5.1 Sensation vs. Perception

sensation

activation of receptors in various sense organs

perception

method by which sensations are organized and interpreted

“change blindness”

occurs because humans are able to pay attention to only part of the visual sensation that they are exposed to on a moment to moment basis

absolute threshold

least energy for correct stimulus detection 50% of the time

just noticeable difference

smallest difference detectable 50% of the time

sublime threshold

presented below the threshold for conscious awareness (subliminal messages)

sensory adaptation

sensory receptors less responsible to constant stimuli (biological)
