Perception: process by which the brain interprets the sensory information to make sense of the world. Transduction: process whereby the characteristics of a stimulus are converted into nerve impulses. Now consider the range of stimuli to which humans and other mammals are attuned and the manner in which the various sense organs carry out the transduction process. Many many more senses that just vision, hearing, touch, taste, smell. Human sensory systems are designed to extract from the environment the info that we need to function and survive. Have many different specialized sensors that can detect many different kinds of stimuli with considerable sensitivity. Psychophysics: studies relations between the physical characteristics of stimuli and sensory capabilities. Concerned with two kinds of sensitivity: concerns the absolute limits of sensitivity.
