An ANOVA of the gain scores showed a significantly greater change in the ROR
group than in the control group parents reading to their children (F = 2.69,
df = 1,21, p = .10). At 6 months, 50% of ROR parents said they read children’s
books to their infants. By 12 months this increased to 93% of ROR parents reading.
By comparison, 78% of control parents read to their children at 6 months, increasing
to 89% at 12 months. This is illustrated in Figure 1. In other words, at 6 months
more parents in the control group were reading to their infants, but by 12 months
this pattern had reversed: a greater proportion of ROR parents read to their
children.
