BLIND SPOT: place on retina where axons of all ganglion cells leave eye and where there are no receptors OPTIC CHASM point near base of brain where some fibres in optic nerve from each eye cross to other side of brain HUE: aspect of colour corresponds to names such as blue, red, green,yellow SATURATION: vividness or richness of a hue BRIGHTNESS: nearness of colour to white as opposed to black ADDITIVE COLOUR MIXING: process of mixing lights of different wavelengths to create new hue SUBTRACTIVE COLOUR MIXING: mixing paint pigments, each absorbs some wavelengths of light and reflects others TRICHROMATIC THEORY: all colour perception derives from three different colour receptors ( usually red,green, blue) OPPONENT-PROCESS THEORY: three sets of colour receptors (yellow-blue, red-green,black- white) respond to determine the colour experienced COLOUR BLINDNESS: partial or total inability to perceive hues FREQUENCY: number of cycles per second in wave; in sound determines pitch - how high or low sound is -measured in HERTZ

Unformatted text preview: HERTZ: cycles per second; unit of measurement for frequency AMPLITUDE: magnitude of wave; in sound determines loudness -measured in decibels DECIBEL: unit of measurement for loudness of sounds OVERTONES: tones that result from sound waves that are multiples of basic tone; primary determinant of timbre TIMBRE: the quality of texture of sound, caused by overtones AUDITORY NERVE: bundle of axons that caries signals from each ear to the brain OVAL WINDOW: membrane across the opening between the middle ear and inner ear that conducts vibrations to the cochlea COCHLEA: part of inner ear containing fluid that vibrates which in turn causes basilar membrane to vibrate BASILAR MEMBRANE: vibrating membrane in the cochlea of the inner ear; it contains sense receptors for sound PLACE THEORY: pitch determined by the location of greatest vibration on the basilar membrane -high frequency cause greatest vibration at stiff base of basilar membrane-low frequency at opposite end...
