Number of Amblyopic Subjects Trained on and Approximate Number of Trials Completed for Each Task, along with the Number of Runs Completed and Duration of Each Training Session

Trained Task	Amblyopic Subjects Trained (n)	Trials (∼n)	Runs of Test per Training Session	Approximate Time per Training Session (min)
Letter acuity	5	2000	5	10
Letter contrast	10	3795	5	20
Grating acuity	8	3300	5	20
Grating contrast	6	4200	1	30

The number of trials per run and the duration of each training session were dependent on the performance and termination criteria of each test.
