Dogmatism and predecisional information search.

Rokeach's Dogmatism Scale and 4 decision measures of tendencies to reserve judgment were administered to 72 freshmen women. A significant negative relationship was found between dogmatism and each of the 4 decision measures. The nondogmatic individual tended to delay decision and engage in predecisional search, to require more time for psychophysical judgments, and to respond "don't know" to statements of opinion under conditions of inadequate information. Accordingly, dogmatism was interpreted as a defense mechanism which interferes with processing of predecisional information. (16 ref.)

Understanding Pretrial Publicity: Predecisional Distortion of Evidence by Mock Jurors.

Prejudicial pretrial publicity (PTP) constitutes a serious source of juror bias. The current study examined differences in predecisional distortion for mock jurors exposed to negative PTP (N-PTP) versus nonexposed control participants. According to work by K. A. Carlson and J. E. Russo (2001), predecisional distortion occurs when jurors bias new evidence in favor of their current leading party (prosecution or defense) rather than evaluating this information for its actual probative properties. Jury-eligible university students (N=116) acted as jurors in a mock trial. Elevated rates of guilty verdicts were observed in the N-PTP condition. Predecisional distortion scores were significantly higher in the N-PTP condition and reflected a proprosecution bias. The effect of prejudicial PTP on verdict outcomes was mediated by predecisional distortion in the evaluation of testimony. Results are discussed in relation to motivated decision making and confirmation biases. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The aging decision maker: Cognitive aging and the adaptive selection of decision strategies.

Are older adults' decision abilities fundamentally compromised by age-related cognitive decline? Or can they adaptively select decision strategies? One study (N = 163) investigated the impact of cognitive aging on the ability to select decision strategies as a function of environment structure. Participants made decisions in either an environment that favored the use of information-intensive strategies or one favoring the use of simple, information-frugal strategies. Older adults tended to (a) look up less information and take longer to process it and (b) use simpler, less cognitively demanding strategies. In accordance with the idea that age-related cognitive decline leads to reliance on simpler strategies, measures of fluid intelligence explained age-related differences in information search and strategy selection. Nevertheless, both young and older adults seem to be equally adapted decision makers in that they adjust their information search and strategy selection as a function of environment structure, suggesting that the aging decision maker is an adaptive one.

Deliberative and implemental mind-sets: Cognitive tuning toward congruous thoughts and information.

Study 1 established either deliberative mind-set by having Ss contemplate personal change decision or implemental mind-set by having Ss plan execution of intended personal project. Ss were subsequently requested to continue beginnings of 3 fairy tales, each describing a main character with a decisional conflict. Analysis revealed that deliberative mind-set Ss ascribed more deliberative and less implementational efforts to main characters than implemental mind-set Ss. In Study 2, Ss were asked to choose between different test materials. Either before or after making their decision, Ss were given information on deliberative and implementational thoughts unrelated to their task at hand. When asked to recall these thoughts, predecisional Ss recalled more deliberative and less implementational thoughts, whereas for postdecisional Ss the reverse was true. These findings suggest that deliberative and implemental mind-sets tune thought production and information processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Processing speed and memory mediate age-related differences in decision making.

Decision making under risk changes with age. Increases in risk aversion with age have been most commonly characterized, although older adults may be risk seeking in some decision contexts. An important, and unanswered, question is whether these changes in decision making reflect a direct effect of aging or, alternatively, an indirect effect caused by age-related changes in specific cognitive processes. In the current study, older adults (M = 71 years) and younger adults (M = 24 years) completed a battery of tests of cognitive capacities and decision-making preferences. The results indicated systematic effects of age upon decision quality—with both increased risk seeking and increased risk aversion observed in different tasks—consistent with prior studies. Path analyses, however, revealed that age-related effects were mediated by individual differences in processing speed and memory. When those variables were included in the model, age was no longer a significant predictor of decision quality. The authors conclude that the reduction in decision quality and associated changes in risk preferences commonly ascribed to aging are instead mediated by age-related changes in underlying cognitive capacities.

Threat and selective exposure: The moderating role of threat and decision context on confirmatory information search after decisions.

Previous studies on the impact of perceived threat on confirmatory information search (selective exposure) in the context of decision making have yielded mixed results. Some studies have suggested that confirmatory information search is reduced, yet others have found contradictory effects. The present series of 5 studies consistently found that the crucial moderator for these inconsistent findings was whether the induced threat was contextually related to the subsequent decision and information search tasks. Contextual incongruence (e.g., an induction of terrorist threat followed by an economic decision case) results in reduced levels of confirmatory information search, whereas a congruent threat (e.g., an induction of terrorist threat followed by a decision case on terrorism) results in increased levels of confirmatory information search. Analyses of the underlying psychological processes revealed that decision-unrelated threat inductions increase decision makers' experienced decision uncertainty, thus reducing confirmatory information search.

Following your heart or your head: Focusing on emotions versus information differentially influences the decisions of younger and older adults.

[Correction Notice: An erratum for this article was reported in Vol 16(2) of Journal of Experimental Psychology: Applied (see record 2010-12508-005). The wrong author order was listed. The correct order is presented in the erratum.] Research on aging has indicated that whereas deliberative cognitive processes decline with age, emotional processes are relatively spared. To examine the implications of these divergent trajectories in the context of health care choices, we investigated whether instructional manipulations emphasizing a focus on feelings or details would have differential effects on decision quality among younger and older adults. We presented 60 younger and 60 older adults with health care choices that required them to hold in mind and consider multiple pieces of information. Instructional manipulations in the emotion-focus condition asked participants to focus on their emotional reactions to the options, report their feelings about the options, and then make a choice. In the information-focus condition, participants were instructed to focus on the specific attributes, report the details about the options, and then make a choice. In a control condition, no directives were given. Manipulation checks indicated that the instructions were successful in eliciting different modes of processing. Decision quality data indicate that younger adults performed better in the information-focus than in the control condition whereas older adults performed better in the emotion-focus and control conditions than in the information-focus condition. Findings support and extend extant theorizing on aging and decision making as well as suggest that interventions to improve decision-making quality should take the age of the decision maker into account.

Intergroup competition for the provision of binary public goods.

An experimental paradigm is proposed for investigating interpersonal conflicts under conditions of intergroup competition. The paradigm constitutes an n-person game with imperfect and incomplete information in which the n players are divided into two groups, are each assigned monetary endowment, and must then decide independently and anonymously whether to keep the endowment or contribute it to the group's benefit. The group with the larger sum of contributions is provided with a monetary reward (binary public good), which is shared equally among all of its members regardless of their decision. Two alternative models are proposed and their testable implications are derived and discussed. Both assume maximization of expected utility, but their assumptions about the expectations each player holds about the decisions of the remaining players are different. The effects of predecisional communication are examined and several extensions of the basic paradigm are outlined. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Aging and decision making: driving-related problem solving

We examined age-related effects on decision making in a task environment familiar to most younger and older adults. Participants made route-selection decisions in real time. Participants received information about traffic density and expected speed limits of main and alternative routes, from which they determined the optimality of their present route versus alternative routes. The experiment evaluated the effects of information type, amount of congestion, alternative route speed limit, and age on speed and quality of decision making. Measures of optimal route selection revealed main effects of alternative route speed limit, congestion level, and message type, but there was not a main effect of age, and age did not interact with any variable. In terms of decision speed (but not quality of decision making), older participants were slower, and age interacted with alternative route speed and with message type. The data are interpreted in relation to previous data examining everyday problem solving and aging.

A signal-detection analysis of fast-and-frugal trees.

Models of decision making are distinguished by those that aim for an optimal solution in a world that is precisely specified by a set of assumptions (a so-called “small world”) and those that aim for a simple but satisfactory solution in an uncertain world where the assumptions of optimization models may not be met (a so-called “large world”). Few connections have been drawn between these 2 families of models. In this study, the authors show how psychological concepts originating in the classic signal-detection theory (SDT), a small-world approach to decision making, can be used to understand the workings of a class of simple models known as fast-and-frugal trees (FFTs). Results indicate that (a) the setting of the subjective decision criterion in SDT corresponds directly to the choice of exit structure in an FFT; (b) the sensitivity of an FFT (measured in d′) is reflected by the order of cues searched and the properties of cues in an FFT, including the mean and variance of cues' individual d′s, the intercue correlation, and the number of cues; and (c) compared with the ideal and the optimal sequential sampling models in SDT and a majority model with an information search component, FFTs are extremely frugal (i.e., do not search for much cue information), highly robust, and well adapted to the payoff structure of a task. These findings demonstrate the potential of theory integration in understanding the common underlying psychological structures of apparently disparate theories of cognition.

Making choices impairs subsequent self-control: A limited-resource account of decision making, self-regulation, and active initiative.

The current research tested the hypothesis that making many choices impairs subsequent self-control. Drawing from a limited-resource model of self-regulation and executive function, the authors hypothesized that decision making depletes the same resource used for self-control and active responding. In 4 laboratory studies, some participants made choices among consumer goods or college course options, whereas others thought about the same options without making choices. Making choices led to reduced self-control (i.e., less physical stamina, reduced persistence in the face of failure, more procrastination, and less quality and quantity of arithmetic calculations). A field study then found that reduced self-control was predicted by shoppers' self-reported degree of previous active decision making. Further studies suggested that choosing is more depleting than merely deliberating and forming preferences about options and more depleting than implementing choices made by someone else and that anticipating the choice task as enjoyable can reduce the depleting effect for the first choices but not for many choices.

Team reflexivity, development of shared task representations, and the use of distributed information in group decision making.

Decision-making groups often exchange and integrate distributed information to a lesser extent than is desirable for high-quality decisions. One important reason for this lies in group members’ understanding of the decision task—their task representations—specifically the extent to which they understand the importance of exchange and integration of information. The authors hypothesized that a group’s development of a (shared) understanding of the information elaboration requirements of their task is influenced by collective reflection on the task. When not all group members initially realize the importance of information elaboration, team reflexivity increases the degree to which the group understands the importance of information elaboration. In an experiment, the authors showed that team reflection fostered the development of task representations emphasizing information elaboration and subsequent information elaboration and decision quality. When all members initially already held representations emphasizing information elaboration, team reflection promoted elaboration and performance to a lesser degree.

Judgments about judgments: The dissociation of consideration price and transaction commitment judgments.

There are many contexts in which people make judgments about prior judgments. For example, Internet shopping bots (e.g., NexTag.com) allow consumers to search for products and, if the price is too high, list a price at which they would consider making the purchase (i.e., base judgment). If the price drops to this level, the vendor generates an e-mail inviting the consumer to execute the transaction at the reduced price (i.e., contingent judgment). The authors show that the consideration price depends on the content of retrieved information, whereas the willingness to execute the transaction at the consideration price depends on the ease-of-retrieving the information. The authors use different offer prices to encourage the consumer to retrieve information consistent with different product quality levels. The authors also select offer prices so that information retrieval is more difficult at moderate offer prices than at high or low offer prices. Accordingly, the authors show that the consideration price increases as the offer price increases, but the willingness to execute the transaction at the consideration price is greater when there are high and low, as opposed to moderate, offer prices.

Group negotiation: Effects of decision rule, agenda, and aspiration.

In this study we characterized small group negotiation as a mixed motive task that involved both cooperation and competition. We examined the impact of two group decision-making processes (decision rule and agenda) and one cognitive-motivational frame (aspiration level) on the quality of negotiated outcomes in small groups. Negotiation groups that used a unanimous decision rule were more likely to integrate their interests to achieve higher group outcomes than were groups that used a majority rule. Negotiation groups that followed an explicit agenda and used a majority decision rule distributed resources more unequally, and were more likely to form coalitions against a remaining party than were groups with no agenda/majority rule, explicit agenda/unanimity rule, and no agenda/unanimity rule. There was no support for the hypotheses that group members who held high aspirations and followed a majority decision rule would distribute resources more unequally than would groups with high aspirations/unanimity rule, low aspirations/majority rule, and low aspirations/unanimity rule; that adherence to explicit agendas would lead to lower group profits; and that the absence of high aspirations would lead to lower group profit. We discuss the results in terms of a mixed motive analysis of group decision making. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

It's Good to Be Leader: The Influence of Randomly and Systematically Selected Leaders on Decision-Making Groups.

Research on hidden profiles reveals that groups often have trouble utilizing unshared information and making the optimal decision in decision-making contexts. However, a directive group leader advocating the best decision can help a group overcome this problem. The current study examines how a leader's access to information affects the quality of group decisions and information sharing. In addition, how leader selection processes affect leader influence is considered. Overall, evidence is found indicating a leader's access to information and leader selection processes influence group discussions and decision quality.

Aging, source memory, and emotion.

In 2 experiments we assessed younger and older adults' ability to remember contextual information about an event. Each experiment examined memory for 3 different types of contextual information: (a) perceptual information (e.g., location of an item); (b) conceptual, nonemotional information (e.g., quality of an item); and (c) conceptual, emotional information (e.g., safety of an item). Consistent with a large literature on aging and source memory, younger adults outperformed older adults when the contextual information was perceptual in nature and when it was conceptual, but not emotional. Age differences in source memory were eliminated, however, when participants recalled emotional source information. These findings suggest that emotional information differentially engages older adults, possibly evoking enhanced elaborations and associations. The data are also consistent with a growing literature, suggesting that emotional processing remains stable with age (e.g., Carstensen & Turk-Charles, 1994, 1998; Isaacowitz, Charles, & Carstensen, 2000).

Affect regulation and temporal discounting: Interactions between primed, state, and trait affect.

Previous research has largely focused on the influence of experienced affect on decision making; however, other sources of affective information may also shape decisions. In two studies, we examine the interacting influences of affective information, state affect, and personality on temporal discounting rates (i.e., the tendency to choose small rewards today rather than larger rewards in the future). In Study 1, participants were primed with either positive or negative affect adjectives before making reward choices. In Study 2, participants underwent either a positive or negative affect induction before making reward choices. Results in both studies indicate that neuroticism interacts with state unpleasant affect and condition (i.e., positive or negative primes or induction) to predict discounting rates. Moreover, the nature of the interactions depends on the regulatory cues of the affective information available. These results suggest that irrelevant (i.e., primes) and stable (i.e., personality traits) sources of affective information also shape judgments and decision making. Thus, current affect levels are not the only source of affective information that guides individuals when making decisions. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
