Question 1

In the perceptual process, ____________ is the transformation of one form of energy to another.

Answer 1

Transduction

Question 2

The clinical disorder of visual form agnosia was provided as an example of how we might fail to __________ an object, even though we detect the features of the object.

Answer 2

recognize

Question 3

In a perception experiment, you would like to measure the experience of the subject in response to some stimulus being presented. Since their experience is not directly observable, the experimenter must create _______________ which give us something that can be directed observed.

Answer 3

operational definitions

Question 4

According to Marr’s levels of analysis, the _________ level is the most abstract and tries to characterize the nature of the problems solved by the system.

Answer 4

computational

Question 5

You design a study that examines color vision by recording the outputs of specific receptor cells (cones and rods) in response to the presentation of particular samples of colored lights. You conclude that particular colored lights cause specific pattens of responses in the cone receptors. What is the deepest of Marr’s levels of analysis that fits this explanation?

Answer 5

Implementation

Question 6

You perform an auditory experiment in the Psychology department. The experimenter asks you to press button “A” when two tones presented have unequal loudness. Otherwise, you are supposed to press “B” if they seem to have equal loudness. You notice that some pairs of tones are harder to judge than others. What is being measured in this experiment?

Answer 6

Difference threshold

Question 7

Which of the quantitative methods listed below is most accurate when attempting to find the absolute threshold for detecting a stimulus?

Answer 7

Method of constant stimuli

Question 8

When determining the difference threshold for a given sensory dimension, Weber’s law suggests that as the value of the standard increases, the value of DL will _________.

Answer 8

increase

Question 9

Response ________ in a magnitude estimation experiment occurs when doubling the stimulus intensity LESS than doubles the subjective magnitude of the stimulus.

Answer 9

compression

Question 10

1. Psychophysics attempts to identify regularities between the physical properties of stimuli and the psychological states they induce in observers. When a lawful relationship between stimuli and sensations is defined (e.g. Steven’s Power Law), this seems to best fit which of Marr’s levels of analysis?

Answer 10

Algorithmic
