WEEK 6SENSATION & PERCEPTIONChapter 4
VISION
Wavelength (hue) Amplitude Purity Cornea Lens Iris Pupil Retina Transduction
Optic disk Optic nerve Rods Cones Light Nearsightedness Farsightedness Receptive fields Convergence Vision acuity
HEARING OTHER SENSES
Wavelength Amplitude Purity Pinna Ossicles Cochlea Semicircular canals
Gustation Primary tastes Nontasters vs
supertasters
Olfaction
Kinesthetic Vestibular
PERCEPTION
Reversible figure Perceptual sets Inattentional blindness Top- down processing
(aka form perception theory)
Bottom-up processing (aka feature detection theory)
Subjective contours
Gesalt principles: Figure-ground Proximity Similarity Continuity Closure Simplicity
Pictorial depth cues Optical illusions Motion parallax After image
KEY TERMS
Sensation Threshold Absolute Threshold Just noticeable difference Signal detection theory Subliminal perception Mere-exposure effect Sensory adaptation Trichromatic theory Opponent Process Theory Phi phenomenon(Apparent motion)
