T tests did not show any difference in standard PPVT-R scores between the high- and low-engagement-of-reflection groups, t < 1, but indicated that the group with a high level of need for reflection had significantly lower standard PPVT-R scores than the group with a low level of need for reflection, r(107) = 2.
T tests did not reveal any difference in standard PPVT-R scores between the high-insight and the low-insight groups, t < 1.

The predictors of warmth and positive verbal exchanges were significant when predicting 30-month Stanford Binet and 44-month PPVT-R scores, even after demographic risk index factors (conditions of low income, low education, minority status, and absence of male partner) were taken into account (Hann, Osofsky, & Culp, 1996).
To determine the degree to which random assignment was successful in forming comparable groups, one-way analyses of variance (ANOVAs) were performed on the McCarthy GCI, PPVT-R, TELD, and TERA pretests.
