Yes, it’s a good idea to read bedtime stories to your children, but for the development of language and literacy, it’s not enough. The question for me remains: is it something you can help your children with as this longitudinal study is showing a correlation rather than showing a clear causal relation:

• Self-regulation development was associated with language and literacy skills.
• Earlier self-regulation was associated with higher skills and earlier development.

From the press release:

Research from Michigan State University found that a child’s ability to self-regulate is a critical element in childhood language and literacy development, and that the earlier they can hone these skills, the faster language and literacy skills develop leading to better skills in the long run.

“Self-regulation is an umbrella term to define children’s abilities to keep information in their working memories, pay attention to tasks and even to inhibit behaviors that might prevent them from accomplishing tasks,” said Lori Skibbe, associate professor in the human development and family studies department and lead author of the study.

Through her research, Skibbe found that children who could self-regulate earlier had higher language and learning skills through at least second grade.

“We’ve known that there is a relationship between self-regulation and language and literacy, but our work shows that there is a lasting impact. The early advantage of self-regulation means children are learning these critical language and literacy skills earlier and faster, which sets the stage for developing additional skills earlier as well,” Skibbe said.

Skibbe and her research team assessed 351 children twice a year from preschool to second grade, on both self-regulation and on language and literacy.

When assessing self-regulation, the children were asked to play a game that required them to follow prompts from the researchers.

“We asked them to touch their heads, shoulders, knees and toes, similar to the childhood ‘Simon Says’ game,” Skibbe said. “Then, we reversed or mixed the commands to see who could follow based on the instructions they retained.”

When assessing academic development, Skibbe looked at four language and literacy skills: comprehension; vocabulary; early decoding, or the ability to identify letters of the alphabet and read short words; and phonological awareness, or understanding the sound structure of language.

Some children are biologically predisposed to develop self-regulation skills earlier, Skibbe said, but there are things parents can do to help them in their development.

“By nature, humans are not effective multitaskers, and children need time where they focus on only one thing,” she said.

“Parents need to be aware of how their children can regulate their own behavior based on what’s going on around them. Parents can structure their home environment and routines in ways that support children,” Skibbe said. A full night of sleep, playing games with children and having time without distractions in the background are things you might not think help language and literacy development, but they do.”

Abstract of the study:

Previous research has established that higher levels of behavioral self-regulation are associated with higher levels of language and literacy. In this study, we take a more developmental perspective by considering how trajectories of self-regulation development (early, intermediate, late) predict the way literacy and language skills develop from preschool through second grade. Children (n = 351) were assessed twice per year for up to four years on indicators of decoding, reading comprehension, phonological awareness, and vocabulary. Using non-linear growth curve models, we found that children who demonstrated self-regulation earlier had higher language and literacy skills throughout preschool to second grade. More specifically, earlier self-regulation trajectories were associated with both higher levels and earlier development of both decoding and reading comprehension, but not faster development. Children with early self-regulation trajectories developed phonological awareness earlier than those with late self-regulation trajectories. Finally, children with early self-regulation trajectories had higher levels of vocabulary than children with intermediate trajectories, but did not differ on the rate or timing of vocabulary development. Findings point to the enduring and interconnected nature of self-regulation and children’s language and literacy development.
