All our perceptions derive from our senses. Reaction and learning require sensory input.
Philosophers like Aristotle have concluded there would be no mental life without sensation;
what would you be able to think about with no knowledge gained from senses?
Sensory systems have evolved in all animals for the purpose of guiding their
behaviour. To survive and reproduce, they must react to the world in which they live. Sensory
systems did not evolve to provide full, objective accounts of the world’s physical properties.
Rather, they evolved to provide specific kinds of information to the animal to help it survive
and reproduce.
Sensation refers to the basic processes by which sensory organs and the nervous
system respond to stimuli in the environment and to the elementary physiological
experiences that result from those processes (e.g. bitterness of a taste, loudness of sound).
Perception refers to the more complex organising of sensory information within the
brain and to the meaningful interpretations extracted from it (e.g. my alarm clock is ringing,
that object is an apple).
The study of perception is more closely tied to the study of thought and memory than
is the study of sensation. The distinction is fuzzy because the organising of stimulus
information in ways useful for extracting meaning actually begins during the earliest steps in
taking that information in.
1. Overview of sensory processes
Q: how can the process of sensation be described as a chain of three different kinds of
events?
Physical stimulus → physiological response → sensory experience
(1) The physical stimulus is the matter of energy of the physical world that impinges on
sense organs; (2) the physiological response is the pattern of chemical and electrical
activity that occurs in sense organs, nerves, and the brain as a result of the stimulus; and (3)
