Does audience size influence actors' and spectators' emotions the same way?

Better understanding how audience size influences emotions and behaviours during public performances is of particular importance since it may both impact the level of anxiety and quality of achievement of the performer and alter the degree of appreciation of the observer. We tested this question in a naturalistic setting by analyzing self-assessment questionnaires, Galvanic skin responses and behaviours of actors and spectators during theatrical representations with small, medium and large audiences. We found that: actors and spectators differed in their perception of the effects of audience size; the different components of emotions (cognitive, physiological, behavioural) were affected differently by audience size, which was also modulated by the individual's status; actors and spectators differed in their representation of the others' emotional state. Although our study remains exploratory, our findings highlight the complexity of the audience effect when comparing observers' and performers' emotions.

Influence of theatre hall layout on actors' and spectators' emotions.

"Audience effect" is the influence of an audience size or composition on the emotional state of a public speaker. One characteristic of the audience which has received little attention is the spatial position of observers. We tested the influence of three positions (frontal, bi-frontal, and quadri-frontal) on actors and spectators' emotions in real theatrical representations. Measurements consisted in self-report questionnaires and galvanic skin responses. The layout of the theatre hall influenced both cognitive and physiological components of emotions. Actors were more influenced than spectators and showed an overall accuracy in self-perception. The quadri-frontal audience received the highest scores in actors' feeling assessments and galvanic skin responses. In addition, we found a discrepancy between self-assessment of emotional states by spectators and how actors perceive them. Attention should thus be paid in the layout of performance places with obviously more attention from the public and better feelings for actors in more dispersed settings.
