“…In corroboration of previous research that showed that increased action complexity (Sevdalis & Keller, 2009) and increased availability of information (Sevdalis & Keller, 2010) enhances agent identity perception, the current research shows that the process of inferring the actions and intentions of others relies on dynamic information about human movement, such as expression intensity and duration. Higher dynamic action range parameters can boost resonance in the observer's motor system, and, therefore, lead to enhanced sensitivity to small differences between kinematic patterns specifying underlying stimulus properties (Loula et al, 2005;Sevdalis & Keller, 2009.…”

This study investigated agent and expression intensity recognition in point-light displays depicting dancing performances. In a first session, participants danced with two different expression intensities to music, solo or in dyads. In a subsequent session, they watched point-light displays of 1-5-s duration, depicting their own, their partner's or another participant's recorded actions, and were asked to identify the agent (self vs. partner vs. stranger) and the intended expression intensity (expressive vs. inexpressive) of the performer. The results indicate that performer identity and expression intensity could be discerned reliably from displays as short as 1 s. The accuracy in judgment increased with exposure duration and, for performer identification, with higher expression intensity. Judgment accuracy in agent and expression intensity recognition tasks correlated with self-report empathy indices. Accuracy correlated also with confidence in judgment, but only in the intensity recognition task. The results are discussed in relation to perceptual and neural mechanisms underlying action and intention recognition.

“…The artificial tempo imposed by a treadmill reduces natural variation in the temporal properties that define an individual's gait. Similarly, the importance of temporal cues is suggested by studies showing that participants can recognize their own clapping both from degraded visual stimuli depicting just two point-lights [28] and from simple auditory tones matched with the temporal structure of actions [29].…”

Self-recognition of avatar motion: how do I know it's me?

When motion is isolated from form cues and viewed from third-person perspectives, individuals are able to recognize their own whole body movements better than those of friends. Because we rarely see our own bodies in motion from third-person viewpoints, this self-recognition advantage may indicate a contribution to perception from the motor system. Our first experiment provides evidence that recognition of self-produced and friends' motion dissociate, with only the latter showing sensitivity to orientation. Through the use of selectively disrupted avatar motion, our second experiment shows that selfrecognition of facial motion is mediated by knowledge of the local temporal characteristics of one's own actions. Specifically, inverted self-recognition was unaffected by disruption of feature configurations and trajectories, but eliminated by temporal distortion. While actors lack third-person visual experience of their actions, they have a lifetime of proprioceptive, somatosensory, vestibular and first-person-visual experience. These sources of contingent feedback may provide actors with knowledge about the temporal properties of their actions, potentially supporting recognition of characteristic rhythmic variation when viewing self-produced motion. In contrast, the ability to recognize the motion signatures of familiar others may be dependent on configural topographic cues.

“…Yet, perception in a complex sports situation never relies on only one sense. For instance, other studies have analyzed the relation between the auditory and visual senses (Thomas & Shiffrar, 2010;Sevdalis & Keller, 2010). This was examined by presenting point-light displays with added auditory information.…”
