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 Training Effect of Working Memory Based on Central Executive System Intervention in Older Adults: A Randomized Controlled Study

This article aims to investigate the training effect of working memory in older adults. A total of 43 older adults ranging in age from 75 to 95 were recruited to participate in the study. A battery of tests regarding central executive function, working memory, and primary mental ability were administered in the pretest phase. A total of 22 of the older participants were randomly selected as the intervention group. Thirteen days after the pretest, the same tests were administered to all of the participants. The results showed that (1) the differences in the pretest and posttest gains in the task-switching tests were not significant between the intervention group and the control group; (2) the performance of the intervention group on the operation working memory span test and the graphical reasoning test showed a significant improvement after the intervention compared with the control group who did not receive the intervention. We can conclude that the working memory of old adults may be improved by an intervention targeting the central executive system. However, this possibility needs further investigation.     

Conceptual response distance and intervening keys distinguish action goals in the Stroop color-identification task

In previous studies, a physical response-distance effect was found in the two-choice Stroop color-identification task, with the Stroop effect being larger when the two response keys were physically close together than when they were far apart. In the present study, we found a conceptual response-distance effect, with the Stroop effect being larger when the response keys were conceptually close (labeled as “5” and “6”) than when they were conceptually far (labeled as “1” and “9”). Moreover, a response-distance effect due to pure physical distance was not evident; rather, the effect was found only when additional keys were placed between the two far response keys. These results are in agreement with a view that response keys are coded as action goals, with farther conceptual distance and additional keys helping distinguish the action goals. The results are difficult to reconcile with accounts that place emphasis on the physical separation of the effectors or their inanimate extensions.     

You’re Better Respected When You Carry Yourself as a Man: Black Men’s Personal Accounts of the Down Low “lifestyle”

Although the notion of a down low life style, called various things at various times, has a long history in the black community, the past few years have been marked by an exponential increase in attention of this phenomenon in both the mainstream press and scholarly work. However, much of this work has focused on exploring whether men on the down low present a unique threat for HIV infection to black women. Currently, there exist very few scholarly works exploring the lives of black men who have sex with men and women that specifically address their own experiences living on the down low or how these men personally define what it means to be on the down low. In this article, we explore why black men who have sex with men and black men who have sex with men and women, including those who self-identify as gay, bisexual or as being on the down low, come to use the down low label and what it means to them to be on the down low.     

Improving Epistemological Beliefs and Moral Judgment Through an STS-Based Science Ethics Education Program

This study develops a Science–Technology–Society (STS)-based science ethics education program for high school students majoring in or planning to major in science and engineering. Our education program includes the fields of philosophy, history, sociology and ethics of science and technology, and other STS-related theories. We expected our STS-based science ethics education program to promote students’ epistemological beliefs and moral judgment development. These psychological constructs are needed to properly solve complicated moral and social dilemmas in the fields of science and engineering. We applied this program to a group of Korean high school science students gifted in science and engineering. To measure the effects of this program, we used an essay-based qualitative measurement. The results indicate that there was significant development in both epistemological beliefs and moral judgment. In closing, we briefly discuss the need to develop epistemological beliefs and moral judgment using an STS-based science ethics education program.     

When the “Charm of Three” Fades: Mental Imagery Moderates the Impact of the Number of Ad Claims on Persuasion

Given the prevalence of imagery appeals in today’s marketplace, the current research studies the role of mental imagery in how consumers process and react to advertisements with different numbers of ad claims. Past research has proposed “three” as the magical number of ad claims that maximizes persuasion, with more than three ad claims increasing skepticism and reducing evaluation. In the current research, we replicate this so-called “charm of three” effect, but only when consumers do not engage in mental imagery; when they do, however, we find that the effect is moderated, in that more ad claims beyond three produces more favorable product evaluation. Additionally, we provide evidence that the moderating effect of mental imagery is driven by transportation and skepticism toward the ad claims, with mental imagery increasing transportation and decreasing skepticism when there are more than three ad claims. Our research contributes to a better understanding of the “charm of three” effect, its boundary conditions, and underlying mechanism.     

基于成本最小化信息的社会性意图识别：来自脑电和行为的证据

与已有研究着重考察如何识别客体导向性意图(动作以物理对象为目标, 而不涉及其他人)不同, 本研究对人们如何识别社会性意图(动作以指向社会主体为目标以影响对方的交互行为)进行了探讨。基于两交互主体在整体层面应遵循效用最大化的分析, 提出当A协助B达成目标状态所需要的成本小于B单独实现该目标状态所需要的成本时(简称为成本最小化信息), 其可被识别为具有社会性意图。通过在B面前设置栅栏的方法操纵成本最小化信息, 以指示不同意图类型的脑电μ抑制程度、对不同变化的敏感性(辨别力)为指标, 对该假设进行了检验。结果显示, 相比客体导向性意图的控制条件(即A将目标物苹果放置在石头前), 当A将目标物苹果放置在被栅栏挡住的B前, 其动作可减少B单独获取该苹果的动作成本, 即符合成本最小化条件时, μ的抑制程度更高(实验1), 且对结构改变(某两个动画中充当相同角色的智能体互换)的辨别力更强, 但对角色交换(某个动画中两个智能体的角色交换)的辨别力更弱(实验3a); 而当栅栏不存在时, 虽然A的运动路径与实验1相同, 但A将苹果放置在B前的成本大于B自身获取苹果的成本, 即不符合成本最小化条件, 条件间μ抑制的差异消失(实验2), 且对不同动作模式中变化的辨别相当(实验3b)。鉴于已有研究表明社会性意图所诱发的μ抑制强于客体导向性意图, 且人们对存在社会性意图的两个智能体间的结构改变更容易辨别, 而对角色交换不敏感, 故上述结果揭示, 两个个体的行为是否满足成本最小化影响人们对动作意图的识别, 支持成本最小化信息是社会性意图识别线索的观点。

居危思变?工作不安全感对创新行为的差异化影响?

企业往往在员工管理和组织创新上处于“两难困境”——难以提供稳定工作但又不得不依赖员工实现组织创新, 这就使得研究员工工作不安全感对创新行为的影响至关重要。企业员工遭遇不同环境威胁带来的工作不安全感时, 创新行为存在差异。本文在威胁焦点下深化工作不安全感概念, 并基于“以变量为中心”和“以人为中心”的研究思路, 探讨其对创新行为的差异化影响过程。首先, 结合环境威胁来源与主观感知, 把工作不安全感分为岗位焦点工作不安全感和人员焦点工作不安全感两个维度, 并将编制测量量表。其次, 期望运用纵向研究设计, 通过分析多时点的员工-主管配对数据, 基于情境调节焦点和工作激情的链式中介作用, 来揭示岗位焦点工作不安全感对创新行为的负向影响, 以及人员焦点工作不安全感对创新行为的倒U型影响。最后, 将采取“以人为中心”的研究思路, 运用潜在剖面分析方法探讨工作不安全感潜在类型及其对创新行为的影响。研究结果将有助于推进工作不安全感的概念和效用研究, 也为企业如何有效促进创新提供对策建议。
