Question 12

Question MCQ▾

In a laboratory experiment, subjects wear headphones and are tested individually. Each of 500 subjects is presented first with a light and then possibly with a low-intensity tone in the earphones. Subjects are instructed to push a button if they hear a tone. Subjects are rewarded with $ 10 for each hit. In 500 trials, 200 times a tone was presented, and 300 times a tone was not presented. One hundred and ninety tones were detected. Also, the button was pressed 270 times in response to no tone.

Which of the following statements about the above experiment is in line with signal detection theory?

Choices

Choice (4)Response

a.

The reward for hits probably caused the high number of false alarms.

b.

Subjects were unable to detect at least a few tones because some tones were not a just noticeable difference from the previously presented tones.

c.

The reward offered for hits increased subjects overall response accuracy.

d.

The tone and the light were probably not effectively paired because the tone only followed the light in 200 of the 500 trails.
