Subclaims¶

q2 i? Overall latency predicted TPVT at 60 months, but neither noun-only nor verb-only latency was a significant predictor. → Koenig Ashley 2020 q2 i? Overall latency was no longer a significant predictor of TPVT at 60 months once TPVT at 36 months was added to the model. → Koenig Ashley 2020 (2)

Regression in the Results of this longitudinal study: 'Overall latency predicted TPVT at 60 months', but in follow-up analyses of noun and verb trials separately 'neither showed that latency was a significant predictor'.

"Overall latency predicted TPVT at 60 months. We therefore followed this analysis with individual analyses for only noun trials and only verb trials, but neither showed that latency was a significant predictor of TPVT at 60 months."

q2 · i? · associational · r2

Regression adding TPVT at 36 months to the model: overall latency 'no longer is a significant predictor of TPVT at 60 months', and TPVT at 36 months itself was not significant (r(106) = 0.18, p = 0.053).

"The results indicate that overall latency no longer is a significant predictor of TPVT at 60 months. However, TPVT at 36 months also does not predict TPVT at 60 months (r(106) = 0.18, p = 0.053)."

Discussion¶

Related Claims¶

• 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 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
• 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
