Tim Wilson,Pat Laser,and Julie Stone (1982)asked Participants to Keep Journals

Tim Wilson,Pat Laser,and Julie Stone (1982) asked participants to keep journals of their daily moods and of other variables,such as the weather and how much sleep they got the night before.When asked,many participants reported the amount of sleep the night before was correlated with their moods.When information recorded in the journals was subjected to more systematic statistical analysis,it was found that amount of sleep was not related to participants' self-reported moods.This is most likely because participants

A) under-reported the amount of sleep they actually got.
B) were in a bad mood from having to keep the journal.
C) were distracted (e.g., by loud noise) when they wrote in their journals.
D) relied on causal theories about the relation between mood and sleep.
E) did not keep accurate journals.
