Exam 5: Sensation and Perception

When we watch a motion picture, we perceive it as continuous even though it is really being shown at 24 frames per second. This is because of the Gestalt principle of

Recognition of a visual target requires that the neural information ultimately reaches the

Becky is very sad when it is time to say goodbye to her grandmother after visiting her. Her mother and father load the luggage into the car while Becky gives grandma one last hug and bids good-bye. As the family car drives away, Becky keeps waving to her grandmother until her grandmother has gotten so small that she can no longer see her. Suddenly, Becky bursts into tears, crying that her grandmother just got smaller and smaller until she disappeared and Becky is afraid she is dead! What Becky does not understand is that perception utilizes principles of

Signals from pain receptors are sent to the ______________ and then on to other areas of the cortex.

The Gestalt law of continuity would be considered an example of top-down processing.

Research has found that people in all cultures studied so far utilize monocular depth cues to the same extent and in the same ways.

According to psychologists, the stimulus-detection process in which sensory receptors translate external stimuli into nerve impulses is called _______________.

The chemical receptors concentrated along the edges and back surface of the tongue are called __________________.

The area of scientific study that is concerned with people's abilities to detect differences or changes in stimuli is called _______________.

Promise Technology has just introduced a new hearing aid. Which of the following disorders should most likely be helped by this invention?

In the process of trying to recognize a stimulus, we compare the current stimuli against mental representations known as

Psychologists who study perception think that each of our perceptions is like a hypothesis that is tested by comparing an incoming stimulus to a pre-existing ________________.

You are observing sound waves being produced on the cochlea and notice that an abrupt wave peaks close to the oval window. According to von Bekesy and the place theory of auditory perception, you interpret this event as a

Let's say that you are testing an individual's ability to discriminate tones. When the test stimulus is set at 200 Hz, the person reports a JND at 210 Hz. If I change the test frequency, the value of a JND becomes 50 Hz. What is the new test frequency?

The sensory system takes in individual elements of the stimulus and then combines them into a unified perception in ______________ processing.

Which one of the following statements is false?

Perception has been likened to the process of creating a theory, and perceptual sets are the representations or images that we make use of to test our perceptual theories.

By what route do rods and cones send neural messages to the brain?
