q2 · i? · associational · r2

Regression analysis reported in the Results section: overall latency did not predict LDS average length of phrase at 36 months; the article states 'latency does not predict average length of phrase', while noting latency did predict TPVT.

"The results show that latency does predict TPVT both when collapsing across all trials and when looking at noun and verb trials separately, but latency does not predict average length of phrase."

q2 · i? · associational · r2

Exploratory verb-only regression in the Results: 'we did examine verb trials alone; no significant effect of latency was found' for average length of phrase, despite expectations that verb knowledge supports grammar.

"given that verb knowledge is expected to predict grammatical knowledge better than noun knowledge (Hadley et al., 2016), we did examine verb trials alone; no significant effect of latency was found."

Discussion¶

Related Claims¶

• Overall lexical processing latency at 36 months predicts receptive vocabulary at 60 months, but not over and above concurrent vocabulary — 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
• 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
• Lexical processing speed at 36 months is associated with concurrent receptive vocabulary, but more weakly than at younger ages — related
• Verb trials with dynamic scenes yield longer latencies than noun trials with static images, and noun and verb latencies are moderately correlated — related
• Faster processing speed at 19 months predicts faster syntactic growth between 19 and 30 months, controlling for concurrent vocabulary — related
