Spatiotemporal aspects in audiovisual interaction

摘要: How humans perceive everyday reality is one of the most fascinating and enduring interest different scientific disciplines. The aim present dissertation to investigate - from both a theoretical an empirical perspective some aspects concerning crossmodal interactions between hearing vision. In first part introduction special attention given cortical subcortical neural substrate involved in integrating sensory modalities, more specifically, audiovisual stimuli. Experimental studies literature designed empirically interaction potential existence dominance vision will be presented. last part, focalized discuss principal models aimed predict outcome integration its relation with dominance. The following chapters experimental role eye movements auditory cognition. In study, effects on spatial representation explored. disentangle controversial results emerged two that used type sounds (i.e., free field provided through loudspeakers vs. intracranially headphones) tasks. In second disputed perception action investigated presence illusion. verify whether participants’ visuo-motor behaviour might biased by visual illusion as for perception, eventually, perceptive motor biases are correlated. The study presented this explore stimulation low patients pathology. More precisely, possible detection enhancement sound coupled stimulus investigated. To purpose, experiment, effect disparity stimuli deepened while experiments temporal disparities stimuli. The described provide evidence cognition systems induced sound. Moreover findings report time significant audition patients.
