Chapter 3 Review Sensation and Perception

If you look at a painting on the other side of the room with first your right and then your left eye, the images look virtually identical. However, if you place your index finger in front of your nose one eye at a time, the two images look very different from one another. The phenomenon is an example of which distance cue?

Binocular cues

Cones allow us to see in black and white, while rods provide color vision. Cones are more sensitive to dim light than rods are.

False

When Darren first started working in the poultry plant, he found the smell from the chickens to be overwhelming. However, he gradually became accustomed to the smell, and now it no longer bothers him. This scenario illustrates an instance of _____.

Negative Adaptation

On a bright, sunny day, Manny leaves a dimly-lit movie theater and goes out into the street. The _____ in his eyes adjust to the sudden increase in light.

Pupils

The difference between sensation and perception is that sensation, or the stimulation of our senses, is an automated process resulting from sources of energy (light and sound) or the presence of chemicals (as in taste and smell), while perception is an active process in which sensations are organized and interpreted to form an inner representation of the world.

True

The thin, light sensitive membrane that lies at the back of the eye and contains the sensory receptors for light is the ____.

Retina

The _____ refers to the smallest possible stimulus that can be detected half the time, or the minimum level of stimuli that we can detect.

Difference Threshold

Why do the two lines in the Müller-Lyer illusion appear to be of different lengths even though they are the same length?

Due to the principles of perceptual organization.

The blind spot:

Is insensitive to visual stimulation

Jeff observed a quick succession of cars moving together on the road. His first thought was that they were all a part of a convoy of some sort. Which law of perceptual organization best explains Jeff's assumption?

The law of common Fate

Which of the following is not a principle of Gestalt psychology?

Weight

How many rods does each eye contain?

125 Million

The axon bundle that transmits neural impulses from the organ of Corti to the brain is known as the__________.

Auditory Nerve

Visual acuity is highest when images are focused on the fovea because of the high concentration of ____ in the region.

Cones

When we think of the eye as the camera to the world, the photosensitive surface is called the lens, which contains photoreceptors called rods and cones.

False

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

Which of the following statements is true of the absolute threshold?

It is determined by exposing individuals to progressively stronger stimuli until the minimum stimuli the person can detect is found.

The __________ conducts sensory input to the brain, where it is relayed to the visual area of the occipital lobe.

Optic nerve

_____ is a monocular cue for depth based on the coming together of parallel lines as they recede into the distance.

Perspective

__________refers to the tendency to perceive a broken figure as being complete or whole

Principle of Closure
