Language01:16

Language

900
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.
Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

Components of Language01:24

Components of Language

809
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.

Language Development01:22

Language Development

880
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 Cognition01:27

Language and Cognition

750
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.

Higher Mental Functions of the Brain: Language

3.5K
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...

Light Acquisition02:16

Light Acquisition

9.4K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Summary

Children set language parameters early, even without frequent input. Mandarin-speaking children demonstrated early mastery of null subjects and objects, indicating parameters are set independently of input frequency.

Area of Science:

  • Linguistics
  • Developmental Psychology
  • Computational Linguistics

Background:

  • Language acquisition theories propose parameter setting occurs either rapidly or gradually based on input frequency.
  • Previous models suggest input frequency significantly influences the speed of parameter acquisition.

Purpose of the Study:

  • To compare precipitous vs. gradual parameter setting models.
  • To investigate subject and object drop in Mandarin Chinese.
  • To analyze early language acquisition in Mandarin-speaking children.

Main Methods:

  • Corpus-based analysis of CHILDES database.
  • Studied speech data from 47 Mandarin-speaking children (1;2-6;5) and their caregivers.
  • Examined patterns of null subjects, null objects, and 'ba' constructions.

Main Results:

  • Children used null subjects and null objects correctly before 1;8.
  • Early setting of the null topic parameter was observed, irrespective of low evidence.
  • 'Ba' constructions reliably included objects from the start, despite scarce input.
  • Parameter setting occurred early and independently of input frequency.

Conclusions:

  • The study supports early parameter setting in language acquisition.
  • Findings suggest certain linguistic parameters are innate or rapidly acquired.
  • Input frequency is not the sole determinant of early parameter setting in Mandarin acquisition.
