Mean Difference Scores for each Semantic Category within each Phonotactic Probability/Neighborhood Density Condition in Experiment 2

1 Phonotactic Probability Effect: Rare > Common 2 Neighborhood Density Effect: Sparse > Dense
All Ages, Collapsed Across both Times 5-year-olds at immediate time point
Dense = No Sparse = Yes Common = No Rare = Yes
Toys .02 .13 −.07 .26
Horns −.03 .06 .06 .13
Candy .18 .10 −.07 .13
Pets −.15 .04 −.09 .07
All Items −.02 .06 −.04 .15

Note:

1

Phonotactic Probability Effect: Difference scores were calculated for semantic categories by subtracting the accuracy for common nonwords from the accuracy for rare nonwords collapsed across both time points for all ages. Positive difference scores for sparse nonwords indicate that the item data converged with the participant analysis (i.e., Rare > Common for sparse nonwords).

2

Neighborhood Density Effect: Difference scores were calculated for semantic categories by subtracting the accuracy for dense nonwords from the accuracy for sparse nonwords only at the immediate time point and only for 5-year-olds. Positive difference score for rare sound sequences indicates that the item data converged with the participant analysis (i.e., Sparse > Dense, for rare sound sequences at the immediate time point for 5-year-olds).
