Type	Input parameters			Output
	Assumed effect size of the treatment effect (partial η2)	α	Assumed power (1 − β)
(1) A priori power analysis	0.542†	0.05	0.95	Total N required = 12
(2) Post hoc power analysis in cohort	Observed effect size of the treatment effect (partial η2)		Total N
(a) Old	0.185	0.05	28	Achieved power = 0.911
(b) Young	0.053	0.05	34	Achieved power = 0.377

^†The assumed effect size in (1) was based on the results from the Group (WT versus rd/rd cl) × Visual Context (Same Context versus Context Change) between-subjects ANOVA in ref. 29. Data can be obtained from ref. 29.
