情绪生理机制研究的外周与中枢神经系统整合模型

阐明人类情绪的生理机制是心理学家和神经科学家所面临的巨大挑战。以往研究倾向于分别考察情绪的外周反应模式和脑机制。近年来,随着情绪电生理学和认知神经科学的发展,许多研究者从外周与中枢神经系统相互作用的角度,提出了一些解释情绪生理机制的整合模型。其中,以情绪环路模型和神经内脏整合模型为典型代表。前者强调由外周到中枢的自下而上的加工方式,试图说明情绪经验形成的机制;后者则采取由中枢到外周的自上而下的加工方式,试图阐明情绪调控的机制。今后的研究有必要借鉴这两个模型,并结合近期有关情绪信息加工神经机制的新成果,以便构建能够更为全面解释人类情绪的生理模型。     

Work-family balance and energy: A day-level study on recovery conditions

The present study examines whether daily recovery inhibiting and enhancing conditions predict day-levels of work-family conflict (WFC), work-family facilitation (WFF), exhaustion and vigor. Forty-nine individuals from various professional backgrounds in Spain provided questionnaire and daily survey measures over a period of five working days. Multilevel analyses showed that day-levels of work pressure and recovery after breaks at work significantly predicted WFC and exhaustion, and WFF and vigor, respectively. Moreover, daily fluctuations in expression of emotions had different effects depending on the expressed content (negative or positive) and the setting where it took place (work or home). Furthermore, additional analyses provided some evidence for a moderating role of expression of emotions at work on the relationship between recovery inhibiting and enhancing conditions and exhaustion. These findings reveal practical implications for individuals and organizations and suggest possible avenues for future research.     

Can bottom-up processes of attention be a source of ‘interference’ in situations where top-down control of attention is crucial?

In this study, we investigate whether emotionally engaged bottom-up processes of attention can be a source of ‘interference’ in situations where top-down control of attention is necessary. Participants were asked to monitor and report on a video of a war scenario showing a developing battle in two conditions: emotionally positive and emotionally negative. Half of the participants (n = 15) were exposed to task-irrelevant pictures of positive emotional valence embedded within the scenario; the other half were exposed to task-irrelevant pictures of negative emotional valence. Sensitivity and Bias scores were calculated using signal detection theory. Overall, task accuracy scores were dependent upon the valence; negative pictures had an adverse effect on performance, whereas positive pictures improved performance. We concluded that negative emotional pictures interfered with top-down control of attention by attracting competing bottom-up processes of attention. We found the opposite effect for positive emotional stimuli.     

Mothers' Ideal Positive Affect Predicts their Socialization of Children's Positive Affect

Parents generally want their children to be happy, but little is known about particular types of positive affect (PA) that parents want their children to experience. Tsai's (2007) affect valuation theory offers a useful framework to understand how parents' emotional goals may shape the socialization of particular types of PA (e.g., excitement vs. relaxation). Participants were 96 mothers and their 7- to 12-year-old children. Results indicated that mothers endorsed similar levels of ideal PA (IPA) for low-, moderate-, and high-arousal PA for both themselves and for their child, suggesting that mothers desire the same type of PA for their children as they want for themselves. In support of the study's main hypothesis, mothers' IPA for their children predicted specific socialization responses that would encourage that type of PA (e.g., mothers' high-arousal IPA predicted greater encouragement of their child to celebrate, whereas mothers' low-arousal IPA predicted encouragement of affection). The findings extend affect valuation theory and emotion socialization research by indicating that parents' emotional goals (i.e., IPA) for their children may contribute to their socialization of children's PA.     

Exploring and integrating discrete and dimensional approaches while inducing negative emotional states

Selecting visual stimuli for inducing specific emotional states is very challenging, since the choice relies on specific conceptualization of emotions. In this work, we present a set of 55 stimuli, realized integrating discrete and dimensional theories of emotions, and specifically selected to investigate anger, fear, and disgust reactions in non-clinical and clinical contexts. Our set of stimuli presents several aspects of novelty since (1) a large and heterogeneous sample of subjects from the general population was involved in the labelling task, and (2) bivariate and multivariate statistical techniques were applied to integrate emotion models. The proposed set of stimuli could be useful for researchers and other professionals in the affective sciences to address negative emotion recognition issues within a broader perspective both in general population and in psychiatric samples. The obtained comprehensive characterization of the stimuli allowed us to confirm the sexual dimorphism in emotional processing.     

An Exploration of Some Antecedents and Consequences of Creative Self‐Efficacy among College Students

Two studies examined the role of task‐, self‐, and other‐approach achievement goals, trait curiosity, and enjoyment as antecedents of creative self‐efficacy and the influence of creative self‐efficacy on grade point average and perceived performance/effort exerted among college business students from Mexico. To test our research hypotheses, we used Structural Equation Modeling treating the variables as latent. Results from study 1 showed that task/self‐approach goal was a significant antecedent of creative self‐efficacy and enjoyment a marginally significant antecedent. Results from study 2 showed a positive, significant influence of trait curiosity on creative self‐efficacy. Similarly, creative self‐efficacy had a positive, direct influence on perceived performance/effort exerted and an indirect influence on students' grade point average. The implications of our results were discussed.     

Explaining embodied emotions – with and without representations

Embodied accounts have offered a theoretical framework in which emotions are understood to be patterned embodied responses that are about core relational themes. Some authors argue that this intentionality should be understood in terms of some kind of non-conceptual representation format, while others suggest a radical enactivist framework that takes emotions to be intentional but not representational. In this paper I will argue that the abstract nature of the core relational themes emotions are about and the interrelatedness of emotions with each other and with other mental states speak in favor of emotions being representations.     

Not quite neo-sentimentalism

The view that some evaluative concepts are identical to some affective concepts naturally falls out of neo-sentimentalism, but it is unstable. This paper argues for a view of evaluative concepts that is neo-sentimentalist in spirit but which eschews the identity claim. If we adopt a Peacockean view of concepts, then we should think of some evaluative concepts as having possession conditions that are affective in some way. I argue that the best version of this thought claims that possessing those concepts requires being rationally compelled to form evaluative beliefs in response to certain emotions.
