Components of Language

316
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.

Stability of Substituted Cyclohexanes02:30

Stability of Substituted Cyclohexanes

12.7K
This lesson discusses the stability of substituted cyclohexanes with a focus on energies of various conformers and the effect of 1,3-diaxial interactions.
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...

Disubstituted Cyclohexanes: cis-trans Isomerism

12.0K
Depending upon the different spatial orientation of the substituents, the disubstituted cycloalkanes exhibit two types of stereoisomers. The cis isomers have the substituents on the same side of the ring, whereas the trans isomers have the substituents on the opposite sides. These stereoisomers exhibit different physical properties and cannot be interconverted without breaking the carbon-carbon bonds.
In cyclohexane, the substituents can occupy different positions generating distinct isomers....

Language and Cognition

374
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.

Area of Science:

  • Linguistics
  • Computational Linguistics
  • Psycholinguistics

Background:

  • Existing Welsh word frequency databases, such as the Cronfa Electroneg o'r Gymraeg (CEG), may provide inconsistent frequency estimates.
  • Accurate word frequency data is crucial for various linguistic and cognitive research.

Purpose of the Study:

  • To introduce SUBTLEX-CY, a novel word frequency database for the Welsh language.
  • To evaluate the reliability of SUBTLEX-CY frequency estimates against existing Welsh corpora.

Main Methods:

  • A 32-million-word corpus of Welsh television subtitles was used to create SUBTLEX-CY.
  • A lexical decision task compared SUBTLEX-CY frequency estimates with those from CEG and other databases.
  • Reaction times were analyzed for words classified as high frequency (HF) in CEG versus medium frequency (MF) in both databases.

Main Results:

  • Words classified as HF in CEG but MF in SUBTLEX-CY showed slower reaction times, indicating less reliable frequency estimation in CEG.
  • SUBTLEX-CY demonstrated more consistent and reliable word frequency estimations.

Conclusions:

  • SUBTLEX-CY provides a more accurate and reliable resource for Welsh word frequencies.
  • The database includes valuable lexical information such as part-of-speech and contextual diversity.
  • SUBTLEX-CY is freely available for research on the Open Science Framework.
