Behavioural data showing recall on four CVLT subscales across batteries and groups. Four selected subscales of the CVLT demonstrating delayed six-week memory facilitation for Group A (heavy line, filled squares). Horizontal bars represent 6-week learning blocks for Group A (grey bar) and Group B (white bar). A) Word recall on Trial 1, showing significant increase in recall for ote A relative to Group B (thin line, empty squares) at Battery 3. B) Short Delay Cued Recall for Group A and Group B, also exhibiting significant improvement at Battery 3. C) Long Delay Free Recall for Group A and Group B, showing the same pattern of delayed facilitation at Battery 3. D) Proactive Interference for the two groups, showing a significant decrease in interference for Group A at Battery 3. This pattern of delayed enhancement of memory was also found for Trial 5, Total Trials 1-5, Semantic Clustering and Subjective Clustering (not shown).
