Opposing pupil responses to offered and anticipated reward values

Previous studies have shown that the pupils dilate more in anticipation of larger rewards. This finding raises the possibility of a more general association between reward amount and pupil size. We tested this idea by characterizing macaque pupil responses to offered rewards during evaluation and comparison in a binary choice task. To control attention, we made use of a design in which offers occurred in sequence. By looking at pupil responses after choice but before reward, we confirmed the previously observed positive association between pupil size and anticipated reward values. Surprisingly, however, we find that pupil size is negatively correlated with the value of offered gambles before choice, during both evaluation and comparison stages of the task. These results demonstrate a functional distinction between offered and anticipated rewards and present evidence against a narrow version of the simulation hypothesis; the idea that we represent offers by reactivating states associated with anticipating them. They also suggest that pupil size is correlated with relative, not absolute, values of offers, suggestive of an accept–reject model of comparison.     

认同理论视角下新员工组织社会化的定义及结构维度

组织社会化研究一直以来被批评缺少理论基础, 导致对组织社会化的本质和结构维度缺乏足够认识, 从而影响到在实证中如何测量员工组织社会化的程度。角色认同理论和社会认同理论可以为该研究提供理论基础。在对概念重新进行理论界定的基础上, 揭示了组织社会化本质是新员工角色及社会认同发展的过程。相应地, 组织社会化程度是一个两维度结构。未来研究应以此为基础进一步发展组织社会化量表和理论模型, 并依据认同理论改进实证研究方法。     

程序公正的测量及研究操纵

程序公正是指处理管理事务所依据的原则是否公正。普遍认可的程序公正原则包括一致性、避免偏见、准确性、可修正、代表性、道德与伦理原则。程序公正研究主要有测量和实验操纵两种研究范式。对程序公正的测量主要以单维为主,亦有少数多维测量量表;对程序公正的实验操纵主要以发言权为主,有少数研究对准确性、无偏性或综合几项原则进行操纵。未来研究应考虑程序公正的结构问题,对程序公正的操纵范围进行扩展、操纵方法考虑情景性,还需关注程序公正与程序不公正的差异。     

Do violent video games impair the effectiveness of in-game advertisements? The impact of gaming environment on brand recall, brand attitude, and purchase intention

The present study examined whether a violent video game impairs the effectiveness of in-game advertisements compared to a nonviolent video game. Participants recalled and evaluated in-game ads after navigating identical violent or nonviolent game scenarios. Participants' brand recall, recognition, and attitudes were comparatively lower after navigating the violent video game. Also, females in the violent game condition reported lower brand attitudes in comparison to males in the violent game condition, thus suggesting that the effects of gaming environment interacts with participants' gender. The findings supported the predictions of the limited capacity model of attention and cognitive priming effects. The results also extend previous studies on how violent media impair advertising effectiveness and provide practical implications for researchers and practitioners.     

Responding to partners' expression of anger: the role of communal motivation

The effects of communal motivation on reactions to relationship partners' expressed anger were examined. In Study 1, married couples reported on the communal strength of their marriage, their expressions of anger to their spouse, and relationship satisfaction. In Study 2, college students reported on the communal strength of their best friendships, those friends' expressions of anger, and their evaluations of and provision of support to those friends. In Study 3, communal motivation toward a stranger who expressed mild anger was manipulated and evaluation of that stranger was measured. In all three studies, low communal motivation was associated with more negative evaluations of angry partners, lower relationship satisfaction, and, in Study 2, lower support provision. In contrast, when communal motivation was high, these decreases either did not occur (Studies 1 and 3) or were diminished (Study 2), and in Study 2, partners' anger was associated with increased provision of social support.     

Deconstructing antenatal depression: What is it that matters for neonatal behavioral functioning?

This prospective study examined the variability within clinical characteristics of antenatal maternal depression and cortisol levels for associations with newborn infant behavior using the Neonatal Behavioral Assessment Scale (NBAS; T.B. Brazelton, 1984 ). Participants were 81 pregnant women at risk for perinatal depression given their histories of depression prior to pregnancy. We took into consideration not only whether the woman experienced antenatal depression but also whether the depression met diagnostic criteria and variability in timing (onset and occurrence) of antenatal depression and symptom severity. Infants of mothers who became depressed during pregnancy scored less optimally on a subset of the NBAS scales, specifically those scales related to infant neuroregulation. Among the clinical characteristics of depression, the fetus' overall exposure to mothers' depression (reflected in the mean) was most often and most strongly associated with NBAS scales. In terms of timing, third‐trimester exposure was significantly related to newborn behavior. The findings are discussed within the S.H. Goodman and I.H. Gotlib ( 1999 ) model for transmission of psychopathology to offspring of depressed mothers.

Generalized full-information item bifactor analysis

Full-information item bifactor analysis is an important statistical method in psychological and educational measurement. Current methods are limited to single-group analysis and inflexible in the types of item response models supported. We propose a flexible multiple-group item bifactor analysis framework that supports a variety of multidimensional item response theory models for an arbitrary mixing of dichotomous, ordinal, and nominal items. The extended item bifactor model also enables the estimation of latent variable means and variances when data from more than 1 group are present. Generalized user-defined parameter restrictions are permitted within or across groups. We derive an efficient full-information maximum marginal likelihood estimator. Our estimation method achieves substantial computational savings by extending Gibbons and Hedeker's (1992) bifactor dimension reduction method so that the optimization of the marginal log-likelihood requires only 2-dimensional integration regardless of the dimensionality of the latent variables. We use simulation studies to demonstrate the flexibility and accuracy of the proposed methods. We apply the model to study cross-country differences, including differential item functioning, using data from a large international education survey on mathematics literacy.     

Gender differences in adult word learning

In prior work, women were found to outperform men on short-term verbal memory tasks. The goal of the present work was to examine whether gender differences on short-term memory tasks are tied to the involvement of long-term memory in the learning process. In Experiment 1, men and women were compared on their ability to remember phonologically-familiar novel words and phonologically-unfamiliar novel words. Learning of phonologically-familiar novel words (but not of phonologically-unfamiliar novel words) can be supported by long-term phonological knowledge. Results revealed that women outperformed men on phonologically-familiar novel words, but not on phonologically-unfamiliar novel words. In Experiment 2, we replicated Experiment 1 using a within-subjects design, and confirmed gender differences on phonologically-familiar, but not on phonologically-unfamiliar stimuli. These findings are interpreted to suggest that women are more likely than men to recruit native-language phonological knowledge during novel word-learning.     

A study of Ghiselli's hobo syndrome

This study attempts to clarify conceptual and operational inconsistencies in the literature around “Ghiselli's hobo syndrome.” I propose that defining characteristics of hobo syndrome should include both the exhibition of frequent job movement behavior and positive attitudes about such behavior. This definition effectively differentiates the construct from other similar phenomena associated with frequent job movement (e.g., job/career mobility, protean careers). Using latent class cluster analysis of a diverse sample of 944 U.S. workers, it was empirically validated that a small number of individuals resembling the proposed characteristics of hobos did emerge as a distinct group (N = 42), providing person-centered evidence for the construct validity of hobo syndrome. The dispositional roots of hobo syndrome and work-related outcomes were also explored. It was found that individuals with high levels of openness to experience were likely to exhibit hobo syndrome, whereas impulsivity was not related to such tendency. Also, workers who were more likely to be categorized as hobos tended to report less positive views about their current jobs. Based on these findings, implications for research and practice are discussed.
