In a 5-year longitudinal study of typical literacy development (Grades 1-5 or 3-7), relationships were examined between (a) parental responses to questionnaires about home literacy activities and ratings of children's self-regulation at home, both completed annually by the same parent, and (b) children's reading and writing achievement assessed annually at the university. Higher reading and writing achievement correlated with engaging in more home literacy activities. Parental help or monitoring of home literacy activities was greater for low-achieving than for high-achieving readers or writers. Children engaged more minutes per week in reading than writing activities at home, but parents provided more help with writing and reported computers were used more for homework than for school literacy instruction. Parental ratings of self-regulation of attention remained stable, but executive functions--goal-setting, hyperactivity, and impulsivity--tended to improve. Results are translated into consultation tips for literacy learning and best professional practices.
