Language Development

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...

Language and Cognition

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.

Learning Disabilities

Learning 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.

Higher Mental Functions of the Brain: Language

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...

Visual Agnosia

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Summary

This summary is machine-generated.

Children with language learning impairments (LLIs) struggle with speechreading but equally benefit from visual cues when listening in noise. This study highlights the importance of visual speech information for these children.

Area of Science:

Developmental Psychology
Speech and Hearing Science
Linguistics

Background:

Developmental language learning impairments (LLIs) can affect auditory processing.
Visual speech cues from a talking face can aid speech perception.
Understanding the use of visual speech in children with LLIs is crucial for intervention.

Purpose of the Study:

To assess the ability of children with LLIs to utilize visual speech cues.
To compare visual speech cue utilization in children with and without LLIs.
To investigate the impact of age on speechreading and visual cue use.

Main Methods:

Cross-sectional study comparing 41 typically developing children and 27 children with LLIs.
Participants completed silent speechreading and speech-in-noise tasks.
Visual support from a talking face was provided in some conditions.

Main Results:

Children with LLIs demonstrated a speechreading deficit compared to typically developing peers.
This deficit was more pronounced in older children with LLIs.
Both groups significantly benefited from visual cues in the speech-in-noise task, despite an overall developmental delay in speech perception for the LLI group.

Conclusions:

Children with LLIs are less accurate in speechreading and speech-in-noise tasks.
Both children with and without LLIs can effectively use visual speech cues to improve listening in noise.
Visual speech information is a valuable compensatory tool for children with LLIs.
