移动购物更快吗?决策场景与思维模式的相容性

既有文献对消费者延迟选择影响因素的研究, 主要集中于决策复杂度、决策者特质或情绪, 少有对决策场景进行深入探讨。互联网购物时代, PC端与手机端已成为重要的消费场景。针对手机端是否会加快消费者决策过程的问题目前也存在不一致的结论。本文引入决策双系统理论, 力图解释以往看似冲突的结论。消费者的购买决策模式, 不仅会受到决策任务(产品价格)的影响, 还会受到决策场景(购买终端)影响。当场景与决策任务使消费者启动的思维模式相一致时, 会提升决策流畅度, 降低延迟选择。本文发现, 移动端(PC端)与低(高)价格产品更容易激发相容的经验性(理性)思维, 降低延迟选择倾向。反之, 则会同时启动两种相左的决策思维, 增加延迟选择倾向。本文从场景启动与价格启动视角, 将以往消费者单一的决策思维模式, 拓展到多因素启动的思维模式相容性问题; 同时本文通过探究延迟选择问题, 对价格策略与场景化营销带来启示。     

Is the victim Max (Planck) or Moritz? How victim type and social value orientation affect dishonest behavior

Does the potential victim of dishonest behavior—a family or a bank, a pensioner or an insurance firm—affect the propensity to engage in such behavior? We investigate the effect of victim type—an individual person or an impersonal institution—on dishonest behavior and test whether it interacts with potential perpetrators' social value orientation (prosocial or proself). In a between‐subjects design, we allowed experimental participants (N = 368) to misreport private information in order to increase (decrease) their profit (loss) at the expense of either another participant or the experimenter's budget. Both prosocials and proselfs engaged in dishonesty, but proselfs did so much more. Furthermore, prosocials reduced their dishonesty when the victim was another person, rather than an institution, but proselfs did not. A direct implication is that the dishonesty of prosocials may be curbed by increasing the salience of the adverse effect their dishonesty has on other individual people but that such interventions will not be effective for proselfs. In contrast with recent results, we did not find a general effect of increased dishonesty under a loss (vs. gain) frame.     

Executive functions and linguistic performance in SCD older adults and healthy controls

Subjective cognitive decline (SCD) might represent the preclinical phase of Alzheimer’s disease. Given the interest to characterize it, the present study explores (1) if there are differences in lexical retrieval (LexR) and sentence comprehension (SComp) between SCD and matched controls, and (2) the predictive value of demographic variables and executive functions in relation to LexR and SComp in each group. A sample of 135 participants voluntarily took part in this study (66 with SCD). They all completed the Trail Making, the Stroop, the Boston Naming, and the ECCO-Senior tests, as well as verbal fluency tasks (VF). Results show that (1) groups differ in LexR and in inhibition efficiency, and (2) VF is explained by years of formal education, particularly in the control group; SComp in the most complex items seems to rely in different strategies, related to flexibility in controls and to inhibition efficiency in SCD patients.     

Why reread? Evidence from garden-path and local coherence structures

Two eye-tracking experiments were conducted to compare the online reading and offline comprehension of main verb/reduced relative garden-path sentences and local coherence sentences. Rereading of early material in garden-path reduced relatives should be revisionary, aimed at reanalysing an earlier misparse; however, rereading of early material in a local coherence reduced relative need only be confirmatory, as the original parse of the earlier portion of these sentences is ultimately correct. Results of online and offline measures showed that local coherence structures elicited signals of reading disruption that arose earlier and lasted longer, and local coherence comprehension was also better than garden path comprehension. Few rereading measures in either sentence type were predicted by structural features of these sentences, nor was rereading related to comprehension accuracy, which was extremely low overall. Results are discussed with respect to selective reanalysis and good-enough processing.     

The gender effect in 3D-Mental-rotation performance with familiar and gender-stereotyped objects – a study with elementary school children

The study examined the influence of gender-stereotyped stimuli rotated in depth on children’s mental-rotation performance. Participants included 321 elementary school children who completed three-dimensional mental-rotation tasks with either male- or female-stereotyped stimuli (M-MRT-3D/F-MRT-3D). Results suggest that in-depth tasks are very difficult for second graders. No gender effect was found in the mental-rotation performance of 7- to 9-year-old children; however, task understanding indicates gender differences. For fourth graders, a significant interaction of gender and stimulus type could be demonstrated. Furthermore, results indicate that fourth-grade boys tend to guess more often in tasks with stimuli consistent to the respective own gender. In addition, regression analyses showed that next to grade and perceptual speed, the perceived level of stimulus familiarity predicted performance. Considering a possible link between dimensionality and familiarity, the influence of the gender-stereotyped stimuli on children’s confidence and task understanding as well as on transformational processes and strategy efficiency is discussed.     

Career specialty choice: A combined research-intervention project

This research describes and evaluates a workshop aimed at promoting career specialty choice and examines relationships between measured career specialty interests, work values, and personality type. Three consecutive classes of second-year medical students (N = 161) participated in a two-session specialty choice workshop. All participants in the study rated the usefulness of the workshop and reported their level of specialty choice certainty and satisfaction. They also responded to measures of medical specialty preference, work values, and personality type. Results indicated two distinct student subgroups of career-specialty-decided and -undecided students. The former subgroup evidenced more stability and certainty of specialty choice as well satisfaction with their choice. Both groups of students reported having benefited from the workshop. Significant gender differences in the relationships between scores on a measure of medical specialty preference and scores on measures of work values and personality emerged. Implications are discussed in terms of the differential career counseling needs of students either decided or undecided about their career specialty choices.     

不同文章难度条件下文化特征类型熟悉度对阅读理解的影响

该研究考察了非英语专业具有不同英语语言水平学习者在不同难度条件下两种文化特征熟悉度对阅读理解的影响。研究发现：（1）语言水平高,或对材料背景熟悉的学习者可通过调用熟悉的文化背景知识帮助阅读理解,其得分均高于低水平,或对材料不熟悉的学习者;（2）在熟悉的文化背景条件下,当材料难度与学习者语言水平基本一致时,语言水平低的学习者也可较好地运用熟悉的文化背景知识帮助阅读理解。实验结果表明：文化特征的内容熟悉度和英语语言水平（或文章难度）对阅读理解起着重要作用,语言水平越高,作用越大。     

驾驶经验和危险类型对驾驶员危险检测的影响

结合反应时和信号检测方法,考察不同危险类型下驾驶员危险检测的特点。35名新手和35名有经验驾驶员依次完成一个反应时测试和一个信号检测任务。结果发现：新手对明显和隐藏危险的反应时间比有经验驾驶员长。与隐藏危险相比,驾驶员对明显危险的敏感性高、判断标准低。驾驶员对两类危险的反应时间长是因为他们的判断标准严格。研究结果表明,驾驶员危险检测的特点随着危险类型不同而变化。     

同时线索化条件下儿童返回抑制的容量

返回抑制是对先前注意过的目标再次做出反应的时候反应时延长的一种现象。返回抑制具有一定的生物学意义,忽略已经注意过的位置(或客体),使得有机体可以更加有效的注意新的内容。基于这一点,返回抑制现象应该可以在多个已经注意过的位置出现,这便是返回抑制的容量问题。在本研究中,采用同时呈现的线索化方式,考查8岁、10岁儿童在不同的实验任务——觉察任务和辨别任务——中的返回抑制容量。结果发现觉察任务中,10岁组儿童和8岁组儿童最多在5个线索化位置上出现返回抑制,但8岁年龄组的返回抑制容量缺乏稳定;辨别任务中,10岁年龄组只在一个位置上出现返回抑制,而8岁年龄组并没有明显返回抑制现象出现。年龄因素和任务类型对儿童返回抑制容量都产生了一定程度的影响。
