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...

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.

Summary

This summary is machine-generated.

A phonological intervention program improved brain function in bilingual children with specific language impairment (SLI). This led to positive changes in auditory cortex activity, demonstrating neuroplasticity.

Background:

Specific Language Impairment (SLI) affects language development in children.
Bilingualism presents unique challenges and strengths in language acquisition.
Understanding neuroplasticity is crucial for effective language interventions.

Purpose of the Study:

To evaluate the impact of a phonological intervention on brain activity in bilingual children with SLI.
To investigate neuroplastic changes in auditory cortices following the intervention.
To compare the intervention's effects with a physical exercise control group.

Main Methods:

A phonological intervention program was delivered by preschool teachers to small groups.
A control group of children with SLI received a physical exercise program.
Auditory evoked magnetic fields were measured using an oddball paradigm before and after intervention, followed by a behavioral discrimination test.

Main Results:

The phonological intervention group showed significant improvements in brain activity.
Plastic changes were observed in the left and right auditory cortices.
These changes correlated with improved auditory discrimination abilities.

Conclusions:

Phonological intervention is effective in enhancing brain function in bilingual children with SLI.
The intervention promotes neuroplasticity in auditory processing areas.
Targeted phonological therapy can positively impact language development and neural pathways.
