Language Development01:22

Language Development

420
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...

Learning Disabilities

249
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.

Components of Language01:24

Components of Language

346
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.

Therapeutic Communication01:30

Therapeutic Communication

Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Language and Cognition01:27

Language and Cognition

403
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.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

180
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.

Summary

This project developed an augmentative and alternative communication (AAC) system for a Lakota-speaking child. It addresses the need for culturally relevant symbols and a synthesized Lakota voice for Indigenous language preservation.

Area of Science:

  • Linguistics
  • Speech-Language Pathology
  • Indigenous Language Revitalization

Background:

  • The COVID-19 pandemic necessitated a homeschool curriculum, including foreign language study.
  • A child learning the Native American Lakota language required an augmentative and alternative communication (AAC) system.
  • Existing AAC systems lacked culturally and linguistically appropriate resources for Lakota.

Purpose of the Study:

  • To describe the development of a grassroots augmentative and alternative communication (AAC) system for a Lakota-speaking child.
  • To address the need for culturally relevant symbols and a synthesized Lakota voice.
  • To create a model for developing AAC systems for other Indigenous languages.

Main Methods:

  • Programming over 1,600 Lakota vocabulary items into an electronic speech-generating AAC system (CoughDrop app on an iPad).
  • Identifying and developing culturally and linguistically appropriate symbols for the Lakota language.
  • Addressing the need for a synthesized voice that accurately captures Lakota prosody.

Main Results:

  • Successfully programmed over 1,600 Lakota vocabulary items into a child's AAC system.
  • Identified the need for and initiated the development of culturally appropriate symbols.
  • Recognized the necessity for and began addressing the creation of a synthesized Lakota voice.

Conclusions:

  • The project successfully initiated the development of a functional AAC system for a Lakota-speaking child.
  • The ongoing development aims to include culturally relevant symbols and an accurate synthesized Lakota voice.
  • The project's protocols may serve as a model for developing AAC systems for other Indigenous languages.
