Deciding the Fate of Others: The Cognitive Underpinnings of Racially Biased Juror Decision Making

In criminal law, jurors are supposed to ignore defendant race when considering factual matters of culpability. However, when judging the merits of a criminal case, jurors’ ability (or inability) to avoid bias may affect verdicts. Fact-based decision making expend cognitive resources, while heuristic-based decisions (e.g., using criminal stereotypes) conserve resources. Here, we investigated whether differences in cognitive resources and prejudice attitudes about Blacks influenced trial outcomes. We tested the impact of working memory capacity (WMC), cognitive load, prejudice, and target race (Black, White) on penalties ascribed to fictional criminal defendants in ambiguous-fact cases. Results showed that when “loaded,” prejudiced-low-WMC persons supported guilty verdicts with higher confidence more often for Black than White defendants. Conversely, regardless of WMC or prejudice attitude, participants penalized White defendants more often when not loaded. We suggest that cognitive resources and prejudice attitude influence fact-based decisions. Links to juror judgments and potential trial outcomes are discussed.     

When (and When Not) to Make Exceptions: Links among Age,Precedent Setting Decisions,and Argument Evaluation

Negative precedents are set when, in the absence of mitigating conditions, social rules are not enforced by relevant authorities. This study examined the effects of normative (i.e., to enforce rules) and nonnormative arguments (i.e., to “make exceptions”) on decisions that could establish negative precedents and whether those effects differed for children and adolescents. As expected, on baseline problems, age correlated positively with decision-making performance. After receiving normative arguments, normative decisions increased and adolescents—but not preadolescents—transferred their understanding to novel problems. Nonnormative arguments led to decrements in normative decisions across ages. However, only for preadolescents did performance decrements following nonnormative arguments transfer to novel problems. Discussion focuses on the abilities to engage in “metacognitive intercession,” variability in children’s and adolescents’ decisions, and developments in the understanding of the consequences of violating the social rules.     

Interests and Leadership among Adolescents

The purpose of this study was to ascertain whether there is a differential relationship in the socialization of children with respect to gender identification when responses of children were examined with respect to race and sex (N = 596 fifth and sixth grade boys and girls). Strong father preference was found to have no effect on the choice a boy will make when choosing between male and female peers, during preadolescence, while a strong mother preference by a girl is related to the sex of the peers she chooses. Preadolescent girls who identify with their mothers chose girls with whom to interact in a variety of activities more frequently than they chose boys. A greater proportion of girls preferred to engage in activities with their mothers than boys preferred to engage in activities with their fathers. No differences were observed between racial groups in terms of girls' choices involving peers. Black boys, however, preferred to engage in activities with opposite-sex rather than same-sex peers to a greater extent than white boys.     

Interpersonal Pattern Dynamics and Adaptive Behavior in Multiagent Neurobiological Systems: Conceptual Model and Data

ABSTRACT

Ecological dynamics characterizes adaptive behavior as an emergent, self-organizing property of interpersonal interactions in complex social systems. The authors conceptualize and investigate constraints on dynamics of decisions and actions in the multiagent system of team sports. They studied coadaptive interpersonal dynamics in rugby union to model potential control parameter and collective variable relations in attacker–defender dyads. A videogrammetry analysis revealed how some agents generated fluctuations by adapting displacement velocity to create phase transitions and destabilize dyadic subsystems near the try line. Agent interpersonal dynamics exhibited characteristics of chaotic attractors and informational constraints of rugby union boxed dyadic systems into a low dimensional attractor. Data suggests that decisions and actions of agents in sports teams may be characterized as emergent, self-organizing properties, governed by laws of dynamical systems at the ecological scale. Further research needs to generalize this conceptual model of adaptive behavior in performance to other multiagent populations.     

To Pass or Not to Pass: A Mathematical Model for Competitive Interactions in Rugby Union

ABSTRACT. Predicting behavior has been a main challenge in human movement science. An important step within the theory of coordination dynamics is to find out the rules that govern human behavior by defining order parameters and control parameters that support mathematical models to predict the behavior of a system. Models to describe human coordination have been focused on interlimb coordination and on interpersonal coordination in affiliative tasks but not on competitive tasks. This article aims to present a formal model with two attractors to describe the interactive behavior on a 2v1 system in rugby union. Interpersonal distance and relative velocity critical values were empirically identified and were included as task constraints that define the attractor landscape. It is shown that using relative velocity as a control parameter the model offers reasonable prediction concerning the decision-making process. The model has the plasticity to adapt to other settings where interpersonal distances and relative velocities amongst system components act as significant task constraints.     

Gender Roles,Suicide Attempts,and Substance Abuse

In this article, the focus is on a comparison of suicide attempts and substance abuse in the United States. It is argued that suicide attempts and substance abuse may function as psychologically equivalent but gender-specialized forms of self-injurious behaviors. Possible explanations for the gender segregation of suicide attempts and substance abuse are reviewed, and the benefits of crossover theories and treatments are presented.     

Hedonic Intensity of Disappointment and Elation

This research is an investigation of the hedonic intensities of elation and disappointment following the outcomes of risky gambles using two principles: disappointment aversion and the principle of limited emotion processing. Disappointment aversion implies a stronger impact of disappointment compared with elation; the principle of limited emotion processing predicts a smaller impact of elation if it occurs with a real gain, and a smaller impact of disappointment if it occurs with a real loss. Both principles support each other in the gain domain but operate against each other in the loss domain. It was predicted that disappointment would outweigh elation in the gain domain. For the loss domain, this question was left open to empirical scrutiny. Participants were provided with hypothetical gambles and were required to imagine having won, not won, lost, or not lost, money. Results supported the prediction for the gain domain; mixed results emerged for the loss domain. The model adds to the understanding of the cognitive and emotional processes following the outcomes of risky events.     

Threats to Democratic Rationality

This article examines trends that are impacting democratic rationality. It is found that the trends are almost uniformly negative. Viewed from within the legislative branch, trends are negatively impacting legislators’ time, complexifying problems, constraining options, and limiting the evaluation of options. Trends external to the legislative branch are reducing citizen participation and knowledge about public affairs, skewing the balance of power among the branches and states, and decreasing accountability of public officials. In combination, democratic rationality, the process of making good, efficient, and timely decisions to promote higher quality of life and the public good, is seriously threatened. Recommendations include public financing of campaigns, more structured legislative decision-making processes, simplification tests for all new legislation and regulations, and a major new initiative to foster public involvement in public decision making.     

Separating the confident from the correct: Leveraging member knowledge in groups to improve decision making and performance

Groups often struggle to distinguish expert members from others who stand out for various reasons but may not be particularly knowledgeable (Littlepage & Mueller, 1997). We examined an intervention designed to improve group decision making and performance through instructing group members to search for information they already possessed that was relevant to a problem. Participants estimated values and expressed their confidence in their estimates individually and then a second time either individually or in a group. This was done with or without the intervention. Results indicated that: (1) groups were more confident than, and out-performed, individuals, (2) group decision making was best captured by models predicting more influence for more accurate members when the intervention was used and more influence for more confident members in its absence, and (3) groups that received the intervention out-performed groups that did not.     

The Consequences and Correction of Inflation in Personal Savings Estimates in Specific Future Time Frames

We examined the consequences of personal savings estimate inflation that occurs when decision makers provide savings estimates for specific future months when compared with the next month or the next year time frames, along with a method to attenuate this bias. The results of three experiments showed that the savings estimate inflation leads to significantly larger estimates of desired nest egg size (Experiment 1) and preference for riskier choices in other financial domains such as investment and employment decisions (Experiment 2). An attempt to attenuate this bias revealed that it is corrected when individuals provide a budgeting estimate prior to giving a savings estimate (Experiment 3). The theoretical and practical implications of the findings are discussed. Copyright © 2012 John Wiley & Sons, Ltd.
