Social dilemmas: When self-control benefits cooperation

Individuals in a social dilemma may experience a self-control conflict between urges to act selfishly and their better judgment to cooperate. Pairing a public goods game with a subtle framing technique, we test whether perception of self-control conflict strengthens the association between self-control and cooperation. Consistent with our hypothesis, cooperative behavior is positively associated with self-control in the treatment that raised the relative likelihood of perceiving conflict, but not associated with self-control in the treatment that lowered the likelihood. These results indicate that it is important to understand the role of self-control in cooperation.     

Attention and Executive Functions as Mediators of Attachment and Behavior Problems

The purpose of this study was to provide a more comprehensive understanding of the relation between early parent‐child interactions and subsequent behavior problems and how certain cognitive processes mediate this relation. Specifically, this study investigated whether attention, inhibition, and planning skills mediate the relation between attachment security and behavior problems. Data were collected as part of the National Institute of Child Health and Development‐Study of Early Child Care and Youth Development when children (N = 1004) were between 36 months and the third grade. Results from structural equation models indicated that sustained attention mediated the relation between disorganized attachment and social problems. Planning mediated the relation between disorganized attachment and subsequent thought problems, attention problems, and delinquent behavior. Avoidant, ambivalent, and disorganized attachment directly predicted several behavior problems. Implications for theory and future research are discussed.     

茶叶供应者质量安全认知与行为分析——基于浙江500位茶叶供应者的问卷调查

茶叶质量安全问题制约了中国茶叶产业的可持续发展。通过构建茶叶供应质量控制主要环节结构体系,对各环节供应者质量安全认知与质量控制行为考察,利用TOPSIS模型对茶叶供应质量控制关键点进行分析,归纳出当下茶叶供应链质量控制关键环节、重要环节和普通环节。研究表明:茶叶种植者、加工者质量安全基本认知程度较低;供应者在产前环节、种植管理环节、加工环节、储运销售环节中的部分质量控制行为薄弱。茶叶供应者素质良莠不齐是质量安全认知层次不同的主要原因,因此,需对不同供应者有针对性地进行质量安全认知强化。     

5-6岁幼儿分享行为和分享动机研究

本研究以厦门市某幼儿园的40名5-6岁幼儿为被试，运用实验法和访谈法，探讨“偶得物品”和“拥有性物品”下幼儿分享行为及其分享动机的特点。结果如下：（1）百分之百的幼儿具有正确的分享判断，但绝大部分幼儿并不愿意分享，“偶得物品”和“拥有性物品”之间的分享行为并没有明显差异。（2）愿意分享的幼儿中，被动分享占主导，其中一大部分是伪分享行为。（3）分享动机中，“同伴倾向”占主导，尤其是“偶得物品”的分享动机；“权威/规则倾向”和“移情倾向”也占有重要地位。

Price-setting newsvendor with strategic consumers

We consider a newsvendor who sells a single product over a single season with the objective of determining both the selling price and stock quantity to maximize the expected profit. The customers are strategic and we consider two demand cases: additive and multiplicative. For each case, we derive the newsvendor׳s optimal decisions and demonstrate that neglecting the price-sensitivity of demand leads the newsvendor to make sub-optimal decisions. Moreover, we show that under certain conditions, strategic consumer behavior may positively affect the newsvendor׳s optimal expected profit in the additive demand case.     

Exploring the nonverbal facet of ethnic discrimination: a field experiment on anti-Roma racism in the Paris métro

A field experiment on the discrimination of Roma migrants from Eastern Europe was conducted in two stations of the Paris metro to explore the behaviors that may communicate misrecognition in everyday encounters. An actress asked for help to randomly chosen passengers on a metro platform, wearing a glaringly Romani skirt in the treatment condition but an unconspicuous middle-class style in the control condition. In interaction with the actress wearing the Romani skirt, passengers were found to enact the so-called “visual dominance pattern”, and male passengers in particular were found to keep greater distances. Reverse discrimination also occurred as women kept shorter distances from the actress bearing the ethnic stigma. Last, passengers helped less the stigmatized actress, but only in one of the two metro stations where trials were conducted.     

Sexual objectification decreases women’s experiential consumption (but not material consumption)

The current investigation examined our prediction that sexual objectification decreases women’s experiential consumption but not material consumption. Three experiments provided converging support for this prediction. In particular, female participants reported lower tendency to engage in experiential consumption after recalling a past experience of objectification (Studies 1 and 3) and chose a material product over an experiential one after receiving objectifying comments (Study 2). Furthermore, Study 3 found that sexual objectification reduced purchase inclination of experiential products, and this effect did not emerge for material products. These findings contribute to the literature on sexual objectification by showing the impact of sexual objectification on women’s economic decisions and behaviors.
