Selective exposure and decision framing: The impact of gain and loss framing on confirmatory information search after decisions

When people make decisions, they often prefer to receive information that supports rather than conflicts with their decision. To date, this effect has mainly been investigated in the context of decisions about gains, whereas decisions about losses have received less attention. Based on Prospect Theory, we expected information search to be differently affected by whether people previously have decided about gains or losses. Three studies have revealed that selectivity of information search is stronger after gain-framed rather than after loss-framed decision problems. An investigation of the underlying psychological processes revealed that gain decisions are made with increased subjective decision certainty (i.e. they are easier and less effortful to make), which in turn systematically increases confirmatory information search.     

A New David Preparing for a New Goliath: A Question of Corporate Competence

Like the biblical David practicing his skill in defense of his flock, small companies are now gearing up their resident competencies in redesigning their organization in order to be flexible with changing needs. Like David, the day of facing Goliath may come without warning. This article tells the story of a small company engaged in rapid growth. The participative redesign of the organizational structure is presented as a narrative against the background of a simplified model of organizational design and the method of implementation. Key success factors are illustrated not only through anecdotes but also through measurements of results at the end of the first year.     

Decision-making processes: sensitivity to sequentially experienced outcome probabilities

A computerized sequential event sampling decision-making task was administered to 187 5- to 10-year-olds and adults Participants made a series of choices between alternatives that differed in win probability (Study 1) or win and loss probability (Study 2). Intuitive and more explicit measures were used. Study 1 revealed that, across ages, participants demonstrated intuitive sensitivity to probability; however, adult participants evidenced greater sensitivity than did children, and younger children failed to demonstrate more explicit understanding of probability. Study 2 also revealed that children were intuitively sensitive to probability; however, the inclusion of loss had limited impact on decision processes. These findings and their relevance to cognitive developmental theory are discussed.     

The pursuit of missing information in negotiation

A large body of research has focused on how people exchange and use information during the negotiation process. This work tends to treat information as if it all were readily available upon request. The current research investigated how delays in the pursuit of missing information can influence people’s ex-ante priorities and the final settlements they reach. Study 1 found that negotiators achieved more value on an issue after seeking missing information about that issue compared to when the same information was readily accessible. Study 2 found that the effect of searching for information on outcomes was mediated by changes in how important negotiators perceived the issue to be. Theoretical and practical implications are discussed.     

Diverse groups and information sharing: The effects of congruent ties

The impact of congruence between social and knowledge ties on performance in diverse groups was examined. Congruence occurs when group members who are socially tied share the same information and a stranger has any unique information. Incongruence occurs when group members who are socially tied possess different information, and one of them shares information with a stranger. In Experiment 1, three-person groups with congruent social and knowledge ties utilized information more effectively, reported more effective group processes, and outperformed groups with incongruent ties. Experiment 2, which involved four-person groups, examined the role of congruence in groups with either a single minority information holder or two equal-sized subgroups. Congruent groups again outperformed incongruent groups, but this was only true when groups had a minority information holder. There was no difference in the performance of congruent and incongruent groups that had equal-sized subgroups. The implications of these findings for analyses of group composition and decision-making are discussed.     

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.     

Leader-focused search: The impact of an emerging preference on information search

This article examines the influence an emerging preference (i.e., a leader) has on predecisional information search. We explore two possibilities. First, decision makers may seek information they expect will support their leader (leader-supporting search). Second, decision makers may seek information about their leader, irrespective of the expected valence of the information (leader-focused search). Across various studies, product domains and experimental designs, we consistently find that decision makers engage in leader-focused search, not leader-supporting search. We also find that leader-focused search can steer decision makers towards information sources that are less important, less credible, and objectively suboptimal.     

The Role of Family Processes and Coping Strategies in the Relationship Between Parental Chronic Illness and Childhood Internalizing Problems

Sixty-nine families (father, mother, and one child) in which the father had hemophilia, approximately half of whom were HIV positive, were assessed in an examination of the relationship between parental chronic illness, family functioning, child coping strategies, and child adjustment. Latent variable path analyses with partial least-squares estimation procedures (PLS) were used to test a model of the relationship between parental chronic illness, family process variables, child coping strategies, and child internalizing behavior problems. The severity of the father's illness predicted family process variables, which predicted the coping style of the child. The use of more avoidant coping strategies was associated with more internalizing problems.     

模拟网络信息主动增加特征的决策过程研究

与传统信息不同,网络信息具有可以主动增加的互动特征,本研究探讨这种特征对网络情境下决策加工过程的影响。通过改进的信息板技术追踪决策过程。实验一设置可否“主动增加信息”两种情境进行对照研究,发现引入主动增加功能后被试的搜索深度降低,先前知识的水平影响信息加工的模式;实验二设置可以连续要求增加信息的连续任务,比较不同的增加路径和选择阶段的影响,发现被试的搜索深度逐步降低,更多采用非补偿性的策略。两个实验均有超过半数的被试要求增加信息,连续任务有着32%的回头率,研究者推论在信息不断增加的情况下,被试的信息搜索行为更具选择性。     

The Evolutionary Challenge for Technology

The evolutionary challenge for technology in the third millennium is one of designing the vehicles for sustainable human and societal development in partnership with earth. The challenge calls for the conscious creation of evolutionary systems-not through the "hard technologies" that shape and mold the physical infrastructure of our planet, but through "soft technologies" that augment creative and constructive processes of human interaction. Through them, humanity has the opportunity to create the conditions for the emergence of a true learning society at both regional and global levels. The meaning of key terms such as evolution, technology, and development must be explored if we are to create a shared understanding of the contemporary survival challenges faced by humanity. This paper explores both the promise and the threat faced by a techno-civilization such as is emerging on our planet in the early twenty-first century.     

Enhancing adolescent girls’ argument skills in reasoning about personal and non-personal decisions

The present study sought to evaluate (a) the effectiveness of an intervention in developing adolescents’ argument skills regarding a decision on a topic of high potential personal relevance (teen pregnancy) or one of general social relevance (capital punishment), and (b) differential effects of the two topics in promoting the generalization of skills to a new topic. Thirty 14–15-year-old adolescent girls participated in an intervention on one of the two topics. The 16 sessions of the intervention were identical except for topic. Argument skills were assessed on both topics at pretest and posttest. Both interventions were effective in developing rudimentary argument skills, but only the intervention focusing on the personally relevant topic resulted in transfer to the less personal topic. Transfer in the opposite direction did not occur.     

A positive information logic for inferential information

Performing an inference involves irreducibly dynamic cognitive procedures. The article proposes that a non-associative information frame, corresponding to a residuated pogroupoid, underpins the information structure involved. The argument proceeds by expounding the informational turn in logic, before outlining the cognitive actions at work in deductive inference. The structural rules of Weakening, Contraction, Commutation, and Association are rejected on the grounds that they cause us to lose track of the information flow in inferential procedures. By taking the operation of information application as the primary operation, the fusion connective is retained, with commutative failure generating a double implication. The other connectives are rejected.     

The challenge of raising ethical awareness: A case-based aiding system for use by computing and ICT students

Students, the future Information and Communication Technology (ICT) professionals, are often perceived to have little understanding of the ethical issues associated with the use of ICTs. There is a growing recognition that the moral issues associated with the use of the new technologies should be brought to the attention of students. Furthermore, they should be encouraged to explore and think more deeply about the social and legal consequences of the use of ICTs. This paper describes the development of a tool designed to raise students’ awareness of the social impact of ICTs. The tool offers guidance to students undertaking computing and computer-related courses when considering the social, legal and professional implications of the actions of participants in situations of ethical conflict. However, unlike previous work in this field, this tool is not based on an artificial intelligence paradigm. Aspects of the theoretical basis for the design of the tool and the tool’s practical development are discussed. Preliminary results from the testing of the tool are also discussed. An earlier version of this paper was presented by one of the authors at the First International Conference on Teaching Applied and Professional Ethics in Higher Education, Federal University of Surrey Centre for Applied Ethics, Southlands College, Roehampton, London, 2–4 September, 2003.
