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.

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...

Components of Language

Components of Language

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs. “eh”). Phonemes combine to...

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.

Cerebral Hemispheres

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

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...

Neuroimaging

Background:

The brain's capacity for abstract computation and generalization across different linguistic inputs is a central question.
Language transformations, like pluralization, vary across languages, raising questions about language-specific versus abstract neural processing.

Purpose of the Study:

To investigate the neural dynamics of grammatical word-form transformations in bilinguals.
To determine if grammatical computations generalize across languages and different surface forms.

Main Methods:

Magnetoencephalography (MEG) was used to track millisecond neural dynamics during phrase completion in Spanish-English bilinguals.
A design orthogonalizing semantic number, phonological changes, grammatical inflection, and language was employed.
Multivariate decoding analyzed neural patterns for abstract grammatical computations.

Main Results:

Grammatical transformations engaged a left-lateralized fronto-temporal network around 100 ms after cue onset.
Neural patterns for these computations generalized across languages, plural forms, and pseudowords.
This demonstrates abstractly equivalent operations are processed by shared neural substrates.

Conclusions:

The brain employs language-general computational mechanisms for grammatical transformations.
Grammatical transformations are implemented as abstract, generative operations.
Bilingualism provides insights into how abstract computations are shared across representational systems.
