ANALYSIS OF CHUNKING 2: SEQUENCE BOUNDARY INTERVAL SD (Days 10-17)

NARRATIVE RESULTS

Results show that there was not an overall significant change in sequence boundary interval variability as training progressed: F(7,98) = 1.428, p = 0.203. There was no significant day * age
interaction, suggesting that change was similar in both groups: F(7,98) = 1.223, p = 0.297. However, a strongly significant between subjects effect indicated that both groups displayed different
variability levels (F(1,14) = 8.855, p = 0.01).
