5	10/10	17	57.14	64.67	[−0.26, 2.70]
Low responders
6	4/15	66	38.60	54.89	[0.09, 2.03]
7	3/10	29	58.14	41.17	[−2.84, −0.29]
8	3/15	60	56.36	52.89	[−1.25, 0.53]

10	0/5	11	55.67	46.67	[−2.47, 0.91]

Note. Children 1 and 3 had a three-choice array; Child 6 had three choices in baseline for the first set and a three-choice array thereafter; the remaining children had a two-choice array throughout the study. CI = confidence interval.

^aWords learned indicates the number of words meeting the 80% correct criterion on receptive probes.
