spondi 7) Which experimental technique might a researcher use to determine whether conditioned res is due to S-S or S-R learning? a. run test trials with a novel CS b, run test trials with a novel US c. Use of CS devaluation techniques d. Use of US devaluation techniques 8) The drug dinitr rophenol (US) causes increased oxygen consumption (UR). According to the concept of te UR which of the following is true regarding exposure to cues associated with the effect of dinitrophenol? a. will also increase oxygen consumption b. will decrease oxygen consumption c. will not alter oxygen consumption d. will not actually alter oxygen consumption, but subjects will report a change in the affective aspects of oxygen consumption 9) The blocking effect demonstrates which of the following? a. that temporal contiguity is sufficient for associative learning b. that CS-US pairings are sufficient for associative learning c. that contiguity and CS-US pairings, when they occur together, are sufficient for d. that CS-U S pairings (contiguity) are an insufficient explanation by themselves for associative learning 10) According to Kamin, the blocking experiment, which involves training with a single CS-US pairing followed by compound stimulus-US pairings (i.e., CS1+CS2) demonstrates that a CR to CS2 would not occur because a. the CS2 is less surprising and expected b. the US is less surprising and is no longer as salient as it was in the first CS1-US pairing c. the CS1 is expected and less surprising d. the US is unexpected and holds greater value or saliency 11) Which model suggests that whether conditioned responding reflects excitation or inhibition depen on the excitatory value of the CS and the excitatory value of contextual cues present during training? a. the Rescorla-Wagner model b. the comparator hypothesis c. attentional models d. temporal models Chapter 5 MC 12) The cats in Thorndike's puzzle boxes were able to escape more quickly over successive trials. Thorndike interpreted this performance change to reflect which type of learning? a. stimulus-outcome learning b. stimulus-stimulus learning. c. stimulus-response learning. d. response-outcome learning 13) Which of the following would most likely be used in a discrete trial procedure? a. licking water from a tube to gain access to food b. pressing a lever to gain access to food c. finding the correct arm in a T-maze that leads to termination of aversive stimulus d. pushing a rod to gain access to foodExplanation / Answer
Chap 5
Ans 19.(c) Positive reinforcement refers to adding a stimulus that reinforces a behavior. For example when a kid makes his bed (behavior) and gets a candy afterward (adding a stimulus) from his mother as a reward. Positive reinforcement is a part of operant conditioning.?
Ans 12.(c) stimulus-response learning
Ans.14 (a) response rate
Ans 15 (b) pushing a lever with a paw and pushing a lever with the snout are equivalent
Ans 16. (c) classical conditioning
Ans 17.(d) 5'
Ans 18. (b) free Operant methods provide the opportunity to observe changes in the likelihood of behavior over time, which allows for analysis of behavior in meaningful units.
Ans 20.(b) behavioral variability can be the basis for instrumental reinforcement.
Ans 21. (b) belongingness
