Language and Cognition

416
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.

Language Development01:22

Language Development

437
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...

Lateralization01:28

Lateralization

408
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.

Higher Mental Functions of the Brain: Language

995
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 Language01:24

Components of Language

370
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.

Time-Domain Interpretation of PD Control01:07

Time-Domain Interpretation of PD Control

168
Proportional-Derivative (PD) control is a widely used control method in various engineering systems to enhance stability and performance. In a system with only proportional control, common issues include high maximum overshoot and oscillation, observed in both the error signal and its rate of change. This behavior can be divided into three distinct phases: initial overshoot, subsequent undershoot, and gradual stabilization.
Consider the example of control of motor torque. Initially, a positive...

Summary

Bilinguals control language interference by inhibiting the non-target language. This study found that this inhibition occurs only once per word, not repeatedly, aiding efficient language switching.

Area of Science:

  • Psycholinguistics
  • Cognitive Neuroscience
  • Bilingualism Research

Background:

  • Bilingual individuals must manage interference from their non-target language to prevent errors.
  • Understanding the mechanisms of language control in bilinguals is crucial for explaining cognitive processes during speech production.

Purpose of the Study:

  • To investigate the frequency and nature of language control mechanisms in bilinguals operating in a dual-language mode.
  • To determine if language control is applied continuously or only upon the initial instance of a word or language switch.

Main Methods:

  • Three groups of Spanish-English bilinguals performed picture naming tasks, alternating between dominant and non-dominant languages.
  • A control group consistently named pictures in their dominant language.
  • Naming latencies in the dominant language were analyzed following non-dominant language naming to assess control aftereffects.

Main Results:

  • The number of non-dominant language naming trials did not significantly impact subsequent dominant language naming latencies.
  • This lack of effect was observed despite sufficient statistical power to detect potential inhibition aftereffects.
  • No evidence was found to support continuous inhibition of the non-target language during repeated naming.

Conclusions:

  • Bilingual language control, including inhibitory mechanisms, is primarily applied once per word translation upon its first use.
  • Control is not continuously reapplied with subsequent repetitions of the same word or language.
  • These findings suggest an efficient, non-repetitive control strategy in dual-language processing.
