Production of facial expressions of emotion in preschool children.

138 preschool children created faces with manipulable facial components to represent expressed emotions. Proportions selecting appropriate components varied with emotions so the task was perhaps more cognitively demanding than Ekman and Friesen's facial recognition task.

Experiencing positive affect and negative affect during stress: relationships to cardiac reactivity and to facial expressions.

We examined the relationship between experienced positive/negative affect and cardiac reactivity and facial muscle movements during laboratory tasks with different demands. Heart rate, respiratory sinus arrhythmia, pre-ejection period, and facial electromyography were measured during startle, mental arithmetic, reaction time task, and speech task. The results revealed that individuals experiencing high levels of positive affect exhibited more pronounced parasympathetic, heart rate, and orbicularis oculi reactivity than others. Individuals who experienced high levels of negative affects during the tasks showed higher corrugator supercilii responses. Men and women showed slightly different response patterns. To conclude, cardiac reactivity may be associated with positive involvement and enthusiasm in some situations and all reactivity should not automatically be considered as potentially pathological.

Production of emotional facial expressions in European American, Japanese, and Chinese infants.

European American, Japanese, and Chinese 11-month-olds participated in emotion-inducing laboratory procedures. Facial responses were scored with BabyFACS, an anatomically based coding system. Overall, Chinese infants were less expressive than European American and Japanese infants. On measures of smiling and crying, Chinese infants scored lower than European American infants, whereas Japanese infants were similar to the European American infants or fell between the two other groups. Results suggest that differences in expressivity between European American and Chinese infants are more robust than those between European American and Japanese infants and that Chinese and Japanese infants can differ significantly. Cross-cultural differences were also found for some specific brow, cheek, and midface facial actions (e.g., brows lowered). These are discussed in terms of current controversies about infant affective facial expressions.

Laterality for facial expressions: does the sex of the subject interact with the sex of the stimulus face?

Seventy right-handed subjects (35 males and 35 females) were shown lateralized pictures of negative, neutral, and positive facial emotional expressions. For each emotional category, half of the pictures were of a male face showing the emotion, half were of a female face. The pictures were shown in the left visual half-field for half of the trials and in the right half-field for the other half of the trials. The question addressed was whether the sex of the stimulus face interacts with the sex of the subject for hemisphere differences in perception of facial emotions. Response accuracy and reaction time were measured. The pictures were shown from a slide projector with a high-speed shutter mounted to the lens to allow for tachistoscopic presentations. The results showed that the right hemisphere was more accurate and faster than the left in recognizing the stimulus faces, and that positive emotions were overall more easily recognized. The lack of a significant interaction between sex of the stimulus and sex of the subject indicates that these two factors are not interrelated or confounded in laterality research.
