This study shows that home literacy activities contribute to kindergarten children's higher-level comprehension processes, namely knowledge integration and knowledge access. Kindergarten children completed measures assessing literacy and language skills and then their performances on these measures were correlated with home literacy activities, which were assessed via a parental questionnaire. Consistent with previous research, the results revealed that informal home literacy activities were positively related to language comprehension and vocabulary but not to letter-word decoding and phonemic decoding skills. The results also revealed that home literacy activities were positively related to knowledge integration and knowledge access, two strong predictors of language and reading comprehension. Finally, the present results suggest that the contributions that home literacy activities make to language comprehension are the same contributions that home literacy activities make to higher-level comprehension processes. In other words, the contributions that home literacy activities make to language comprehension are not independent of the contributions that home literacy activities make to higher-level comprehension processes.
