Question

What will happen if the CS is presented many times in the absence of the US?​

Quizplus · Accepted Answer

The CS will no longer elicit the CR because it is not being paired with the US, which means there is no learned association between the two stimuli. This is known as extinction. Option A is incorrect because the CS needs to be paired with the US initially to elicit a CR. Option C is incorrect because the presentation of the CS does not affect the UR. Option D is incorrect because while the CS may no longer elicit the CR, the absence of the US does not affect the UR.
