1. Introduction
Perceiving and interpreting the movements and actions of other individuals is an important aspect for human social interaction [1,2]. Thus, it is not surprising that humans are very accurate and efficient at recognizing other peoples’ movements or gestures. It has been demonstrated already more than 40 years ago that observers can easily recognize the actions of other individuals even if the to-be-observed human body is depicted by only a handful light dots on an otherwise invisible body [3]. The sparse information of these so-called point-light displays has been shown to be sufficient to recognize gender, identity, or mood of the actor [4–6].Despitemany years of research and increasing knowledge about the perception of human movements, the neuronal mechanisms are still not fully understood. While there is mounting evidence that the superior temporal sulcus (STS) and lateral occipito-temporal cortex (LOTC) are critically involved in the process of perceiving human movements [7,8], also other cortical areas have been shown to play a role for the perception of human movements. For example, areas of the motor system, which are typically involved in the execution of movements, have been associated also with movement perception [9][e.g. 9]. In this regard, theories have postulated a link between movement perception and execution of movements [10]. These theories have been supported by behavioral studies demonstrating interference between visual perception of a movement and the observer’s own movement or movement capabilities. For example, compared to stationary observers, walking observers were impaired in judging the walking speed of animated persons [11]. Similarly, it has been shown that self-generated movement of the observers modulates discrimination of body postures and movements [12,13]. Furthermore, observers’ ability to judge the weight of a box lifted by another person depends on the weight of a box lifted by the observers [14]. Further evidence for a link between movement perception and execution of actions comes from fMRI studies reporting BOLD responses in the (pre)motor system during action perception [9,15,16]. In addition, EEG and MEG studies reported a suppression of alpha/mu- and beta-activity (8–30 Hz) in sensors over central and motor areas during action observation and imagination [17–20]. This suppression of alpha/beta-band activity wasmodulatedbyplausibility andthe lateralizationofthe observed action [19,21,22].
