Testing take-the-best in new and changing environments

Take-the-best is a decision-making strategy that chooses between alternatives, by searching the cues representing the alternatives in order of cue validity, and choosing the alternative with the first discriminating cue. Theoretical support for take-the-best comes from the “fast and frugal” approach to modeling cognition, which assumes decision-making strategies need to be fast to cope with a competitive world, and be simple to be robust to uncertainty and environmental change. We contribute to the empirical evaluation of take-the-best in two ways. First, we generate four new environments—involving bridge lengths, hamburger prices, theme park attendances, and US university rankings—supplementing the relatively limited number of naturally cue-based environments previously considered. We find that take-the-best is as accurate as rival decision strategies that use all of the available cues. Secondly, we develop 19 new data sets characterizing the change in cities and their populations in four countries. We find that take-the-best maintains its accuracy and limited search as the environments change, even if cue validities learned in one environment are used to make decisions in another. Once again, we find that take-the-best is as accurate as rival strategies that use all of the cues. We conclude that these new evaluations support the theoretical claims of the accuracy, frugality, and robustness for take-the-best, and that the new data sets provide a valuable resource for the more general study of the relationship between effective decision-making strategies and the environments in which they operate.     

伦理消费者为何“言行不一”:解释水平的视角

伦理消费(Ethical consumption,EC)是指消费者在获取、使用或处置产品时考虑到个人消费行为对社会、环境或动物福祉的影响。虽然伦理消费日渐流行,但在金钱支付时伦理消费的态度却往往难以转化为实际的行为,即言行不一。本文从解释水平理论视角出发,以"心理距离→解释水平→个体反应"为分析框架展开。从时间维度上来说,在态度评价阶段和产品选择阶段两个时间点上,消费者与伦理产品的心理距离远近不同,分别激活了高低解释水平表征;高低解释水平下个体在动机和认知上又存在诸多差异,这种差异导致两个阶段的反应不同,继而出现伦理消费者态度与行为的分离。未来研究应重点关注如何根据解释水平理论有效提高伦理消费行为。     

Post-encoding emotional arousal enhances consolidation of item memory,but not reality-monitoring source memory

The current study examined whether the effect of post-encoding emotional arousal on item memory extends to reality-monitoring source memory and, if so, whether the effect depends on emotionality of learning stimuli and testing format. In Experiment 1, participants encoded neutral words and imagined or viewed their corresponding object pictures. Then they watched a neutral, positive, or negative video. The 24-hour delayed test showed that emotional arousal had little effect on both item memory and reality-monitoring source memory. Experiment 2 was similar except that participants encoded neutral, positive, and negative words and imagined or viewed their corresponding object pictures. The results showed that positive and negative emotional arousal induced after encoding enhanced consolidation of item memory, but not reality-monitoring source memory, regardless of emotionality of learning stimuli. Experiment 3, identical to Experiment 2 except that participants were tested only on source memory for all the encoded items, still showed that post-encoding emotional arousal had little effect on consolidation of reality-monitoring source memory. Taken together, regardless of emotionality of learning stimuli and regardless of testing format of source memory (conjunction test vs. independent test), the facilitatory effect of post-encoding emotional arousal on item memory does not generalize to reality-monitoring source memory.     

结构化面试中评分量表对评分准确性的影响

采用2(组内变量:量尺大小(25分和9分))×2(组间变量:评分方法(相对和绝对))的混合实验设计探讨评分量表对115名大学生新手评委评分准确性的影响。对于评分准确性,采用Cronbach1955年提出的四个指标,Elevation(EL)、Differential elevation(DE)、Stereotype accuracy(SA)、Differential Accuracy(DA)。结果发现,评分方法只在SA上主效应显著,量尺大小在只在DA上主效应边缘显著,评分方法和量尺大小在DE、SA和DA三个指标上均有交互作用。总体上看,在结构化面试评分中,对于评分准确性,相对评分量表优于绝对评分量表,小量尺量表优于大量尺量表。     

To Be Philosophical, Even if One Will Not Be a Professional Philosopher: The Aim and Mission of Philosophy Education

In contemporary society,the number of students who major in philosophy at universities has decreased.Furthermore,as Richard Mervyn Hare said many years ago,"Most of my pupils are going to be,not professional philosophers,but businessmen,politicians,schoolmasters,clergymen,lawyers,journalists,civil servants,and,indeed,almost anything but philosophers;and a substantial number of these may be expected to reach the highest ranks of their professions" (Hare 1971,39).     

Power of the desired self: Influence of induced perceptions of the self on reasoning

This research shows that the motivation to posses a desired characteristic (or to avoid an undesired one) results in self-perceptions that guide people’s use of base rate in the Lawyer–Engineer problem (Kahneman & Tversky, 1973). In four studies, participants induced to believe (or recall, Exp. 2) that a rational cognitive style is success-conducive (or an intuitive cognitive style failure-conducive) subsequently viewed themselves as more rational and relied more on base rate in their probability estimates than those induced to believe that a rational cognitive style is failure-conducive (or an intuitive cognitive style success-conducive). These findings show that the desired self had an influence on reasoning in the self-unrelated lawyer–engineer task, since the use of base rates was mediated by changes in participants’ perceptions of their own rationality. These findings therefore show that the desired self, through the working self-concept that it entails, constitutes another factor influencing people’s use of distinct modes of reasoning.     

the role of career stress in the relationship between maladaptive perfectionism and career attitude maturity in south korean undergraduates

Given the central role of career stress in college students' lives, this research examined whether career stress mediated the relationship between maladaptive perfectionism and career attitude maturity in a sample of 185 undergraduate students in South Korea. The results indicated that career ambiguity stress, as measured by a career stress inventory, fully mediated the relationship between maladaptive perfectionism and career attitude maturity. That is, maladaptive perfectionism correlated with greater levels of career ambiguity stress, and greater career ambiguity stress correlated with an unconstructive level of career attitude maturity. The authors discuss the findings' implications for career counselors in college settings.     

School competence and emotional/behavioral problems among Norwegian school children as rated by teachers on the Teacher Report Form

Of 1,409 eligible children aged 6-13 years in grades 1 to 7 who were randomly selected from a national sample of Norwegian schools, 858 participated in the present study (60.9%). The sample was stratified by school centrality, region and size of grade cohort. The teachers assessed their children's academic performance, adaptive school functioning, and levels of emotional/behavioral problems using the 2001 version of the Teacher Report Form (TRF). Only one child was randomly selected from each grade cohort. Girls had significantly higher scores than boys in the Working Hard, Appropriate Behavior, Learning, and Total Adaptive Functioning domains. For girls, only the Working Hard domain was of medium effect size. While boys had significantly higher scores than girls on Attention, Thought Problems, Rule-Breaking, Aggression, Externalizing Problems and Total problems, only Attention Problems showed a medium effect size. Significant sex by age interaction effects were also found for Rule-Breaking, Externalizing, Internalizing, Anxious-Depressed and Total Problems. In all these comparisons, 10-13-year-old boys had significantly higher scores than 6-9-year olds, while girls had similar problem levels across age groups. Our mean Total Problems score (17.2) was lower than the grand mean (21.6) reported in a multi-country comparison but higher than in another Norwegian large-scale survey. Overall, our findings indicate that teachers in Scandinavia report, just as do parents, relatively low levels of emotional/behavioral problems among school-aged children.     

Religious Pathways from Adolescence to Adulthood

Prior research suggests the significance of religion for development and well‐being in adolescence and beyond. Further, new developments and applications of statistical methods have led to ways of better accounting for the multidimensional nature of religiosity (e.g., latent class analysis), as well as the dynamic aspects of religiosity (e.g., latent growth curve models). Yet, rarely, if ever, are both features of religiosity incorporated and examined together. Therefore, we propose and conduct a latent class analysis using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to identify seven distinct pathways of religiosity that involve independently changing levels of religious affiliation, religious service attendance, personal importance of religion, and prayer from adolescence to adulthood. We also show how individuals’ religious pathways are related to gender, race, parents’ education, their own education, and family formation experiences in the transition to adulthood. Our findings inform the study of how multiple dimensions of religiosity take shape across adolescence and the transition to adulthood, and suggest a new way for measuring the dynamics of religiosity in studies of the impact of religion across the life course.
