Which TWO of the following statements are true of blocking? 1: The phenomenon of blocking provides an interesting and much-studied instance of failure to learn, in spite of contiguous presentations of the CS and the US 2: In a blocking experiment, animals receive training with what is termed a compound CS (Phase 2) 3: The experimental group has first received a phase of training in which the US alone is conditioned (Phase 1) 4: The experimental groups shows no (or very little evidence of learning about the CS that is presented in Phase 1
Correct answer: A. 1 & 2
- A. 1 & 2
- B. 2 & 3
- C. 3 & 4
- D. 1 & 3
Explanation
Blocking demonstrates that a previously trained CS can prevent learning about a new CS, even when the new CS is paired contiguously with the US. The usual design uses a single CS-US phase followed by compound-CS training, so statements 1 and 2 are correct; the other statements reverse the phases or identify the wrong stimulus.
