Language and Cognition

340
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

339
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...

Storage

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze...

Higher Mental Functions of Brain: Learning and Memory

729
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...

Interference and Decay01:16

Interference and Decay

127
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Higher Mental Functions of the Brain: Language

782
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...

Summary
This summary is machine-generated.

This study shows that both your first language (L1) and second language (L2) can influence third language (L3) learning. L1 aids implicit knowledge, while L2 boosts explicit knowledge of L3 grammar.

Area of Science:

  • Psycholinguistics
  • Neuroscience
  • Second Language Acquisition

Background:

  • Crosslinguistic influence (CLI) theories on third language (L3) acquisition are debated.
  • Previous research offers conflicting evidence regarding the source of CLI.

Purpose of the Study:

  • To investigate if both L1 and L2 can source CLI in L3 morphosyntactic acquisition.
  • To explore the neural correlates of L1 and L2 CLI in L3 processing using EEG.
  • To test predictions derived from the D/P model regarding L1/L2 memory systems.

Main Methods:

  • Exploratory electroencephalography (EEG) study.
  • Analysis of crosslinguistic influence on third language morphosyntactic acquisition.
  • Comparison of L1-sourced vs. L2-sourced facilitation.

Main Results:

  • Confirmed both L1 and L2 as sources of facilitation in L3 morphosyntactic acquisition.
  • L1 similarity consolidated L3 implicit knowledge and neurocognitive internalization.
  • L2 similarity enhanced L3 metalinguistic knowledge.

Conclusions:

  • L1 and L2 exert distinct influences on L3 learning.
  • This study provides preliminary neurocognitive insights into CLI mechanisms in L3 acquisition.
  • Findings support a nuanced view of crosslinguistic transfer in multilingualism.
