Question 5
Multiple Choice Question
Question
PASSAGE 2 — SLEEP AND MEMORY
Students learned forty word pairs and were randomly assigned either to sleep for eight hours or to remain awake for an equivalent interval. The sleep group recalled more pairs the next morning. Electroencephalographic recordings showed that, within the sleep group, greater slow-wave activity predicted better recall. A separate recognition test included studied words and similar but unstudied lure words. Sleep improved correct recognition without increasing false alarms to the lures.
QUESTION 5: The correlation between slow-wave activity and recall, considered by itself, permits which conclusion?
Explanation
Correct Answer: B
ANSWER
Correct Answer: B
Method / Topic: Psychology
The correct answer is B: Greater slow-wave activity was associated with better recall. A correlation establishes an association but does not by itself determine causal direction or eliminate third variables. The data support that participants with more slow-wave activity tended to recall more pairs.
Why this answer is correct
The correct option matches the required rule and the given information.
Short Explanation
The correct answer is B: Greater slow-wave activity was associated with better recall. A correlation establishes an association but does not by itself determine causal direction or eliminate third variables. The data support that participants with more slow-wave activity tended to recall more pairs.
