Document Summary
Sensation refers to the ability of detecting of sensory information: sensory awareness: visual, auditory, etc Perception refers to interpretation of sensation: perception implies organization and understanding of meaning of sensations, how the brain interprets sensation. Ex: if 2 people hear someone speaking, 1 person might hear it as normal, the other as loud. Attention refers to selective perception: focus on certain stimuli while ignoring others. Habituation: new experience gets more attention. Once that new information has been experiences, the person"s reaction returns to being normal (not as much attention) In a state of habituation, you have no reaction. Not an increase or decrease: disbahituation would get a higher reaction. High amplitude sucking method: child rigged to a machine that measures baseline to sucking on a pacifier, and then new info introduced, and there will be an increase in sucking on the pacifier. Once it is represented, there is a return to baseline.
