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...

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.

Introduction to Language of Pathophysiology l

Introduction to Language of Pathophysiology l

Pathophysiology investigates how biological mechanisms—typically starting at the cellular level—disrupt normal bodily functions. It bridges anatomy and physiology to explain the progression of disease. With this foundation, it is important to understand the following key terms used to describe disease processes: Diagnosis:The process of identifying a disease using clinical evaluation, including signs (objective evidence like rashes), symptoms (subjective experiences like pain), laboratory test...

This lesson explores key terms that describe how diseases progress, their outcomes, and their distribution in populations.Diagnostic tests identify diseases and monitor treatment. These include blood and urine tests, biopsies, imaging (X-ray, MRI), and detection of infectious agents.Remission is a reduction or disappearance of symptoms.Exacerbation refers to the worsening of symptoms, such as increased wheezing during an asthma attack.A precipitating factor triggers an acute episode, while a...

Summary

Narrative retelling and expressive syntax skills in children with Specific Language Impairment (SLI) predict long-term outcomes. Early articulation skills did not significantly predict prognosis in this longitudinal study.

Developmental Psychology

Background:

Specific Language Impairment (SLI) affects language development in children.
Longitudinal studies are crucial for understanding developmental trajectories and prognosis.
Identifying early predictors of language outcomes is essential for timely intervention.

Purpose of the Study:

To identify predictors of long-term outcomes in children diagnosed with Specific Language Impairment (SLI).
To examine the predictive power of early language and nonverbal skills on later prognosis.
To investigate the role of demographic factors in language development outcomes.

Main Methods:

Longitudinal study of 117 children diagnosed with SLI at age 7, reassessed at age 11.
Logistic regression analyses were used to identify significant predictors of overall prognosis.
Inclusion of language measures (narrative retelling, expressive syntax) and a nonverbal measure in predictive models.

Main Results:

Narrative retelling skills and expressive syntax were the strongest predictors of overall prognosis.
This predictive relationship remained significant even when a nonverbal measure was included.
Early measures of articulation did not independently predict later overall prognosis.
Demographic factors like maternal education and family income did not differ between outcome groups.

Conclusions:

Early narrative and expressive syntax abilities are key indicators for predicting the long-term language prognosis in children with SLI.
Articulation skills appear less critical for predicting long-term outcomes compared to narrative and syntactic abilities.
Findings underscore the importance of assessing higher-order language skills for prognostic evaluations in SLI.
