Choice theories: What are they good for?

Simonson et al. present an ambitious sketch of an integrative theory of context. Provoked by this thoughtful proposal, I discuss what is the function of theories of choice in the coming decades. Traditionally, choice models and theory have attempted to predict choices as a function of the attributes of options. I argue that to be truly useful, they need to generate specific and quantitative predictions of the effect of the choice environment upon choice probability. To do this, we need to focus on rigorously modeling and measuring the underlying processes causing these effects, and use the Simonson et al. proposal to provide some examples. I also present some examples from research in decision-making and decision neuroscience, and argue that models that fail, and fail spectacularly are particularly useful. I close with a challenge: How would consumer researcher aid the design of real world choice environments such as the health exchanges under the Patient Protection and Affordable Care Act?     

Counting the Faithful: Measuring Local Religious Contexts in the United States

This study compares the estimates of religious composition of counties in the United States from three independent datasets: the 2010 Religious Congregational Membership Study (RCMS); the 2010 Infogroup Congregational membership data (INFO); and the Gallup Daily Poll—a large national survey with more than 1.3 million respondents. My analyses suggest that the estimates for most major religious groups from the three datasets are highly correlated to each other. In addition, the measures of local religious compositions from the three datasets successfully predict the religious composition of friendship networks in a large, nationally representative survey. These findings suggest that RCMS, the most widely used data source for measuring local religious composition in the United States, has a convergent and predictive validity. My analyses, however, also highlight important challenges in measuring geographic distributions of non‐Christian populations, as well as total religious populations in all religious traditions.     

The role of response inhibition in temporal preparation: Evidence from a go/no-go task

During the foreperiod (FP) of a warned reaction task, participants engage in a process of temporal preparation to speed response to the impending target stimulus. Previous neurophysiological studies have shown that inhibition is applied during FP to prevent premature response. Previous behavioral studies have shown that the duration of FP on both the current and the preceding trial codetermine response time to the target. Integrating these findings, the present study tested the hypothesis that the behavioral effects find their origin in response inhibition on the preceding trial. In two experiments the variable-FP paradigm was combined with a go/no-go task, in which no-go stimuli required explicit response inhibition. The resulting data pattern revealed sequential effects of both FP (long or short) and response requirement (go or no-go), which could be jointly understood as expressions of response inhibition, consistent with the hypothesis.     

Differential Effects of Short- and Long-Term Early Maternal Separation on Subsequent Maternal Behavior in Rats

Female Sprague-Dawley pups were separated from mothers every other day for 8 hr (long-term separation/LTS), 4 hr (short-term separation/STS), or 0 hr (no separation/NS) from postnatal day 2–20. In adulthood, they were mated and tested for maternal behaviors during two lactations. It was expected that females separated from mothers as pups would show deficits in maternal behavior as adults. Contrary to expectations, LTS showed better nest building and grouped young faster during both lactations. LTS were first to display aggression and displayed more aggression during the second lactation. Notably, while some measures decreased from first to second lactation in NS and STS, LTS maintained levels of maternal care. These results suggest that extended periods of maternal separation may exaggerate some aspects of maternal behavior.     

Beauty is in the sex of the beholder: An examination of the effects of interviewer characteristics on assessments of respondent attractiveness

Research exploring the effects of physical attractiveness frequently assesses attractiveness by employing subjective appraisals by independent raters. However, there is reason to believe that rater characteristics – especially their sex – may systematically bias subjective ratings of physical attractiveness. The current study explores this possibility by analyzing data from the National Longitudinal Study of Adolescent Health (N = 13,330). Analyses of these data revealed that ratings of physical attractiveness are significantly influenced by the sex of the interviewer/rater. Specifically, male raters were significantly less likely than female raters to assess males as attractive, very attractive, and very unattractive. The results are explained within the context of evolutionary psychology and illustrate a methodological concern for research on physical attractiveness.     

如何唤起和缓解重大损失情绪—— 来自行为和脑成像的证据

本研究在没有真实伤害的情况下研究重大损失情绪及相应的脑机制。通过一系列行为和脑成像实验, 研究者们摸索出了可靠诱发重大损失情绪的范式, 并从对比效应和金钱补偿角度初步探讨了缓解这种情绪的方法。研究发现, 由于自我防御机制的存在, 抑制了被迫接受条件下重大损失情绪的唤起, 但却成功唤起了被迫选择条件下重大损失的情绪。此外, 研究还发现, 金钱补偿和对比效应都是缓解重大损失情绪的有效策略。本研究不仅有利于认识重大损失情绪的信息加工机制, 而且也为涉及重大损失情绪的心理咨询和保险理赔制度等提供了行为和脑成像证据。     

中文双字词的具体性效应研究

通过词汇决定任务来考察中文双字词的具体性效应,并检验双重编码理论和语境有效性模型对具体性效应的预测。实验一在刺激单独呈现的条件下操纵词的频率,结果发现在低频的情况下对抽象词的判断时间显著长于具体词,但是在中频情况下没有显著差异;实验二用低频具体词和低频抽象词做重复启动实验,发现重复启动不能消除具体性效应;实验三为低频具体词和低频抽象词提供句子语境,结果发现在一致性句子语境条件下具体性效应消失。以上实验结果既不完全符合双重编码理论的预测,也不完全符合语境有效性模型的预测。     

并列和偏正结构双字合成词的注视位置效应

采用EyeLink II眼动仪, 选取并列结构和偏正结构两种类型的目标词, 要求大学生被试阅读包含有目标词的句子, 以探讨两种双字合成词的注视位置效应。结果发现：在阅读并列和偏正结构的目标词时, 单次注视条件下读者往往将首次注视定位于词的中心位置, 多次注视时首次注视往往落在词的开端部分; 当首次注视落在词的开端时再注视该词的概率增加, 而且再注视往往落在词的结尾部分。结果提示：在单次注视条件下存在偏向注视位置; 双字合成词结构不影响偏向和最佳注视位置; 研究结果支持“战略-战术”模型。     

汉字笔画数对注视位置效应的影响

采用EyeLink 2000眼动仪,选取四种不同类型的双字词（首字和尾字均为多笔画汉字;首字为多笔画汉字,尾字为少笔画汉字;首字为少笔画汉字,尾字为多笔画汉字;首字和尾字均为少笔画汉字）,要求被试阅读包含有目标词的句子,以探讨汉字笔画数对注视位置效应的影响。结果发现,单次注视条件下,读者往往将首次注视定位于词的中心位置,多次注视时首次注视往往落在词的开头部分;但是当首字为多笔画汉字时,相较于首字为少笔画汉字,读者对目标词的首次注视更多地落在词的首字上。首字和尾字笔画数共同影响读者对目标词的再注视概率。研究结果支持“战略-战术”模型。     

Colour correspondence effects between controlled objects and targets

It is increasingly popular to use movement trajectories as a measure of mental processes related to task performance. Often this is accomplished by moving a cursor to a target on a computer screen. However, the relation between features of the cursor and the targets is rarely, if at all, considered. In five experiments, we examined whether moving a cursor to a target was affected by the relation between their colours, even when this relation was task irrelevant. In Experiments 1–3, a mouse-controlled cursor was moved to one of two coloured targets. Results showed colour correspondence effects in latency to initiate a response, duration of movement times, and movement trajectories when the relationship between cursor and target colours was task relevant (Experiment 1) and when only the cursor colour was task relevant (Experiment 2), but not when only the target was task relevant (Experiment 3). Follow-up experiments using single targets showed that colour correspondence effects occurred as long as attention was dedicated to the colour of the cursor, even when neither the cursor nor the target colour was relevant to selecting the correct movement (Experiments 4 and 5). Furthermore, when the relation between cursor and target colours is task irrelevant, colour correspondence effects for response initiation times are uncorrelated with those for movement times and movement trajectories. We interpret the observed correspondence effect in terms of response coding, although attention cueing may also play a role, and suggest that greater consideration of cursor features is needed when examining movement trajectories in choice reaction tasks.
