maintaining healthy social relationships. In addition, the ability of individuals with psychopathy to feel certain emotions such as empathy, guilt or fear is seriously compromised. In contrast to these deficits, some behaviors and tendencies are exaggerated in psychopathy. For instance, psychopathic individuals display higher than normal impulsivity, stimulation-seeking, aggression and risk-taking. There are indications in the literature that pro-social behavior, as well as the feelings of empathy, guilt and fear are mediated predominantly by regions within the right hemisphere (RH), whereas impulsivity, stimulation-seeking, aggression and risk-taking are linked primarily with left hemisphere (LH) activity. From a neurobiological perspective, it seems that psychopathy may be associated with an altered and imbalanced inter-hemispheric dynamics; a relatively hyperfunctioning LH and/or a hypofunctioning RH. Furthermore, within the psychopathic population, the RH hypofunctioning is more characteristic of primary psychopathy with its affective and interpersonal deficits, while the LH hyperfunctioning is most typical of the secondary psychopathy which is marked by impulsivity and antisocial style. 相似文献

This investigation used a daily diary methodology to examine goal revision and effort allocation processes over a single, 2-weeks performance episode in which individuals prepared for a course exam. Growth curve modeling revealed that daily goal exhibited a curvilinear trend in which it was stable and relatively high at the beginning of the time period, but rapidly declined as the exam approached. Daily effort exhibited a trend opposite of the goal trend, remaining low and relatively stable at the beginning and increasingly rapidly as the exam approached. Current mood predicted daily goal revision, with positive mood being positively related to goal revision and negative mood being negatively related to goal revision. The traits of behavioral activation system (BAS) sensitivity and behavioral inhibition system (BIS) sensitivity moderated within-person relationships of positive and negative mood with goal revision. Simultaneous and lagged relationships among mood, goals, and daily effort were also examined. 相似文献

Influence of caregiver burden on the association between daily fluctuations in pleasant activities and mood: A daily diary analysis 总被引:1,自引:0,他引:1
Much research has focused on behavioral activation and its effect on depression, but less is known about the effects of leisure activities on the two distinct affective domains of depression: positive affect (PA) and negative affect (NA). Furthermore, individual factors (i.e., stress level) may moderate the impact of behavioral activation on affect. The present study utilized a daily diary approach to examine the moderating effect of stress on the relationship between leisure satisfaction and both PA and NA. Twenty-five dementia caregivers completed activity and affect measures four times daily for 14 days. Results were analyzed using multilevel modeling, an approach that considers intra-individual differences in activity and affect over time. Results supported the hypothesis that caregivers with higher burden display a stronger association between leisure satisfaction and affect than caregivers with lower burden. Specifically, caregivers with higher burden had a stronger positive relationship between leisure satisfaction and PA and a stronger negative relationship between leisure satisfaction and NA. These findings suggest that screening caregivers for level of burden may help identify those most likely to benefit from behavioral interventions. 相似文献

Stereotype activation is often described as beyond control, unable to be prevented by willing it or engaging the self-regulatory system. Four experiments illustrate that this initial stage of the stereotyping process is controllable. Stereotypes are shown to be implicitly inhibited as part of a goal shielding process. In each experiment, egalitarian goals are triggered through a task in which participants contemplate a past failure at being egalitarian to African American men. This is followed in each experiment by a task that measures stereotype activation/inhibition using reaction times to words (either control words or stereotype-relevant words) that follow the presentation of either faces of Black or White men. The first two experiments examine participants with egalitarian goals versus those with a control goal, whereas the last two experiments examine people with egalitarian goals versus those whose egalitarian strivings have been satisfied (by contemplating success at being egalitarian). Only participants with egalitarian goals exhibit stereotype inhibition, and this occurs despite the fact that they lack awareness of the inhibition and lack the conscious intent to inhibit stereotypes at the time the response is made. 相似文献

Different brain mechanisms between stereotype activation and application: evidence from an ERP study
Jia L Dickter CL Luo J Xiao X Yang Q Lei M Qiu J Zhang Q 《International journal of psychology》2012,47(1):58-66
Stereotyping involves two processes in which first, social stereotypes are activated (stereotype activation), and then, stereotypes are applied to given targets (stereotype application). Previous behavioral studies have suggested that these two processes are independent of each other and may have different mechanisms. As few psychophysiological studies have given an integrated account of these stages in stereotyping so far, this study utilized a trait categorization task in which event-related potentials (ERPs) were used to explore the brain mechanisms associated with the processes of stereotype activation and its application. The behavioral (reaction time) and electrophysiological data showed that stereotype activation and application were elicited respectively in an affective valence identification subtask and in a semantic content judgment subtask. The electrophysiological results indicated that the categorization processes involved in stereotype activation to quickly identify stereotypic and nonstereotypic information were quite different from those involved in the application. During the process of stereotype activation, a P2 and N2 effect was observed, indicating that stereotype activation might be facilitated by an early attentional bias. Also, a late positive potential (LPP) was elicited, suggesting that social expectancy violation might be involved. During the process of the stereotype application, electrophysiological data showed a P2 and P3 effect, indicating that stereotype application might be related to the rapid social knowledge identification in semantic representation and thus may be associated with an updating of existing stereotypic contents or a motivation to resolve the inconsistent information. This research strongly suggested that different mechanisms are involved in the stereotype activation and application processes. 相似文献

Recent studies have consistently demonstrated that conscious perception interacts with exogenous attentional orienting, but it can be dissociated from endogenous attentional orienting (Chica, Lasaponara, et al., 2011, Wyart and Tallon-Baudry, 2008). It has been hypothesized that enhanced conscious processing at exogenously attended locations results from a synergistic action of spatial orienting, bottom-up activation, and phasic alerting induced by the abrupt onset of the exogenous cue (Chica, Lasaponara, et al., 2011). Instead, as endogenous cues need more time to be interpreted, the phasic alerting they produce may have dissipated when the target appears. Furthermore, endogenous cues presumably elicit a weak bottom-up activation at the cued location. Consistent with these hypotheses, we observed that endogenous attention modulated conscious perception, but only when phasic alerting or bottom-up activation was increased. Results are discussed in the context of recent theoretical models of consciousness (Dehaene, Changeux, Naccache, Sackur, & Sergent, 2006). 相似文献

IntroductionDeath and injury from road traffic is a public health problem worldwide and accordingly there is substantial interest and investment in developing interventions to change road user behaviour. Alongside this, there is growing awareness of the need to evaluate interventions and to identify the most effective mechanisms by which behaviour can be changed. Progress has been hindered due to lack of a common taxonomy with which to define specific techniques used in attempts to change behaviour.ObjectiveBehavioural Change Techniques (BCTs) have been successfully deployed to change a range of different health behaviours. This paper defines a series of BCTs that can be applied in the road safety setting and asks which ones are found in road safety interventions for young road users?MethodAbraham and Michie (2008) identified twenty-six techniques used in behavioural change interventions. These BCTs, plus one other adapted from forensic psychology, are classified into nine groupings. Six educational road safety interventions commonly used in the UK with pre-drivers and young, novice drivers are characterised in terms of the BCTs they employ.ResultsOnly a small subset of BCTs are employed in most of the interventions. They concentrate primarily on increasing awareness of the risks associated with a particular behaviour, and the severity of the potential adverse consequences.ConclusionRecommendations are given for improving the effectiveness of road safety interventions for young people including young, novice drivers by increasing the range of BCTs deployed. 相似文献

Challenging stressors have been positively linked to various work outcomes. However, the role of individual differences in stress appraisal in shaping the function of challenging stressors and work outcomes has been rarely discussed. Drawing on the individual differences perspective, the authors propose that employees higher in challenge appraisal are more likely to have challenging stressors and are more responsive to such stressors to have a higher positive affect at work. Results obtained from 117 employees supported the hypotheses. The results indicated that challenge appraisal is positively related to challenging stressors. In addition, challenging stressors has a positive association with positive affect at work when challenge appraisal is high but has a null association when challenge appraisal is low. The findings suggest that challenging stressors does not necessarily bring positive work outcomes as suggested in past studies and highlight the importance of considering dispositional tendency in stress appraisal when looking into the function of challenging stressors and work outcomes. 相似文献
