Study
Perception and Attention
The studies about perception and attention involve different types of stimulation, which may be hearing, visual, tactile, olfactory, gustatory, proprioceptive, cognitive, somesthetic, visceral, autonomous or gravitational.
The basic or applied research can investigate the effects of the allocation of attention in the visual field, the role of shape and color in selective visual processing, the tonotopic location or laterality in the ears, the interference in serial verbal reactions, among other topics.
