决策中的延迟选择行为

延迟选择(choice deferral)指个体在应该作出选择的时候却决定不作选择,包括推迟选择(如选择延迟选项)或拒绝在可选项中选择一个选项。本文首先探讨了影响延迟选择行为的认知因素和情绪因素;随后讨论了当在决策情景中引入延迟选项时,延迟选项对决策者随后情绪体验和决策行为的影响;最后对未来研究进行了展望。     

When do peers influence adolescent males' risk taking? Examining decision making under conditions of risk and ambiguity

Risk taking is highly prevalent among adolescent males, and a range of studies have shown that decisions become riskier if a peer is present. However, previous studies have typically provided participants with explicit probabilities of risk in each situation. This does not accurately reflect adolescents' real‐world risk taking, where decisions are made in ambiguous situations alongside their peers. Aiming for a more ecologically valid design, the present experiment manipulated situational ambiguity and examined its interplay with group decision making and developmental factors. Adolescent males (N = 202) aged 12–15 completed a “Wheel of Fortune” task and then self‐reported their score, presenting an opportunity to cheat as a measure of antisocial risk taking. As predicted, adolescents were more likely to take risks when probabilities were ambiguous rather than explicit. Further, higher levels of gambling choices were made by groups in ambiguous, but not risk situations. Age significantly predicted gambling in ambiguous conditions, whereas developmental dispositions (risk perception, reward sensitivity, and inhibitory control) did not play a role. Findings provide an insight into the social and situational conditions under which adolescent males engage in reckless behavior.     

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.     

直觉还是推理,道德判断如何形成?

道德判断形成的机制一直存在争议,许多研究者通过实证研究来探索诸因素对道德判断的影响,这有助于理清不同因素的作用,但却难以构建道德判断形成的理论框架。文章系统性地回顾和总结了道德判断形成的五个经典理论模型及其相关理论,并结合实证研究的成果梳理了道德判断形成中理性、情绪、认知、直觉和推理之间的关系。基于此,构建了以直觉和推理为基本路径,基于规则的认知和情绪为调节因素的道德判断形成的理论框架。现有的理论模型和实证研究在该框架下均可以的得到较好的解释。同时,根据该框架,建议未来的实证研究中应当注重对影响因素的分类以及对实验情景的控制。     

Is There Social Consensus Regarding Researcher Conflicts of Interest?

Consensus around what constitutes researcher conflicts of interest (COIs) and awareness of their influence on our research are two critical steps in ensuring the integrity of our science. In this research, data were collected from individual scholars via 2 surveys 5 years apart and from journals and associations to examine the level of social consensus and moral awareness among scholars, journals, and associations regarding researcher COIs. Although we observed increases in level of social consensus and moral awareness between 2012 and 2017, results still revealed limited agreement about what relationships constitute a COI and limited awareness about the presence of and the ethical issues surrounding COIs. Although all journals and associations we examined supported COI disclosure, most did not provide researchers with detailed COI-related information, guidance, or disclosure tools. Limited social consensus and moral awareness regarding COIs is problematic because it inhibits the recognition, disclosure, and management of COIs and limits ethical decision making. We need to continue and enhance discussions about COIs and aim to create consensus and awareness where we do not have it with the goal of reducing potential scientific misconduct related to COIs.     

Disconfirming Expectations: Incorrect Imprecise (vs. Precise) Estimates Increase Source Trustworthiness and Consumer Loyalty

Estimations that include numerical information are ubiquitous in our daily lives, for example, housing prices, calories, etc. In the present work, we investigate how the type of information used in an estimate, particularly its level of imprecision, influences evaluations of source trustworthiness after the target value of the estimate is revealed. Specifically, building upon prior work suggesting that (a) imprecise estimates are perceived to be less accurate than precise estimates and (b) performing below expectations results in negative source evaluations, we hypothesize that if the estimate is revealed to be incorrect, imprecise estimates (i.e., 400) elicit higher source trustworthiness than precise estimates (i.e., 417), even if the imprecise estimate is objectively more incorrect (i.e., target value: 570). In addition, we find that this effect also influences consumers’ loyalty toward the source of the estimate. Four studies and a single‐paper meta‐analysis offer triangulating evidence for this prediction and its underlying psychological mechanism. Overall, this work contributes to research on estimates, source evaluations, numerical information, and the influence of errors on consumer behavior.     

Some Hedonic Consequences of Perspective‐Taking in Recommending

What do people enjoy about making recommendations? Although recommendation recipients can gain useful information, the value of these exchanges for the information provider is less clear in comparison. In this article we test whether a common recommendation heuristic—egocentric projection—also has hedonic consequences, by conducting experiments that compare recommendations (suggestions for another person) to reviews, in which people merely express their own preferences. Over five studies, people preferred reviewing over recommending. Recommenders enjoyed themselves less when they had to take their recipients' perspective, to the extent that the recipients' tastes were different from their own. These results suggest that self‐expression can be intrinsically rewarding for recommendation makers, and that recommendation seekers can elicit more information by asking for reviews instead.     

The value of job crafting for work engagement,task performance,and career satisfaction: longitudinal and quasi-experimental evidence

We examine how job crafting (i.e. seeking resources, seeking challenges, decreasing demands) increases the person-job fit of employees. In Study 1, we studied job crafting’s effects over time. 111 employees filled out a questionnaire at two time points with 6 months in between. We found that seeking resources behavior at Time 1 positively affected work engagement, task performance, and career satisfaction at Time 2. Decreasing demands at Time 1 negatively affected work engagement, task performance, and career satisfaction at Time 2. In Study 2, we tested a job crafting intervention using a quasi-experimental design (i.e., intervention group, N = 60, and a control group, N = 59). The intervention was successful, as participants in the intervention group increased seeking resources and decreasing demands behaviors. Furthermore, seeking resources behavior was the main driver of increased participants’ work engagement, task performance, and career satisfaction.     

Withholding and Withdrawing Life-Sustaining Treatment: Ethically Equivalent?

Withholding and withdrawing treatment are widely regarded as ethically equivalent in medical guidelines and ethics literature. Health care personnel, however, widely perceive moral differences between withholding and withdrawing. The proponents of equivalence argue that any perceived difference can be explained in terms of cognitive biases and flawed reasoning. Thus, policymakers should clear away any resistance to accept the equivalence stance by moral education. To embark on such a campaign of changing attitudes, we need to be convinced that the ethical analysis is correct. Is it? In this article, I take a closer look at the moral relation between withholding and withdrawing. My conclusion is that withholding and withdrawing are not in general ethically equivalent. Thus, medical guidelines should be rewritten, and rather than being “educated” away from their sound judgments, medical professionals and patients should have nuanced medico-ethical discussions regarding withholding and withdrawing treatment.     

A reinforcement learning approach to personalized learning recommendation systems

Personalized learning refers to instruction in which the pace of learning and the instructional approach are optimized for the needs of each learner. With the latest advances in information technology and data science, personalized learning is becoming possible for anyone with a personal computer, supported by a data-driven recommendation system that automatically schedules the learning sequence. The engine of such a recommendation system is a recommendation strategy that, based on data from other learners and the performance of the current learner, recommends suitable learning materials to optimize certain learning outcomes. A powerful engine achieves a balance between making the best possible recommendations based on the current knowledge and exploring new learning trajectories that may potentially pay off. Building such an engine is a challenging task. We formulate this problem within the Markov decision framework and propose a reinforcement learning approach to solving the problem.
