Any Size for a Dollar: The Effect of Any‐Size‐Same‐Price Versus Standard Pricing on Beverage Size Choices

Overconsumption of sugary drinks is linked with obesity. These beverages have been the target of recent public health policies, and, simultaneously, some firms have altered their pricing of such beverages, including charging the same price for all beverage sizes (“any‐size‐same‐price” pricing). We compare the effect of any‐size‐same‐price pricing versus standard pricing on soft drink beverage size choices and further explore the effect of this firm lever under different health‐related policy situations. Overall, we show that any‐size‐same‐price pricing increases consumers’ focus on the value of getting a good financial deal and thereby increases beverage size selections. Further, the allure of any‐size‐same‐price pricing prevents calorie postings from successfully reducing choice of larger sizes as occurs under standard pricing. However, a more graphic health intervention can reduce the appeal of larger sizes under any‐size‐same‐price pricing. Finally, the findings are not moderated by diet versus nondiet beverage selections, indicating that consumers do not perceive the value of larger sizes under any‐size‐same‐price pricing to come from getting more calories. We conclude by discussing how this work can improve the design of public health nutrition policies.     

社会阶层信号及其对人际水平社会互动的影响

社会阶层信号是指个体据以感知和判断他人社会阶层的一切线索, 人们通过加工这些微妙的线索便能判断出他人的社会阶层, 而他人的社会阶层在很大程度上决定着人们在人际水平的社会互动行为。以穿着打扮、面部特征和说话特点为例, 说明社会阶层信号对个体判断他人阶层的影响, 在此基础上围绕社会交换、社会公平和社会认同这三个动机视角归纳了社会阶层信号对人际水平社会互动的不同影响。针对社会阶层信号本身, 将来有必要探讨社会阶层信号功能弱化的问题; 由于社会阶层信号与社会阶层这一概念的相关度较高, 未来研究有必要阐述二者的联系与区别; 鉴于目前少有研究考察第三方的社会阶层信号如何影响人际水平社会互动的问题, 探索互动中第三方社会阶层信号的影响及其机制将会是对社会阶层心理学研究的一个重要推进。     

质疑星座决定人格特质的实证研究

星象学的基本假设是一个人出生时的星运位置可以决定其人格特质和重大际遇。本研究以16PF为工具,测查了165名大一学生,并按被试的出生日期和时辰确定了其星座。总的来说,结果不支持星座决定人格倾向的理论。     

Increasing driver yielding and pedestrian signaling with prompting, feedback, and enforcement

The effects of an intervention package on drivers' yielding to pedestrians and on pedestrians' signaling their intention to cross the street were assessed using a multiple baseline design. The intervention, which consisted of publicly posted feedback on the percentage of motorists yielding to pedestrians, small signs prompting pedestrians to engage in appropriate crossing behavior, and an enforcement program involving the use of warning tickets and feedback fliers, was sequentially introduced on two streets. The intervention more than doubled the percentage of motorists yielding to pedestrians and increased the percentage of pedestrians signaling their intention to cross the street to over 13% from a baseline level of less than 1%. Near misses involving pedestrians decreased by more than 50% on the narrower of the two streets.     

Mechanisms behind hazard perception of warning signs: An EEG study

Warning signs are the most effective way to alert people to hazards in the industries, architecture, and transportation. To better understand how these warning signs prompted hazard, this study investigated the intrinsic mechanism of hazard perception of warning signs, including warning words (low versus high hazard levels) and surrounding shapes (upright triangle versus circle). We recruited 18 participants and recorded electroencephalogram (EEG). We found that a combination of high-hazard-level words and an upright triangle shape significantly elicited more negative N300 and increased theta-band (3–8 Hz) synchronization, but reduced beta-band (15–30 Hz) desynchronization. The N300 component represented the emotional arousal strength, theta oscillations reflected the engagement of retrieval of emotional experiences from episodic memory, and beta oscillation connoted the semantic encoding. Thus, these findings suggested that a high-hazard-level combination had the ability to obtain high priority in cognitive processing. The EEG pattern changes allowed us to assess whether the hazard perception of warning signs was high or low, which could be an accurate indicator to better evaluate the design of warning signs.

Zur Rekonstruktion der Philosophischen Hermeneutik

Towards a reconstruction of philosophical hermeneutics. Following Nietzsche, Heidegger and, on the other hand, Cassirer and Wittgenstein, a philosophy of interpretation, i.e. a relativism of world-views, is at present increasing in continental as well as in analytical philosophy. From the basis of a critical fallibilism the shortcomings of the new epistemological antirealism are pointed out in general, and, hence, consequences are drawn for the more specialized case of metahermeneutics (hermeneutics being defined as a sort of pragmatical semiotics). A combination of realistic and antirealistic elements is recommended as unevitable. According to this, firstly, the key-concepts of hermeneutics must be differentiated, and, secondly, a fundamental set of criteria can be established that bridges the gap between metahermeneutics and hermeneutical practice.

Using public feedback to increase contributions to a multipurpose senior center

Multipurpose senior centers are expanding their services to meet the demands of a growing population. Unfortunately, federal agencies have not matched this expansion with monetary support. Many senior centers hold fund-raisers to supplement their budgets, but the impact of these projects is rarely evaluated. This study assessed the effectiveness of a public posting strategy designed to increase donations to an ongoing fund-raiser for a multipurpose senior center. The fund-raiser, "Coupons for Caring," consisted of senior volunteers clipping grocery coupons from newspapers, sorting them, and attaching them to their respective products in local grocery stores. Grocery store customers were given the option of donating the coupons to the senior center or redeeming them when they purchased the products to which the coupons were attached. In the experimental condition, signs were posted that included visual and written instructions, feedback on the value of coupons donated by customers the previous week, and feedback on the overall amount of money donated to the senior center. The signs were posted near each cashier stand and at the front entrances of the grocery stores in a multiple baseline across grocery stores. The percentage of coupons donated to the senior center increased at each store after the signs were posted.     

Ergonomic Design Improves Cross-Cultural Road Sign Comprehension

BackgroundTraffic sign design can have a substantial impact on road safety and traffic flow. The current study had three objectives: 1) Cross-validate the importance of ergonomic sign design; 2) Evaluate the ability of ergonomics experts to predict sign comprehension by the average driver; 3) Offer improved sign designs for poorly designed road signs. In a previous study (Ben Bassat et al., 2019), human factors and ergonomics experts evaluated several alternative designs for 31 different road signs, based on three ergonomics criteria – familiarity, standardization, and message/symbol compatibility. Some of these signs were tested in the current study and the correlation between the results of the two studies was analyzed.MethodIn this study, 805 licensed drivers from five countries were tested on their comprehension of 24 conventional signs and 32 alternative signs. Signs were individually presented on a screen and as soon as the participant decided on the meaning, the sign disappeared, and an experimenter wrote the stated meaning. The verbal responses were coded as correct (perfectly or partially), wrong, or opposite of the true meaning. Sign identification response time was also recorded.ResultsIn all countries across all signs, more drivers comprehended the alternative ergonomically superior signs, and the identification response times were shorter for these sign designs. Furthermore, the correlation between ergonomics experts' ratings as found in previous study and the percent of comprehension for each sign design was statistically significant and positive with r = 0.61.ConclusionsRoad signs should be designed according to ergonomics-based criteria. Human factors experts' opinions can be a useful tool in improving the design of poorly comprehended signs (or icons) and in designing new signs (or icons).
