Living Under the Threat of Relocation: Spouses' Perceptions of the Threat and Coping Resources

This study examined the contribution of couples, shared perceptions of the threat of relocation, and the buffering effect of personal and marital resources in coping with stress. The study was conducted with a random sample of 95 couples in the Golan Heights region in Israel, where a unique situation exists in which families live under a threat of relocation, due to the peace negotiations between Israel and Syria. Two resources were examined: potency and marital quality Results showed that potency made the greatest contribution to coping either with demands or stress, both in couples who had similar or different future scenarios, while marital quality was found to relieve the stress only in couples who shared the same future scenarios. The average level of stress was found to be higher but not significant among couples with different future scenarios.     

Burying by rats in response to aversive and nonaversive stimuli

Previous investigations have shown that rats bury a variety of conditioned and unconditioned aversive stimuli. Such burying has been considered as a species-typical defensive reaction. In the present studies, rats buried spouts filled with Tabasco sauce, or condensed milk to which a taste aversion was conditioned, but did not bury water-filled spouts or spouts filled with a palatable novel food (apple juice) to which a taste aversion was not conditioned. However, in other experiments rats consistently and repeatedly buried Purina Rat Chow, Purina Rat Chow coated with quinine, and glass marbles. This indicates that a variety of stimuli, not all aversive or novel, evoke burying by rats. Whereas the behavior may reasonably be considered as a species-typical defensive behavior in some situations, the wide range of conditions that occasion burying suggests that the behavior has no single biological function.     

Inconsistency and uncertainty in multi-attribute judgment of human performance

This paper examines the effect of uncertainty and inconsistency on the judgment of human performance. The results indicate that the effect of inconsistency on judgment is not mediated by subjective uncertainty. We find that both the level and the extremity of judgment decrease with uncertainty. These effects are explained, respectively, by uncertainty aversion and by regressiveness. We also find that both the level and the extremity of judgment of human performance increase with inconsistency. These effects are explained by reliance on integration rules in which judgment is based primarily on some aspects of the information, while other aspects are, to some extent, ignored.     

企业新产品开发决策的不确定性和决策策略模拟实验研究

本文以企业新产品开发为决策内容,根据决策策略的规定性理论框架和先前调查所得决策案例,设计四种决策情景来代表四种不确定状态,通过５６名来自５个工厂的管理人员的现场模拟实验,着重研究这类决策的不确定性和决策策略之间关系。结果发现,在新产品开发的决策中,决策策略随不确定状态而改变;决策情景的不确定程度和决策策略没有严格的—一对应关系;在四类不确定决策情景下,都有管理人员采用混合型策略。这一发现同混合扫瞄策略观点和垃圾罐模型的思想相一致。并且,随着决策情景的不确定程度加大,决策时间逐渐延长。最后我们提出了应继续研究的课题。     

Observing behavior in a computer game.

Contingencies studied in lever-pressing procedures were incorporated into a popular computer game, "Star Trek," played by college students. One putative reinforcer, the opportunity to destroy Klingon invaders, was scheduled independently of responding according to a variable-time schedule that alternated unpredictably with equal periods of Klingon unavailability (mixed variable time, extinction schedule of reinforcement). Two commands ("observing responses") each produced stimuli that were either correlated or uncorrelated with the two components. In several variations of the basic game, an S-, or bad news, was not as reinforcing as an S+, or good news. In addition, in other conditions for the same subjects observing responses were not maintained better by bad news than by an uninformative stimulus. In both choices, more observing tended to be maintained by an S- for response-independent Klingons when its information could be (and was) used to advantage with respect to other types of reinforcement in the situation (Parts 1 and 2) than when the information could not be so used (Part 3). The findings favor the conditioned reinforcement hypothesis of observing behavior over the uncertainty-reduction hypothesis. This extends research to a more natural setting and to multialternative concurrent schedules of events of seemingly intrinsic value.     

Navigating uncertainty in human social decision-making: Consequences and coping strategies

Uncertainty is a fundamental aspect of human social life. Based on fruitful findings, the current review aims to establish a schema that outlines the relationship between uncertainty and human social decision-making: the influences of uncertainty on social decision-making (mainly prosocial behaviors) and the strategies commonly employed to reduce social uncertainty. Human prosocial behaviors are modulated by both social and nonsocial uncertainty. Specifically, uncertainty decreases prosocial behaviors by providing moral wiggling room or promoting loss aversion but also helps maintain relationships by mitigating negative interactions. Moreover, impression formation, impression updating, and compliance with social norms are crucial strategies for coping with social uncertainty, but they are subject to various biases. Finally, we highlight some important issues that need to be addressed in future studies. In summary, the current review deepens our understanding of the role of uncertainty in social behaviors.     

“Some days are much holier than others”: Relational uncertainty and partner influence in Christian dating couples' sexual intimacy negotiation

When intrafaith couples' religion strictly prohibits premarital sexual intercourse, negotiating sexual intimacy can become a multilayered process of identity negotiation that compounds the difficulty of sexual communication. Through the lens of relational turbulence theory, this study explored how devout Christian couples negotiate sexual intimacy by reanalyzing qualitative interview data the first author collected in 2017 from 16 self-identified Christians (8 heterosexual couples). Seven themes revealed how relational uncertainty, partner interference, and partner facilitation manifested in the context of sexual intimacy negotiation. Themes of relational uncertainty experience and prevention included assumption of shared values, relationship talk, and sexual behaviors as an uncertainty catalyst. Partner facilitation and interference emerged as themes of sexual escalation and de-escalation including snowball effect, pinpointing underlying motivations for boundary violations, gatekeeping sexual temptation, and drawing from shared values of sacrifice and prayer. These interpretive findings advance the literature on relational turbulence theory and provide Christian dating couples with practical advice for how to negotiate sexual intimacy in committed premarital relationships.     

Mementos and the endowment effect

This research provides evidence for a new moderator of the endowment effect: having a memento of the endowed object. Three studies adapting classic endowment effect paradigms and using a variety of endowment objects and mementos demonstrate that having a memento of an endowment increases willingness to trade the endowment and decreases selling prices for the endowment. We provide evidence that mementos attenuate the endowment effect regardless of whether the memento is a separate small gain when facing the loss of the endowment or a small part of the original endowment that is kept. Examining mementos in context of the endowment effect not only provides insight into the psychology underlying the reluctance to part with one's endowment but also other consumer disposition behaviors.     

基于预期理论的风险决策的神经机制

预期理论基于对期望效用理论的批判与发展,提出了价值函数与权重函数,对以往风险决策研究中所发现的现象进行了很好的预测与解释。预期理论的核心概念包括参照依赖、损失规避与权重函数。基于预期理论的一些决策偏差包括框架效应、禀赋效应和默认偏差也部分揭示了与人们风险决策有关的脑区。近年来,通过采用功能性核磁共振等脑成像手段对预期理论的一些核心成分进行的研究表明,涉及到人们风险决策的脑区主要有前额叶、纹状体、脑岛与杏仁核。未来的研究可以从预期理论的产生根源、个体发展以及遗传基因等角度进行进一步的探讨。
