Language Development

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...

Language and Cognition

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.

Lateralization

Lateralization

Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Learning Disabilities

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.

Biological Influences on Intelligence

Biological 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...

Higher Mental Functions of the Brain: Language

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...

Summary

Early language delay in toddlers can persist to age 3. Poor phonetic skills at 28 months predict later expressive language difficulties, highlighting the need for early identification and intervention for late talkers (LTs).

Area of Science:

Developmental Psychology
Linguistics
Pediatrics

Background:

Late talkers (LTs) may experience persistent language delays.
Understanding the trajectory of language development in LTs is crucial.

Purpose of the Study:

To examine language skill continuity and directionality in LTs.
To identify predictors of language outcomes at 3 years.

Main Methods:

Longitudinal study of 23 LTs and 24 typically developing peers (TDs).
Linguistic assessments at 28, 32, and 36 months (vocabulary, MLU, consonants).
Analysis of familial history of otitis media.

Main Results:

LTs exhibited a consistent language lag compared to TDs.
Poor phonetic inventories at 28 months predicted lower MLU at 32 and 36 months.
Phonetic deficits at 28 months predicted expressive vocabulary at 32 months.

Conclusions:

Early language delay negatively impacts language skills up to age 3.
Poor phonetic inventories are a significant predictor of later language outcomes.
Further research with sensitive tools is needed for assessing language development.
