Higher Mental Functions of the Brain: Language01:10

Higher Mental Functions of the Brain: Language

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...
Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Language and Cognition01:27

Language and Cognition

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.
Modeling in Therapy01:26

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in situations...
Language Development01:22

Language Development

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...

Summary
This summary is machine-generated.

People who stutter (PWS) exhibit speech motor skill limitations, struggling with practice-based improvements and long-term retention. They show less efficiency and flexibility in adapting to speech motor demands.

Area of Science:

  • Speech-language pathology
  • Neuroscience
  • Motor control

Background:

  • Stuttering is a complex disorder affecting speech fluency.
  • Previous research suggests potential motor control deficits in stuttering.

Purpose of the Study:

  • To review evidence for speech motor skill limitations in people who stutter (PWS).
  • To examine differences in practice-based learning and adaptation between PWS and non-stuttering individuals.

Main Methods:

  • Review of behavioral, kinematic, and neuroimaging studies.
  • Analysis of data on practice improvement, long-term retention, and adaptation efficiency.

Main Results:

  • PWS demonstrate limitations in improving speech motor skills with practice.
  • PWS show reduced long-term retention of practiced speech motor changes.
  • PWS exhibit less efficient and flexible adaptation to motor and cognitive-linguistic demands impacting speech.

Conclusions:

  • PWS may possess inherently lower speech motor skills compared to non-stuttering individuals.
  • Findings support the Speech Motor Skills approach to understanding stuttering.
