q3 i2 Observing congruent perturbations decreased error (d = -0.5 to -5.07, overall d = -1.71); observing incongruent perturbations increased error (d = 0.55 to 3.36, overall 1.19). → Julian Rudisch 2024

Review synthesis contrasting congruent versus incongruent observational practice against control groups across the included studies, with forest plots in Fig. 2. Nine studies showed reduced error after congruent observation; eight showed increased error after incongruent observation.

"The effect sizes for direct learning effects from observational practice from congruent stimuli ranged from d = −0.5 to d = −5.07, with an overall effect size of d= −1.71, indicating an error reductionas compared to a control group. As opposed to that, effect sizes for incongruent stimuli ranged from d = 0.55 to d = 3.36 with an overall effect size of 1.19, showing an error increase."
