Define These Visual Sensation Terms Flashcards

The police officer sometimes shines a light into the driver's eye. This typically results in the contraction of the _____, which controls the size of the pupil and thus the amount of light entering the eye. Iris _____ is the process by which we detect physical energy in the environment and encoding that energy as neural signals. Sensation The opponent-process theory is MOST useful for explaining the characteristics of: afterimages Cones or rods are: more light-sensitive and less color-sensitive than cones. Rods The size of the difference threshold is greater for heavier objects than for lighter ones. This best illustrates: Weber's Law When attending an extremely loud concert, your absolute threshold for sound is likely to: increase The detection and encoding of stimulus energies by the nervous system is called: stimilus this can briefly influence attitudes, thoughts, preferences and emotions subliminal stimuli in dim lighting, your _____ are ineffectual cones feature detectors are located in the: visual cortex The opponent-process theory is MOST useful for explaining the characteristics of: afterimages brightness is to amplitude as hue is to: wavelength the ____ of a color corresponds to the purity of a light wave saturation The area where the optic nerve leaves the retina is referred to as the: blind spot where is the visual cortex located? back of the brain The adjustable opening in the center of the eye through which light enters is called the: pupil where are feature detectors located? the visual cortex photoreceptors, bipolar cells, ganglion cells is the correct path that leads to what nerve? optic nerve ___ occurs below your absolute threshold for conscious awareness. subliminal stimulation The retina's central focal point is the _____, which contains only cones, no rods. fovea As a result of the absence of _____ in the _____ part of the eye, we have a tiny hole, known as a blind spot, in our field of vision. photoreceptors; optic disk five main types of taste sensations are: salt, sour, bitter, sweet and savory ____ plays a role in the reproductive behavior of many species. pheromones __ fibers is fast pain system__fibers is slow pain system A-delta; C what makes up the inner ear? cochlea, semicircular canals and vestibular sacs Also resembling a snail, the _____ is a fluid-filled tube that contains the basilar membrane and hair cells. cochlea According to the _____ theory, the spinal cord contains a neurological gate that either blocks pain signals or allows them to pass on to the brain. gate control Which structure involved in hearing corresponds MOST closely in function to the photoreceptors in the retina for vision? hair cells touch includes the four basic sensations: pressure, pain, warmth and cold In terms of the transduction of physical energy into coded neural messages, the _____ is to the eye as the _____ is to the ear. retina; cochlea Umami = meat, cheese and MSG top-down processing = conceptually driven processing This Gestalt psychologist was the first to study the illusion of motion, known as induced motion. Karl Duncker The phenomenon that involves the misperception of the length of two identical lines, one with arrows pointing outward, and one with arrows pointing inward is called the: Müller-Lyer illusion ___ is not a monocular for depth similarity This Gestalt psychologist was the first to study the illusion of motion, known as stroboscopic motion. Max Wertheimer Monocular depth cues rely on the relationship between_____ and _____ distance and size The Gestalt psychologist, _____, was the first to study the illusion of motion, known as induced motion. Karl Dunker The Gestalt psychologist _____ was the first to study the illusion of motion, known as stroboscopic motion. Max Wertheimer _____ occurs when one object partially blocks our view of another, we perceive it as closer. interposition
