It is an example of how perception can be shaped by "top-down" processes such as drives and expectations. [106] Perceptual sets occur in all the different senses. [62] 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 ...
Perceptual learning is a more in-depth relationship between experience and perception. Different perceptions of the same sensory input may arise in individuals with different experiences or training. This leads to important issues about the ontology of sensory experience, the relationship between cognition and perception. An example of this is ...
Sperry argued that the perception–action cycle is the fundamental logic of the nervous system. [2] Perception and action processes are functionally intertwined: perception is a means to action and action is a means to perception. Indeed, the vertebrate brain has evolved for governing motor activity with the basic function to transform sensory ...
A context effect is an aspect of cognitive psychology that describes the influence of environmental factors on one's perception of a stimulus. [1] The impact of context effects is considered to be part of top-down design. The concept is supported by the theoretical approach to perception known as constructive perception. Context effects can ...
Perceptual narrowing is a developmental process during which the brain uses environmental experiences to shape perceptual abilities. This process improves the perception of things that people experience often and causes them to experience a decline in the ability to perceive some things to which they are not often exposed.
The term originates with René Descartes in the form of the word apercevoir in his book Traité des passions. Leibniz introduced the concept of apperception into the more technical philosophical tradition, in his work Principes de la nature fondés en raison et de la grâce; although he used the word practically in the sense of the modern attention, by which an object is apprehended as "not ...
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
Constructive perception is the theory of perception in which the perceiver uses sensory information and other sources of information to construct a cognitive understanding of a stimulus. In contrast to this top-down approach, there is the bottom-up approach of direct perception. Perception is more of a hypothesis, and the evidence to support ...
