Psycology

Sean just discovered that his roommate's girlfriend broke up with him. Later on, Sean sees his roommate studying in the library and assumes that he looks depressed. This assumption is an example of perception being influenced by:

a context effect

Are responsible for vision at bright light levels

cones

Railroad tracks appear to converge in the distance. This provides a cue for depth perception known as:

linear perspective

The principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage, rather than a constant amount, is called

Weber's Law

After hearing that Bryce had served a prison sentence, Janet began to perceive his genuinely friendly behavior as insincere and manipulative. This BEST illustrates the impact of:

perceptual sets

Mia is attracted to a man she is chatting with in a nightclub. What is probably happening to her eyes?

Her pupils are dilating

Are responsible for vision at low light levels

Rods

Closure

We fill in gaps to create a complete, whole object

Denise wears an extremely bright safety-yellow sweatshirt when she cycles to the gym after dark. The sweatshirt's brightness reflects the _____ of the light it reflects.

high amplitude

As you walk into a brightly lit room, the black structure in the center of your eye seems to shrink to a tiny black dot. This response is caused by the action of the eye structure called the:

iris

Some stroke victims lose the capacity to perceive motion but retain the capacity to perceive shapes and colors. Others lose the capacity to perceive colors but retain the capacity to perceive movement and form. These peculiar visual disabilities BEST illustrate our normal capacity for:

parallel processing

We group nearby figures together

proximity

Anna is reading her psychology text. The activation of receptors in her retina is called _____. Her interpretation of the stimuli as particular words is called _____.

sensation;perception

The phenomenon of perceptual set underscores the contribution of _____ processes to perception.

top-down

We perceive smooth, continuous patterns rather than discontinuous ones.

Continuity

BLANK are nerve cells that pass information about such visual elements as edges, lines, and angles to other cortical areas, where teams of cells respond to more complex patterns, such as faces.

Feature detectors

As you watch a dog play in the park, light reflected from the dog's fur first passes through three structures of your eye. In what order does the light pass through these structures?

cornea, pupil, lens

Why do our sensory systems adapt after prolonged exposure to a constant stimulus?

so that we detect potentially important changes in what's going on
