Recovery of lost transfer effects.
Tracking tasks known to facilitate or interfere with one another were investigated under various sequences of alternation. Double and treble alternating sequences of 2 tasks were used. 6 groups of 12 Ss practiced for 20 10-sec. trials, with 50-sec. intertrial intervals. Trend analyses were employed in comparing the results of the double and treble alternating sequences with the single alternating sequence and postshift trials of the previous study (Laszlo & Pritchard, 1969). The results showed that facilitation or interference lost with single alternation was recovered with double or treble alternating sequences. Rate and degree of recovery appeared to depend upon the degree of transfer between tasks and strategies employed by S. These results were discussed in terms of motor program consolidation.
