title: Pencil lead diameter affects response sheet completion time.
abstract: The effect of pencil lead diameter on the completion time of a multiple-choice response sheet was examined. Participants used three pencil lead diameters (.5 mm, .9 mm, and a standard No. 2 pencil) to fill in "bubbles" on response sheets in one experiment; a .7-mm pencil was substituted for the No. 2 pencil in Exp. 2. Participants using a .5-mm pencil completed response sheets more slowly than when using a .7-mm, .9-mm, or a No. 2 pencil.
