On the origin of worries about modern health hazards: Experimental evidence for a conjoint influence of media reports and personality traits

Objective: Worries about health threatening effects of potential health hazards of modern life (e.g. electric devices and pollution) represent a growing phenomenon in Western countries. Yet, little is known about the causes of this growing special case of affective risk perceptions termed Modern Health Worries (MHW). The purpose of this study is to examine a possible role of biased media reports in the formation of MHW.

Design: In two experiments, we investigated whether typical television reports affect MHW. In Study 1, 130 participants were randomly assigned to a film on idiopathic environmental intolerance (IEI) or a control film about cystic fibrosis. In Study 2, 82 participants were randomly assigned to either a film on the dangers of electromagnetic fields or a control condition.

Main outcome measures: Increases in MHW after sensational media reports.

Results: In Study 1, only participants high on the personality trait of absorption revealed increased MHW after watching the IEI film. In Study 2, specifically worries about radiation were found to be elevated after watching the film on the dangers of electromagnetic fields compared to the control film.

Conclusion: The results of both studies reveal a significant and specific influence of sensational short mass media reports on MHW. The influence of potential moderators such as absorption remains to be clarified.     

Integration processes during frequency graph comprehension: Performance and eye movements while processing tree maps versus pie charts

Frequency graph types differ in the way how data are translated into visual representations. We compared 2 visualization methods, a traditional circular representation (pie chart) and a rectangular representation (constant column width tree map), which were hypothesized to differ regarding the cognitive ease of visual comparison processes. Performance was evaluated in tasks involving proportion and comparison judgments under both highly controlled and more realistic circumstances. The results showed performance benefits (in terms of reduced response times or error rates) for rectangular representations. Additional eye movement analyses revealed that this benefit was mainly due to a facilitation of scanning the graph for relevant information. The results suggest that facilitating comparison processes by representing the critical variable in less complex visual dimensions (i.e., straight length with constant orientation instead of surface area or curved length) eventually enhances the efficiency of integration processes during graph comprehension.     

Two types of debunking arguments

Debunking arguments are arguments that seek to undermine a belief or doctrine by exposing its causal origins. Two prominent proponents of such arguments are the utilitarians Joshua Greene and Peter Singer. They draw on evidence from moral psychology, neuroscience, and evolutionary theory in an effort to show that there is something wrong with how deontological judgments are typically formed and with where our deontological intuitions come from. They offer debunking explanations of our emotion-driven deontological intuitions and dismiss complex deontological theories as products of confabulatory post hoc rationalization. Through my discussion of Greene and Singer’s empirically informed debunking of deontology, I introduce the distinction between two different types of debunking arguments. The first type of debunking argument operates through regular undercutting defeat, whereas the second type relies on higher-order evidence. I argue that the latter type of debunking argument, of which the argument from confabulation is an example, is objectionably sloppy and therefore inadmissible in academic discussion.     

Autobiographical remembering regulates emotions: a functional perspective

Emotional deviation has been considered an essential factor in emotion regulation, in that, attempts to compensate for the deviation is reflected on cognitive processes. In the present study, we focused on autobiographical remembering and tested the functional role of memory on emotion regulation. We specifically examined the congruence effect in individuals’ subsequent memory reports after recalling emotional events. Individuals were randomly assigned to three groups to report either sadness or anger evoking events or emotionally unspecified events that they experienced in the last five years. Results supported mood-incongruence, but only for the emotional memory groups. Despite highly negative memories reported in the initial recall, individuals in anger- and sad-memory groups revealed an up-regulation trend in subsequent recall. Furthermore, sadness and anger induction affected phenomenological features of the subsequently reported memory. Overall, our findings supported for the emotion regulation function of remembering that serves counter-regulation of the negative emotion. We discuss potential mechanisms in the light of explanations by a functional approach to autobiographical memory.     

Naïve and Robust: Class‐Conditional Independence in Human Classification Learning

Humans excel in categorization. Yet from a computational standpoint, learning a novel probabilistic classification task involves severe computational challenges. The present paper investigates one way to address these challenges: assuming class‐conditional independence of features. This feature independence assumption simplifies the inference problem, allows for informed inferences about novel feature combinations, and performs robustly across different statistical environments. We designed a new Bayesian classification learning model (the dependence‐independence structure and category learning model, DISC‐LM) that incorporates varying degrees of prior belief in class‐conditional independence, learns whether or not independence holds, and adapts its behavior accordingly. Theoretical results from two simulation studies demonstrate that classification behavior can appear to start simple, yet adapt effectively to unexpected task structures. Two experiments—designed using optimal experimental design principles—were conducted with human learners. Classification decisions of the majority of participants were best accounted for by a version of the model with very high initial prior belief in class‐conditional independence, before adapting to the true environmental structure. Class‐conditional independence may be a strong and useful default assumption in category learning tasks.     

Generalized Information Theory Meets Human Cognition: Introducing a Unified Framework to Model Uncertainty and Information Search

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the world. In cognitive science, psychology, and medical decision making, Shannon entropy is the most prominent and most widely used model to formalize probabilistic uncertainty and the reduction thereof. However, a variety of alternative entropy metrics (Hartley, Quadratic, Tsallis, Rényi, and more) are popular in the social and the natural sciences, computer science, and philosophy of science. Particular entropy measures have been predominant in particular research areas, and it is often an open issue whether these divergences emerge from different theoretical and practical goals or are merely due to historical accident. Cutting across disciplinary boundaries, we show that several entropy and entropy reduction measures arise as special cases in a unified formalism, the Sharma–Mittal framework. Using mathematical results, computer simulations, and analyses of published behavioral data, we discuss four key questions: How do various entropy models relate to each other? What insights can be obtained by considering diverse entropy models within a unified framework? What is the psychological plausibility of different entropy models? What new questions and insights for research on human information acquisition follow? Our work provides several new pathways for theoretical and empirical research, reconciling apparently conflicting approaches and empirical findings within a comprehensive and unified information‐theoretic formalism.     

Stability and Change in Domain‐specific Self‐esteem and Global Self‐esteem

A notable uptick of interest in the stability of self‐esteem has been observed over the past few years. Most researchers, however, have focused on unidimensional rather than multidimensional conceptualizations of self‐esteem. The paucity of empirical research is surprising given conflicting theoretical perspectives on the stability of self‐esteem. The goal of the present study was to thoroughly disentangle different conceptualizations of self‐esteem and test opposing classical theories on (i) the stability and (ii) the direction of mutual influence of these different forms of self‐esteem. We analysed two‐year longitudinal data from participants (N = 644 at T1, N = 241 at T2) with an average age of 47.0 years (SD = 12.4). Analyses using a latent variable approach revealed that the domains of self‐esteem were relatively stable in terms of rank order and mean levels. In fact, the size of the stability coefficients was comparable to that of other trait measures that have been reported in the literature and paralleled the stability observed for global self‐esteem. Results did not provide support for either top‐down or bottom‐up effects between domain‐specific and global self‐esteem. These findings have important theoretical and practical implications regarding the stability and development of self‐esteem in adulthood and advance the understanding of self‐esteem in personality theory. © 2018 European Association of Personality Psychology     

Uppsala 1968 – The Swedish Context

The 4th Assembly of the World Council of Churches (WCC) in Uppsala, Sweden, in 1968 was an event of global significance, drawing participants from around the world under the theme “Behold, I make all things new.” At the same time, it was an event taking place in Sweden – a country that by the 1960s had become a model of “responsible society,” with strong economic growth, an all‐encompassing welfare state, and an ambitious policy for international development that was channelling material aid to Southern Africa. For the Church of Sweden, the assembly marked a continuity with the 1925 World Conference on Life and Work convened in Stockholm by Swedish Archbishop Nathan Söderblom. In turn, the Swedish churches themselves were influenced by the Uppsala assembly, especially in the renewal of liturgy and worship. This article explores the Swedish dimension of the Uppsala assembly through examining the legacy of the Stockholm conference of 1925, the societal and political context in Sweden of the 1960s, the participation of youth, and the impact of the assembly on Swedish church life.
