Self‐framing of risky choice

Previous research on framing effects has largely focused on how choice information framed by external sources influences the response of a decision maker. This research examined how decision makers framed choice options and how the hedonic tone of self‐framing influenced their risk preference. By using pie charts and a complementary sentence‐completion task in Experiment 1, participants were able to interpret and frame the expected choice outcomes themselves before making a choice between a sure option and a gamble in either a life–death or a monetary problem. Each of these self‐frames (phrases) was then rated by a group of independent judges in terms of its hedonic tone. The hedonic tone of self‐frames was mostly positive and was more positive in the life–death than the monetary context, suggesting a motivational function of self‐framing. However, positive outcomes were still more likely to be framed positively than negative outcomes. In Experiment 2, choice outcomes were depicted with a whole‐pie chart instead of a pie slice in order to emphasize positive and negative outcomes equally. The results showed that the hedonic tone of self‐framing was still largely positive and more positive in the life domain than the monetary domain. However, compared to Experiment 1, the risk preference in the life–death domain was reversed, showing an outcome salience effect: when the pie‐slice chart emphasized only survival outcomes, participants were more risk taking under positive hedonic frames whereas when the whole‐pie chart depicted both survival and mortality outcomes, they became risk averse under positive frames. In sum, self‐framing reflected a positive bias in encoding risk information and affected the risk preference of the decision maker. Like the tone of voice used in communication, the hedonic tone of self‐framing, either positive or negative, can affect risk perception of a choice problem.

论相对于生产力的"自然破坏力"

从历史到现代,人类实践体系中总是不时地孕育出某种破坏性力量(本文称之为“自然破坏力”),这种破坏力与一直被视为实践积极成果的物质生产力密切相关,共同影响社会发展。以前我们仅仅正面地看待实践,遗忘了孕育出“自然破坏力”的实践的负面性。其实,引入“生产力”与“自然破坏力”的对立,才能使生产力和生产关系的理论对于现代发展更富有解释力。     

Trichotomous preferences for gambles

Let G_X be the set of all gambles on a set X of decision outcomes. Trichotomous preferences divide G_X into three disjoint subsets, viz., the set P⁺ of preferable gambles, the set P⁰ of indifferent gambles, and the set P^- of unpreferable gambles. Those preference comparisons are made against the status quo, i.e., the do-nothing alternative. This paper presents and discusses dyadic representations of such trichotomous preferences and identifies necessary and sufficient axioms for the existence of those representations.

Adolescent Fathers Who Are Incarcerated Juvenile Offenders: Explanatory Study of the Co-Occurrence of Two Problem Behaviors

We identify explanatory risk variables associated with the co-occurrence of two problem behaviors: juvenile offending and adolescent fatherhood. Data were gathered from a 5-year prospective, longitudinal study of 531 incarcerated juvenile offenders as they transitioned from youth correction facilities back into the community. Of the total sample, 125 (28.3%) of the male participants reported fatherhood before their 20th birthday. Six risk variables were predictive of adolescent fatherhood in this sample: (a) gang member, (b) resided with non-biological parent as primary caretaker, (c) low SES, (d) child of parent with alcoholism, (e) low mother education, and (f) family member convicted of a felony. These variables were then placed in individual, family, and social domains. Cumulative probabilities identified family related variables as the primary domain contributing to the predictive multivariate model. These results provide support for the development of prevention and interventions strategies focused across multiple ecological contexts, focusing specifically on the family unit.     

Impulsivity as a predictor of smoking and alcohol consumption

This prospective study examined the relationships between impulsivity, smoking and alcohol use in a large non-clinical sample of 601 men and 4832 women working in 12 Finnish hospitals. Data on impulsivity, smoking and alcohol consumption were collected by two questionnaires with a two-year interval. At baseline, impulsivity was associated with smoking and alcohol use. After controlling for baseline smoking, impulsivity predicted increased number of cigarettes smoked per day in women (p=0.08), but not in men. After controlling for alcohol use at baseline, impulsivity predicted increased alcohol consumption similarly in both genders (p<0.01). Higher impulsivity was also associated with increased likelihood of taking up smoking or becoming a heavy drinker (p<0.05). This evidence suggests that impulsivity contributes to increasing health risk behaviours.     

What Voters Do: Information Search During Election Campaigns

Learning about political candidates before voting can be a cognitively taxing task, given that the information environment of a campaign may be chaotic and complicated. In response, voters may adopt decision strategies that guide their processing of campaign information. This paper reports results from a series of process-tracing experiments designed to learn how voters in a presidential primary election adopt and use such strategies. Different voters adopt different strategies, with the choice of strategy dependent on the campaign environment and individual voter characteristics. The adoption of particular strategies can have implications for how voters evaluate candidates.     

Caring for Nature: From Fact to Value, from Respect to Reverence

Abstract. Despite the classical prohibition of moving from fact to value, encounter with the biodiversity and plenitude of being in evolutionary natural history moves us to respect life, even to reverence it. Darwinian accounts are value‐laden and necessary for understanding life at the same time that Darwinian theory fails to provide sufficient cause for the historically developing diversity and increasing complexity on Earth. Earth is a providing ground; matter and energy on Earth support life, but distinctive to life is information coded in the genetic molecules that superintends this matter‐energy. Life is generated and regenerated in struggle, persists in its perishing. Such life is also a gift; nature is grace. Biologists and theologians join in celebrating and conserving the genesis on Earth, awed in their encounter with this creativity that characterizes our home planet.     

Exploring the rabbit hole of possibilities by myself or with my group: The benefits and liabilities of activating counterfactual mind‐sets for information sharing and group coordination

The current experiment explored the effect of activating a counterfactual mind‐set on the discussion of unique information and group judgment accuracy. Evidence suggests that a counterfactual mind‐set is characterized by a focused, analytic mental state and, when activated at the group level, improves group judgment accuracy in the murder mystery paradigm (a hidden profile task). We hypothesized that the beneficial effect of the counterfactual mind‐set would only help group problem‐solving tasks if the mind‐set had been activated at the group level, allowing the analytical mind‐set to play out in an atmosphere of synergistic coordination. In contrast, if this highly focused mental state is activated at the individual level, it could impair group judgment quality because inwardly focused analytical individuals may fail to coordinate their behavior with other group members. Consistent with our hypothesis, activating a counterfactual mind‐set at the individual level had a debilitating effect on the group judgment task, whereas activating a counterfactual mind‐set at the group level had a facilitative effect, increasing information sharing, synergistic coordination and judgment accuracy.
