question 77

Multiple Choice

• B) when acoustic coding was blocked, people often used visual coding.
• C) acoustic coding was even more likely in long-term memory than in working memory.
• D) semantic coding was the dominant mode in working memory, whereas acoustic coding was more likely in long-term memory.
