Illustrates the exemplar "wug" and the distracter that were used during the 10 trials. Remaining stimuli were used during the generalization trials and varied by shape, color, and texture as illustrated above.

Predicted proportions of CI and Hearing children meeting criterion by age and parenting behavior.
Compares acquisition of symbolic play and noun classification by hearing status, age at implantation, and maternal sensitivity and linguistic stimulation. The top panel illustrates symbolic play, the middle panel illustrates noun classification, and the bottom panel illustrates language age. Estimated Survival Functions. A) Symbolic Play by hearing status; B) Symbolic Play by implantation age; C) Symbolic Play by Parent Behavior; D) Noun Classification by hearing status; E) Noun Classification by implantation age; F) Noun Classification by parent behavior; G) Language Age by hearing status; H) Language Age by implantation age; I) Language Age by parent behavior. Delays represent the difference in adjusted median survival times with the NH cohort as the reference group.
