和谐动机与整合性谈判结果*

人们追求人际和谐的动机具有双重性,一方面是为了促进和谐,另一方面是为了避免破裂,两种动机驱使人们在面对冲突时采取不一样的应对策略。那么,谈判作为一种与冲突密不可分的情境,谈判者的和谐的动机将会对他们的谈判结果产生什么影响呢？本研究整合和谐动机和谈判两方面的文献,探讨了在整合性谈判中两种不同的和谐动机与谈判者的行为以及谈判结果之间的关系。研究结果表明,1)在个体层面上,谈判者的促进和谐动机与其个体收益以及对谈判双方关系的评价正相关,而避免破裂动机与其个体收益以及对谈判双方关系的评价负相关；2)在谈判对子层面上,谈判双方总体的促进和谐与谈判双方的联合收益正相关。本研究不仅进一步论证了和谐动机的概念效度,而且从理论上论证了和谐动机与谈判的关系,对于谈判者具有实践意义。     

Transfer of conditioned fear and avoidance: Concurrent measurement of arousal and operant responding

A reversal design was employed for the analysis of transfer of fear and avoidance through equivalence classes. Two 5-member equivalence classes (A1-B1-C1-D1-E1 and A2-B2-C2-D2-E2) were established. Then B1 and C1 were paired with shock (CS+) and served as S^Ds in avoidance training (B2 and C2 were trained as CS-/S^∆s for avoidance). Further avoidance training followed with D1 and E1 (as S^Ds) and D2 and E2 (as S^∆s), with the first presentation of each of these stimuli serving as the first transfer test. Afterwards, aversive conditioning contingencies were reversed: B2 and D2 were paired with shock and trained as S^Ds for avoidance, B1 and D1 were presented without shock (CS-/S^∆s). Transfer was tested again with C1, E1, C2 and E2. This reversal was implemented to allow for the within-subject replication of transfer effects upon changes in the function of only a subset of each class's elements. Avoidance (key presses) and conditioned fear (skin conductance and heart rate) were simultaneously measured. Results show a clear transfer effect for avoidance, with between- and within-subject replications. For physiological measures, transfer effects in the first test could only be imputed on the basis of group-based inferential statistical analysis. Evidence for between-subject replication was weaker, with only a limited proportion of participants meeting the individual criterion for transfer.     

Volunteering in older adulthood is associated with activity engagement and cognitive functioning

ABSTRACT

Introduction: Given evidence that activity engagement in older adulthood can have protective effects on the aging brain, we investigated the idea that volunteering in the community, which often encompasses social, cognitive, and physical activity, might benefit cognition.

Method: Ninety-one retired 65- to 75-year-olds reported their sociodemographic characteristics, wellbeing, volunteering, and activity engagement. They also completed computerized cognitive tests that tapped specific functions known to decline disproportionately with age.

Results: Volunteering at least monthly was associated with better working memory and more social and cognitive activity. Mediation analyses indicated that volunteering was indirectly related to switching performance via cognitive activity. However, the volunteering-working memory association did not depend on activity engagement, leaving the underpinning mechanisms unclear.

Conclusions: These findings provide new insight into positive associations between older people’s volunteering, activity engagement, and cognitive functioning. However, further work is needed to understand the mechanisms that drive volunteering-cognition links, and to establish causality.     

How pills undermine skills: Moralization of cognitive enhancement and causal selection

Despite the promise to boost human potential and wellbeing, enhancement drugs face recurring ethical scrutiny. The present studies examined attitudes toward cognitive enhancement in order to learn more about these ethical concerns, who has them, and the circumstances in which they arise. Fairness-based concerns underlay opposition to competitive use—even though enhancement drugs were described as legal, accessible and affordable. Moral values also influenced how subsequent rewards were causally explained: Opposition to competitive use reduced the causal contribution of the enhanced winner’s skill, particularly among fairness-minded individuals. In a follow-up study, we asked: Would the normalization of enhancement practices alleviate concerns about their unfairness? Indeed, proliferation of competitive cognitive enhancement eradicated fairness-based concerns, and boosted the perceived causal role of the winner’s skill. In contrast, purity-based concerns emerged in both recreational and competitive contexts, and were not assuaged by normalization.     

Advancing training and transfer research through the application of nonlinear dynamics

ABSTRACT

The study of training transfer as something that occurs over time with its own underlying process has been very limited in the training literature to date. This paper argues that we can better understand how transfer unfolds over time, and why it unfolds in any particular way, by considering important theoretical and mathematical concepts from nonlinear dynamics. We draw on nonlinear concepts, such as attractors, to describe how and when training interventions are likely to succeed and how subsequent transfer may unfold in relation to those concepts. We then explicate how taking a dynamic view of transfer forces us to change how our field currently studies transfer methodologically, and then give an extended example of how such an advancement may provide for richer theories regarding the process of transfer by focusing on the effects of supervisor support over time. We close with some practical recommendations informed by our view.
