关联负变化(CNV)与反应时的关系

本实验采用选择性叠加方法,研究了关联负变化(Contingent NegativVariation以下简称CNV)与反应时的关系。证明:最长、最短反应时差异显著时,相对应的CNV面积差异也显著。CNV的这种差异主要表现在CNV面积的后半部分。对形成这种现象的原因作了讨论。

Fragile promise: The role of justification in promise-breaking

People who consider themselves moral sometimes use self-serving justifications to rationalize their selfish behaviours. Previous studies have tested the role of ambiguity in justifying wrongdoings, but it remains unclear whether ambiguity also plays a role in justifying promise-breaking behaviour and whether heterogeneity exists. To investigate justification in promise-breaking, we introduced a new experimental paradigm called the card-guessing task and used hierarchical cluster analysis to classify participants based on their promise-breaking decisions in unambiguous and ambiguous conditions. Experiment 1 revealed three clusters of solutions: Cluster 1 always kept their promises (i.e., keepers); Cluster 2 only exploited the vague promises and broke their promises in the ambiguous condition (i.e., intermediates); Cluster 3 tended to take advantage of vague promises and broke their promises irrespective of ambiguity (i.e., breakers). Experiment 2 confirmed that participants in the three clusters differed in their norm-abiding preferences and social value orientations. Keepers were more altruistic and had a stronger sense of norm compliance than intermediates and breakers. In conclusion, our study demonstrates that self-serving justifications were more likely to be employed by people who are moderately sensitive to deviation from social norms, which has implications for strategic interventions and policy formulation concerning unethical behaviour.

Prosocial orientation and COVID-19 vaccine willingness in the U.S.

Despite evidence of the safety and effectiveness of COVID-19 vaccines and their wide availability, many in the U.S. are not vaccinated. Research demonstrates that prosocial orientations predict COVID-19 health behaviors (e.g., social distancing) and vaccination intentions, however, little work has examined COVID-19 vaccination willingness in the U.S. since vaccines were approved. Findings from two U.S. samples show that, in contrast to other COVID-19 health behaviors, vaccine willingness in unvaccinated people is unrelated to prosocial orientation. Study 2 demonstrates that the lack of association between vaccine willingness and prosocial orientation in unvaccinated participants was specific to those with stronger beliefs that COVID-19 vaccines are ineffective. Thus, in prosocial people, perceptions of vaccines' ineffectiveness may undermine COVID-19 vaccine willingness.     

The myth of regaining control: Ostracism increases superstitious tendencies

Whether and how interpersonal experiences predispose people to show superstitious tendencies have been largely unexamined by past studies. By adopting a multimethod approach, three studies tested (a) whether ostracism increases superstitious tendencies through thwarted perceived control, (b) whether the dispositional need for closure moderates the effect of ostracism on superstitious tendencies and (c) whether restoring ostracized people's thwarted control weakens their superstitious tendencies. The results revealed that ostracized participants had higher superstitious tendencies than nonostracized participants did (Studies 1–3). Moreover, thwarted control mediated the effect of ostracism on superstitious tendencies (Study 2). In addition, the dispositional need for closure moderated the effect of ostracism on superstitious tendencies, such that the effect was stronger among participants with a high need for closure (Studies 1–2). Finally, restoring ostracized participants' perceived control weakened the effect of ostracism on superstitious tendencies (Study 3). Altogether, these findings feature the essential role of thwarted perceived control in understanding the link between ostracism and superstitious tendencies and the implication of control restoration in weakening the link. They also highlight the importance of dispositional characteristics in moderating people's responses to superstitions following ostracism and related forms of interpersonal maltreatment.     

不同智商儿童和唐氏综合症儿童的关联性负变(CNV)

比较不同智商正常儿童和唐氏综合症(Down’s Syndrome)儿童的关联性负变(Contingent Negative Variation CNV)。结果是:智力缺陷儿童的CNV幅度明显下降甚至缺失。智力较高儿童CNV较大,CNV的晚成分与智商,尤其是言语智商密切相关,智商和言语智商越高,晚成分幅度越大。似乎晚成分更能反映人的语言方面的能力。早成分则与语言、操作以及全量表智商都无明显关系。     

The effect of gap depth on the perception of whether a gap is crossable

Four experiments were performed in order to examine the effect of gap depth on human observers’ perception of whether or not a gap is crossable. Experiments 1 and 2 showed that as the gap’s depth increased, observers tended to increasingly underestimate the maximum width of a gap they could step across. Experiments 3 and 4 clarified this finding: The observed covariation of perceived gap crossability and gap depth depended on the observer’s direction of gaze, rather than on the physical depth of the gap. The optical relations to which observers might be attending are discussed, as well as the possibility that cognitive-affective processes might have contributed to observers’ underestimation of their actual capabilities.     

Teacher stress and guidance work in Hong Kong secondary school teachers

Major sources of stress in Hong Kong teachers were investigated, with specific reference to guidance work as a potential source of stress. A survey of 415 secondary school teachers revealed that guidance-related aspects of work constituted a major dimension of stress, with guidance teachers, female teachers, younger teachers and junior teachers perceiving more stress than their counterparts in this dimension. Workload and time pressure were perceived as the most stressful aspects of work for all teachers. Results also showed an association between stress and job satisfaction, and biographical variables. Implications of the findings for teachers doing guidance work in Hong Kong and internationally are discussed.
