Summary
Children with developmental language disorder may have less flexible speech self-monitoring. Task demands impact disfluency patterns differently in these children compared to typically developing peers.
Area of Science:
- Linguistics
- Developmental Psychology
- Speech-Language Pathology
Background:
- Speech disfluencies are common in spontaneous speech for both children and adults.
- Understanding disfluency in children with developmental language disorder (DLD) is crucial for assessing self-monitoring abilities.
Purpose of the Study:
- To evaluate linguistic disfluencies in Russian-speaking children with DLD and typically developing (TD) peers.
- To analyze disfluencies through the lens of the dynamic adaptive model of self-monitoring in speech production.
Main Methods:
- Collected four language samples from 10 children with DLD and 14 TD children (storytelling, conversation, argument).
- Transcribed audio recordings and marked linguistic disfluencies.
- Conducted structured distributional analysis of disfluency indexes.
Main Results:
- Overall disfluency rates were similar between children with DLD and TD children.
- Task type significantly impacted the rate and profile of different disfluency subtypes.
- Task-related patterns in disfluency indexes differentiated the DLD and TD groups.
Conclusions:
- Children with DLD may exhibit reduced flexibility in their adaptive self-monitoring system.
- Task-specific changes in disfluency profiles might be limited in children with DLD.
- Linguistic disfluency analysis offers insights into speech production and self-monitoring in developmental disorders.

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...

01:25Learning Disabilities

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.

01:27Language and Cognition
401
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.

01:24Components of Language
345
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.

01:22Vygotsky's Cognitive Development in Cultural Context
140
Lev Vygotsky, a pioneering Russian psychologist, developed a theory of cognitive development that centers on the influence of social and cultural factors. Unlike Jean Piaget, who emphasized the child's direct interaction with the physical world as key to development, Vygotsky argued that cognitive growth is an interpersonal process that unfolds within a cultural context. For Vygotsky, a child's learning cannot be separated from their social environment, which includes the values,...

01:10Higher Mental Functions of the Brain: Language
955
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...
