The aim of the present study was to analyze early vocalization development, the predictive value of this development in terms of later language skills, and possible gender difference in early vocalization development in a selected cohort of 32 very-low-birth-weight (VLBW) children and 35 full-term controls. The data on early vocalization development were gathered using a structured maternal report method. Language skills were assessed at 2.0. No significant difference was found between the groups in the rate of early vocalization development when corrected age was used for the VLBW children. The rate of early vocalization development correlated significantly with later language performance in VLBW children. Only weak correlations were detected in the control group. We found no gender difference in early vocalization development in either of the groups. The findings suggest that the rate of early vocalization development can be used as a clinical predictor of later linguistic performance in VLBW children. (Contains 1 figure and 5 tables.)
