Match the following

• bottom-up processing

• the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.

• Sensation

• information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations.

• top-down processing

• the process of organizing and interpreting sensory information enabling us to recognize meaningful objects and events.

• perception

• analysis that begins with the sensory receptors and works up to the brain's integration of sensory information.

Match the following

• choice blindness

• The inability to detect changes between two voices

• selective attention

• failing to see visible objects when our attention is directed elsewhere.
• change deafness

• failure to recall a choice immediately after we have made that choice

• change blindness

• failing to notice changes in the environment.

• inattentional blindness

• the focusing of conscious awareness on a particular stimulus.

Match the following

• signal detection theory

• 
  the minimum difference between two stimuli required for detection 50 percent of the time. We experience the difference threshold as a just noticeable difference (or jnd).

• difference threshold

• the minimum stimulation needed to detect a particular stimulus 50 percent of the time.

• psychophysics

• the study of relationships between the physical relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them.

• absolute threshold

• 
  a theory predicting how and when we detect the presence of a faint stimulus (signal) amid background stimulation (noise). Assumes that there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and alertness.

• transduction

• 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 brain can interpret.

Match the following

• emotion adaptation

• emotions are formed based on the appraisal of the environment

• Weber's Law

• diminished sensitivity as a consequence of constant stimulation.

• priming

• the principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount).

• sensory adaptation

• the activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response.

perceptual set is a set of mental tendencies and assumptions that affects, ______ ________, what we hear, taste, feel and see.

• top-down

• bottom-up

Match the following

• cornea

• The clear tissue that covers the front of the eye

• Pupil

• the adjustable opening in the center of the eye through which light enters

• lens

• a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening

• retina

• 
  the transparent structure behind the pupil that changes shape to help focus images on the retina

• Iris

• 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

Match the following

• amplitude

• determines wavelength...a high one = a short wavelength. A low one = a long wavelength

• Intensity

• The distance between two corresponding parts of a wave

• Wavelength

• determines a wave's intensity, or height. A small one = dull colors. A great one = bright colors.

• frequency

• the dimension of color that is determined by the wavelength of light; what we know as the color names blue, green, and so forth

• hue

• the amount of energy in a light or sound wave, which we perceive as brightness or loudness, as determined by the wave's amplitude

Match the following

• optic nerve

• the point at which the optic nerve leaves the eye, creating a "blind" spot because no receptor cells are located there

• cones

• 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.

• blind spot

• the central focal point in the retina, around which the eye's cones cluster

• fovea

• retinal receptors that detect black, white, and gray; necessary for peripheral and twilight vision, when cones don't respond

• rods

• the nerve that carries neural impulses from the eye to the brain

Match the following

• depth perception

• By comparing retinal images from the two eyes, the brain computes distance - the greater the difference between the two images, the closer the image

• monocular cue

• the ability to see objects in three dimensions; allows us to judge distance

• retinal disparity

• a depth cue, such as interposition or linear perspctive, available to either eye alone

• binocular clue

• a device for testing depth perception in infants and young animals

• visual cliff

• a depth cue that depends on the use of two eyes

Alison opened her new jigsaw but soon realized that the puzzle pieces inside had nothing to do with the picture on the box.  She completed the puzzle without knowing what the finished picture would look like.  Which of the following did Allison use?

• bottom-up processing
• top-down processing
