| Abstract: | In individual sessions, an adult directed three boys to work on each of three different tasks. Within a given session the on-task behavior for one task was praised, the off-task behavior for another task was verbally reprimanded, and all behavior was ignored with the third task. Using a multielement baseline design, the manner in which the adult interacted with the children on a given task varied from day to day. Across 18 sessions, verbal reprimands produced the highest task rates, with praise producing only a slightly higher rate of responding than noninteraction. After each session the children were given the choice of which of the three tasks they wished to work on when the adult left the room for a few minutes. Tasks associated with verbal reprimands of off-task behavior were never chosen. The first and second choices were always the task associated with praise for on-task behavior or the task where the children were ignored. These preferences generalized to similar tasks. |
