Subclaims¶

q3 i? Serial order reconstruction performance at Age 4 accounted for significant variance in vocabulary at Age 5 after controlling for age, nonverbal reasoning and initial vocabulary (12% of variance), and a further 7% of independent variance once variance shared with nonword repetition was removed. → Leclercq 2010

Leclercq 2010¶

q3 · i? · associational · r2

Hierarchical multiple regression in the longitudinal study of 60 children tested at Age 4 and Age 5, predicting Age 5 vocabulary from Age 4 STM measures. The article reports "nonword repetition accounted for 8 % of variance and serial order reconstruction accounted for 12 % of variance".

"We observed that performances on both the serial order reconstruction task and on the nonword delayed repetition task at Age 4 accounted for significant parts of variance in vocabulary scores after controlling for age, nonverbal reasoning and initial vocabulary knowledge (nonword repetition accounted for 8 % of variance and serial order reconstruction accounted for 12 % of variance)."

q3 · i? · associational · r2

Same longitudinal regression set: when entered after the nonword task, the serial order task explained "a further 7 % of independent variance in vocabulary scores", whereas the nonword task added none when entered after serial order STM.

"Furthermore, scores at the serial order reconstruction task accounted for a further 7 % of independent variance in vocabulary scores once the variance shared with nonword repetition abilities was removed, while the reverse was not true (Table 6)."

Discussion¶

Related Claims¶

• Serial order STM at Age 4 predicts later nonverbal reasoning, but serial order STM gain does not predict nonverbal reasoning gain
• Growth in serial order STM from Age 4 to Age 5 predicts growth in vocabulary, whereas growth in item STM does not — related
• Vocabulary knowledge at Age 4 does not predict serial order STM development at Age 5 once initial age, nonverbal reasoning and serial order STM are controlled — related
• Serial order STM shows raw concurrent and longitudinal correlations with vocabulary at both ages — related
