Evidence for Opportunity Cost Neglect in the Poor

People often neglect opportunity costs: They do not fully take into account forgone alternatives outside of a particular choice set. Several scholars have suggested that poor people should be more likely to spontaneously consider opportunity costs, because budget constraints should lead to an increased focus on trade‐offs. We did not find support for this hypothesis in five high‐powered experiments (total N = 2325). The experiments used different products (both material and experiential) with both high and low prices (from $8.50 to $249.99) and different methods of reminding participants of opportunity costs. High‐income and low‐income participants showed an equally strong decrease in willingness to buy when reminded of opportunity costs, implying that both the rich and the poor neglect opportunity costs. © 2017 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.     

Stereotype Threat Effects on Learning From a Cognitively Demanding Mathematics Lesson

Stereotype threat—a situational context in which individuals are concerned about confirming a negative stereotype—is often shown to impact test performance, with one hypothesized mechanism being that cognitive resources are temporarily co‐opted by intrusive thoughts and worries, leading individuals to underperform despite high content knowledge and ability (see Schmader & Beilock, 2012 ). We test here whether stereotype threat may also impact initial student learning and knowledge formation when experienced prior to instruction. Predominantly African American fifth‐grade students provided either their race or the date before a videotaped, conceptually demanding mathematics lesson. Students who gave their race retained less learning over time, enjoyed the lesson less, reported a diminished desire to learn more, and were less likely to choose to engage in an optional math activity. The detrimental impact was greatest among students with high baseline cognitive resources. While stereotype threat has been well documented to harm test performance, the finding that effects extend to initial learning suggests that stereotype threat's contribution to achievement gaps may be greatly underestimated.     

内隐人格观对他人知觉的影响

以大学生为被试,采用投射测验法分离出两类不同性质的内隐人格观,然后通过效价匹配实验和错觉关联实验,初步探讨了内隐人格观对他人知觉的信息加工模式的影响。研究结果表明:(1)跨性格、能力等不同人格属性有共通一致的内隐观;(2)固存观的反面就是渐变观,它们是同一维度的两极;(3)与渐变观者相比,固存观者更易以一种评价性方式知觉他人信息;同时,渐变观者不像固存观者那样对他人特质作出静态判断,而是集中注意力于理解他人行为发生的动态过程。     

负性情绪词语在外显和内隐记忆测验中的定向遗忘效应

以两类具有不同负性情绪强度值的高频汉语双字词为材料,采用项目法定向遗忘范式,探究负性情绪词语在外显和内隐记忆测验中是否存在定向遗忘效应。结果显示,(1)在外显记忆测验中,强、弱负性词均出现了显著的定向遗忘并且弱负性词的定向遗忘效应大于强负性词;(2)在内隐记忆测验中,只有弱负性词出现了显著的定向遗忘,而强负性词则无。可见,内隐记忆测验中的定向遗忘效应对负性信息比外显记忆测验更加敏感。     

Effectiveness of a Classroom Mindfulness Coloring Activity for Test Anxiety in Children

To evaluate the effectiveness of mindfulness-based structured versus unstructured coloring on test anxiety, 52 participants (53.8% female; M_age = 10.92 years, SD =.82) were randomly assigned to either a structured mandala (n = 26) or free coloring condition (n = 26), and completed a standardized anxiety measure to assess anxiety before and after coloring, immediately before a spelling test. Results revealed an overall decrease in anxiety for both groups. However, a significant gender by group interaction demonstrated that while both genders experienced anxiety reduction in the mandala condition, males reported a greater anxiety reduction in the free coloring condition while females only benefited from the mandala condition. Possible explanations for these gender effects are explored and future directions discussed.     

Observer judgmental accuracy of personality: Benefits related to being a good (normative) judge

The current study tested the hypothesis that accuracy of personality judgment would be positively related to beneficial life outcomes. 189 participants observed targets across 5 dyadic interactions and made judgments of the 10 targets on the Big Five traits. Self and acquaintance ratings were used as the accuracy criteria. Normative accuracy for all traits was related to agreeableness, and normative accuracy for some traits was positively related to interpersonal control, interpersonal support, positive affect, and life satisfaction. Distinctive accuracy was not related to beneficial outcomes. These results imply that normative accuracy based on observation is associated with beneficial outcomes, whereas distinctive accuracy is not.     

MLK Day and Racial Attitudes: Liking the Group More but Its Members Less

Intuition suggests that the Martin Luther King holiday (MLK Day) should improve racial attitudes toward African Americans. However, its influence may depend on whether African Americans are evaluated as a group or individually. In two studies, we assessed racial attitudes either on MLK Day or on a control day. As might be expected, participants had more sympathetic attitudes towards African Americans as a group on MLK Day compared to control days; however, they evaluated individual African American exemplars more negatively on MLK Day compared to control days, who presumably seemed worse by comparison to the eminent political figure.     

Judging the Goring Ox: Retribution Directed Toward Animals

Prior research on the psychology of retribution is complicated by the difficulty of separating retributive and general deterrence motives when studying human offenders (Study 1). We isolate retribution by investigating judgments about punishing animals, which allows us to remove general deterrence from consideration. Studies 2 and 3 document a “victim identity” effect, such that the greater the perceived loss from a violent animal attack, the greater the belief that the culprit deserves to be killed. Study 3 documents a “targeted punishment” effect, such that the responsive killing of the actual “guilty” culprit is seen as more deserved than the killing of an almost identical yet “innocent” animal from the same species. Studies 4 and 5 extend both effects to participants' acceptance of inflicting pain and suffering on the offending animal at the time of its death, and show that both effects are mediated by measures of retributive sentiment, and not by consequentialist concerns.     

Non‐Bayesian Noun Generalization in 3‐ to 5‐Year‐Old Children: Probing the Role of Prior Knowledge in the Suspicious Coincidence Effect

It is unclear how children learn labels for multiple overlapping categories such as “Labrador,” “dog,” and “animal.” Xu and Tenenbaum (2007a) suggested that learners infer correct meanings with the help of Bayesian inference. They instantiated these claims in a Bayesian model, which they tested with preschoolers and adults. Here, we report data testing a developmental prediction of the Bayesian model—that more knowledge should lead to narrower category inferences when presented with multiple subordinate exemplars. Two experiments did not support this prediction. Children with more category knowledge showed broader generalization when presented with multiple subordinate exemplars, compared to less knowledgeable children and adults. This implies a U‐shaped developmental trend. The Bayesian model was not able to account for these data, even with inputs that reflected the similarity judgments of children. We discuss implications for the Bayesian model, including a combined Bayesian/morphological knowledge account that could explain the demonstrated U‐shaped trend.
