Being active over one's own motion: Considering predictive mechanisms in self-motion perception. (March 2023) - Rineau, Anne-Laure
Abstract: Self-motion perception is a key element guiding pilots' behavior. Its importance is mostly revealed when impaired, leading in most cases to spatial disorientation which is still today a major factor of accidents occurrence. Self-motion perception is known as mainly based on visuo-vestibular integration and can be modulated by the physical properties of the environment with which humans interact. For instance, several studies have shown that the respective weight of visual and vestibular information depends on their reliability. More recently, it has been suggested that the internal state of an operator can also modulate multisensory integration. Interestingly, the systems' automation can interfere with this internal state through the loss of the intentional nature of movements (i.e., loss of agency) and the modulation of associated predictive mechanisms. In this context, one of the new challenges is to better understand the relationship between automation and self-motion perception. The present review explains how linking the concepts of agency and self-motion is a first approach to address this issue. Highlights: The need for an active approach to human perception is increasingly stressed. The impact of action control on visual-vestibular integration remains unexplored. The active sensing issue can be addressed through the concept of agency. The predictive mechanisms involved in agentive situations are likely to impact the mechanisms of multi-sensory integration. The links between prediction, action control and perception could have a dramatic impact on operational performance, particularly through the phenomenon of spatial disorientation.
