PYC1501 Unit 2 QUIZ QUESTIONS WITH CORRECT ANSWERS 2024 Sensation - ANSWERS the process by which our sensory receptors and nervous system receive/detect and represent stimulus energies from our environment- biochemical and neurological Perception - ANSWERS the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events, make judgements absolute threshold - ANSWERS the minimum intensity of stimulation that must occur before you experience a sensation signal detection - ANSWERS how and in what circumstances we can detect a stimulus; assumes there is no single threshold differential threshold - ANSWERS the ability of a sensory system to detect changes in or differences between two stimuli sensory adaptation - ANSWERS diminished sensitivity as a consequence of constant stimulation (e.g. wearing a hat) Ossicles - ANSWERS three tiny bones in the middle ear malleus - ANSWERS hammer; first of the three auditory ossicles of the middle ear incus - ANSWERS anvil; middle of the three auditory ossicles of the middle ear stapes - ANSWERS stirrup; last of the three auditory ossicles of the middle ear Pinna - ANSWERS the visible part of the ear concha - ANSWERS the concave shell of the ear; the deepest depression of the ear cochlea - ANSWERS a snail shaped, coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses chemical senses - ANSWERS taste and smell olfactory receptor cells - ANSWERS receive chemicals interpreted as smells, located in mucous membrane at the top of the nose olfactory bulb - ANSWERS a brain structure located above the nasal cavity beneath the frontal lobes Gustation (taste) - ANSWERS sensation that results from action of chemicals on taste buds gustatory cortex - ANSWERS area of the brain that receives and interprets tastes from the tongue, between frontal lobe and temporal lobe somaesthetic senses - ANSWERS Body senses, including the senses of touch, temperature, and pain, as well as the kinesthetic sense of where one's body parts are in relation to other body parts and to the environment. Somatosensation - ANSWERS The body senses, including body position, touch, skin temperature, and pain. tactile stimuli - ANSWERS Stimuli originating from texture Mechanoreceptors - ANSWERS respond to touch, pressure, vibration, and stretch, convert one kind on energy into another primary somatosensory cortex - ANSWERS the region of the anterior parietal lobe whose primary input is from the somatosensory system Proprioception - ANSWERS our sense of body position Cornea - ANSWERS the transparent outer covering of the eye Retina - ANSWERS the light-sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information optic nerve - ANSWERS the nerve that carries neural impulses from the eye to the brain light intensity - ANSWERS how much energy the light contains light wavelength - ANSWERS the distance between the Photoreceptors - ANSWERS rods and cones Rods - ANSWERS retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision, when cones don't respond Cones - ANSWERS color vision Agnosia - ANSWERS the inability to recognize familiar objects. Prosoagnosia - ANSWERS inability to recognize faces ventral pathway - ANSWERS Pathway of visual processing. The "what" pathway. dorsal pathway - ANSWERS Pathway of visual processing. The "where" pathway. trichromatic theory of color vision - ANSWERS The theory that the sensation of color results because cones in the retina are especially sensitive to red light (long wavelengths), green light (medium wavelengths), or blue light (short wavelengths). opponent-process theory - ANSWERS the theory that opposing retinal processes (red-green, yellowblue, white-black) enable color vision. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green
