Peer reviewedAlexander, Gerald; Beale, Ivan L. – Australia and New Zealand Journal of Developmental Disabilities, 1990
An intellectually handicapped man was studied in a workshop where he was employed to "detip" ear tags. Productive behavior was reinforced on either a variable ratio (VR) schedule or a variable duration (VD) schedule. Results indicated lower time on task and higher detipping rates under the VR schedule. (Author/PB)
