Contrast Effects in Judgments of Health Hazards

Abstract

Researchers commonly use 2 models to explain contrast effects (CEs): the standard-of-comparison model and the set-reset model. The 2 models focus on the role of categorization to predict when a CE (instead of an assimilation effect) will happen, while minimizing the role of knowledge accessibility and relevance in determining whether any effect will occur. A 3rd model, the selective-accessibility model (F. Strack & T. Mussweiler, 1997), focuses on knowledge accessibility and relevance, but it is a model of assimilation effects in the anchoring bias. In the present study of CEs, the authors tested 3 predictions implied by the selective-accessibility model. The authors found a CE only when anchor- and target-rating dimensions matched and only in the 1 st of multiple targets rated. The CE required a minimum amount of attention to the anchor. These results support the account that selective knowledge accessibility and relevance play an important role in CEs.     

The emergence and implementation of health goals

Abstract

Modern theorizing on goals is applied to an analysis of the implementation and the emergence of health goals. First, a model of action phases and its concomitant concepts of implemental mindsets and implementation intentions (Gollwitzer, 1990, 1993) are used to explore how the initiation of health goal directed behaviors can be facilitated and how the performance of health goal directed actions is enhanced. Second, recent theorizing on the psychology of thinking about the future (Oettingen, 1996; 1997) is employed to discuss conditions and processes of the emergence of health goals. It is suggested that contrasting positive fantasies about the future with reflections on the negative aspects of reality create binding health goals that reliably affect people's behaviors.     

Category-bounded emotional enhancement: spillover effects in the valuation of public goods

ABSTRACT

We examined whether enhancing (vs. not enhancing) the emotionality of a referent public good influences the subsequent valuation of a target public good. We predicted that it would and that the directionality of its impact would depend on a fundamental cognitive process – categorisation. If the target and referent goods belong to the same domain, we expected that the effect on the target would be in the same direction as the emotional enhancement of the referent (assimilation effect). However, if the target and referent goods belong to different domains, we expected that the effect on the target would be either negligible or in the opposite direction to that of the emotional enhancement of the referent (null or contrast effect). In Experiment 1 we examined the impact of emotionally enhancing a referent public good on feelings towards a target public good, whereas in Experiment 2 on the willingness to contribute towards a target public good. The results support the predicted interaction, which was driven by an assimilation effect for same-domain goods and a null effect for different-domain goods. In doing so, the present findings highlight the interplay between cognition and emotion in the valuation of public goods. We discuss theoretical and practical implications.     

The Relationship of Temperament Scores to the Way Young Adults Adapt to Change

Temperament has been suggested as affecting the way individuals adapt to changes. This study examined the relationship of temperament, as measured by the Dimensions of Temperament Scale (Lerner, Palermo, Spiro, & Nesselroade, 1982), to three aspects of adaptation for 167 students starting post-secondary education. Loneliness was measured using Schmidt and Sermat's (1983) Differential Loneliness Scale, involvement was measured using Scales of Satisfaction and Activity (Vinsel, Brown, Altman, & Foss, 1980), and affect was measured using the Multiple Affect Adjective Checklist (Zuckerman & Lubin, 1965a). In the sample, feelings of loneliness were related to temperament differentially with regard to friends, romantic-sexual relationships, groups, and family. Involvement was best predicted by the approach/withdrawal dimension, whereas affect was best predicted by the dimensions of mood. The results are consistent with earlier work with children and lend support to the view of temperament as an active mechanism by which the individual adapts to life changes.     

Transhumanism and Roman Catholicism: Imagined and Real Tensions

Abstract

Transhumanists have asserted that religious people would both oppose life extension and allowing people with extended lives to die. In this paper, coming from a Roman Catholic perspective, I refute four myths associated with these claims: that the Church materially opposes life extension, that it conceptually opposes the very idea of life extension, that it opposes human genetic manipulation, and that it opposes letting people die in hospitals. I then propose that there are four real tensions that are much more significant: that material immortality is highly improbable, that injustice and inequality are major concerns, that transhuman omnipotence is impossible, and that utopianism is extremely dangerous.     

Impact of Experimentally Induced Positive and Anxious Mood on Alcohol Expectancy Strength in Internally Motivated Drinkers

The effects of musically‐induced positive and anxious mood on explicit alcohol‐related cognitions (alcohol expectancy strength) in 47 undergraduate students who consume alcohol either to enhance positive mood states (for enhancement motives) or to cope with anxiety (for anxiety‐related coping motives) were investigated. Pre‐ and post‐mood induction, participants completed the emotional reward and emotional relief subscales of the Alcohol Craving Questionnaire – Now. The hypothesis that anxiety‐related coping motivated drinkers in the anxious mood condition (but not those in the positive mood condition) would exhibit increases in strength of explicit emotional relief alcohol expectancies after the mood induction was supported. An additional, unanticipated finding was that enhancement‐motivated drinkers in the anxious condition also showed significant increases in strength of explicit emotional relief (but not emotional reward) alcohol expectancies. The hypothesis that enhancement‐motivated (but not anxiety‐related coping motivated) participants would exhibit increases in explicit emotional reward expectancies following exposure to the positive mood induction procedure was not supported. Taken together with past research findings, the current results highlight the importance of distinguishing between subtypes of negative affect (i.e., anxious and depressed affect) in exploring the affective antecedents of explicit alcohol outcome expectancies.     

Supplementing Virtue: The Case for a Limited Theological Transhumanism

This paper considers the prospect of moral transhumanism from the perspective of theological virtue ethics. I argue that the pursuit of goodness inherent to moral transhumanism means that there is a compelling prima facie case for moral enhancement. However, I also show that the proposed enhancements would not by themselves allow us to achieve a life of virtue, as they appear unable to create or enhance prudence, the situational judgement essential for acting in accordance with virtue. I therefore argue that moral enhancement technologies should take a limited or supporting role in moral development, which I call “moral supplementation.”     

An Alternative Solution to Lifting the Ban on Doping: Breaking the Payoff Matrix of Professional Sport by Shifting Liability Away from Athletes

The persistence of doping in professional sports—either by individuals on an isolated basis and by whole teams as part of a systematic doping programme—means that professional sport today is rarely if ever untainted. There are financial incentives in place that incentivise doping and there are data that show that doping is often a systematic, organised enterprise (either at team-level, or at state-level). The main question to be answered today in professional sports is whether doping’s repressive anti-doping policies do not have greater negative consequences for society. Whilst some have suggested legitimising safe doping under medical control, in this paper, I argue that doing so will do little to prevent clandestine use of dangerous performance-enhancing substances, and suggest an alternative solution to lifting the ban on doping, i.e. starting from extending liability for doping in sport beyond athletes to those holding power and authority over athletes, to changing winning incentives for doping, to making sport sustainable in the longer time by devising ways of providing athletes with a steady income which is not linked to record breaking or sponsorships.     

亮度对空间-数字反应编码联合效应的影响

本研究探讨亮度对空间-数字反应编码联合效应（Spatial-Numerical Association of Response Codes,简称SNARC效应）的影响及其机制。通过三个实验设计不同的亮度对比水平,要求被试对阿拉伯数字1~9（5除外）进行奇偶判断。实验一将数字亮度设为最高值255时,结果出现了数字的SNARC效应。实验二将数字的亮度值分别设为255和213时,结果仍存在SNARC效应。实验三将亮度值分别设置为213和42时,数字的SNARC效应却消失了。这些结果表明亮度会激活或抑制数字的空间表征,可能与亮度对比值的高低及所消耗认知资源的多少有关。     

The dynamics of successive induction in larval zebrafish

Charles Sherrington identified the properties of the synapse by purely behavioral means—the study of reflexes—more than 100 years ago. They were subsequently confirmed neurophysiologically. Studying reflex interaction, he also showed that activating one reflex often facilitates another, antagonistic one: successive induction, which has since been demonstrated in a wide range of species, from aphids to locusts to dogs and humans. We show a particularly orderly example in zebrafish (Danio rerio) larvae; the behavior (locomotion) of larvae is low in dark and intermediate in light, but low in light and substantially higher in dark when dark followed light. A quantitative model of a simple dynamic process is described that readily captures the behavior pattern and the effects of a number of manipulations of lighting conditions.
