Crossmodal emotional modulation of time perception
b'The thesis that consists of three studies investigated how visual affective stimuli or action as contexts influence crossmodal time processing, particularly on the role of the crossmodal/sensorimotor linkage in time perception. By using different types of emotional stimuli (e.g., threat, disgust, and neutral pictures) and manipulating the possibility of near-body interactions, three studies disassociated the impacts of embodied action from emotional dimensions (arousal and valence) on crossmodal emotional modulation in time perception. The whole thesis thus offered the first behavioral evidence that embodied action is an important factor that expands subjective tactile duration and facilitates tactile selection (modality-specific temporal processing) in emotion and action contexts. Moreover, subjective expansion of duration by threat and action contexts may reflect the evolutionary coupling of our perceptual and motor systems to adapt to the specific environments for survival and success.'
