Table 2. Use of Internal Computational Parameters to Predict Developmental Outcomes (Persisting Delay, Resolving Delay) in a Polygenic Model of Language Delay.

Computational parameter	Processing role	Effect size of PD versus RD comparison
Note. PD = persisting delay; RD = resolving delay. Scores show ηp2 effect sizes from ANOVA comparing PD and RD groups (see Thomas & Knowland, 2014, Table 2, for parallel analyses using logistic regression methods).
