Replication Effort Finds No Evidence That Grammatical Aspect Affects Perceived Intent
Marlene Breverman stashed this in Psychology
"... subjects read a passage describing the shooting of one man by another man after a gambling disagreement. One version of the passage was written in a form called the imperfective aspect (Westmoreland was firing gun shots), and the other passage was written in the perfective aspect (Westmoreland fired gun shots)."
I try not to use the imperfective aspect. Seems simpler and more straightforward to use the perfective.
