Stopping rule use during information search in design problems

Information search is critical in most decision-making tasks. An important aspect of information search is the stopping rule used by the decision maker to terminate information acquisition. Decision-making problems may be usefully decomposed into design problems and choice problems. The distinction is critical because the goals of stopping behavior in the two types of problems are quite different. In design problems, the focus is on the sufficiency of information obtained for problem structuring and generating alternatives, while choice problems focus on convergence toward a solution. While previous research has studied stopping behavior in choice problems, the present research is concerned with stopping rule use during information search in design problems. To build theory in this area, we conducted two experiments. In the first, we presented professional systems analysts with an information search problem in a systems development context and asked them to gather information for a proposed system. Protocols of the search sessions were analyzed, and stopping rules used and information gathered by the analysts were identified. Results indicated that the use of certain stopping rules resulted in greater quantity and quality of information gathered. Additionally, stopping rule use, rather than analyst experience, accounted for the quantity and quality of information elicited. Finally, stopping rule use differed between more experienced and less experienced analysts. To apply our findings about stopping rules from the first experiment, we performed a second experiment in which we investigated stopping rule use in a consumer information search task on the world wide web. Results indicated the use of the same stopping rules as in the first experiment, although in different proportions. Implications for information search theory and practice are discussed.     

Ending homelessness. Policy challenges.

The extent and nature of homelessness is discussed. Only after understanding these parameters was the federal government able to develop an appropriate homelessness policy, including an explicit goal to help end, rather than simply address, the problem. The article describes how, with increased information, federal programs for the homeless have evolved, beginning with emergency remedies and shifting to more permanent solutions. Significantly increased cooperation at federal, state, and local levels is called for to effectively address this multifaceted problem. In the long term, we must wage a broad attack on poverty if we are to eradicate the root problems that force people into homelessness.     

The Influence of External Recruitment Practices on Job Search Practices Across Domestic Labor Markets: A comparison of the United States and China

Job search theories traditionally assume that job seekers have open access to information about employment opportunities. This may be moderated by the degree that labor markets rely on external recruitment to convey information about employment opportunities. In particular, external recruitment may be more widely used in some countries than other countries. Accordingly, this paper hypothesizes that job search practices that rely on external recruitment and information sharing with potential recruits are more likely to be widely used in the United States than in China and that job search practices are more likely to influence starting wages in the United States than in China. Using samples of graduating undergraduate college students in both the United States and China, this study suggests that job seekers gather more information about employment opportunities in the United States than in China, and that job search effort is more likely to influence starting wages in the United States than in China. The research suggests that job search theories need to consider job seeker access to information as a significant moderating variable in job search theory.     

Criterial problems in creative cognition research

In creative cognition research, the Romantic view about creative cognition is traditionally rejected in favor of the modern view. The modern view about creative cognition maintains that creativity is neither mysterious nor unintelligible and that it is indeed susceptible to analysis. The paradigmatic objects of analysis in creative cognition research have been creative output and the creative process. The degree of creativity of an output is assessed in accordance with certain criterial definitions. The degree of creativity of a cognitive process is assessed in accordance with certain models of creative cognition, psychometric test measures, and neuroimaging studies that are grounded in certain criteria for assessment. The reliance on criterial definitions and criteria for assessment in analyzing either the creative output or the creative process suggests that creative cognition researchers remain under the sway of the classical, bundles-of-criteria theory of meaning. In this paper, I will critically evaluate the criterial problems that confront both criterial definitions and criteria for assessment before proposing an alternative theory of meaning.     

Information Processing Strategies in Riskless Preference Reversals: The Prominence Effect

A preference reversal occurs whenever an individual prefers one alternative to another in one response mode (e.g., choice) but shows the opposite preference order in another response mode (e.g., attractiveness ratings, matching). In previous studies of riskless multiattribute preferences the most common reversal pattern involves a prominence effect: The more important attribute has a greater influence in choices than in matching judgments. Previous research has suggested that the prominence effect can be accounted for by the strategy compatibility principle, which states that response tasks can evoke different decision strategies and these strategies determine the relative impact of the various attributes. This article attempts to establish the mediating role of decision processes in determining the occurrence and pattern of riskless preference reversals. In a process tracing experiment we replicate previous findings of a prominence effect in riskless two-attribute preferences. In addition, there are clear differences in process between response modes, and these differences are consistent with previous explanations of riskless preference reversals. Finally, we are able to predict subject level differences in choice preferences and choice versus matching reversals using measures of information search.     

Meaning-Making in Delayed-Return Cultures: The Case of Personal Uncertainty

The large majority of humans nowadays live in cultures in which there is often a delay between the efforts they exert and the feedback they receive regarding the outcome of their efforts. As a result, individuals may experience uncertainty between their efforts and outcomes, leading them to pay special attention to uncertainty information. In particular, we propose that when people feel uncertain about themselves, this may be alarming to them as it may signal that their personal contract with their delayed-return culture may be in jeopardy. Therefore, under conditions of personal uncertainty, people are looking forward to events that bolster their cultural worldviews and detest events that violate these worldviews. We review research findings that show that personal uncertainty indeed has a special role in the social psychology of meaning-making and worldview defense, sometimes even yielding a better explanation of worldview defense reactions than terror management theory.     

Self‐Directed Learning Favors Local,Rather Than Global,Uncertainty

Collecting (or “sampling”) information that one expects to be useful is a powerful way to facilitate learning. However, relatively little is known about how people decide which information is worth sampling over the course of learning. We describe several alternative models of how people might decide to collect a piece of information inspired by “active learning” research in machine learning. We additionally provide a theoretical analysis demonstrating the situations under which these models are empirically distinguishable, and we report a novel empirical study that exploits these insights. Our model‐based analysis of participants' information gathering decisions reveals that people prefer to select items which resolve uncertainty between two possibilities at a time rather than items that have high uncertainty across all relevant possibilities simultaneously. Rather than adhering to strictly normative or confirmatory conceptions of information search, people appear to prefer a “local” sampling strategy, which may reflect cognitive constraints on the process of information gathering.     

Wage comparisons with similar and dissimilar others

Considerable research has been completed on the link between social comparisons and employee satisfaction. Surprisingly, however, few of those studies contrast the effects of various comparisons with others on pay satisfaction. Based on social comparison theory, we expected that comparisons with similar others would be more important predictors of pay satisfaction than comparisons with dissimilar others. Across four studies, the degree of similarity of the comparison other was varied. In Studies 1 and 2, respondents made pay comparisons inside or outside the organization. In Studies 3 and 4, respondents made pay comparisons with referents in the same and different occupations. In all four studies we found that while similar others did provide employees with important information that affected their satisfaction, so did information about dissimilar others. We suggest that the importance of a job in our self‐definitions, with pay level being among the most overt markers, may account for our findings. Using pay as a yardstick may lead us all to widen our search for information about others, including ordinarily discrepant others. Alternative explanations and directions for research are discussed.     

Career indecision: Three factors from decision theory

Three factors of indecision are derived from decision theory: being insufficiently informed about the alternatives, valuation problems, and uncertainty about the outcomes. The three factors are studied in high school students’ career decision process of choosing further studies. Using factor analysis, we found empirical evidence for a differentiation between the three theoretical sources of career indecision: an information factor, a valuation factor, and an outcomes factor, but only the valuation factor and the outcomes factor seem to associate empirically with career indecision. The importance of both factors for career indecision was further supported by their intermediate role between general indecisiveness and career indecision.     

Age and gender differences in adolescent worry

The purpose of the present study was to explore gender and age differences in adolescent worry. High school students filled out measures of worry, negative problem orientation, intolerance of uncertainty, and general mental health. Girls and boys of different ages were then compared and the relationships between gender, beliefs about worry, intolerance of uncertainty, negative problem orientation and mental health were also examined. Boys reported greater negative problem orientation and intolerance of uncertainty while girls reported more positive beliefs about worry. Findings also revealed certain age trends, indicating that the variables under study may be under the influence of developmental tasks. Regression analysis was performed and positive beliefs about worry emerged as a significant predictor of worry in both sexes. Positive beliefs about worry and negative problem orientation appear to be the key processes in adolescent anxiety and depression.     

“Piensa” twice: On the foreign language effect in decision making

In this article, we assess to what extent decision making is affected by the language in which a given problem is presented (native vs. foreign). In particular, we aim to ask whether the impact of various heuristic biases in decision making is diminished when the problems are presented in a foreign language. To this end, we report four main studies in which more than 700 participants were tested on different types of individual decision making problems. In the first study, we replicated Keysar et al.’s (2012) recent observation regarding the foreign language effect on framing effects related to loss aversion. In the second section, we assessed whether the foreign language effect is present in other types of framing problems that involve psychological accounting biases rather than gain/loss dichotomies. In the third section, we studied the foreign language effect in several key aspects of the theory of decision making under risk and uncertainty. In the fourth study, we assessed the presence of a foreign language effect in the cognitive reflection test, a test that includes logical problems that do not carry emotional connotations. The absence of such an effect in this test suggests that foreign language leads to a reduction of heuristic biases in decision making across a range of decision making situations and provide also some evidence about the boundaries of the phenomenon. We explore several potential factors that may underlie the foreign language effect in decision making.     

When curiosity killed regret: Avoiding or seeking the unknown in decision-making under uncertainty

In two experimental studies we investigated how curiosity and regret aversion affect decision-making under uncertainty. Building on insights derived from information-gap theory [Loewenstein, G. (1994). The psychology of curiosity: a review and reinterpretation. Psychological Bulletin, 116, 75-98], we demonstrate that curiosity may overcome regret aversion. In Experiment 1, we concentrate on the reluctance to opt for alternatives with uncertain outcomes and demonstrate that curiosity about the uncertain outcomes may override regret aversion. In Experiment 2, we focus on reluctance to expose oneself to potential regret-inducing information and demonstrate that curiosity may overcome this reluctance.     

Promoting Consumer Adoption of High‐Technology Products: Is More Information Always Better?

An important challenge for firms commercializing technology‐based new products is to reduce consumers' perceptions of performance uncertainty. We build on prior research in consumer decision making and acceptance of high‐technology products and focus on the role of information in influencing perceptions of performance uncertainty of new product interfaces. In contrast to prior literature, we show here that more information is not always better in reducing performance uncertainty. We argue that the effects of more (vs. less) information on the performance uncertainty of a new interface and consumer adoption intentions of the new product are moderated by the degree of newness of the particular functionality (i.e., set of potential benefits) that is delivered by the new product. We report two experiments that investigate this problem and show that more information helps to reduce performance uncertainty only when the product provides a preexisting functionality. However, high levels of information about the new interface actually intensify performance uncertainty when the product delivers a new functionality. We conclude with a discussion of the theoretical and managerial implications of the findings.     

Information Seeking Beyond Initial Interaction.

This essay extends previous work on uncertainty and information seeking within close relationships by considering how relationship parameters correspond with the directness of people's information‐seeking strategies. Because we believe that assumptions of uncertainty reduction theory (Berger & Calabrese, 1975) have been translated into the context of close relationships without attention to the unique features of that domain, we begin by reframing questions about uncertainty to reflect issues relevant to intimate associations. In particular, we reconsider the focus of uncertainty, the function of uncertainty reduction, and the nature of information seeking. We then discuss how relationship intimacy, power dynamics, and information expectancies correspond with information‐seeking behavior within close relationships. In doing so, we highlight how the negotiation of relational uncertainty may function to sustain intimate associations.     

How choice ecology influences search in decisions from experience

Research into human decision-making has often sidestepped the question of search despite its importance across a wide range of domains such as search for food, mates, allies, visual targets or information. Recently, research on decisions from experience has made progress in finding out how individual characteristics shape search for information. Surprisingly little is known, however, about how the properties of the choice ecology shape people's search. To fill this void, we analyzed how two key ecological properties influence search effort: domain of choice (gains vs. losses) and experienced variance (variance vs. no variance). Many people search longer when facing the prospect of losses relative to gains. Moreover, most people search more in options in which they experience variance relative to options they experience as invariant. We conclude that two factors that have been identified as important determinants of choice also influence search of information.     

The influence of mood on the search for supporting versus conflicting information: dissonance reduction as a means of mood regulation?

Focusing on similarities between the mood regulation approach and dissonance theory, this article addresses the interplay between dissonance and mood by examining how individuals search for information after making a decision while under the influence of positive versus negative mood. Study 1 suggested that negative mood increased the preference for consonant over dissonant information after decisions, whereas positive mood led to a more balanced information search. In Study 2, participants in negative mood rated consonant information as more pleasant and dissonant information as more annoying than participants in positive mood. In addition, the results suggested that mood regulation processes took place. In Study 3, the findings from Study 1 were replicated with a paradigm in which higher stakes were involved.     

Need for closure and dealing with uncertainty in decision making context: The role of the behavioral inhibition system and working memory capacity

The aim of the present study was to investigate the moderated mediation model of the relationship between the behavioral inhibition system (BIS), need for closure (NFC) and working memory capacity (WMC) in the decision making process. It was assumed that NFC works as a motivational mechanism that enables individuals high in BIS to deal with uncertainty; therefore, NFC mediates the effect of BIS on behavior in a decision-making situation. Moreover, as uncertainty management requires cognitive resources, we expected WMC to moderate this relationship. In line with our hypothesis, we found that NFC mediated the relationship between BIS and the information search about the job candidates, and this effect occurred only for individuals high in WMC. We discuss these results in the context of effective self-regulation, as well as motivational and cognitive determinants of effort.     

Evidence for Implicit Risk: Delay Facilitates the Processing of Uncertainty

Humans and other animals discount the value of rewards over time. One explanation for this is that delayed rewards may be less certain than immediate rewards, what has been referred to as the implicit risk hypothesis. Although this explanation is widely accepted, little research has directly assessed the validity of the implicit risk hypothesis. In the current study, we present two experiments in which participants made decisions about rewards involving both delay and uncertainty. By manipulating the order in which information was presented, we were able to investigate whether delay information facilitates beliefs about uncertainty and vice versa. It was found that participants were more likely to prefer larger, delayed rewards when information about delay was presented before information about uncertainty than when the information was presented in the opposite order. Additionally, we describe a process model that implements the implicit risk hypothesis and show that it is consistent with the observed patterns of data. These results support the implicit risk hypothesis and suggest that information about delay facilitates the processing of information about uncertainty. Copyright © 2015 John Wiley & Sons, Ltd.     

生命性在句子加工中作用的ERP研究

生命性广泛地渗透到人类语言系统中发挥其作用。本文主要结合最新和经典的有关生命性的ERP研究探讨了生命性信息起作用的模式和时间进程。在句子加工过程中,生命性影响论元的加工并影响题元结构的建构和解释。以往研究表明,生命性违反有时引发的是N400效应,有时引发的是P600效应,少数情况还表现出N400-P600的双相模式。生命性在句子加工中的作用还跟多种变量存在交互作用,语境、题元可逆性、论元之间的语义关系、动词类型和其固有的题元结构都可能影响生命性信息起作用的模式。文章最后进行总结和展望,并提出未来研究仍有必要继续探讨生命性信息加工的时间神经动态性及其在句子加工中的具体作用机制。
