绿色助推（英文）

我们人类当前的生活方式不是可持续的。提升可持续性的途径之一是发展更绿色的科学技术,另一种补充性途径是改变人们的态度、习惯和行为。在本文中,我们讨论了6种心理技术,其宗旨是推动或助推(nudge)人们做出更环保的选择和行为。这些心理技术涵盖范围非常广泛,有些可以远程使用,如在通知公告中建构沟通信息,有些则涉及对人们的决策情境做出的改变。因此,本综述关乎到各行业从业人员,如市场营销人员、政策制定者、消费者代表等。对于每项心理技术,我们讨论了其认知和(或)情绪的理论性基础。此外,我们探讨了目前文献中存在的空白,并提出了可填补这些空白的未来研究方向。     

Age-Associated Differences in Positional Variability Are Greater With the Lower Limb

The authors’ purpose was to determine the interaction of age and limb used on positional variability at different loads. Eleven young adults and 10 older adults were asked to accurately match and maintain a horizontal target line with 5° abduction of their index finger and 5° dorsiflexion of their ankle for 20 s at loads ranging from 2 to 50% of the maximal load that could be lifted with each limb. The visual gain was kept constant at 1° (visual angle). Positional variability was greater in older adults for both limbs, nonetheless age-associated differences were greater for the ankle dorsiflexion task compared with the abduction of the index finger task. In addition, we found that, independent of age, motor output variability was greater with the lower limb. These results provide novel evidence that older adults may exhibit greater impairments in motor control with the foot compared with the finger. Furthermore, these findings support the idea, using a different task than previous literature, that the lower limb has greater motor output variability than the upper limb.     

Age differences in moral judgment: Older adults are more deontological than younger adults

In 2 studies, an older and a younger age group morally evaluated dilemmas contrasting a deontological judgment (do not harm others) against a utilitarian judgment (do what is best for the majority). Previous research suggests that deontological moral judgments are often underpinned by affective reactions and utilitarian moral judgments by deliberative thinking. Separately, research on the psychology of aging has shown that affect plays a more prominent role in the judgments and decision making of older (vs. younger) adults. Yet age remains a largely overlooked factor in moral judgment research. Here, we therefore investigated whether older adults would make more deontological judgments on the basis of experiencing different affective reactions to moral dilemmas as compared with younger adults. Results from 2 experiments indicated that older adults made significantly more deontological moral judgments. Mediation analyses revealed that the relationship between age and making more deontological moral judgments is partly explained by older adults exhibiting significantly more negative affective reactions and having more morally idealistic beliefs as compared with younger adults.     

The relationship between bullying, victimization, trait emotional intelligence, self-efficacy and empathy among preadolescents

The purpose of the present study was to examine the relationship between bullying, victimization and a number of social-emotional variables such as trait emotional intelligence, empathy and self-efficacy in 206 elementary school 6th graders in Greece. Results indicated that boys reported significantly more direct and indirect bullying behaviors than girls, and higher victimization. Bullying was negatively correlated with overall self-efficacy and its academic component, trait emotional intelligence, empathy and its cognitive component, while victimization was negatively correlated with overall self-efficacy and its three dimensions, trait emotional intelligence, affective and cognitive empathy. Gender, trait emotional intelligence, and cognitive empathy significantly predicted bullying, whereas victimization was predicted by gender, trait emotional intelligence and affective empathy.     

Time but not force is transferred between ipsilateral upper and lower limbs

The authors compared the force and time endpoint accuracy of goal-directed ipsilateral upper and lower limb isometric contractions and determined the components of motor performance that can be transferred from 1 limb to the other after practice. Ten young adults (27.4 +/- 4.4 years) performed 100 trials that involved their matching peak force to a force-time target with ankle dorsiflexor and elbow flexor muscles. The peak force error and variability was greater for ankle dorsiflexor contractions than for elbow flexor contractions, whereas the timing error and variability did not significantly vary with limb. There was transfer of timing, but not force, of motor output between upper and lower limbs. The timing error of the elbow flexor contractions decreased by 23% when those contractions were preceded by ankle dorsiflexor contractions, and the timing error of the ankle dorsiflexors decreased by 24% when those contractions were preceded by elbow flexor contractions. These finding therefore suggest that timing of an aiming isometric contraction may be organized at a common part of the brain for the upper and lower limbs.     

Predicting bullying and victimization among early adolescents: Associations with disruptive behavior disorders

Bullying is a common problem faced by children and adolescents in schools. One hypothesis that needs to be examined regarding the causation of this problem is whether being a bully or a victim may stem from disparate underlying patterns of psychopathology. Results are particularly scarce regarding the association between bully‐victim problems and disruptive behavior disorders. The present study sought to investigate the association between DSM‐IV symptoms of Oppositional Defiant Disorder (ODD), Conduct Disorder (CD), and bully‐victim problems in a sample of 202 adolescents, aged 12–15, attending two junior high schools in Cyprus, to determine whether these symptoms differentiate between bullies and victims and provide a new approach to the understanding of bully‐victim problems. Students completed measures of bullying, victimization, disruptive behavior disorder symptoms, and self‐esteem, along with demographic questions. On the basis of their responses, teenagers were classified as bullies, victims, or both bullies and victims. Those who were bully/victims reported greater CD symptomatology. CD and low self‐esteem were predictive of bullying, whereas ODD and low self‐esteem were predictive of victimization. Aggr. Behav. 30:520–533, 2004. © 2004 Wiley‐Liss, Inc.

Many moral buttons or just one? Evidence from emotional facial expressions

We investigated whether moral violations involving harm selectively elicit anger, whereas purity violations selectively elicit disgust, as predicted by the Moral Foundations Theory (MFT). We analysed participants’ spontaneous facial expressions as they listened to scenarios depicting moral violations of harm and purity. As predicted by MFT, anger reactions were elicited more frequently by harmful than by impure actions. However, violations of purity elicited more smiling reactions and expressions of anger than of disgust. This effect was found both in a classic set of scenarios and in a new set in which the different kinds of violations were matched on weirdness. Overall, these findings are at odds with predictions derived from MFT and provide support for “monist” accounts that posit harm at the basis of all moral violations. However, we found that smiles were differentially linked to purity violations, which leaves open the possibility of distinct moral modules.
