A key feature of facial behavior is its dynamic quality. However, most previous research has been limited to the use of static images of prototypical expressive patterns. This article explores the role of facial dynamics in the perception of emotions, reviewing relevant empirical evidence demonstrating that dynamic information improves coherence in the identification of affect (particularly for degraded and subtle stimuli), leads to higher emotion judgments (i.e., intensity and arousal), and helps to differentiate between genuine and fake expressions. The findings (...) underline that using static expressions not only poses problems of ecological validity, but also limits our understanding of what facial activity does. Implications for future research on facial activity, particularly for social neuroscience and affective computing, are discussed. (shrink)

This paper selectively reviews the neurophysiological evidence for shared neural circuits (supposedly implemented by mirror neurons) as the mechanism underlying empathy. I will argue that while the mirror neuron system plays a role in motor resonance, it is not possible to conclude that this system is critically involved in emotion recognition, and there is little evidence for its role in empathy and sympathy. In addition, there is modest support from neurological observations that lesion of the regions involved in the mirror (...) neuron system leads to dysfunction in empathy, whereas damage of the ventromedial prefrontal cortex is associated with such impairment. To significantly advance our understanding of the mechanisms underlying empathy, research needs finer conceptualization, better designed paradigms, and integration with knowledge from lesion studies.
