Less is better: when low-value options are valued more highly than high-value options

This research demonstrates a less-is-better effect in three contexts: (1) a person giving a $45 scarf as a gift was perceived to be more generous than one giving a $55 coat; (2) an overfilled ice cream serving with 7 oz of ice cream was valued more than an underfilled serving with 8 oz of ice cream; (3) a dinnerware set with 24 intact pieces was judged more favourably than one with 31 intact pieces (including the same 24) plus a few broken ones. This less-is-better effect occurred only when the options were evaluated separately, and reversed itself when the options were juxtaposed. These results are explained in terms of the evaluability hypothesis, which states that separate evaluations of objects are often influenced by attributes which are easy to evaluate rather than by those which are important. © 1998 John Wiley & Sons, Ltd.     

Effect of Force Sense to Active Joint Position Sense and Relationships between Active Joint Position Sense,Force Sense,Jumping and Muscle Strength

Abstract

We aimed to investigate the effect of external load on the joint position sense (JPS) accuracy and its relation to the target jump height. The present study also aimed to explore the relationship between force sense (FS) and maximum voluntary isometric contraction (MVIC). Participants’ MVIC levels were determined during the 45-degree knee extension task. Then, participants were asked to execute a knee JPS task with external load (EL-JPS) and with no-load (EL-JPS). To assess jumping accuracy participants were instructed to jump with their 50% of maximum jump height. Results indicated that EL-JPS error values were lower than NL-JPS. EL-JPS was correlated to jumping errors. However, the relationship between NL-JPS and jumping errors was not significant. A significant correlation was found between MVIC and FS errors.     

“别人家的孩子”vs.平庸的自己：社会比较对独特性寻求行为的影响

人们在自我评价中普遍存在着优于平均值效应, 而上行社会比较会打破这一自我评价偏差, 引发后续的补偿性消费行为。通过5个实验, 依次论证上行比较(vs.下行比较)会提升个体对独特产品选项的偏好(实验1); 其心理机制在于上行比较降低了而非下行比较提升了个体的自我独特性感知, 从而促使个体出于补偿的目的而寻求独特性(实验2a、2b和2c); 上述效应适用于经济状况这一特定比较维度, 并且在感知经济流动性的调节作用下得到强化或削弱(实验3)。研究结论对于推动社会比较和独特性寻求行为相关领域的理论进展, 指导长尾市场中企业的营销策略、帮助个体缓解上行比较的威胁均有着积极的启示价值。     

产品销量和推荐数对网络消费决策的影响:价格的调节效应

基于目标感染理论,探究了产品销量和产品推荐数对大学生网络消费决策的影响,并进一步探究了产品价格在大学生网络消费决策中的调节作用。两项研究均表明,产品销量和推荐数均会促进大学生做出消费决策。其中,产品价格调节了两者对网络消费决策的影响,具体表现为在选购低价格产品时,大学生更加看重产品销量,倾向选购高销量产品;而在选购中高价格产品时,大学生更加看重产品推荐数,选购高推荐数的产品。本研究为网络电商平台如何针对不同价位产品制定产品展示方案提供了理论支持和实践指导。     

读心的比较研究：非人灵长类与人类在心理理论上的异同点及其解释

利用非人灵长类开展比较研究是探索心理理论本质、起源和进化动因的重要途经。大量实证研究显示非人灵长类可以表现出一些基础心理理论成分,包括联合注意、意图理解和一级观点采择,这表明心理理论在灵长类动物的进化谱系中具有进化连续性。然而,非人灵长类无法像人类一样达成二级观点采择和错误信念理解,潜心智化假说、替代表征假说、最小限度心理理论假说和意识关系假说试图对此差异进行解释。尽管视角与具体内容不同,但这些假说都强调,非人灵长类无法对其他个体关于外部世界的心理信念形成表征,信念表征是非人灵长类与人类读心能力的重要分界点。未来研究需要重点澄清共享意图、语言机制以及社会生态环境因素与心理理论产生的相互影响作用。     

浅析消费领域中的审美现象

随着经济文化的发展和生活水平的提高,消费领域中出现了很多与审美相关的消费。本文透过这些现象分析消费者进行审美消费的内在动因,并且探讨一些应对思路。     

Beyond Consumptive Solidarity: An Aesthetic Response to Human Trafficking

A disturbing economic reality confronts consumers today: thousands of farm workers are enslaved in U.S. agricultural fields, forced to work without pay amid deplorable conditions and under the constant threat of violence. If structural economic injustices perpetuate modern‐day agricultural slavery, then it is necessary to promote consumer practices that resist these abusive dynamics. But a consumption‐oriented strategy does not necessarily restore either personal agency or communal relations damaged by agricultural trafficking. This essay proposes a framework for aesthetic solidarity that cultivates affective bonds necessary for building communities of resistance characterized by mutuality, equality, and participation.     

Alcohol‐aggression expectancies and dispositional aggression moderate the relationship between alcohol consumption and alcohol‐related violence

Alcohol consumption increases aggression, but only in some drinkers. This study examines how expectancies for alcohol‐induced aggression and dispositional aggression moderate the link between alcohol consumption and alcohol‐related violence, building on previous studies that have employed limited measures of alcohol‐related violence and included few women. A sample of 212 men and women reported their alcohol consumption, alcohol‐aggression expectancies, dispositional aggression, and incidents of alcohol‐related aggressive acts. Alcohol‐aggression expectancies and quantity of alcohol consumed interacted to predict alcohol‐related aggression. Alcohol‐aggression expectancies covaried with alcohol‐related aggressive acts, particularly in heavier drinkers. Dispositional aggression also correlated with alcohol‐related aggression among heavier drinkers. These results help identify that alcohol might increase aggression only among heavy drinkers who expect alcohol to increase aggression or who are dispositionally aggressive. Aggr.

Does why we reminisce reflect how you behave? Linking maternal reminiscing goals to child behavioural and emotional problems

Recent theoretical and empirical work suggests that joint mother–child reminiscence may reflect both explicit and implicit socialization goals. The present study investigates mothers' explicit socialization goals that may be enacted during joint reminiscence in relation to children's behavioural and emotional problems. Two hundred and sixty‐five mothers of 3‐ to 8‐year‐old children completed an online survey that included a measure of seven reminiscing goals (emotional understanding, behaviour control, bonding, interdependence, entertainment, memory skill development, and maintaining peer relationships). In addition, mothers completed measures of children's emotion problems, conduct problems, hyperactivity, and peer problems as well as supportive parenting and maternal attachment. Findings indicated that controlling for supportive parenting and maternal attachment, emotional understanding was a unique predictor of children's emotion problems, directing behaviour was a unique predictor of conduct problems, and bonding was a unique predictor of hyperactivity. These findings provide support for the functional nature of joint reminiscence. Copyright © 2009 John Wiley & Sons, Ltd.     

Emergent completion of multistep instructions via joint control

Teaching procedures that facilitate the emergence of novel responses allow for increased efficiency, which is critical when providing early-intervention services to children with autism spectrum disorder (ASD). Three 5- and 6-year-old children diagnosed with ASD participated. In Experiment 1, we demonstrated functional control over the effects of teaching echoic rehearsals on the emergence of completing novel two-step instructions via joint control and obtained generalization and maintenance of the effects in an applied, nontraining context. In Experiment 2, we conducted an experimental analysis of joint control by disrupting rehearsal of the instruction and tacts of the objects in the instruction, which served as the sources of joint control. Our results support the efficacy of the procedures for establishing first-trial performance with novel instructions and indicate that joint control is responsible for the emergent performance produced by our teaching procedures.
