Face aftereffects suggest interdependent processing of expression and sex and of expression and race

Bruce and Young (1986) proposed that functionally different aspects of faces (e.g., sex, identity, and expression) are processed independently. Although interdependent processing of identity and expression and of identity and sex have been demonstrated previously, evidence for interdependent processing of sex and expression is equivocal. Using a visual adaptation paradigm, we show that expression aftereffects can be simultaneously induced in different directions along anger–fear continua for male and female faces (Experiment 1) and for East Asian and Black African faces (Experiment 2). These findings for sex- and race-contingent expression aftereffects suggest that processing of expression is interdependent with processing of sex and race and are therefore problematic for models of face perception that have emphasized independent processing of functionally different aspects of faces. By contrast, our findings are consistent with models of face processing that propose that invariant physical aspects of faces and changeable social cues can be processed interdependently.     

The role of age on reactivity and memory for emotional pictures

The purpose of this study was to investigate subjects' reactivity to emotional pictures and their recollection of these pictures, and to examine these two factors as they relate to age. Adolescents and young adults were shown emotionally arousing scenic pictures for long (4-s) and very brief (50-ms) durations. Recognition of the pictures and recall and recognition of words presented along with the pictures were assessed both immediately after the presentation and six weeks later. The results showed that very negative pictures are retained better than neutral or even positive pictures, and that very negative pictures reduce memory for associated information. It was also found that adolescents show a somewhat lower reactivity to very negative pictures and a higher degree of retention of these pictures than adults. The results are discussed in relation to (a) habituation effects, (b) strategies that subjects might develop to block emotional involvement, and (c) the notion that watching violence might serve as a powerful prime to socially undesirable behaviour.     

Emotional valence of spoken words influences the spatial orienting of attention

The influence of the affective content of speech on the spatial orienting of auditory attention was examined by adapting the dot probe task. Two words, one of which was emotional in one quarter of the trials, were played simultaneously from a left- and a right-located loudspeaker, respectively, and followed (or not) by a lateralized beep to be detected (Experiments 1 and 2) or localized (Experiment 3). Taboo words induced attentional biases towards their spatial location in all experiments, as did negative words in Experiment 3, but not positive words. Thus, in audition, the identification of an emotional word automatically activates the information about its spatial origin. Moreover, for both word types, attentional biases were only observed when the emotional word was presented on the participant's right side, suggesting that the dominant left hemisphere processing of words constrains the occurrence of spatial congruency effects.     

Preschoolers’ appreciation of speaker vocal affect as a cue to referential intent

An eye tracking methodology was used to evaluate 3- and 4-year-old children’s sensitivity to speaker affect when resolving referential ambiguity. Children were presented with pictures of three objects on a screen (including two referents of the same kind, e.g., an intact doll and a broken doll, and one distracter item), paired with a prerecorded referentially ambiguous instruction (e.g., “Look at the doll”). The intonation of the instruction varied in terms of the speaker’s vocal affect: positive-sounding, negative-sounding, or neutral. Analyses of eye gaze patterns indicated that 4-year-olds, but not 3-year-olds, were more likely to look to the referent whose state matched the speaker’s vocal affect as the noun was heard (e.g., looked more often to the broken doll referent in the negative affect condition). These findings indicate that 4-year-olds can use speaker affect to help identify referential mappings during on-line comprehension.     

Emotional intelligence, personality and the decoding of non-verbal expressions of emotion

Previous research has highlighted theoretical and empirical links between measures of both personality and trait emotional intelligence (EI), and the ability to decode facial expressions of emotion. Research has also found that the posed, static characteristics of the photographic stimuli used to explore these links affects the decoding process and differentiates them from the natural expressions they represent. This undermines the ecological validity of established trait-emotion decoding relationships.This study addresses these methodological shortcomings by testing relationships between the reliability of participant ratings of dynamic, spontaneously elicited expressions of emotion with personality and trait EI. Fifty participants completed personality and self-report EI questionnaires, and used a computer-logging program to continuously rate change in emotional intensity expressed in video clips. Each clip was rated twice to obtain an intra-rater reliability score. The results provide limited support for links between both trait EI and personality variables and how reliably we decode natural expressions of emotion. Limitations and future directions are discussed.     

问题类型和情绪状态对贝叶斯推理的影响

本研究以240名大学生为被试,探讨了问题类型和情绪状态对贝叶斯推理的影响。结果表明：(1)问题类型对贝叶斯推理有影响;(2)情绪状态对贝叶斯推理有影响;(3)问题类型与情绪状态对贝叶斯推理的影响存在交互作用。具体地,在经典乳癌问题中,被试在消极情绪状态下比在积极情绪状态下做出更高的概率估计,而在中彩问题中,被试在积极情绪状态下比在消极情绪状态下概率估计更高。     

Emotional context, maternal behavior and emotion regulation

This study investigated the importance of emotion-eliciting context (positive and negative) and mother's behaviors (constrained and involved) on toddlers’ emotion regulation behavioral strategies, emotional expressiveness and intensity, during three episodes eliciting fear, frustration/anger and positive affect. Fifty-five children between 18 and 26 months of age and their mothers participated in the study. Toddlers’ regulatory strategies varied as function of emotion-eliciting context (children exhibited behavioral strategies more frequently during positive affect and frustration/anger episodes and less frequently during fear episodes) and maternal involvement. Toddlers’ expression of emotion varied as function of emotion-eliciting context (children exhibited more emotional expressions, both negative and positive during fear and frustration/anger episodes compared to positive affect episodes). Toddlers’ expression of emotion was not strongly related to maternal involvement, however, the intensity of emotional expression was related to the interaction of context and maternal involvement.     

Categorical perception along the happy–angry and happy–sad continua in the first year of life

The current study investigated 6-, 9- and 12-month old infants’ ability to categorically perceive facial emotional expressions depicting faces from two continua: happy–sad and happy–angry. In a between-subject design, infants were tested on their ability to discriminate faces that were between-category (across the category boundary) or within-category (within emotion category). Results suggest that 9- and 12 month-olds can discriminate between but not within categories, for the happy–angry continuum. Infants could not discriminate between cross-boundary facial expressions in the happy–sad continuum at any age. We suggest a functional account; categorical perception may develop in conjunction with the emotion's relevance to the infant.     

Emotional reactions to crime across cultures

Information about the emotions experienced by observers when they witness crimes would have important theoretical and practical implications, but to date no study has broadly assessed such emotional reactions. This study addressed this gap in the literature. Observers in seven countries viewed seven videos portraying actual crimes and rated their emotional reactions to each using 14 emotion scales. Observers reported significantly high levels of negative emotions including anger, contempt, disgust, fear and sadness‐related emotions, and anger, contempt and disgust were the most salient emotions experienced by viewers across all countries. Witnesses also reported significantly high levels of positive emotions as well (compared to not feeling the emotion at all), which was unexpected. Country moderated the emotion ratings; post‐hoc analyses indicated that masculine‐oriented cultures reported less nervousness, surprise, excitement, fear and embarrassment than feminine cultures.     

Fear and anxiety modulate mental rotation

We used an emotional priming paradigm to investigate whether fear and anxiety modulate mental rotation of abstract three-dimensional objects (i.e., Shepard-Metzler figures). On each trial, participants viewed pairs of objects and decided whether the objects had the identical shape by mentally rotating the one on the right into congruence with the one on the left. The participants viewed a picture of a face—fearful or neutral—briefly before the pairs of objects appeared. Participants with high state anxiety, and not those with low state anxiety, rotated the objects more quickly after they saw fearful faces than after they saw neutral faces. This result not only documents that fear can improve mental rotation but also shows that this effect is modulated by the emotional arousal of the participants.
