At the end of a trial, the judge gives jurors a set of instructions that ex
plain the laws that are applicable to the case and that direct jurors to re
ach a verdict in accordance with those laws. Little is known about how well
jurors understand instructions in civil cases. We assess the extent to whi
ch jurors understand judicial instructions in negligence cases. We address
3 issues: (a) To what extent do they understand these instructions? (b) To
what extent is their comprehension enhanced by access to a written copy of
the instructions? and (c) What effect does deliberation have on jurors' com
prehension levels? Overall comprehension was approximately 64% and access t
o written instructions did not enhance comprehension, but the opportunity t
o deliberate did.
