Eyes
the light sensitive inner surface of the eye containing receptor rods and cones plus the processing of visual information.
What is red, blue, and green?
This is the visible part of the ear.
What is the pinna?
Minimum stimulation necessary to detect light, sound, pressure, taste and odor 50 percent of the time.
Absolute Threshold
The method by which the sensations experienced at any given moment are interrupted and organized in some meaningful fashion.
What is perception?
The tendency for parallel lines to appear to converge on each other.
What is linear perspective?
This part of the eye is responsible for controlling how much light enters the eye.
What is the iris?
Psychological experience of sound that corresponds to the frequency of the sound waves.
What is pitch?
Stimuli you cannot detect 50 percent of the time are
subliminal
An organized whole. Getsalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes.
The Gestalt Principle
A visual stimulus that fools the eye into seeing something that's not real is called this.
What is an illusion?
This carries neural impulses from the eye to the brain.
optic nerve
The coiled bony, fluid - filled tube in the inner ear; sound waves traveling through the cochlear fluid trigger nerve impulses.
Cochlea
The activation, often unconsciously, of certain associations, thus predisposing one's perception, memory or response.
or
A phenomenon in which exposure to a stimulus, such as a word or image, influences how one responds to a subsequent, related stimulus.
What is priming.
When assembling a puzzle without a picture of the completed puzzle you are using this.
What is bottom-up processing?
The tendency to perceive a quarter as being round even when it is viewed at an angle is called this.
What is shape constancy?
retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions.
What are cones?
This type of hearing loss is likely to develop when the bones of the middle ear are damaged.
What is conduction hearing loss.
The minimum difference in stimulation that a person can detect 50 percent of the time.
Difference Threshold
The organization of the visual field into objects that stand out from their surroundings.
What is Figure Ground
An illusion of movement created when two or more adjacent lights blink on and off in quick succession.
What is the Phi Phenomenon.
Define Accommodation
the process by which the eye's lens changes shape to focus near or far objects on the retina.
define the hammer and what it does.
A tiny bone that passes vibrations from the eardrum to the anvil
A theory predicting how we detect the presence of a faint stimulus (signal) amid background stimulation (noise)
Signal detection theory
Depth Cues, such as interposition and linear perspective available to either eye alone.
Monocular Cues
Perceiving objects as unchanging (having consistent brightness, shape, size and color) even as illumination and retinal images change.
What is Perceptual Constancy.
