Decisions Under Distress: Stress Profiles Influence Anchoring and Adjustment

ABSTRACT— People frequently make decisions under stress. Understanding how stress affects decision making is complicated by the fact that not all stress responses are created equal. Challenge states, for example, occur when individuals appraise a stressful situation as demanding, but believe they have the personal resources to cope, and are characterized by efficient cardiovascular reactivity and approach motivation. Threat states, in contrast, occur when situational demands are perceived to outweigh resources and are characterized by less efficient cardiovascular reactivity and withdrawal motivation. We randomly assigned participants to social-feedback conditions (i.e., positive or negative feedback) designed to engender challenge or threat, or a no-stress condition. Participants then completed an anchoring-and-adjustment questionnaire. Those assigned to the challenge condition adjusted more from self-generated anchors than those assigned to the threat condition. Cardiovascular responses mediated the relationship between condition and adjustment. This study demonstrates the importance of considering profiles of cardiovascular reactivity when examining the influence of stress on decision making.     

The Effects of Decision Outcome Dispersion Upon Organizational Decision Making

The effects of varying decision outcome dispersion on organizational decision making were investigated under individual and group decision making conditions. Thirty-six female and pg]36 male subjects made decisions for organizational decision scenarios in which outcomes affected primarily the decision maker, people other than the decision maker, or a group of which the decision maker was a member. Subjects rated their levels of perceived risk and confidence in their decisions and made decisions within a simulated context of either a small or a large organization. Results indicated that subjects perceived significantly less risk and more confidence in their decisions when outcomes affected primarily themselves rather than others regardless of whether the decisions were made individually or by a group. Males perceived their decisions as significantly more risky than females. Induced organizational size did not significantly influence decision making.

     

Mother still knows best: Maternal influence uniquely modulates adolescent reward sensitivity during risk taking

Adolescent decision‐making is highly sensitive to input from the social environment. In particular, adult and maternal presence influence adolescents to make safer decisions when encountered with risky scenarios. However, it is currently unknown whether maternal presence confers a greater advantage than mere adult presence in buffering adolescent risk taking. In the current study, 23 adolescents completed a risk‐taking task during an fMRI scan in the presence of their mother and an unknown adult. Results reveal that maternal presence elicits greater activation in reward‐related neural circuits when making safe decisions but decreased activation following risky choices. Moreover, adolescents evidenced a more immature neural phenotype when making risky choices in the presence of an adult compared to mother, as evidenced by positive functional coupling between the ventral striatum and medial prefrontal cortex. Our results underscore the importance of maternal stimuli in bolstering adolescent decision‐making in risky scenarios.     

For the Win: Risk‐Sensitive Decision‐Making in Teams

Risk‐sensitivity theory predicts that decision‐makers should prefer high‐risk options in high need situations when low‐risk options will not meet these needs. Recent attempts to adopt risk‐sensitivity as a framework for understanding human decision‐making have been promising. However, this research has focused on individual‐level decision‐making, has not examined behavior in naturalistic settings, and has not examined the influence of multiple levels of need on decision‐making under risk. We examined group‐level risk‐sensitive decision‐making in two American football leagues: the National Football League (NFL) and the National College Athletic Association (NCAA) Division I. Play decisions from the 2012 NFL (Study 1; N = 33 944), 2013 NFL (Study 2; N = 34 087), and 2012 NCAA (Study 3; N = 15 250) regular seasons were analyzed. Results demonstrate that teams made risk‐sensitive decisions based on two distinct needs: attaining first downs (a key proximate goal in football) and acquiring points above parity. Evidence for risk‐sensitive decisions was particularly strong when motivational needs were most salient. These findings are the first empirical demonstration of team risk‐sensitivity in a naturalistic organizational setting. Copyright © 2016 John Wiley & Sons, Ltd.     

Does the feedback from previous trials influence current decisions? A study on the role of feedback processing in making decisions under explicit risk conditions

Decision situations frequently provide information about the amount of gains and losses and winning probabilities. In decisions under these conditions, also called risk conditions, both the use of feedback and executive functions have been shown to influence the decision‐making process, as revealed in different patient populations. However, the influence of offering feedback in tasks examining decisions under risk conditions has not been investigated experimentally, so far. This was the aim of the present study. For this purpose, a sample of healthy individuals was examined with the Game of Dice Task, a decision‐making task that explicitly provides the rules for gains and losses and in which participants receive feedback after each trial. In addition, a modified version of this task was performed, in which the feedback after each trial and all associated feedback components were removed. Results indicate that participants had a lower performance in the modified Dice Task without feedback. They selected the disadvantageous alternatives more frequently, when they did not receive feedback following their choices. Task performance in either version was correlated with executive functioning. Conclusion: In decisions under risk conditions, both executive functions as well as the use of feedback following previous trials are important components for optimal performance. Results have implications for the interpretation of deficient decision making in patients with neuropsychological impairments as both disturbances in categorization and other cognitive processes as well as emotional dysfunctions can compromise decision making in risky situations.     

Performing a secondary executive task with affective stimuli interferes with decision making under risk conditions

Previous studies demonstrated that executive functions are crucial for advantageous decision making under risk and that therefore decision making is disrupted when working memory capacity is demanded while working on a decision task. While some studies also showed that emotions can affect decision making under risk, it is unclear how affective processing and executive functions predict decision-making performance in interaction. The current experimental study used a between-subjects design to examine whether affective pictures (positive and negative pictures compared to neutral pictures), included in a parallel executive task (working memory 2-back task), have an impact on decision making under risk as assessed by the Game of Dice Task (GDT). Moreover, the performance GDT plus 2-back task was compared to the performance in the GDT without any additional task (GDT solely). The results show that the performance in the GDT differed between groups (positive, negative, neutral, and GDT solely). The groups with affective pictures, especially those with positive pictures in the 2-back task, showed more disadvantageous decisions in the GDT than the groups with neutral pictures and the group performing the GDT without any additional task. However, executive functions moderated the effect of the affective pictures. Regardless of affective influence, subjects with good executive functions performed advantageously in the GDT. These findings support the assumption that executive functions and emotional processing interact in predicting decision making under risk.

Consumer Trust and Advice Acceptance: The Moderating Roles of Benevolence,Expertise, and Negative Emotions

I explored advice acceptance for high‐stakes decisions (i.e., those with subjectively important and risky outcomes), focusing on the relative influence of two components of consumer trust—benevolence and expertise—as well as perceived emotional decision difficulty. Participants solicited advice from experts when their decisions were low in perceived emotional difficulty but favored the advice of predominantly benevolent providers when making highly emotionally difficult decisions. Although consumers who faced emotionally difficult decisions were willing to trade off expertise for benevolence, they did not perceive this non‐normative trade‐off to influence decision quality. Instead, the results support a “stress buffering” effect whereby consumers were more confident in the accuracy of predominantly benevolent providers’ advice.     

Peer influence on risk taking, risk preference, and risky decision making in adolescence and adulthood: an experimental study

In this study, 306 individuals in 3 age groups--adolescents (13-16), youths (18-22), and adults (24 and older)--completed 2 questionnaire measures assessing risk preference and risky decision making, and 1 behavioral task measuring risk taking. Participants in each age group were randomly assigned to complete the measures either alone or with 2 same-aged peers. Analyses indicated that (a) risk taking and risky decision making decreased with age; (b) participants took more risks, focused more on the benefits than the costs of risky behavior, and made riskier decisions when in peer groups than alone; and (c) peer effects on risk taking and risky decision making were stronger among adolescents and youths than adults. These findings support the idea that adolescents are more inclined toward risky behavior and risky decision making than are adults and that peer influence plays an important role in explaining risky behavior during adolescence.     

Risk Taking in Decision Making for Others Versus the Self1

In two studies, we examined people's level of risk taking when making monetary decisions for other people rather than for themselves. Experiment 1 examined the role of regret in these situations; results show that regret concerns led to increased risk avoidance both when participants made decisions for other people as well as when making decisions for themselves. Experiment 2 tested whether skill tasks would lead to greater risk avoidance when the decision was for another person versus for oneself. This hypothesis was not supported, although men were more risk seeking than were women in both situations. Taken together, these studies suggest that many of the findings from risk research on individual decision making regarding financial situations generalize to decision making for others.     

认知闭合需要、框架效应与决策偏好

在带有模糊性的决策情境中,决策者个人的认知特征会对其判断决策产生重要影响。通过实验的方法,考察了认知闭合需要和特征框架效应对个体决策偏好的影响。93名工商管理硕士（MBA）参与了实验,研究的结果支持了本研究的3个假设,即认知闭合需要与特征框架效应不仅对被试的决策偏好存在显著的影响,而且二者还存在显著的交互作用。具体来说,研究发现,在模糊情境中：高认知闭合需要的被试偏好于立刻做出决策,而低认知闭合需要的被试偏好于暂缓做出决策;接收到正向框架信息的被试偏好于立刻做出决策,而接收到负向框架信息的被试偏好于暂缓做出决策;认知闭合需要与特征框架对被试的决策偏好还存在显著的交互作用。研究结论为根据个体认知闭合需要的水平来选拔决策者、利用框架效应来影响个体的信息加工方式进而提高决策质量提供了理论依据

越老越风险规避吗？——年龄对冲动性预测决策行为的调节效应

年老化伴随着风险承担倾向的改变,而决策行为受冲动性的影响是否受到年龄的调节尚不清楚。研究采用两种不同类型的决策任务以及Barratt冲动性量表,考察老年人风险承担在自我报告和决策行为上的改变。结果显示老年人在剑桥博弈任务中更加风险寻求而在模拟充气球任务中更加风险规避。同时冲动性可以显著预测模拟充气球的行为,且该预测受到年龄的调节。研究结果提示,老年人并不是单一的更加风险规避或者风险寻求,而是与任务特异性相关。同时,冲动性可以较好的预测年轻人的决策行为,而对老年人的决策行为没有预测作用。     

心理距离与决策者角色对风险决策的影响

采用改编的I0S量表测量自我与他人的心理距离,在收益和损失情境下,综合探讨了为他人和预测他人决策时心理距离对个体风险偏好的影响.结果发现:(1)与他人心理距离越远,个体决策时越偏好风险,且反应时越短;(2)个体预测他人决策时比为他人决策时更偏好风险,但两者反应时没有显著差异;(3)心理距离与决策者角色存在交互作用,即预测时个体认为远心理距离他人比近心理距离他人更冒险,而为他人决策时两者差异消失;(4)决策角色与决策框架、心理距离与决策框架存在交互作用:在收益框架下,自我他人心理距离较远时个体更偏好风险,且个体预测比为他人决策时更冒险,损失条件下无差异.依据相关理论对这些结果进行了分析讨论.     

Parent–Child Roles in Decision Making About Medical Research

Our objective is to understand how parents and children perceive their roles in decision making about research participation. Forty-five children (ages 4–15 years) with or without a chronic condition and 21 parents were the participants. A semistructured interview assessed perceptions of up to 4 hypothetical research scenarios with varying levels of risk, benefit, and complexity. Children were also administered the Peabody Picture Vocabulary Test, Third Edition, to assess verbal ability, as a proxy for the child's cognitive development. The audiotaped interviews were transcribed and analyzed for themes related to parent and child decision-making roles. Both parents and children varied in their perceptions of decision-making roles. Child perceptions of parental influence on decision making as knowledge-based increased with cognitive development, whereas perceptions of parental influence as power-based decreased. Both children and parents commented that they would collaborate with each other when making decisions. Collaborative decision making appeared to increase with cognitive development. These findings suggest that approaches to child assent and parent permission should consider the parent–child relationship and how children and families typically make decisions. Future research is necessary to explain variation in the process of research decision making across children and families, explore the role of collaboration on children's decision-making skills, and understand developmental trajectories and mechanisms related to research decision making.     

Individualism-Collectivism as a Boundary Condition for Effectiveness of Minority Influence in Decision Making

Results of this experiment demonstrate that individualists and collectivists react differently to minority influence. Based on the distinction between objectivity and preference norms in the minority influence literature, we hypothesize that individualism and collectivism influence (A) responses to minority influence (focusing on the target of influence) and (B) effectiveness of minority influence (focusing on the influence agent). Our results replicate past research and demonstrate improved decision quality for individuals exposed to a minority perspective. Moreover, minority influence targets with high horizontal individualism and low horizontal collectivism made higher quality decisions. Influence targets with high vertical collectivism demonstrated higher quality decisions when the influence agent held a high status position in the group. Results also demonstrate that influence agents with high vertical individualism experienced less role stress than those with low vertical individualism. Finally, influence agents with low role stress were more effective in influencing the decision making of others. We discuss our findings in terms of boundary conditions to the minority influence process.     

应激环境下亲社会性的增加：来自不同类型的亲社会偏好的研究证据

When Time Is Money: Decision Behavior under Opportunity-Cost Time Pressure

Decison-making dilemmas can arise because errors may result either from deciding too soon or from delaying decisions too long. Delay can result in lost opportunities or reductions in payoffs from the most accurate decision. This paper investigates decision processes in environments where there is time stress due to the opportunity cost of delaying decisions. First, using computer simulation, the relative accuracy of alternative decision strategies is examined in environments that differ in terms of the levels of opportunity cost of delay. The lexicographic choice rule is shown to be a very attractive decision process in situations where there is opportunity-cost time pressure. Two experiments test the adaptivity of actual decision behavior to the presence or absence of opportunity-cost time pressure along with variations in goals (accuracy emphasized vs. effort savings emphasized), dispersion in probabilities or weights across the outcomes of the choice options, and the degree of correlation among the outcomes. Subjects were generally adaptive to opportunity-cost time pressure. However, failures in adaptivity were identified when choice environment properties with conflicting implications for adaptation were present simultaneously. In particular, under opportunity-cost time pressure, subjects received a lower expected payoff when the goal was to emphasize choice accuracy than when the goal was to emphasize savings in effort. The question of when adaptivity in decision making might fail is discussed.
