Higher Mental Functions of the Brain: Language

1.0K
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 and Cognition

431
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.

Encoding01:19

Encoding

241
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

Lateralization01:28

Lateralization

437
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.

Concepts and Prototypes01:24

Concepts and Prototypes

216
The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Components of Language01:24

Components of Language

382
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.

Summary

Morphemes are processed at the morpho-orthographic level during handwriting, acting as grouping units. This process in written word production is independent of word meaning, as shown by priming experiments.

Area of Science:

  • Psycholinguistics
  • Cognitive Neuroscience
  • Computational Linguistics

Background:

  • Written word production involves complex central and peripheral processes.
  • Morphological units in the lexicon are known to influence handwriting dynamics.
  • Understanding morphological representation is key to explaining written word production.

Purpose of the Study:

  • To investigate the representation level of morphological information in the French lexicon during written word production.
  • To differentiate between morpho-orthographic and morpho-semantic processing using pseudo-derived primes.
  • To examine the influence of morphological priming on handwriting dynamics.

Main Methods:

  • Two priming experiments were conducted using derived, pseudo-derived, and unrelated primes.
  • Experiment 1 utilized a learning-recall task measuring writing latency and duration.
  • Experiment 2 employed a word pair copying task measuring inter-word and writing duration.

Main Results:

  • Morphological priming effects were observed in both experiments.
  • Priming influenced writing latency in Experiment 1 and writing duration in Experiment 2.
  • Similar priming patterns were found for derived and pseudo-derived conditions, suggesting morpho-orthographic processing.

Conclusions:

  • Morphemes are processed at the morpho-orthographic representation level during written word production.
  • Morphemes function as grouping units in handwriting.
  • This grouping process operates independently of the morphemes' semantic meaning.
