Summary
Children with perinatal stroke (PS) show altered language development into adolescence. Left hemisphere strokes impact morphology and syntax, while right hemisphere strokes affect complex syntax, indicating evolving neuroplasticity.
Area of Science:
- Neuroscience
- Developmental Psychology
- Linguistics
Background:
- Unilateral perinatal stroke (PS) in young children demonstrates brain plasticity for language acquisition.
- Language development continues into adolescence in typically developing children, but its trajectory in PS survivors is less understood.
Purpose of the Study:
- To investigate later language and discourse abilities in children (ages 7-16) with perinatal stroke.
- To determine if neuroplasticity for language persists into later childhood and adolescence in this population.
Main Methods:
- Analysis of spoken personal narratives from children with perinatal stroke (ages 7-16) and controls.
- Comparison of morphological errors, syntactic complexity, and discourse features between groups.
Main Results:
- Children with left hemisphere lesions exhibited more morphological errors, less complex syntax, and fewer syntactic types than controls.
- Right hemisphere lesion group performed comparably to controls, except for reduced use of complex syntax.
- Both PS groups showed impoverished story settings compared to controls.
Conclusions:
- Language development in children with perinatal stroke continues to evolve into adolescence, but with distinct patterns based on lesion location.
- Findings reveal the nature and extent of neuroplasticity for language, highlighting potential regional biases in the developing brain.

01:22Language 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...

01:27Language 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.
01:10Higher 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...

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.

01:29Three Developmental Domains
Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...
