Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Measures of maternal talk at 18 months were significantly correlated with children's reaction time at 24 months, accounting for 18–26% of the variance, and children of more talkative mothers had significantly faster mean RTs. → Hurtado Nereyda 2008

q2 · i? · associational · r2
Median-split analysis of the same 27-dyad longitudinal sample: mothers divided by word tokens produced at 18 months, children's RT measured with the looking-while-listening eye-tracking procedure at 24 months. Children of more talkative mothers were "significantly faster mean RTs, than did children with less talkative mothers, t(25) = 3.5, p < .01"; Table 3 shows maternal talk measures correlated with 24-month RT, accounting for 18–26% of variance.
"As shown in Figures 1 and 2, those children whose mothers produced more words shifted from the distracter to the target picture sooner, resulting in significantly faster mean RTs, than did children with less talkative mothers, t(25) = 3.5, p < .01."
Discussion¶
Related Claims¶
- Maternal talk quantity at 18 months predicts Spanish-learning children's vocabulary size and vocabulary gains at 24 months, controlling for earlier vocabulary — related
- Children's vocabulary and reaction time improved significantly from 18 to 24 months, and maternal talk measures were highly intercorrelated — related
- Maternal talk influences on vocabulary and processing speed are largely overlapping, with each mediating the other's relation to input — related
- Faster word recognition at 24 months is associated with larger vocabularies and greater vocabulary gains in Spanish-learning children — related
- Substantial variability in maternal talk existed within this primarily low-SES sample, and maternal talk was uncorrelated with SES — related
