The mean number of valid trials acquired on the gap-overlap paradigm differed between sites at 10 months ( F( 335) = 2.61, p = .035, ηp 2 = 0.03), with marginal significance at 5 months ( F (193) = 2.92, p = .056, ηp 2 = 0.03) and not at 14 months ( F (322) = 1.27, p = .28, ηp 2 = 0.02); broadly Site D had more valid trials than other sites.
A chi-squared test on the number of parents with primary/ secondary (education to 16 years) vs tertiary education revealed marginally significant site effects ( χ 2 = 6.52, p = 0.09), though given the size of the sample the differences were not pronounced.
