Insights

Very low birthweight infants often experience language and visuomotor delays. Infants who are small for their gestational age face a higher risk of these developmental delays at two years corrected age.

Area of Science:

  • Neonatal development
  • Pediatric neurology
  • Developmental pediatrics

Background:

  • Very low birthweight (VLBW) infants are at increased risk for developmental delays.
  • Early identification of language and visuomotor delays is crucial for timely intervention.
  • Understanding predictors of these delays can inform targeted support strategies.

Purpose of the Study:

  • To determine the prevalence of language and visuomotor delay in VLBW children at 2 years corrected age.
  • To identify predictors associated with these developmental delays.
  • To assess the relationship between birth characteristics and developmental outcomes.

Main Methods:

  • Prospective observational study of 164 VLBW infants (birthweight ≤1250 g).
  • Developmental assessment at 2 years corrected age using Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS).
  • Calculation of Development Quotient (DQ) and analysis of predictors.

Main Results:

  • 24% of VLBW children exhibited below-average Development Quotient (DQ) at 2 years corrected age.
  • Infants born small for gestational age (SGA) showed a significantly higher risk of below-average DQ (P=0.036).
  • Gestational age and socioeconomic status correlated positively with language development at 9 months and 2 years, respectively.

Conclusions:

  • The prevalence of language and visuomotor delay is high in VLBW infants.
  • Small for gestational age status is a significant predictor of increased risk for developmental delays in VLBW children.
  • Early developmental screening and targeted interventions are essential for VLBW populations.

Language and Cognition01:27

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Language Development01:22

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...

Piaget's Stage 1 of Cognitive Development

The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

Piaget's Stage 2 of Cognitive Development

The preoperational stage, the second of Jean Piaget's four stages of cognitive development, spans approximately ages 2 to 7 and is characterized by the emergence of symbolic thinking. During this stage, children use language, images, and symbols to represent objects and concepts, enabling them to engage in imaginative and pretend play. This symbolic thinking supports children's ability to perform make-believe actions, such as imagining a broom as a horse or their hand as a phone, blending...

The Nativist Approach01:21

The Nativist Approach

The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
