AP psych- sensation and perception

Sensation

the process of the sensory organs transforming physical energy into neurological impulses the brain interprets as the five senses of vision, smell, taste, touch, and hearing

Absolute Threshold

the smallest level of energy required by an external stimulus to be detectable by the human senses

Retina

Cones

specialized types of photoreceptors that work best in bright light conditions

Difference Threshold

A difference threshold is the minimum required difference between two stimuli for a person to notice change 50% of the time

Perception

our recognition and interpretation of sensory information

Rods

specialized photoreceptors that work well in low light conditions
