Language Development

644
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...

Language and Cognition

566
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.

Components of Language01:24

Components of Language

581
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.

Typical Model Studies

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Variability: Analysis

288
Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

Higher Mental Functions of the Brain: Language

2.5K
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...

Area of Science:

  • Linguistics
  • Sociolinguistics
  • Phonetics

Background:

  • Finnmark North Sámi is an endangered indigenous language variety spoken in Norway and Finland.
  • Speakers are bilingual, regularly using Finnish or Norwegian alongside North Sámi.
  • Understanding language contact influences on endangered languages is crucial.

Purpose of the Study:

  • To investigate majority language influences on Finnmark North Sámi prosody.
  • To identify specific prosodic characteristics affected by bilingualism.
  • To associate these changes with intonational patterns of Finnish and Norwegian.

Main Methods:

  • Developed a novel methodology to automatically detect prosodic differences in speech.
  • Utilized convolutional WaveNet speech synthesis models trained on North Sámi data.
  • Employed conditioning embeddings to pinpoint words exhibiting the most significant prosodic variations.

Main Results:

  • Prosodic differences were not uniform across all word types (part-of-speech).
  • Identified specific intonational patterns showing variation between Finnmark North Sámi varieties.
  • Found evidence suggesting differences reflect phrase-level prosodic features of majority languages.

Conclusions:

  • Majority languages significantly influence the prosody of Finnmark North Sámi.
  • Prosodic variations are linked to phrase-level characteristics of Finnish and Norwegian.
  • This research offers insights into language contact phenomena in endangered minority languages.
