The Scottish low birthweight study: II. Language attainment, cognitive status, and behavioural problems
Archives of Disease in Childhood
|June 1, 1992
Summary
Children born with low birth weight (<1750g) showed developmental delays in language, cognition, and behavior. Specific learning difficulties and attention problems were prevalent, highlighting the need for early intervention.
Area of Science:
- Child Development
- Neonatal Medicine
- Neuroscience
Background:
- Premature birth and low birth weight are significant risk factors for developmental challenges.
- Understanding long-term outcomes in this vulnerable population is crucial for public health.
Purpose of the Study:
- To assess the prevalence of language, cognitive, and behavioral problems in children born with low birth weight.
- To identify factors influencing developmental outcomes in this cohort.
Main Methods:
- Longitudinal study of 611 survivors born in Scotland in 1984 weighing less than 1750g.
- Assessment at 4.5 years using British Ability Scales for language, cognitive, and behavioral evaluations.
Main Results:
- Language comprehension correlated with birth weight, gestational age, and social class.
- Mean intelligence quotient (IQ) was 92.9 (14.7); poor performance noted in visual recognition, verbal comprehension, and number skills.
- 47% exhibited poor attention spans; increased behavioral problems reported compared to siblings.
Conclusions:
- Low birth weight is associated with a higher prevalence of developmental and behavioral issues.
- Specific learning difficulties may exist even in children with normal IQs.
- Early identification and support are vital for children born with low birth weight.

01:22Language 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...

01:27Language 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.
01:30Biological Influences on Intelligence
Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter more...
01:29Environmental Influences on Intelligence
Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children from...
01:30Information Processing Approach
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...
01:25Learning Disabilities
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
