The gaze-cueing effect is a robust phenomenon which illustrates how attention can be shaped by social factors. In four experiments, the present study explored the interaction between the ethnic membership of the participant and that of the face providing the gaze cue. Firstly, we aimed to further investigate the differential impact of White, Black, and Asian faces on the gaze-cueing effect in White individuals. Secondly, we aimed to explore, for the first time, the impact of faces belonging to different ethnicities on gaze cueing in Chinese participants. The results allowed to rule out alternative accounts and showed that White participants exhibit a gaze-cueing effect for White and Asian faces, but not for Black faces, consistent with previous studies. As regards Chinese participants, the overall findings suggested a stronger gaze-cueing effect for White faces than for Asian faces. The results are discussed with reference to differences in the perceived social status of the various groups, pointing to the need of taking into account different cultural contexts. 相似文献
Multidimensional item response theory (MIRT) is widely used in assessment and evaluation of educational and psychological tests. It models the individual response patterns by specifying a functional relationship between individuals' multiple latent traits and their responses to test items. One major challenge in parameter estimation in MIRT is that the likelihood involves intractable multidimensional integrals due to the latent variable structure. Various methods have been proposed that involve either direct numerical approximations to the integrals or Monte Carlo simulations. However, these methods are known to be computationally demanding in high dimensions and rely on sampling data points from a posterior distribution. We propose a new Gaussian variational expectation--maximization (GVEM) algorithm which adopts variational inference to approximate the intractable marginal likelihood by a computationally feasible lower bound. In addition, the proposed algorithm can be applied to assess the dimensionality of the latent traits in an exploratory analysis. Simulation studies are conducted to demonstrate the computational efficiency and estimation precision of the new GVEM algorithm compared to the popular alternative Metropolis–Hastings Robbins–Monro algorithm. In addition, theoretical results are presented to establish the consistency of the estimator from the new GVEM algorithm. 相似文献
In this study, we examined attention and memory biases for aggressive information in two groups of college students. Individuals with fragile high self-esteem (n = 30) and individuals with secure high self-esteem (n = 30) first performed a dot-probe task investigating attention bias, followed by a memory task. Incidental free recall of words presented in the memory task was then completed to assess memory bias. Results revealed that individuals with fragile high self-esteem exhibited significant attention and memory biases for aggressive words compared with secure high self-esteem individuals. Attention bias for aggressive words was positively correlated with memory bias in individuals with fragile high self-esteem, but no correlation was found for individuals with secure high self-esteem. These findings suggest that individuals with fragile high self-esteem selectively attend to and remember aggression-related information. They may process information in ways that are congruent with an aggression-related schema. This study reveals the aggressive cognitive processes of individuals with fragile high self-esteem, which may be related to aggression. 相似文献
The recent reports of Wells Fargo and Morgan Stanley being engaged in widespread fraudulent sales practices in the retail banking industry make this field a timely and interesting area of study. The current study expands upon previous research examining retail banking deviance and seeks to further explore potential causes of such conduct. Specifically, the current study seeks to explore whether the underlying deviance is being taught by senior employees and also whether current ethics and compliance policies are adequate deterrents. To achieve this goal, the current study utilizes an approach mirroring a qualitative case study. Results indicate that new employees are being taught these fraudulent practices and that current ethics and compliance practices and policies are largely ineffective in curtailing such conduct. Informed by these findings, policy recommendations are presented. 相似文献
The episodic effect suggests that episodic prospection (imagining future events) can effectively reduce time discounting, the propensity to discount the value of delayed rewards relative to immediate ones. However, less clear is how episodic prospection modulates time preference. As engagement in episodic prospection usually evokes prospective emotions, it was proposed that episodic prospection might work by inducing prospective emotions. Although one previous study has attempted to provide evidence to the emotional account of the episodic effect, shortcomings in its experimental design make its conclusion questionable. In this study, we replicated previous experimental design with improvements to further test the effects of prospective emotion on time preference. By manipulating the emotional valency associated with episodic prospection in a delay discounting task, we found that positive episodic prospection attenuated time discounting; negative episodic prospection exacerbated time discounting; and episodic prospection did not shift time preference when prospective emotion is removed. These results were essentially identical to the result of the previous study. Together, these studies suggested that the effects of episodic prospection depended on prospective emotion. Thus, one cannot ignore prospective emotion if counting on episodic prospection to combat humans’ impulsive behaviours. 相似文献
According to recent theorizing, cognitive control and affective processing are closely linked. Specifically, it has been suggested that negative affect acts as a driving force for attentional adjustment. Empirical support comes from a study by van Steenbergen et al. (Psychol Sci 20:1473–1477, 2009) demonstrating that negative stimuli increase the congruence sequence effect (CSE), a behavioural marker that indexes attentional adjustment. In this research, we provide a theoretical analysis that identifies motivational orientation (approach vs. avoidance) as a potential moderator. To test this, we replicated the study by van Steenbergen et al. (2009) and additionally manipulated the motivational orientation of participants. Participants either gained extra money after task completion (gain-focused group) or lost money after task completion (loss-focused group). Results showed that negative stimuli boost attentional adjustment, but only in the loss-focused group. This finding highlights the role of motivation for recent theorizing on emotion-driven control.

The Brief Problem Monitor (BPM) is a 19-item instrument newly developed for screening children and adolescents for emotional and behavioral problems. The aim of this study was to investigate the psychometric properties of the youth-report and parent-report versions of the BPM (BPM-Y and BPM-P) among Chinese youth. Data was collected from two samples: a middle school student sample (n?=?1,246, girls?=?516 [41.4%]) and a community youth sample from families suffering adversity (n?=?383, girls?=?143 [37.3%]). We conducted a series of confirmatory factor analyses to test and compare the latent structures of the BPM-Y and BPM-P. Results suggested that the three-factor model of the BPM-Y and BPM-P fit the data best. And based on the omnibus fit indices and difference between them, the items of the BPM-Y and BPM-P support measurement invariance across informants (both youth- and parent-report) for the three-factor model. Internal consistency coefficients were satisfactory (Cronbach's α?=?.73?~?.90). In terms of convergent validity, BPM factors and BPM scores showed expected correlations with strength and difficulties behavior, callous–unemotional traits, psychopathic traits, and social competence. In sum, our findings supported that the three-factor structuure of BPM-Y and BPM-P could be a promising instrument to screen emotional and behavioral problems in Chinese youth.
