Language and Cognition01:27

Language and Cognition

526
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.

Lateralization01:28

Lateralization

684
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

2.2K
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 Development01:22

Language Development

593
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...

Working Memory01:24

Working Memory

508
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

714
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

Area of Science:

  • Cognitive Neuroscience
  • Psycholinguistics
  • Second Language Acquisition

Background:

  • Previous studies linked language control and executive control in proficient bilinguals.
  • The impact of early language learning on this relationship remains under-explored.

Purpose of the Study:

  • To investigate how learning new languages affects executive control at the initial stages.
  • To examine the influence of switching between two newly acquired languages on cognitive functions.

Main Methods:

  • Trained Chinese speakers in German and Japanese, languages with no prior exposure.
  • Measured electrophysiological data (N2 and P3 amplitudes) using a flanker task before and after training.
  • Compared brain activity during language switching versus single-language tasks.

Main Results:

  • Behavioral data showed no significant language switching effect.
  • Electrophysiological data revealed larger N2 and P3 amplitudes when switching between German and Japanese post-training.
  • This suggests language control impacts domain-general executive control even in novice learners.

Conclusions:

  • Language control in newly learned languages influences domain-general executive control during the initial learning phase.
  • Findings support the adaptive relationship between bilingual language control and executive functions.
  • This highlights the cognitive flexibility associated with early stages of language acquisition.
