Investigation of Procedures to Control Variability of Response Latency in Paired-Associate Overlearning.
Judd, Wilson A.; Glaser, Robert
Research in paired-associate overlearning sought means of decreasing the variability while maintaining the magnitude of the decrement in stimulus-response latency (SRL). SRL was divided into decision latency (DL) and manual response latency (MRL); it was hypothesized that self-pacing of inter-item intervals would reduce V. Group I received stimuli at fixed intervals after each response group II controlled the intervals. Practice continued for 16 trials after the trial of last error (TLE). Self-pacing reduced the variability of SRL, but also reduced the post-TLE decrement by teaching fast responses in practice. The task was altered to increase pre-TLE for group III. Pre-TLE SRL of group III equaled that of group I, but post TLE did not. Self-pacing slightly reduced the variability of SRL, but DL was no less variable than SRL, and post-TLE decrement in DL was less than in SRL. It was concluded that: 1) it was unnecessary to shape fast responses during practice; 2) self-pacing decreased the variability of SRL; 3) the attempt to reduce variability by measuring DL was unsuccessful; and 4) the process underlying post-TLE SRL decrease influenced both DL and SRL.
