面孔情绪下3～8岁儿童时距知觉的实验研究

新近研究结合日趋成熟的标量计时模型及神经学相关依据提出,情绪诱发的生理唤醒会加长主观时距,而注意唤醒会缩短主观时距,且各自有不同的发生特点。本研究选取3、5、8岁被试,系统探讨了800～3200ms范围内,儿童在高兴和生气两种面孔表情刺激下的时距知觉特点,并以中性面孔表情作为参照。研究发现:(1)3～8岁儿童都已具备明显的时距知觉,但时间敏感度随年龄的增加而提高;(2)3～8岁儿童时距判断均会受到情绪的干扰,情绪刺激下的主观时距长于中性刺激下的主观时距;(3)3～8岁儿童生气表情下的主观时距长于高兴表情下的主观时距,生理唤醒效应作用更为明显。     

面孔吸引力的回顾与前瞻

面孔吸引力是传递社会情感性信息的重要来源。面孔的平均化、对称性、性别二态性特征等因素会影响对面孔吸引力的评价。近年来, 研究者对面孔吸引力的研究已拓展到动态面孔上, 并采用fMRI技术发现当让被试评价有吸引力的面孔时, 杏仁核、眶额叶、腹侧枕叶等脑区被激活。研究者从进化论取向与认知取向两方面来解释人们为何偏好有吸引力的面孔。以往研究在研究内容、研究材料和研究对象等方面尚存不足, 这正是今后的研究方向。     

视觉与听觉情绪信息关系判断中的交互作用

通过要求被试判断同时呈现的视听信息情绪效价的关系,考察视听情绪信息整合加工特点。实验一中词汇效价与韵律效价不冲突,实验二中词汇效价与韵律效价冲突。两个实验一致发现当面孔表情为积极时,被试对视听通道情绪信息关系判断更准确;实验二还发现,当面孔表情为消极时,相对于韵律线索,被试根据语义线索对视听信息关系判断更迅速。上述结果说明视听信息在同时呈现时,视觉信息可能先行加工,并影响到随后有关视听关系的加工。     

情绪识别研究中被“冷落”的线索:躯体表情加工的特点、神经基础及加工机制

躯体和面孔是个体情绪表达与识别的重要线索。与面部表情相比,躯体表情加工的显著特点是补偿情绪信息,感知运动与行为信息,及产生适应性行为。情绪躯体与面孔加工的神经基础可能相邻或部分重合,但也存在分离;EBA、FBA、SPL、IPL等是与躯体表情加工相关的特异性脑区。今后应系统研究面孔、躯体及语音情绪线索加工潜在的神经基础,探讨躯体情绪加工的跨文化差异,考察情绪障碍患者的躯体表情加工特点。     

Organizational and client commitment among contracted employees

This study examines affective commitment to employing and client organizations among long-term contracted employees, a new and growing employment classification. Drawing on organizational commitment and social exchange literatures, we propose two categories of antecedents of employee commitment to client organizations. We tested our hypotheses using a survey collected from employees in four UK contracting organizations delivering a service on behalf of a government entity. The results suggest that perceived client organizational support and attractiveness of the client organization relate positively to employees’ affective commitment to the client organization. Furthermore, affective contractor commitment explained unique variation in client affective commitment beyond that accounted for by the client-based predictors, suggesting that employees’ commitment to their own contracting organization is important to explaining employees’ commitment to the client organization. We suggest that a greater reliance on social exchange theory may provide a basis for understanding commitment in its different forms and foci.     

No experimental evidence for emotion-specific gaze cueing in a threat context

We examined the utility of a gaze cueing paradigm to examine sensitivity to differences among negatively valenced expressions. Participants judged target stimuli (dangerous or safe), the location of which was cued by the gaze direction of a central face. Dawel et al. reported that gaze cueing effects (faster response times on valid vs. invalid trials) were larger when the central face displayed fear than when it displayed happiness. Our aim was to determine whether this effect was specific to fear, to all threat-related expressions (fear, anger), or to all negatively valenced expressions (fear, anger, sadness, disgust) with the aim of using this protocol to study the development of implicit discrimination of negatively valenced expressions. Across five experiments in which we varied the number of models (1 vs. 4), the number of expressions (2 vs. 5), and the country of residence of participants (Canada vs. Australia) we found no evidence that the magnitude of gaze cueing effects is modulated by expression. We discuss our failure to replicate in the context of the broader literature.     

Perceptual learning and recognition confusion reveal the underlying relationships among the six basic emotions

The six basic emotions (disgust, anger, fear, happiness, sadness, and surprise) have long been considered discrete categories that serve as the primary units of the emotion system. Yet recent evidence indicated underlying connections among them. Here we tested the underlying relationships among the six basic emotions using a perceptual learning procedure. This technique has the potential of causally changing participants’ emotion detection ability. We found that training on detecting a facial expression improved the performance not only on the trained expression but also on other expressions. Such a transfer effect was consistently demonstrated between disgust and anger detection as well as between fear and surprise detection in two experiments (Experiment 1A, n?=?70; Experiment 1B, n?=?42). Notably, training on any of the six emotions could improve happiness detection, while sadness detection could only be improved by training on sadness itself, suggesting the uniqueness of happiness and sadness. In an emotion recognition test using a large sample of Chinese participants (n?=?1748), the confusion between disgust and anger as well as between fear and surprise was further confirmed. Taken together, our study demonstrates that the “basic” emotions share some common psychological components, which might be the more basic units of the emotion system.     

Foreign and domestic company attractiveness to host national employees in Japan: A person–organization fit and image theory perspective

This study contributes to research on organizational attractiveness and human resource management (HRM) by drawing on image theory to examine the effect of organizational characteristics (foreign vs. domestic company country‐of‐origin, HRM practices, organizational culture, and work environment) on organizational attractiveness perceptions by host country national (HCN) employees. Drawing on person–organization fit theory, we also examine the moderating effects of HCNs' demographic characters (age and gender), work‐related skills (English proficiency and international experience), and value orientations (individualism and risk aversion) between the relationship of these organizational characteristics and organizational attractiveness. A between‐subject scenario‐based experiment with 800 HCN employees in Japan suggest that not the company country‐of‐origin, but the local adaptation of organizational culture, HRM practices, and work environment influence HCNs' organizational attractiveness perceptions. HCNs' demographic characteristics, work‐related skills, and value orientations had moderating effects between these organizational characteristics and organizational attractiveness perceptions.     

Neural correlates of facial emotion processing in infancy

In the present study we examined the neural correlates of facial emotion processing in the first year of life using ERP measures and cortical source analysis. EEG data were collected cross‐sectionally from 5‐ (N = 49), 7‐ (N = 50), and 12‐month‐old (N = 51) infants while they were viewing images of angry, fearful, and happy faces. The N290 component was found to be larger in amplitude in response to fearful and happy than angry faces in all posterior clusters and showed largest response to fear than the other two emotions only over the right occipital area. The P400 and Nc components were found to be larger in amplitude in response to angry than happy and fearful faces over central and frontal scalp. Cortical source analysis of the N290 component revealed greater cortical activation in the right fusiform face area in response to fearful faces. This effect started to emerge at 5 months and became well established at 7 months, but it disappeared at 12 months. The P400 and Nc components were primarily localized to the PCC/Precuneus where heightened responses to angry faces were observed. The current results suggest the detection of a fearful face in infants’ brain can happen shortly (~200–290 ms) after the stimulus onset, and this process may rely on the face network and develop substantially between 5 to 7 months of age. The current findings also suggest the differential processing of angry faces occurred later in the P400/Nc time window, which recruits the PCC/Precuneus and is associated with the allocation of infants’ attention.     

美的就是好的?外貌吸引力在亲密关系中的作用

外貌吸引力对亲密关系的建立和发展发挥着不可忽视的作用。由于高外貌吸引力个体被认为具有更多的社会理想特质和更优良的基因, 因此被视为具有更高的配偶价值, 从而有效地促进亲密关系的建立。然而在亲密关系发展中, 由于不匹配的外貌吸引力引起低外貌吸引力伴侣采取一系列的伴侣保留、嫉妒、侮辱和性强迫行为, 从而加速亲密关系的破裂。也有研究指出高外貌吸引力男性可能不具有良好的基因, 而女性也不会在繁殖高峰期偏爱高外貌吸引力男性。“美的就是好的”的看法正在受到质疑, 研究结果也已引发了诸多争议和分歧, 相关的直接证据亦有待进一步夯实。
