Document Summary

You look with your eyes but see with your brain! Distal and proximal stimuli (steps 1 & 2) Distal stimulus (physical recycling box look at it and attend to it: environmental stimulus are all objects in the environment available to the observer, observer selectively attends to objects. Stimulus impinges on receptors resulting in internal representation. ex. The distal stimulus is the tree image goes to retina- creates a proximal stimulus (image reflected on retina is the proximal stimulus) Principle of transformation - when the stimuli and responses created by stimuli are transformed, or changed, between the environmental stimuli and perception. Sensory receptors are cells specialized to respond to environmental energy (ex. We have specialized cells in our eyes that respond to light: visual pigment is what reacts to light, transduction occurs, which changes environmental energy (ex. light) to nerve impulses. Rods and cones on back of eyes that change light into electrical energy and change how we perceive it.
