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? Latency in a lexical processing task at 36 months correlated with concurrent receptive vocabulary, but the association was weaker than the −0.60 correlation reported for 25-month-olds. → Koenig Ashley 2020

Correlation reported in the Discussion of this study of 36-month-olds: the authors report their concurrent latency–vocabulary association, 'a correlation of only −0.27', contrasting it with the −0.60 correlation Fernald et al. (2006) reported for 25-month-olds on the PPVT.
"Fernald et al. (2006) report that 25-month-olds showed a correlation of −0.60 between latency in their lexical processing task and receptive vocabulary scores on the PPVT, while we found a correlation of only −0.27."

Learner Variables¶
- Processing Speed — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Lexical processing latency at 36 months does not predict concurrent grammatical complexity (LDS average length of phrase) — related
- Lexical processing latency at 36 months predicts school readiness (BSRA) at 60 months for overall and noun-trial latency, but not verb-trial latency — related
- Overall lexical processing latency at 36 months predicts receptive vocabulary at 60 months, but not over and above concurrent vocabulary — related
- Lexical processing at 36 months did not predict later school readiness over and above concurrent vocabulary, but predicted BSRA better than vocabulary at 60 months did — related
- Verb trials with dynamic scenes yield longer latencies than noun trials with static images, and noun and verb latencies are moderately correlated — related
- Processing speed at 19 months correlates with expressive vocabulary between 18 and 31 months, but processing speed at 25 and 31 months does not — related
