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.
