Question
Answer
sensation   show
🗑
perception   show
🗑
sensory receptors   show
🗑
show the process by which a form of physical energy is converted into a coded neural signal that can be processed by the nervous system  
🗑
absolute threshold   show
🗑
difference threshold   show
🗑
Weber's law   show
🗑
subliminal perception   show
🗑
mere exposure effect   show
🗑
show the decline in sensitivity to a constant stimulus  
🗑
wavelength   show
🗑
show a clear membrane covering the visible part of the eye that helps gather and direct incoming light  
🗑
show the opening in the middle of the iris that changes size to let in different amounts of light  
🗑
show the colored part of the eye which is the muscle that controls the size of the pupil  
🗑
lens   show
🗑
show the process by which the lens changes shape to focus incoming light so that is falls on the retina  
🗑
show a thing, light-sensitive membrane, located at the back of the eye, that contains the sensory receptors for vision  
🗑
show the long, thin blunt sensory receptors of the eye that are highly sensitive to light, but no to color, and that are primarily responsible for peripheral vision and night vision  
🗑
show the short, thick, pointed sensory receptors of the eye that detect color and are responsible for color vision and visual activity  
🗑
fovea   show
🗑
show area of the retina without rods or cones, where the optic nerve exits the back of the eye  
🗑
show the point at which the optic nerve leaves the eye, producing a small gap in the field of vision  
🗑
show in the retina, the specialized neurons that connect to the bipolar cells; the bundled axons of the ganglion cells form the optic nerve  
🗑
bipolar cells   show
🗑
optic nerve   show
🗑
optic chiasm   show
🗑
color   show
🗑
hue   show
🗑
saturation   show
🗑
show the perceived intensity of a color, which corresponds to the amplitude of the light wave  
🗑
show the theory that the sensation of color results because cones in the retina are especially sensitive to red light(long), green light(medium), or blue light(short)  
🗑
show one of several inherited forms of color deficiency or weakness in which an individual cannot distinguish between certain colors  
🗑
afterimage   show
🗑
opponent-process theory of color vision   show
🗑
show the technical term for the sense of hearing  
🗑
show the intensity (or amplitude) of a sound wave, measured in decibels  
🗑
amplitude   show
🗑
show the unit of measurement for loudness  
🗑
pitch   show
🗑
frequency   show
🗑
show the distinctive quality of a sound, determined by the complexity of the sound wave  
🗑
show the view that different frequencies cause larger vibrations at different locations along the basilar membrane  
🗑
olfaction   show
🗑
show technical name for the sens of taste  
🗑
show the enlarged ending of the olfactory cortex at the front of the brain where the sensation of smell is registered  
🗑
phermones   show
🗑
show the specialized sensory receptors for taste that are located on the tongue and inside the mouth and throat  
🗑
pain   show
🗑
show specialized sensory receptors for pain that are found in the skin, muscles, and internal organs  
🗑
show a neurotransmitter that is involved in the transmission of pain messages in the brain  
🗑
show the theory that pain is a product of both physiological and psychological factors that cause spinal gates to open and relay patterns of intense stimulation to the brain, which perceives them as pain  
🗑
kinesthetic sense   show
🗑
show sensory receptors, located in the muscles and joints, that provide information about body position and movement  
🗑
vestibular sense   show
🗑
show information processing that emphasizes the importance of the sensory receptors in detecting the basic features of a stimulus in the process of recognizing a whole pattern; analysis that moves from the parts to the whole  
🗑
show information processing that emphasizes the importance of the observer's knowledge, expectations, and other cognitive processes in arriving at meaningful perceptions; analysis that moves from the whole to the parts  
🗑
ESP (extrasensory perception)   show
🗑
show the scientific investigation of claims of paranormal phenomena and abilities  
🗑
show A school of psychology founded in Germany in the early 1900s that maintained that our sensations are actively processed according to consistent perceptual rules that result in meaningful whole perceptions, or gestalts.  
🗑
Max Wertheimer   show
🗑
show a Gestalt principle of perceptual organization that states that we automatically seperate the elements of a perception into the feature that clearly stands out (the figure) and its less distinct background (the ground)  
🗑
depth perception   show
🗑
monocular cues   show
🗑
binocular cues   show
🗑
show the tendency to perceive objects, especially familiar objects, as constant and unchanging despite changes in sensory input  
🗑
size constancy   show
🗑
shape constancy   show
🗑
perceptual illusion   show
🗑
show A famous visual illusino involving the misperception of the identical length of two lines, one with arrows pointed inward, one with arrows pointed outward  
🗑
show A visual illusion inolving misperception that the moon is larger when it is on the horizon than when it is directly overhead  
🗑
perceptual set   show
🗑
show Technique that involves using auditory or visual feedback to learn to exert voluntary control over, involuntary body functions, such as heart rate, blood pressure, blood flow, and muscle tension  
🗑
acupuncture   show
🗑
Karl Duncker   show
🗑
show The people, trees, and lampposts toward the bottom of the photo seem closer because they are lager than those toward the center  
🗑
show Many objects in the photograph are partially obscured by other objects-such as trees. In each case, the object that is not obscured is perceived as being closer  
🗑
show The towers toward the top of the photo are fuzzy and slightly blurred, and thus they are perceived as being farther away  
🗑
Texture gradient   show
🗑
Linear perspective   show
🗑
show Sensory adaptation  
🗑
show absolute threshold  
🗑
The sensory receptors that respond to different wavelengths of light and allow us to perceive color are the   show
🗑
show  
🗑
show Gestalt's Principle of Grouping  
🗑
show Monocular cues  
🗑
show linear perspective  
🗑
show binocular cue  
🗑
show Overlap  
🗑
The visual system information about depth from the slightly different images seen by your left and right eye. This depth cue is called:   show
🗑
The visual system obtains information about depth from the slightly different images seen by your left and right eye. This is an example of a:   show
🗑
The tendency to see objects as constant and unchanging despite changes in the retinal image is called:   show
🗑
The retinal image of door viewed at an angle is not rectangular, yet the door is still perceived to have a rectangular shape. This phenomenon is called   show
🗑
