Question
Multiple Choice (1 point each; total of 21 of points) Chapter 4 MC 1) From the options below, select the true statement about stimuli. a. Identification of CSs and USs is relative Identification of CSs is relative, but USs do not need reference to other stimuli. c. Identification of USs is relative, but CSs do not need reference to other stimuli. d. Identification of CSs and USs does not rely on reference to other stimuli . 2) A rat is given 20 exposures to a red-light cue. Then, the red light is presented paired with food delivery. Compared to a rat that did not receive the initial 20 exposures, this rat took a long time to develop a CR to the red light. The slower learning is due to: a. the US-pre-exposure effect. b. the latent-inhibition effect. c. the latent-excitation effect. d. the CS relevance effect. 3) Increasing CS or US intensity has which of the following effects? a. speeds associative learning and makes the final level of conditioned responding greater b. speeds associative learning, but has little effect on the final level of conditioned responding c. makes the final level of conditioned responding greater, but has little effect on the speed of associative learning d. has little effect on the speed of associative learning or the final level of conditioned respondingExplanation / Answer
?Ans.[1] ? Identification of CSs and USs is relative [ ?key - concept ?]
?Ans. [2] The latent - in hibition effect.
?Ans.[3] ?Speed associative learning and makes the final level of conditioned responding greater [ ?fact ]
Ans. [4] ?After trainig a CS can function as a US.
Ans [5] ?CR comes to activate the UR directly.
?Ans.[6] ? The food US group will peck ,but water US group won't develop peacking respons.
