Topic: vestibular stimulation

Time perception can be distorted by factors such as arousal, attention or emotions. Recently, it has been demonstrated that stimulation of the vestibular system causes a contraction of subjective time (1). Conversely, the greater the amplitude of a whole-body rotation, the longer it seems to last, i.e. it causes a dilation of subjective time (2).To resolve this apparent inconsistency, and to better understand mechanisms of time perception during whole-body rotations, we evaluated time reproduction (2 or 4 seconds) in static (shakes) vs. two rotatory conditions (40° and 80°).The perceived time
