"Good" TV visuals: do they make a difference?
Media producers generally urge health science instructors to plan television visuals that conform to accepted ideas of what is "good" for television.

It was found that alterations in these characteristics did not affect performances on post-tests, but the students did have definite preferences in some areas.
