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.
q3 i? Reaction time to shift gaze from distracter to target decreased significantly with age across the three measurement points. → Michelle S. Peter 2019

Michelle S. Peter, Samantha Durrant, Andrew Jessop, Amy Bidgood, Julian M. Pine, Caroline F. Rowland. (2019). Does speed of processing or vocabulary size predict later language growth in toddlers? Cognitive Psychology 115 (2019) 101238. https://doi.org/10.1016/j.cogpsych.2019.101238
q3 · i? · associational · r2
Mixed effects model on reaction time at 19, 25 and 31 months in the Language 0–5 cohort, with Measurement point as fixed effect and random slope for Participant. Mean RT fell from 729.94 ms at 19 months to 639.14 ms at 31 months, and the model showed "a main effect of Measurement point".
"The results revealed a main effect of Measurement point (β=−8.32, χ2(1)=49.71, p < .001), indicating that children got faster at recognising familiar words in speech with age."
Discussion¶
Related Claims¶
- Individual differences in processing speed remain broadly stable between 19 and 31 months — related
- Processing speed at 19 months does not significantly influence linear vocabulary growth between 19 and 30 months — related
- Children's vocabulary and reaction time improved significantly from 18 to 24 months, and maternal talk measures were highly intercorrelated — related
- Faster word recognition at 24 months is associated with larger vocabularies and greater vocabulary gains in Spanish-learning children — related
- Faster processing speed at 19 months predicts faster syntactic growth between 19 and 30 months, controlling for concurrent vocabulary — related
