The Effect of Emotion on Visual Attention to Information and Decision Making in the Context of Informed Consent Process for Clinical Trials

The aim of this study was to examine the influence of emotion on visual information processing and decision making in the context of informed consent. Researchers are ethically obligated to ensure informed consent in clinical trials; however, many volunteers have unrealistic expectations about the value of an experimental therapy. Moreover, suboptimal participation rates for clinical trials may be partially attributable to perceptions that ethical obligations to volunteers are not met. This study examines whether discrete negative emotions (fear, anger, and sadness) differentially influence information processing, visual attention, and decisions in the context of clinical trial informed consent. Community participants completed a standard emotion induction (or control) and then read an actual consent form from a clinical trial while eye movements were tracked. Fear and anger produced the most prominently different patterns of systematic processing and visual attention, such that fear induced longer fixations to information presented, whereas anger induced shorter fixations. Moreover, among women only, fear increased decisions to participate, compared with anger and neutral emotion. Examinations of associations between eye‐tracking variables and self‐reported outcomes indicated that for angry participants only, less systematic processing was associated with greater decisions to participate. Negative emotions of any kind decreased accurate perceptions of trial benefit. These patterns suggest a complex interplay among emotion, processing style, and decision making. Future research is necessary to further probe these effects among potential clinical trial volunteers. Published 2016.

Understanding Women's Experiences of Defending Against Eating Disorder Symptoms: An Interpretive Phenomenological Analysis

Body dissatisfaction predicts eating disorder symptomatology for some women but not for others. To better understand this disparity, the authors interviewed 7 college women who reported body dissatisfaction and no engagement in eating disorder symptoms. The authors identified 4 factors that may protect body‐dissatisfied women from engaging in eating disorder symptoms.     

Characterising the Personality of the Public Safety Offender and Non‐offender using Decision Trees: The Case of Colombia

The aim of this paper was to create a decision tree (DT) to identify personality profiles of offenders against public safety. A technique meeting this requirement was proposed that uses the C4.5 algorithm to derive decision rules for personality profiling of public safety offenders. The Mini‐Mult test was used to measure the personality profiles of 238 individuals. With the test results as our database, a C4.5 DT was applied to construct rules that classify each profile into one of two groups, those without and those with records of offences against public safety. The model correctly classified 80% of the personality profiles and delivered a set of decision rules for distinguishing the profiles by group, and the principal personality profiles were interpreted. We conclude that DTs are a promising technique for analysing personality profiles by their offender or non‐offender status. Finally, we believe that the development of a classifying model using DT may have practical applications in the Colombian prison system. Copyright © 2016 John Wiley & Sons, Ltd.     

Metaphor in intergroup relations

Belonging to groups and relating to other groups are central parts of our lives, but they confront us with abstract ideas (e.g., identity and power) and nebulous feelings. To make sense of it all, people rely on conceptual metaphors: cognitive tools that ground abstractions in dissimilar, more concrete ideas that are easier to grasp. We review some common metaphors that people use in intergroup contexts—metaphors that draw on knowledge of such familiar experiences as physical cleansing and warmth sensations. We review evidence that these metaphors are not mere figures of speech, but have a systematic and practically important influence on intergroup attitudes and behavior. Most of this work shows that reliance on metaphor contributes to prejudice, stereotyping, and discrimination, sometimes without the person's awareness. Yet we consider the hopeful possibility that citizens, politicians, and researchers can harness the power of metaphor to promote intergroup harmony and peace.

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.

Theology and Interpretation: The Case of Aquinas and Calvin on Romans

This article explores how Aquinas's and Calvin's theology of justification, the law and the nature of human works integrate with their interpretations of Romans by analyzing their commentaries on 1:16b–17, focusing on the iustitia Dei, and 2:13, which addresses the relationship between works and justification. Aquinas's interpretation unfolds by emphasizing the work of Christ in and through sinners, while Calvin's interpretation emphasizes the work of Christ for and to sinners. I also demonstrate how the theological judgements embedded in these sections inform their reading of Romans as a whole.
