Insights

Very-low-birth-weight infants often experience cognitive and language delays. This study found these delays are likely part of a global deficit, not specific auditory processing issues.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Pediatrics

Background:

  • Infants born very-low-birth-weight (VLBW) face higher risks for cognitive and language impairments.
  • Understanding the mechanisms behind these developmental deficits is crucial due to rising prematurity rates.

Purpose of the Study:

  • To investigate language and cognitive abilities in VLBW infants compared to normal birth-weight infants.
  • To determine if performance differences stem from global cognitive deficits or specific processing impairments.

Main Methods:

  • Thirty-two VLBW and 32 normal birth-weight infants participated.
  • Utilized visual and auditory-visual habituation recognition-memory tasks.
  • Administered standardized language and cognitive assessments.

Main Results:

  • VLBW infants demonstrated poorer performance on visual and auditory-visual habituation tasks.
  • VLBW infants scored significantly lower on both cognitive and language measures compared to controls.

Conclusions:

  • Language differences in VLBW children appear linked to broader cognitive functioning deficits.
  • Findings suggest a global impact on cognitive development rather than isolated rapid auditory processing impairments.

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...
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 exist...
Information Processing Approach01:30

Information 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...
Higher Mental Functions of the Brain: Language01:10

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...
Learning Disabilities01:25

Learning 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.
