非熟练的韩国汉语学习者合成词加工中词优效应的特点

词优效应是语言学习中的一个普遍现象。关于英语母语者和汉语母语者的研究都发现了词优效应。本研究关注非熟练的韩国汉语学习者的中文词汇加工中的词优效应,共两个实验:实验1考察汉字的频率对非熟练的韩国汉语学习者中文词汇加工中词优效应的影响;实验2考察汉字和词之间的语义关系(词汇的结构)对非熟练的韩国汉语学习者中文词汇加工中词优效应的影响。实验1的结果发现,字频并未对非熟练的韩国汉语学习者中文词汇加工中的词优效应产生影响,非熟练的韩国汉语学习者在高频字和低频字的识别中都出现了词优效应,且词优效应的大小没有显著差异。这说明非熟练的韩国汉语学习者在高、低频字的识别中都依赖于自上而下的词汇水平的激活。实验2的结果发现,汉字和词之间的语义关系(词汇结构)影响词优效应,相对于并列结构的词汇加工,在偏正结构的词语加工中更容易出现词优效应。这个结果表明词汇的结构通过影响词水平和字水平之间的交互激活,进而影响中文词汇加工中的词优效应。     

When Sharing Is Not Caring: Does (un)Certainty About Bill Payment Method Lead Diners to Consume More and Spend More Money?

Previous work has demonstrated that unacquainted participants in an experimental, restaurant‐like setting consume more when they know in advance that the bill will be split evenly rather than paid according to individual consumption. Real life, however, often differs from these experimental settings in two important ways. First, unlike random groups of participants, diners who eat together are frequently friends or colleagues. Second, payment method (even vs. individual payment) is usually unknown (i.e. uncertain) at the time people place their orders, and is determined when the check arrives. The current research tests the ecological validity of the association between consumption amount and payment method. Study 1 was conducted in a natural setting with organic groups of diners. Some were asked to state their desired payment method before ordering (Certain condition); others did so only after asking for the check (Uncertain condition). In both conditions, even payment (as opposed to individual payment) was associated with greater consumption amount. However, overall, consumption amount was lower among diners in the Uncertain condition than among those in the Certain condition. Study 2 presents a controlled follow‐up experiment showing that eliminating diners' prior expectations regarding the payment method—by informing them that the payment method will be randomly determined after the consumption decision—eliminates the relationship between payment method and consumption amount. This study further indicates that when diners are uncertain what the payment method will be, even bill‐splitting has negative implications for their subsequent social interactions, expressed in retribution tendencies.

Causal Models Drive Preference between Drugs that Treat a Focal versus Multiple Symptoms

This research examines the effects of causal beliefs on drug preference. In three studies, 374 undergraduate participants imagined that they suffered from a focal symptom and then indicated their preference between a drug claiming to treat only the focal symptom (single treatment) and a drug claiming to treat the focal symptom and a nonfocal symptom (dual treatment) they thought resulted from a common‐cause or from a different cause. Participants who thought that the symptoms resulted from different causes significantly preferred the single treatment drug more and the dual treatment drug less than participants who thought the symptoms resulted from a common‐cause. Process analysis yielded a significant mediation effect. Specifically, an individual's causal model determines preference by affecting the estimates of the potential gain and loss associated with using each drug. Participants who held a common‐cause model concerning the source of the symptoms thought they would be more likely to need the nonfocal treatment provided by the dual treatment drug and less likely to suffer from side effects when taking this drug, than those with a different‐cause model. The results demonstrate the influence of causal structure on judgment and choice. © 2017 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.     

When Does Construction Enhance Product Value? Investigating the Combined Effects of Object Assembly and Ownership on Valuation

Recent findings have shown that even without the ability to customize a product, individuals pay more for goods that they assembled. In this paper we examine which components of this creation process account for the increase in valuation, and whether it operates equally for owners and non‐owners of the self‐assembled object. Based on the self‐extension theory of ownership, we propose a psychological mechanism by which the assembly process strengthens the self–object association. In three experiments, we find that—although witnessing the assembly process or assembling a similar product can increase participants' evaluation of, and attachment to, a product that they own—a greater and more consistent increase in valuation and attachment arises when owners assemble their product themselves. Seemingly, merely learning about the assembly process plays only a small role in enhancing value; for substantial increases in value, one must actually assemble the product oneself. Contrary to the previous findings on the effects of labour on willingness to pay, we find little effect of product assembly among non‐owners of the product. We suggest that self‐assembly encourages objects to be incorporated into the self, but that this occurs most effectively when one owns the product. Copyright © 2015 John Wiley & Sons, Ltd.     

Materialism lowers well‐being: The mediating role of the need for autonomy – correlational and experimental evidence

While there is evidence from the self‐determination perspective for the mediation of basic needs satisfaction in the materialism–well‐being link, no research to date has attempted to examine the relative contribution of the three needs to the mediating effect. Given that the predictive value of psychological needs on well‐being depends upon the match between the need and life domains, in two studies we investigate the differential mediating role of all three needs in the negative relationship between materialism and well‐being. In study 1, 231 adult participants self‐reported their materialistic attitudes, basic needs satisfaction and well‐being. In study 2 (N = 82 undergraduates), we experimentally activated materialistic thoughts and examined their effects on need satisfaction and state well‐being as compared to a neutral control condition. Study 1 furnished cross‐sectional evidence that materialism diminishes well‐being through lower satisfaction of the psychological need for autonomy only. Study 2 showed that experimental activation of materialism via short‐term exposure to pictorial consumer‐cues leads to lower satisfaction of the need for autonomy, which in turn produces higher negative affect among participants. The findings point towards the importance of considering the specific role of the psychological need for autonomy in the materialism–well‐being link.     

Case method strategies for teaching sexual ethics to relativists and skeptics

Many undergraduates are culturally shaped to avoid making ethical judgments. They spontaneously adopt relativist and skeptical strategies such as “It all depends,” or “Whose morality?” or “Who's to say?” as ways of fending off the challenge of making moral decisions. The current tsunami that is washing away traditional sexual norms is both a result and a cause of this cultural shift. Case studies can mitigate this decline and help students to grow in both confidence and ability to make good ethical judgments. The case method, used with a Socratic pedagogy, engages imagination and counters the deficits in empathy found in many contemporary students. It moves students toward understanding morality itself. Against skepticism, it assists students in exercising practical reason, culminating in decision. Five cases invite students to overcome extreme relativism, to look for and evaluate relevant differences, and to enter into ethical discussion with other students on the sexual issues they face in their college years.     

Less is more: Online consumer ratings' format affects purchase intentions and processing

Online customer ratings of products and services are commonplace in e‐commerce; however, the format in which these ratings are presented to consumers can vary. Although not anticipated by classical models of decision making, latter models such as prospect theory and feelings‐as‐information theory suggest that the presentation format of online customer ratings could affect subsequent consumer decision making. In the present research, 3 empirical studies test whether online customer ratings' formats differentially affect consumer purchase intentions. The results offer support for feeling‐as‐information theory and suggest that online ratings presented in a mean (vs. distribution) format result in higher purchase intentions as a result of increased processing fluency. Implications for the presentation of online consumer ratings in e‐commerce, based on these findings, are addressed.
