Document Summary
Observing the simulus (ex. tree: step 2: light relects of the simulus and is transformed. Simuli and responses created by simuli are transformed, or changed, between the environmental simulus and percepion. 1st transformaion is when light hits the simulus and is relected back into the person"s eye. When light hits the eye it is transformed as it is focused by the eye"s opical system (cornea and lens) and forms an image on the person"s reina. Cells specialized to respond to environmental energy, with each sensory system"s receptors specialized to respond to a speciic type of energy. Visual receptors respond to light, auditory receptors respond to pressure changes in the air: when visual receptors receive relected light they do 2 things: They shape percepion by the way they respond to simuli: transducion. Transformaion of one for of energy to another. Ex. transforming light energy into electrical energy in the visual system. Happens because of visual pigment, a light-sensiive chemical, which.
