Sharing losses and sharing gains: Increased demand for fairness under adversity

There is ample experimental evidence showing that people have a strong preference for equity in wealth allocation and social interaction. Although the behavior of gain sharing and responses to (un)fairness in allocation of wealth has been extensively investigated in studies employing economic exchange games, few studies have focused on how people respond to an unfair division of loss between individuals. In this study we developed a new variant of the ultimatum game and examined the participants' reactions to (un)fairness in both gain and loss sharing. Results from three experiments showed that the rejection rates to unfair offers were generally higher in the loss than in the gain domain. Moreover, participants were inclined to associate loss with “unfair” and gain with “fair”, with stronger associations leading to higher rejection rates in the ultimatum game. Furthermore, in subjective rating, unfair offers were perceived as being more unfair in the loss than in the gain domain. These results demonstrate an increased demand for fairness under adversity and the importance of justice in liability sharing.     

Religious Appeals and Implicit Attitudes

This article explores the effects of religious appeals by politicians on attitudes and behavior. Although politicians frequently make religious appeals, the effectiveness of these appeals and the mechanisms of persuasion are unknown. This article explores the possibility that religious language can affect political attitudes through implicit processes. Because religious attachments are formed early in the lives of many Americans, religious language may influence citizens without their awareness. Implicit and explicit attitudes are related but distinct constructs, and implicit attitudes may have behavioral implications in the political realm. I test these hypotheses experimentally, relying on a widely used implicit measure, the Implicit Association Test. I find that a Christian religious appeal affects implicit attitudes and political behavior among people who currently or previously identify as Christian. Furthermore, an explicit preference for less religion in politics does not moderate implicit effects.     

Multi-attribute,multi-alternative models of choice: Choice,reaction time,and process tracing

The first aim of this research is to compare computational models of multi-alternative, multi-attribute choice when attribute values are explicit. The choice predictions of utility (standard random utility & weighted valuation), heuristic (elimination-by-aspects, lexicographic, & maximum attribute value), and dynamic (multi-alternative decision field theory, MDFT, & a version of the multi-attribute linear ballistic accumulator, MLBA) models are contrasted on both preferential and risky choice data. Using both maximum likelihood and cross-validation fit measures on choice data, the utility and dynamic models are preferred over the heuristic models for risky choice, with a slight overall advantage for the MLBA for preferential choice. The response time predictions of these models (except the MDFT) are then tested. Although the MLBA accurately predicts response time distributions, it only weakly accounts for stimulus-level differences. The other models completely fail to account for stimulus-level differences. Process tracing measures, i.e., eye and mouse tracking, were also collected. None of the qualitative predictions of the models are completely supported by that data. These results suggest that the models may not appropriately represent the interaction of attention and preference formation. To overcome this potential shortcoming, the second aim of this research is to test preference-formation assumptions, independently of attention, by developing the models of attentional sampling (MAS) model family which incorporates the empirical gaze patterns into a sequential sampling framework. An MAS variant that includes attribute values, but only updates the currently viewed alternative and does not contrast values across alternatives, performs well in both experiments. Overall, the results support the dynamic models, but point to the need to incorporate a framework that more accurately reflects the relationship between attention and the preference-formation process.     

Can confidence come too soon? Collective efficacy,conflict and group performance over time

Groups with a strong sense of collective efficacy set more challenging goals, persist in the face of difficulty, and are ultimately more likely to succeed than groups who do not share this belief. Given the many advantages that may accrue to groups who are confident, it would be logical to advise groups to build a high level of collective efficacy as early as possible. However, we draw on Whyte’s (1998) theory of collective efficacy and groupthink, to predict that when confidence emerges at a high level toward the beginning of a group’s existence, group members may be less likely to engage in process conflict; a form of conflict that may be beneficial in the early phase of a group project. We found support for this prediction in two longitudinal studies of classroom project teams.     

Right‐wing authoritarianism and social dominance orientation and the dimensions of generalized prejudice: A longitudinal test

A Dual Process Model (DPM) approach to prejudice proposes that there should be at least two dimensions of generalized prejudice relating to outgroup stratification and social perception, which should be differentially predicted by Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). The current study assessed the causal effects of SDO and RWA on three dimensions of prejudice using a full cross‐lagged longitudinal sample (N = 127). As expected, RWA, but not SDO, predicted prejudice towards ‘dangerous’ groups, SDO, but not RWA, predicted prejudice towards ‘derogated’ groups, and both RWA and SDO predicted prejudice towards ‘dissident’ groups. Results support previously untested causal predictions derived from the DPM and indicate that different forms of prejudice result from different SDO‐ and RWA‐based motivational processes.

Normativity and Desirability in Observational Assessments of Family Interaction

Issues of normativity (responding in a typical or average fashion) and desirability (the tendency for raters to endorse positive characteristics rather than neutral or more negative ones) are common in areas of the social sciences that frequently utilize profile correlations to measure dyadic similarity. They have implications for family scholars as well. In the present study, a pre‐existing data set was used to make an initial, though limited, investigation into potential confounds of normativity and desirability for macrolevel observational assessments of family interaction. An empirical example is presented using q‐sort ratings of family interaction, with variance in observational assessments decomposed into component parts. High levels of both normativity and desirability were found, indicating possible problems in terms of both reliability and validity of assessment. While the results provide an interesting beginning, they are limited due to the use of a q‐sort methodology as well as an instrument with limited background and use. These limitations are discussed, as well as alternative interpretations for normativity and desirability and implications for future research.     

Do people make decisions under risk based on ignorance? An empirical test of the priority heuristic against cumulative prospect theory

Brandstätter, Gigerenzer, and Hertwig [Brandstätter, E., Gigerenzer, G., & Hertwig, R. (2006). The Priority Heuristic: Making choices without trade-offs. Psychological Review, 113(2), 409–432] put forward the priority heuristic (PH) as a fast and frugal heuristic for decisions under risk. According to the PH, individuals do not make trade-offs between gains and probabilities, as proposed by expected utility models such as cumulative prospect theory (CPT), but use information in a non-compensatory manner and ignore information. We conducted three studies to test the PH empirically by analyzing individual choice patterns, decision times and information search parameters in diagnostic decision tasks. Results on all three dependent variables conflict with the predictions of the PH and can be better explained by the CPT. The predictive accuracy of the PH was high for decision tasks in which the predictions align with the predictions of the CPT but very low for decision tasks in which this was not the case. The findings indicate that earlier results supporting the PH might have been caused by the selection of decision tasks that were not diagnostic for the PH as compared to CPT.     

A new spin on losses looming larger than gains: asymmetric implicit associations from slot machine experience

Kahneman and Tversky's prospect theory states, among other things, that losses loom larger than gains. As much research as this simple idea has generated, key questions remain. How fundamental is the losses‐looming‐larger effect: will it emerge under more minimal circumstances than previously tested and will it manifest in implicit associations? And how does the actual experience of predominant losses or gains affect the losses‐looming‐larger effect? In two experiments employing non‐traditional methods, participants experienced slot machine spins in which symbols were paired with gain, loss, and neutral outcomes. After experiencing these pairings, participants took Implicit Association Tests (IATs). In Experiment 1, implicit associations formed by the minimal experience of the slot machine were lopsided: negative associations with the loss symbol were stronger than positive associations with the gain symbol. In addition, it was found that the extent to which losses loomed larger depended on the context of the slot machine experience, with losses looming implicitly larger than gains most when they were fewer in number (participants experienced a net‐gain) and least when they were the predominant outcome (participants experienced a net‐loss). Finally, in Experiment 2, a potential artifact was ruled out and a replication obtained by showing that slot machine losses implicitly loom larger whether conceptualized from the perspective of a casino player or a casino owner.
