Sauer, E., Levine, S. C., & Goldin-Meadow, S. (2010). Early Gesture Predicts Language Delay in Children With Pre- or Perinatal Brain Lesions. Child Development, 81(2), 528-539. doi:10.1111/j.1467-8624.2009.01413.x
The article I chose is looking at language differences in children with pre or perinatal brain lesions on gestures they use. Eleven children with perinatal brain lesions were used in this study. The lesions were either a result of cerebrovascular infarcts of the middle cerebral artery territory, primary affecting inferior frontal and superior temporal regions or the result of periventricular lesions , primarily affecting subcortical structures and white matter tracts. Eight girls and three boys were studied longitudinally between 18 months and 30 months. The children were categorized into two groups on whether the infant’s gestures at 18 months were within the or below the range of typically developing children. Previous studies have found that there are relations between vocabulary growth and early gestures. Children will begin communicating through gestures which overtime is replaced with speech. The results found that the children with perinatal lesions whose gestures was within the typical developing gesture range developed a productive vocabulary at 22 and 26 months and a receptive vocabulary at 30 months were all within the typical developing gesture range. Children with perinatal lesions who were below the typical gesture developing range did not develop a productive vocabulary at 22 and 26 months and did not develop a receptive vocabulary at 30 months. The researcher’s results found that gestures were an early indicator of which children would experience some type of language delay. Further research into gestures of children that have brain lesions may help predict early delays in language.
