Directional Characteristics of Behavioral Change

Defining the response classes A (17 to 20 sec.) and B (27 to 30 sec.) in terms of within-chain delay, 80 4th-grade boys practiced mirror drawing. It was found that the behavioral change involved in learning B after learning A is different from that involved in learning A after learning B. The directional characteristics of this behavioral change are explained as partly due to the extra-experimental condition of the-faster-the-better reward contingency.
