Autonomic nervous system activity in emotion: A review

This paper examines the literature on computer games and serious games in regard to the potential positive impacts of gaming on users aged 14 years or above, especially with respect to learning, skill enhancement and engagement. Search terms identified 129 papers reporting empirical evidence about the impacts and outcomes of computer games and serious games with respect to learning and engagement and a multidimensional approach to categorizing games was developed. The findings revealed that playing computer games is linked to a range of perceptual, cognitive, behavioural, affective and motivational impacts and outcomes. The most frequently occurring outcomes and impacts were knowledge acquisition/content understanding and affective and motivational outcomes. The range of indicators and measures used in the included papers are discussed, together with methodological limitations and recommendations for further work in this area.

Automatic facial expression analysis: a survey

Synthetic images of facial expression were used to assess whether judges can correctly recognize emotions exclusively on the basis of configurations of facial muscle movements. A first study showed that static, synthetic images modeled after a series of photographs that are widely used in facial expression research yielded recognition rates and confusion patterns comparable to posed photos. In a second study, animated synthetic images were used to examine whether schematic facial expressions consisting entirely of theoretically postulated facial muscle configurations can be correctly recognized. Recognition rates for the synthetic expressions were far above chance, and the confusion patterns were comparable to those obtained with posed photos. In addition, the effect of static versus dynamic presentation of the expressions was studied. Dynamic presentation increased overall recognition accuracy and reduced confusions between unrelated emotions.

Studying the dynamics of emotional expression using synthesized facial muscle movements.

Appraisal theorists suggest that the face expresses cognitive processes involved both in the orienting of attention (primarily gaze direction) and in the evaluation of emotion-eliciting events. Contrary to the assumption of direct emotion recognition by basic emotions theorists, this implies an interaction effect between “perceived gaze direction” and “perceived facial expression” in inferring emotion from the face. These two theoretical perspectives were comparatively tested by requesting participants to decode dynamic synthetic facial expressions of emotion presented with either an averted or a direct gaze. Confirming the interaction predicted by appraisal theories, the perceived specificity and intensity of fear and anger depended on gaze direction (direct gaze for anger and averted gaze for fear).

Interaction effects of perceived gaze direction and dynamic facial expression: Evidence for appraisal theories of emotion

A computer game was used to study psychophysiological reactions to emotion-relevant events. Two dimensions proposed by Scherer (1984a, 1984b) in his appraisal theory, the intrinsic pleasantness and goal conduciveness of game events, were studied in a factorial design. The relative level at which a player performed at the moment of an event was also taken into account. A total of 33 participants played the game while cardiac activity, skin conductance, skin temperature, and muscle activity as well as emotion self-reports were assessed. The self-reports indicate that game events altered levels of pride, joy, anger, and surprise. Goal conduciveness had little effect on muscle activity but was associated with significant autonomic effects, including changes to interbeat interval, pulse transit time, skin conductance, and finger temperature. The manipulation of intrinsic pleasantness had little impact on physiological responses. The results show the utility of attempting to manipulate emotion-constituent appraisals and measure their peripheral physiological signatures.

Psychophysiological responses to appraisal dimensions in a computer game

Facial expressions as indicators of appraisal processes.

A method was developed for automated coding of facial behavior in computer-aided test or game situations. Facial behavior is registered automatically with the aid of small plastic dots which are affixed to pre-defined regions of the subject's face. During a task, the subject's face is videotaped, and the picture is digitized. A special pattern-recognition algorithm identifies the dot pattern, and an artificial neural network classifies the dot pattern according to the Facial Action Coding System (FACS; Ekman & Friesen, 1978). The method was tested in coding the posed facial expressions of three subjects, themselves FACS experts. Results show that it is possible to identify and differentiate facial expressions by their corresponding dot patterns. The method is independent of individual differences in physiognorny.
