Chapter 6 – Perception & AttentionoSensation: bottom-up processing, transduction. oPerception: top-down processing. oHabituationDecreased response to a stimulusLearning to be bored, losing interestStimulus discriminationoPreferential looking or visual preference methodTwo objects are presented togetherLooking longer at one (showing a preference) indicates they can tell a difference Cross-modal matching- looking at one they have already experienced in another modalityoAccommodation- changing the shape of the lens in order to bring things into focus oAcuity- sharpness; the ability to perceive detail; ability to distinguish two points close togetherVisual acuity at 1 month?
