Subclaims¶

q2 i? The main effect of lexical processing on BSRA at 60 months did not remain when TPVT at 36 months was added as a predictor. → Koenig Ashley 2020 q2 i? Lexical processing but not TPVT at 60 months predicted BSRA scores, suggesting lexical processing at 36 months is a better measure of later school readiness than vocabulary size at 60 months. → Koenig Ashley 2020 (2)

q2 · i? · associational · r2

Regression adding TPVT at 36 months to the BSRA models: 'the main effect of lexical processing did not remain when TPVT at 36 months was added as a predictor', so latency added no prediction over concurrent vocabulary.

"However, the main effect of lexical processing did not remain when TPVT at 36 months was added as a predictor. That is, lexical processing did not predict later BSRA scores over and above TPVT at 36 months."

q2 · i? · associational · r2

Comparison of predictors in the BSRA models: 'lexical processing but not TPVT at 60 months predicted BSRA scores', which the authors read as lexical processing at 36 months being 'a better measure of later school readiness'.

"Interestingly, lexical processing but not TPVT at 60 months predicted BSRA scores, indicating that lexical processing at 36 months is a better measure of later school readiness than is vocabulary size at 60 months."
