Sensory Analysis

Our cognition processes information coming from different channels of sensory modalities and integrates it smoothly. In most of the time we are not even aware of the modalities of the information, rather all we are conscious of is the information itself. Having more senses provides more accuracy in different dimensions of an event such as time and space. For example, one sense is less accurate about carrying time dimension of an event, while other is less accurate about estimating the location. Altogether multiple channels provide better accuracy of perception. It was long time ago that multi-sensory stimuli provided faster reaction compare to unisensory (Hershenson, 1962). Timing of an event in our perception is mostly driven by audition in such a way that, for instance, rate of the auditory stimuli, flutters, affects the perceived rate of visual flickers more than flickers affect perceived rate of flutters (Gebhard & Mowbray, 1959; R. B. Welch, DutionHurt, & Warren, 1986). Likewise, auditory click can change timing of visual stimuli, which is known as temporal ventriloquism (Fendrich & Corballis, 2001; Morein-Zamir, Soto-Faraco, & Kingstone, 2003; Recanzone, 2003). On the other hand, visual stimuli can affect the perception of the sound location (Alais & Burr, 2004; Bertelson & Aschersleben, 1998; Howard & Templeton, 1966). …show more content…
Welch & Warren, 1980), since each sense drives others in the dimension for which they are designed. Neural mechanisms of multisensory integration have been investigated in many recent studies. Specifically, auditory effects in the visual cortex have been showed in many EEG studies in different methods of analyses (Busch, Wilson, Orr, & Papanicolaou, 1989). [Some others, Naue et al., Phase
