Language and Cognition01:27

Language and Cognition

411
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.

Higher Mental Functions of the Brain: Language01:10

Higher Mental Functions of the Brain: Language

973
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...

Lateralization01:28

Lateralization

393
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.

Language Development01:22

Language Development

426
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...

Higher Mental Functions of Brain: Learning and Memory

934
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Neuroplasticity01:01

Neuroplasticity

681
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Linguistics

Background:

  • Individual differences in language processing are well-documented.
  • The neural underpinnings of these variations, particularly white matter connectivity, remain largely unexplored.

Purpose of the Study:

  • To investigate the relationship between white matter structural connectivity and the ability to process syntactically complex sentences.
  • To examine how this relationship is affected by multiday language training.

Main Methods:

  • Diffusion tractography was used to map long-range white matter connectivity.
  • Singular value decomposition identified network motifs correlating with language performance.
  • Analysis examined both baseline connectivity and changes following training.

Main Results:

  • Two specific white matter network motifs (left and right hemisphere) significantly predicted individual language processing performance.
  • A distinct left hemispheric motif's change over training correlated with performance improvement, indicating neural plasticity.
  • These networks involve areas associated with working memory and motor functions, not exclusively classical language regions.

Conclusions:

  • Individual differences in white matter structure contribute to variations in language processing and learning.
  • Brain structural connectivity, particularly involving working memory networks, may be a key factor in cognitive abilities.
  • Training-induced plasticity in white matter networks supports language learning.
