Insights

Very low birth weight preterm infants show delayed cognitive and expressive language development compared to term infants. These delays persist beyond infancy, highlighting the need for early intervention.

Area of Science:

  • Developmental Pediatrics
  • Neuroscience
  • Speech-Language Pathology

Background:

  • Very low birth weight (VLBW) preterm infants are at risk for developmental delays.
  • Cognitive and expressive language development are crucial areas affected by preterm birth.

Purpose of the Study:

  • To compare the cognitive and expressive language development of VLBW preterm infants with term infants.
  • To identify the developmental trajectory and timing of delays in VLBW infants.

Main Methods:

  • Longitudinal study involving monthly evaluations of 12 VLBW preterm infants and 20 term infants.
  • Utilized the Protocol for Expressive Language and Cognition Development Observation (PELCDO).
  • Videotaped sessions and analyzed data according to the PELCDO protocol.

Main Results:

  • VLBW preterm infants demonstrated significantly later development in cognition and expressive language compared to term infants.
  • Positive correlations were observed between cognitive and expressive language development.
  • Developmental delays became more pronounced after 6 months of age, extending through the sensorimotor and into the preoperational periods.

Conclusions:

  • Cognitive and expressive language delays are significant in VLBW preterm infants.
  • Continuous follow-up evaluations are essential for these infants.
  • Identifying the optimal timing for speech-language intervention is crucial for addressing these developmental needs.

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
