•  Spelling accuracy grew as a function of number of exposures
(including test exposures), rather than training condition.
•  Even words in the control condition improved over test times.
•  Children with higher WRAT Spelling scores were more
accurate at all test times than children with lower scores (p<.
001).

•  Children with higher general vocabulary knowledge earned
higher scores during learning than children with lower
vocabulary knowledge (p=.05).
•  Group X Condition interaction approached significance (p=.075)
•  Higher vocabulary group showed similar performance across
conditions (p=.63). Lower vocabulary group had more difficulty
generating synonyms for words in the 4 Sentence condition
than in the 4 Word (p=.03) or Non-familiarized (p =.07)
conditions.

vocabulary knowledge influenced familiarity ratings (all p>.8).

•  Synonym matching scores for trained words increased across
test times (p<.001).
•  Significant Group X Test Time interaction (p<.001).
•  Children with higher general vocabulary knowledge showed
significantly greater growth than children with lower scores
(p =.005).
•  When groups were collapsed, performance for words in the 4
Sentence condition was marginally better than for the 4 Word
(p=.03) and Non-familiarized (p=.09) conditions. No significant
differences were observed in divided groups.
