Subclaims¶

q3 i? Response boundary showed within-day decreases in a majority of participants on each day, and between-day decreases mainly from day 1 to day 2, with only a minority decreasing at later day transitions. → Cochrane 2023

Point estimates from the best-fitting mixed-effects DDM (21 participants, 4 days) show heterogeneous response boundary dynamics: within-day decreases in 80.9%, 61.9%, 76.2%, and 55.1% of participants across the four days, and between-day decreases from day 1 to day 2 in 95.2% of participants. No effect size is printed.

"Within-day decreases in RB were present in most participants (80.9%, 61.9%, 76.2%, and 55.1% of participants, on each of the four days respectively). Between-day changes in RB were primarily decreasing from day 1 to day 2 (95.2% of participants)"
