The impact of risk and affect on information search efficiency

We develop and test a theoretical framework of the joint influence of risk and affect on information search efficiency. Our framework proposes that information search is less efficient (i.e., less strategic) when risk is high, versus low. It further proposes that the influences of positive and negative affect on search efficiency are asymmetric and depend on the level of risk. Negative affect improves search efficiency when risk is high, but not when it is low. Positive affect degrades search efficiency when risk is low, but not when it is high. We find results consistent with our framework in two experiments. We discuss implications for affect research and for decision making in risky contexts, including financial statement auditing.     

Emotion,Decision, and Risk: Betting on Gambles versus Betting on People

We examined the effects of two emotions, fear and anger, on risk‐taking behavior in two types of tasks: Those in which uncertainty is generated by a randomizing device (“lottery risk”) and those in which it is generated by the uncertain behavior of another person (“person‐based risk”). Participants first completed a writing task to induce fear or anger. They then made choices either between lotteries (Experiment 1) or between actions in risky two‐person decisions (Experiments 2 and 3). The experiments involved substantial real‐money payoffs. Replicating earlier studies (which used hypothetical rewards), Experiment 1 showed that fearful participants were more risk‐averse than angry participants in lottery‐risk tasks. However—the key result of this study—fearful participants were substantially less risk‐averse than angry participants in a two‐person task involving person‐based risk (Experiment 2). Experiment 3 offered options and payoffs identical to those of Experiment 2 but with lottery‐type risk. Risk‐taking returned to the pattern of Experiment 1. The impact of incidental emotions on risk‐taking appears to be contingent on the class of uncertainty involved. For lottery risk, fear increased the frequency of risk‐averse choices and anger reduced it. The reverse pattern was found when uncertainty in the decision was person‐based. Further, the effect was specifically on differences in willingness to take risks rather than on differences in judgments of how much risk was present. The impact of different emotions on risk‐taking or risk‐avoiding behavior is thus contingent on the type, as well as the degree, of uncertainty the decision maker faces.

Classroom-based cognitive-behavioral intervention to prevent aggression: Efficacy and social validity

Classroom teachers need effective, efficient strategies to prevent and/or ameliorate destructive student behaviors and increase socially appropriate ones. During the past two decades, researchers have found that cognitive strategies can decrease student disruption/aggression and strengthen pro-social behavior. Following preliminary pilot work, we conducted a study to determine whether a classwide, social problem-solving curriculum affected measures of knowledge and behavior for 165 4th and 5th grade students at risk for behavior problems. We found significant positive treatment effects on knowledge of problem-solving concepts and teacher ratings of aggression. Outcomes differed across teachers/classrooms, and there was no evidence that booster lessons affected treatment efficacy. Teacher ratings of social validity were generally positive. We discuss issues about classroom-based prevention research and future research directions.     

Factors influencing young children's risk of unintentional injury: Parenting style and strategies for teaching about home safety

This study examined mothers' teaching about home-safety issues to 24–30 month and 36–42 month old children, explored the relationship of teaching strategies to parenting styles, and assessed how these factors are related to children's risk of unintentional injury. A structured interview assessed home-safety issues relevant to falls, burns, cuts, poisoning, and suffocation/strangulation/choking. Mothers identified safety issues relevant to her child, and indicated the type and extent to which she utilized teaching as a strategy to address each safety issue. Standardized questionnaires provided information about parenting style and children's history of injuries. Results revealed that mothers' endorsements of home-safety issues did not vary with child age, mothers used teaching to manage safety issues for all types of injuries, and type of teaching strategy (explanations, rules, behavior modification) varied with parenting style. Greater use of explaining and less rule usage was linked to permissive parenting; these teaching strategies predicted children's medically-attended injury among highly-permissive mothers. Thus, teaching about safety is a common risk-management strategy mothers use to address hazards in the home. However, the specific type of teaching strategy used varies with parenting style, which has implications for children's risk of injury.     

Development and Validation of an Instrument for the Assessment of Dependency Among Bereaved Persons

Dependency among bereaved individuals has been hypothesized to be an important predictor of severe and enduring grief reactions. However, although there are a number of instruments that assess interpersonal dependency as a personality trait or style, no scales are available to assess bereavement-related dependency. Data from 170 widowed participants in a community-based longitudinal investigation, who had been bereaved for an average of 10.8 months, were used to investigate the reliability and validity of the Bereavement Dependency Scale (BDS), an instrument that was developed to assess dependency on the deceased among bereaved persons. Results indicated that the BDS demonstrated acceptable internal reliability and satisfactory convergent, discriminant, and construct validity. The BDS may be a clinically useful predictor of enduring and complicated grief reactions, major depressive disorder, and suicidality among recently bereaved individuals.     

The Mediating Role of Executive Functioning in the Relation Between Difficult Temperament and Physical Aggression

The present investigation tested the hypothesis that executive functioning (EF) would mediate the relation between difficult temperament (DT) and aggressive behavior. This model was tested in 310 adult men and women. DT was measured using the Dimensions of Temperament Scale—Revised, EF was measured using 7 well-established neuropsychological tests, and aggression was assessed using the Buss–Perry Aggression Questionnaire. EF successfully mediated the DT–aggression relation for men, however, the model did not hold for women. Results are discussed with regard to how they influence current models of aggressive behavior as well as their implications for future violence prevention efforts.     

Risk Perception and Affect

ABSTRACT— Humans perceive and act on risk in two fundamental ways. Risk as feelings refers to individuals' instinctive and intuitive reactions to danger. Risk as analysis brings logic, reason, and scientific deliberation to bear on risk management. Reliance on risk as feelings is described as "the affect heuristic." This article traces the development of this heuristic and discusses some of the important ways that it impacts how people perceive and evaluate risk.     

构建新型医患关系控制医院医疗风险

医疗风险普遍存在,医疗风险的控制就是在风险发生后,医方能及时、准确地采取各种措施,有效、经济地减少损害、弥补损失。针对医患双方在风险发生后有不同的心理特点,医院应该构建以病人为中心的、非惩罚的、和谐的医患关系,从而实现控制医疗风险的目的。     

医疗风险管理与医患关系的调适

医疗行为具有高风险属性,但医疗机构经营目标不是追求自身利益最大化,而是公众健康,因此医疗机构风险管理的手段和目标应该着眼于影响目标实现的各种不确定因素,这就要求把医患关系状况纳入风险管理范畴。在当前社会环境下,医疗机构自觉地自留一部分风险成本更有利于经营目标的实现和医患关系的协调。     

Different Pathways to Juvenile Delinquency: Characteristics of Early and Late Starters in a Sample of Previously Incarcerated Youth

We examined the differences between early and late start juvenile delinquents in a sample of 531 previously incarcerated youth in Oregon's juvenile justice system. Data were analyzed with logistic regression to predict early start delinquency based on four explanatory variables: foster care experience, family criminality, special education disability, and socioeconomic status. Youth with foster care experience were four times more likely to be early start delinquents than youth with no foster care experience. Youth with a family member convicted of a felony were two times more likely to be early start delinquents than youth with no family felony. Implications for future research are discussed, as well as implications for practice and policy. We suggest that future studies examine differences between male and female delinquents, the effects of foster care on children, and interfamilial processes that facilitate criminal behavior. Efforts to support children and families at risk of abuse and neglect should be reexamined in light of the results of our study, which adds to the emerging knowledge base regarding the relationships between violence experienced in early childhood, and future criminal behavior.
