Examining Early Vocabulary Growth Trajectories in Late Talkers in a Low-Income Longitudinal Sample.

ABSTRACT: Studies show children in low-income households have heightened risk of developing as late talkers (LTs). Scholars have attributed the cause of these differences to variability in child-directed and observed language input, parenting quality, attendance at childcare facilities, or some combination therein, as briefly reviewed. However, this study focuses on a sample entirely of families experiencing low income to explore differences within this group. This study explores growth trajectories for child vocabulary production from age 8-30 months in a racially-diverse low-income longitudinal sample in the U.S. (n = 199). Using multi-level multiple group models, we explore differences in growth trajectories for LTs and non-LT peers (identified: age 22-30 months) and identify the age at which voc
