ABBA counterbalancing involves alternating between the experimental condition and control condition, which may not be effective in balancing practice effects as participants may continue to improve across both conditions. Block randomization or Latin Square may be more effective in balancing practice effects as they distribute the conditions evenly across the experiment. All possible orders may also be effective, but it may be time-consuming and impractical for larger sample sizes.
