越近越诱惑？感知食物空间距离对消费欲望的影响

探讨消费欲望的影响因素及影响机制对解决个体非健康饮食问题具有重要意义。采用2个实验考察感知食物空间距离是否及如何影响消费欲望,以及感知资源口腔占用是否会降低感知空间距离对消费欲望的影响。结果发现：（1）感知空间距离越近,消费欲望越强;（2）感知空间距离通过心理模拟影响消费欲望;（3）占用感知资源口腔会阻碍心理模拟从而降低感知食物空间距离对消费欲望的影响。因此,操纵食物的感知空间距离会通过心理模拟影响个体的消费欲望。     

低阶层大学生的炫耀性消费:自尊补偿与地位追求

近年来低阶层大学生炫耀性消费负性事件频发,研究以补偿性消费理论为基础,考察低阶层大学生炫耀性消费的内因与外因。实验一通过比较高、低状态自尊条件下不同阶层被试的炫耀性消费倾向来考察自尊的作用,结果表明低阶层大学生的炫耀性消费倾向受到其状态自尊的调节; 实验二通过比较不同阶层被试对地位及非地位符号商品的支付意愿来考察商品符号价值的作用,结果表明低阶层大学生只有在商品具有地位符号价值时,才会表现出比高阶层大学生更强烈的炫耀性消费倾向。     

Facilitating Adolescent Well‐Being: A Review of the Challenges and Opportunities and the Beneficial Roles of Parents,Schools, Neighborhoods,and Policymakers

Adolescents face exceptional challenges and opportunities that may have a lifelong impact on their consumption and personal and societal well‐being. Parents, community members (schools and neighborhoods), and policymakers play major roles in shaping adolescents and influencing their engagement in consumption behaviors that are either developmentally problematic (e.g., drug use and unhealthy eating) or developmentally constructive (e.g., academic pursuits and extracurricular activities). In this article, we discuss two main topics: (a) the challenges and opportunities that characterize adolescence, based primarily on research in epidemiology and neuroscience, and (b) the ways that parents, community members, and policymakers can facilitate positive adolescent development, based on research from many disciplines including marketing, psychology, sociology, communications, public health, and education. Our goal is to summarize the latest scientific findings that can be used by various stakeholders to help adolescents navigate this turbulent period and become well‐adjusted, thriving adults.     

元认知中自信心对联合决策的预测作用

元认知通常指个体对自身认知活动的主观判断, 自信心作为其指标之一, 对个体认识和调节自己的行为有重要作用。研究表明自信心指标在联合研究过程中常见的任务类型涉及基础和高级心理加工过程, 此外, 自信心对联合决策的预测逐渐向基于计算模型的探索性参数变化。最后, 自信心的神经生理研究发现了前额叶皮层及其相关脑区和后顶叶皮层的重要性。今后应注重探索可能的预测参数和模型, 优化自信心对联合决策的预测作用。

Personality traits and alcohol consumption in a sample of non-alcoholic women

Many studies have shown the importance of personality traits as factors related to alcohol use and misuse. The relationship between personality traits and alcohol consumption was studied in a sample of 149 non-alcoholic women using the Karolinska Scales of Personality (KSP) and the Eysenck Personality Questionnaire-Revised (EPQ-R). The results showed positive correlations between alcohol consumption and disinhibitory personality traits (sensation seeking, impulsivity, psychopathy, nonconformity) and dimensions (psychoticism and extraversion). Sensation seeking combined with impulsivity were the strongest predictors of alcohol consumption. Anxiety-related traits and neuroticism were not related to alcohol frequency/amount of alcohol use.     

Acquisition of social referencing via discrimination training in infants

This experiment investigated social referencing as a form of discriminative learning in which maternal facial expressions signaled the consequences of the infant's behavior in an ambiguous context. Eleven 4- and 5-month-old infants and their mothers participated in a discrimination-training procedure using an ABAB design. Different consequences followed infants' reaching toward an unfamiliar object depending on the particular maternal facial expression. During the training phases, a joyful facial expression signaled positive reinforcement for the infant reaching for an ambiguous object, whereas a fearful expression signaled aversive stimulation for the same response. Baseline and extinction conditions were implemented as controls. Mothers' expressions acquired control over infants' approach behavior for all participants. All participants ceased to show discriminated responding during the extinction phase. The results suggest that 4- and 5-month-old infants can learn social referencing via discrimination training.     

The effect of food toppings on calorie estimation and consumption

In this research we examine the effect of adding a food topping to the base food on consumers' calorie estimation and consumption of the augmented food (base food plus topping). We show that consumers underestimate the calorie content of augmented food with an unhealthy base, especially when the topping is healthy. However, consumers are less likely to underestimate the calorie content of augmented food with a healthy base, regardless of whether the topping is healthy or unhealthy. Further, we show that adding a healthy topping to an unhealthy base makes consumers not only underestimate the calorie content but also eat more of the augmented food.     

The flip side of vanity sizing: How consumers respond to and compensate for larger than expected clothing sizes

Vanity sizing has become a popular retail trend and recent work shows it has a favorable impact on consumers. However, as the current research demonstrates, significant variations in sizing standards across retailers mean that consumers are as likely to encounter larger sizes as they are smaller, “vanity” sizes when shopping, highlighting the importance of understanding how consumers react to this potential threat in the marketplace. Across five studies we demonstrate that larger sizes result in negative evaluations of clothing and show that these effects are driven by consumers' appearance self-esteem. Importantly, we also find that instead of unilaterally lowering purchase intent as one might assume, larger sizes can actually increase spending, as consumers engage in compensatory consumption to help repair their damaged self-esteem. In so doing, this research reveals a dynamic and complex relationship between consumers and sizing labels, where shopping can serve to build, strengthen, threaten, and/or repair appearance self-esteem.
