Document Summary
A neural process by which you enhance your perception of certain stimuli relative to other stimuli in the environment. Bottom- up attention- the object grabs your attention without conscious knowledge of the stimulus. The stimulus is more salient than the background, they activate the v1. Top down attention: you consciously look for a specific object, active attention, focused to a specific location. Change blindness: visual transients are not put in visual memory to identify what changed (the capacity is very small) Damage to the right parietal lobe: disrupts visual attention to the left side of the visual space- neglect syndrome. Attention reduces detection of stimuli away from site of attention. Right parietal lobe might be involved in disengaging visual attention. 5 types of eye movements: saccadic eye movements- conjugate vestibular eye movements- vestibulo- ocular reflecx (vor)- conjugate. ********eye movements have two goals: redirect line of sight and maintain image stability (eliminate retinal slip)
