Visualizing risky situations induces a stronger neural response in brain areas associated with mental imagery and emotions than visualizing non-risky situations

In an fMRI study, we tested the prediction that visualizing risky situations induces a stronger neural response in brain areas associated with mental imagery and emotions than visualizing non-risky and more positive situations. We assumed that processing mental images that allow for “trying-out” the future has greater adaptive importance for risky than non-risky situations, because the former can generate severe negative outcomes. We identified several brain regions that were activated when participants produced images of risky situations and these regions overlap with brain areas engaged in visual, speech, and movement imagery. We also found that producing images of risky situations, in contrast to non-risky situations, was associated with increased neural activation in the insular cortex and cerebellum–the regions involved, among other functions, in emotional processing. Finally, we observed an increased BOLD signal in the cingulate gyrus associated with reward-based decision making and monitoring of decision outcomes. In summary, risky situations increased neural activation in brain areas involved in mental imagery, emotional processing, and decision making. These findings imply that the evaluation of everyday risky situations may be driven by emotional responses that result from mental imagery

The impact of death awareness on sizes of self-representational objects

People seem to have a tendency to increase the relative size of self-representational objects. Prior research suggests that motivational factors may fuel that tendency, so the present research built from terror management theory to examine whether existential motivations—engendered by concerns about death—may have similar implications for self-relevant size biases. Specifically, across two studies (total N = 288) we hypothesized that reminders of death would lead participants to inflate the size of self-representational objects. Both studies suggested that relative to reminders of pain, mortality salience led participants to construct larger clay sculptures of themselves (vs. others; Study 1) and a larger ostensible video-game avatar for the self (vs. others; Study 2)

Work, love, and death thought accessibility: a terror management investigation

Terror management theory suggests that following culturally derived scripts for valued behaviour protects people from death concerns, and conversely, not meeting standards for cultural value can weaken this protection, heightening mortality concerns. Using this conceptual framework we examine (1) how considerations of loss of employment, a source of cultural value for many, relates to the accessibility of death-related cognition, and (2) the moderating role of job market health and (3) involvement in close relationships. Study 1 found that writing about being unemployed (vs. a control topic) led to greater mortality-related cognition. Study 2 found that considering unemployment heightened death-cognition, but only when participants were led to perceive the job market as unhealthy. Finally, Study 3 found that considering unemployment led to greater death-cognition, but not for those involved in a close relationship. Findings offer insight into a previously overlooked consequence of unemployment, and factors that may serve a protective function

A Review of Risk Perceptions and Other Factors that Influence Flood Mitigation Behavior

In flood risk management, a shift can be observed toward more integrated approaches that increasingly address the role of private households in implementing flood damage mitigation measures. This has resulted in a growing number of studies into the supposed positive relationship between individual flood risk perceptions and mitigation behavior. Our literature review shows, however, that, actually, this relationship is hardly observed in empirical studies. Two arguments are provided as an explanation. First, on the basis of protection motivation theory, a theoretical framework is discussed suggesting that individuals’ high-risk perceptions need to be accompanied by coping appraisal to result in a protective response. Second, it is pointed out that possible feedback from already-adopted mitigation measures on risk perceptions has hardly been considered by current studies. In addition, we also provide a review of factors that drive precautionary behavior other than risk perceptions. It is found that factors such as coping appraisal are consistently related to mitigation behavior. We conclude, therefore, that the current focus on risk perceptions as a means to explain and promote private flood mitigation behavior is not supported on either theoretical or empirical grounds

Competition and moral behavior: A meta-analysis of forty-five crowd-sourced experimental designs

Significance Using experiments involves leeway in choosing one out of many possible experimental designs. This choice constitutes a source of uncertainty in estimating the underlying effect size which is not incorporated into common research practices. This study presents the results of a crowd-sourced project in which 45 independent teams implemented research designs to address the same research question: Does competition affect moral behavior? We find a small adverse effect of competition on moral behavior in a meta-analysis involving 18,123 experimental participants. Importantly, however, the variation in effect size estimates across the 45 designs is substantially larger than the variation expected due to sampling errors. This “design heterogeneity” highlights that the generalizability and informativeness of individual experimental designs are limited. Abstract Does competition affect moral behavior? This fundamental question has been debated among leading scholars for centuries, and more recently, it has been tested in experimental studies yielding a body of rather inconclusive empirical evidence. A potential source of ambivalent empirical results on the same hypothesis is design heterogeneity—variation in true effect sizes across various reasonable experimental research protocols. To provide further evidence on whether competition affects moral behavior and to examine whether the generalizability of a single experimental study is jeopardized by design heterogeneity, we invited independent research teams to contribute experimental designs to a crowd-sourced project. In a large-scale online data collection, 18,123 experimental participants were randomly allocated to 45 randomly selected experimental designs out of 95 submitted designs. We find a small adverse effect of competition on moral behavior in a meta-analysis of the pooled data. The crowd-sourced design of our study allows for a clean identification and estimation of the variation in effect sizes above and beyond what could be expected due to sampling variance. We find substantial design heterogeneity—estimated to be about 1.6 times as large as the average standard error of effect size estimates of the 45 research designs—indicating that the informativeness and generalizability of results based on a single experimental design are limited. Drawing strong conclusions about the underlying hypotheses in the presence of substantive design heterogeneity requires moving toward much larger data collections on various experimental designs testing the same hypothesis

Financial forecasts during the crisis: Were experts more accurate than laypeople?

The main goal of this paper was to examine the accuracy and confidence of financial forecasts during the 2009/2010 crisis. The study was carried out in February 2009 in Poland. The participants represented two groups: financial analysts and laypeople (people without knowledge or skills in finance). All participants were asked to forecast future stock market performance and foreign exchange rates. Additionally, they marked their confidence on a 100-point scale. The results showed that the forecasts significantly differed from the real values. In forecasting both the stock market and the currency exchange market, the prediction error significantly differed from zero. Even if the participants were optimistic in making the directional stock market forecasts, they were pessimistic when making point index predictions, which suggests a judgmental paradox. The experts were slightly better than the non-experts in predicting the stock market. However, their accuracy was generally not better in the exchange market forecasts. The next step of the analysis focused on the confidence factor. The results of this part of the research showed that the laypeople were less confident than the experts in all the judgments.Financial forecasts Financial crisis Overconfidence Financial analysts Behavioral finance

Gender differences in allocation choices made by children aged 5 to 6

The main aim of this article is to supplement gaps in current knowledge concerning the development of competences related to goods allocation choices. We conducted a study in which 158 children aged 5 to 6 made choices concerning allocations of goods between themselves and the other, anonymous child. The crucial findings point to boys as more selfish in their choices than girls. Furthermore, we provide evidence for the claim that young children (especially boys) are aware that their choices are egoistic. Since our study adopted a similar methodology to that of the recent Swiss study, we were able to conduct cross-cultural analysis. The comparison of children’s choices in the Polish study and the Swiss one pictures Polish children as displaying a stronger egalitarian preferences and revealing egoistic preferences less frequently than the children from Switzerland
