AP Psychology Unit 4 Crossword

The process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment
The process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events
Analysis that begins with the sensory receptors and works up to the brain's integration of sensory information
nformation processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations
The focusing of conscious awareness on a particular stimulus
Failing to see visible objects when our attention is directed elsewhere
Failing to notice changes in the environment
Conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impulses our brains can interpret.
The study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them
Minimum stimulation needed to detect a particular stimulus 50% of the time
A theory predicting how and when we detect the presence of a faint stimulus ("signal") amid background stimulation ("noise").
Below one's absolute threshold for conscious awareness
The activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response
The minimum difference between two stimuli required for detection 50 percent of the time. We experience the difference threshold as a just noticeable difference. (Also called just noticeable difference or jnd.)
The principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount)
Diminished sensitivity as a consequence of constant stimulation
A mental predisposition to perceive one thing and not another
The controversial claim that perception can occur apart from sensory input; includes telepathy, clairvoyance, and precognition.
The study of paranormal phenomena, including ESP and psychokinesis
The distance from the peak of one light or sound wave to the peak of the next. Electromagnetic wavelengths vary from the short blips of cosmic rays to the long pulses of radio transmission
The dimension of color that is determined by the wavelength of light; what we know as the color names blue, green, and so forth
The amount of energy in a light or sound wave, which we perceive as brightness or loudness, as determined by the wave's amplitude
he adjustable opening in the center of the eye through which light enters
A ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening.
The transparent structure behind the pupil that changes shape to help focus images on the retina
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.
The process by which the eye's lens change shape to focus near or far objects on the retina
Retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision, when cones don't respond
Retinal receptor cells that are concentrated near the center of the retina and that function in daylight or in well-lit conditions. The cones detect fine detail and give rise to color sensations
The nerve that carries neural impulses from the eye to the brain
The point at which the optic nerve leaves the eye, creating a "blind" spot because no receptor cells are located there
Central focal point in retina, where eye's cones cluster.
Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement
