Partial access to a word's features shows that the item is in memory but retrieval fails for the moment, supporting retrieval failure as a cause of forgetting.
Answer: B · Holophrase
In the one-word stage, children use holophrases: single words that carry the meaning of a full sentence, often clarified by gesture and context.
Answer: C · More help after failure and less help after success

Answer: B · Number of the sources
Social impact depends on the sources' strength (status), immediacy (closeness) and number. Each extra source adds less impact than the one before.
Answer: D · Members suppressed doubts and assumed everyone agreed
Janis described symptoms such as self-censorship, an illusion of unanimity and pressure on dissenters, leading to a poorly examined plan.
