[9] [10] He was the first person to explain that vision occurs when light bounces on an object and then is directed to one's eyes. [11]
Direct realism, also known as naïve realism, argues we perceive the world directly. In the philosophy of perception and philosophy of mind, direct or naïve realism, as opposed to indirect or representational realism, are differing models that describe the nature of conscious experiences; [1] [2] out of the metaphysical question of whether the world we see around us is the real world itself ...
A perceptual set, also called perceptual expectancy, is a predisposition to perceive things in a certain way. [1] Perceptual sets occur in all the different senses. [2] They can be long term, such as a special sensitivity to hearing one's own name in a crowded room, or short term, as in the ease with which hungry people notice the smell of food ...
