Shaping Faster Question Answering.
Brooks, Lloyd O.
To test a hypothesis that question answering speed and accuracy can be increased by an automated shaping procedure, a film, "The Analysis of Behavior," was presented individually by a teaching machine during twice-per-week sessions to one high school student and 12 junior college students. Six of the students were informed of monetary rewards for increasing speed as well as accuracy in each of their responses to questions on seven sets of the film while the remaining seven students were informed of monetary rewards for response accuracy only. Student responses to multiple presentations of each set were scored for accuracy (the control condition) and, half of the time, for speed as well (the experimental condition) by a machine providing immediate reinforcement. When frames of the experimental condition responses were compared with frames of the control condition, it was found that scoring and reinforcing for speed were statistically reliable in increasing both speed and accuracy; a statistically significant relationship exists between the number of reinforcements and question answering accuracy and speed. In addition, results showed that instructions could increase performance in periods of infrequent reinforcement. (SP)
