Language Development

980
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

852
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.

Learning Disabilities01:25

Learning Disabilities

652
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Higher Mental Functions of the Brain: Language

3.9K
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

954
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...

Seizures: Classification01:13

Seizures: Classification

1.8K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Summary

Non-neurogenic language disorders (NNLDs) stem from psychological reasons, not brain damage. Recognizing these distinct communication impairments is crucial for identifying underlying psychological conditions.

Area of Science:

  • Linguistics
  • Psychiatry
  • Neurology

Background:

  • Non-neurogenic language disorders (NNLDs) are distinct from psychogenic speech disorders.
  • NNLDs arise from psychosomatic issues, conversion disorder, or psychiatric conditions.

Purpose of the Study:

  • To identify and classify the spectrum of NNLDs.
  • To characterize the features of NNLDs.

Main Methods:

  • Literature review on language disturbances with psychogenic or psychiatric origins.
  • Summarizing existing classifications and characteristics of NNLDs.

Main Results:

  • Proposed classification includes psychogenic aphasia, various psychogenic "lalias" (e.g., oxylalia, echolalia), psychologically-mediated word usage, psychotic language, and psychogenic foreign accent syndrome.
  • Identified specific types of NNLDs based on literature.

Conclusions:

  • NNLDs are underemphasized by clinicians and researchers.
  • Recognition requires distinguishing them from neurogenic impairments and identifying specific clinical features.
  • NNLDs can be primary indicators of psychological illness.
