TABLE 2.

Summary of blocked and orthogonal results based on the criterion cut-off of 10 % mean generalization accuracy in coding yes/no generalization (Elbert et al., 1984), the rank procedure for replicated AB design (Marascuilo & Serlin, 1988), and effect size for single-subject design (Beeson & Robey, 2006)

Frequent	22%	Yes	7/8	0.03	9.01
Infrequent	28%	Yes	5/7	0.16	8.35
Orthogonal
Dense–Freq	30%	Yes	5/5	0.03	14.83
Dense–Infreq	41%	Yes	2/32		11.39
Sparse–Freq	4%	No	2/32		3.19
Sparse–Infreq	17%	Yes	3/42		5.311

¹n=Number of factors evidencing positive gain; N=Number of possible factors examined for positive gain (i.e. number of subject × treated and untreated sounds from the same and different manner classes; see Morrisette & Gierut, 2002: 150).

²Inadequate power due to the number of factors evidencing positive gain by children enrolled in these conditions.
