Pamela C. Snow. (2021). Psychosocial Adversity in Early Childhood and Language and Literacy Skills in Adolescence: The Role of Speech-Language Pathology in Prevention, Policy, and Practice. Perspectives of the ASHA Special Interest Groups. https://doi.org/10.1044/2020_PERSP-20-00120

q2 · i? · review · r2

The review attributes the Matthew effect to Stanovich (2009) and notes it has also been described for mid-elementary reading ability and vocabulary growth (Duff et al., 2015). Children's own reading promotes Tier 2 and 3 vocabulary via text exposure.

"When children do not successfully make the transition to literacy in the first 3 years of school, this creates a Matthew effect, whereby students who may start only narrowly behind fall disproportionately further behind their more able age-matched peers over time"
