Module 2 Describing language

1925: Speech Pathology established as a profession.
1926: American Academy of Speech Correction founded as a professional organization.
1950s: Focus shifted to treating speech issues among soldiers returning from war with brain injuries affecting speech.
1970s: Differentiation between language disorders and speech disorders began.

Formative Years (1900-1945)
- Establishment of professional practice and frameworks.
- Influenced by World War II.
Scientific/Academic Orientation (1945-1965)
- Focus on merging assessment and therapy approaches with psychology and communication.
Linguistic Era (1965-1975)
- Separation of speech therapy from language development.
Pragmatic Revolution (1975-Present)
- Emphasis on an inclusive approach including communication, linguistics, and culture in practice.

Understanding language development aids in discerning the mental processes underlying cognition and thought.
Objectives of Speech Language Pathologists (SLPs):
- Gain insights into normal and atypical language development processes.
- Investigate disordered communication focusing on causes, evaluations, and remediation strategies.
Theoretical Approaches:
- Varied methodologies such as behavioral and sociolinguistic frameworks enhance the study of language development.

NATURE: Genetic predispositions contribute to language abilities.
NURTURE: Language abilities are developed through environmental interaction.

Proponent: Noam Chomsky.
Core Ideas:
- Children are born with an innate ability for language acquisition.
- Brain is hardwired to process language from birth.
- Language is seen as a biological trait with universal grammar rules.
- Major notions include:
  - Disruption in biological function affects language acquisition ability.
  - Humans have a drive to communicate with an inbuilt capacity for language.
- Linguistic Universals: Core principles that persist across languages.
Language Acquisition Device (LAD):
- An innate mechanism posited by Chomsky enabling understanding and acquisition of any language at deep structure.

Human Brain Functionality:
- Wernicke’s Area: Associated with the comprehension of speech.
- Broca’s Area: Responsible for language production and processing.
- Primary Motor Strip: Controls voluntary movements, including speech production.
- Neural Plasticity: Suggests that brain changes as learning occurs; capabilities for language are genetically passed down.

Suggests that linguistic knowledge is acquired from interaction with the environment.
Key Assumptions:
- Language structures are learned from external linguistic input.
- Children are active participants in their learning, engaging in a give-and-take with caregivers.
- Structures emerge from practical usage of language in social contexts.
Child-Directed Speech (Motherese):
- Characteristics of this style include:
  - Use of short, simple sentences.
  - Focus on objects of child's interest.
  - Repeated praises and utterances.
  - Higher pitch and exaggerated intonation.
  - Significant pauses and frequent questions.

Aspect	Nativist	Constructionist
Major Focus	Language structure.	Language use.
Cognitive Contribution	Specific neural structures for language.	Structural emergence through social interactions.
Language Learning	Language rules learned innately.	Language evolved socially; rules learned through usage.
Origins of Language	Universal language rules exist.	Language adjusts to social needs.
Role of Environment	Limited; primarily biological.	Dynamic relationship influences language learning through interaction.

Theoretical Framework:
- An organized set of statements that describe, explain, or predict language behaviors.
- Assist in understanding the Nature vs. Nurture debate.
Strengths and Limitations:
- Provide structure for observations and guide assessment and intervention planning.

Key Principles:
- Language acquisition is a learned behavior influenced by the child's environment.
- Models include stimulus-response-reinforcement principles.
- Interaction between parent and child significantly impacts language development.
- Disruption in interactions alters language learning.

Cognitive Theory (Piaget):
- Language acquisition correlates with cognitive development stages.
- Language is part of broader cognitive abilities including thinking and problem-solving.
- Breakdown in cognitive function affects language learning.

Stage	Typical Age Range	Description	Developmental Phenomena
Sensorimotor	Birth to nearly 2 years	Engaging with the world through senses.	Object permanence, stranger anxiety, pretend play, egocentrism.
Preoperational	2 to about 6-7 years	Using intuitive rather than logical reasoning.	Conservation, mathematical transformations.
Concrete Operational	About 7 to 11 years	Logical thinking about concrete events.	Abstract logic, potential for mature moral reasoning.
Formal Operational	About 12 years through adulthood	Abstract reasoning development.

The mind processes information based on logical rules and strategies, applying multiple processes simultaneously rather than sequentially.

Stage	Description
Sensory Input	Initial information captured through the senses.
Sensory Memory	Very brief retention of sensory information.
Short-term Memory	Temporary storage for information; unrehearsed data lost.
Long-term Memory	Data eventually stored for long periods; retrieval may lose some info.

Practical methodologies include:
- Engaging students effectively; organizing information; using categorization techniques.
- Promoting repetitions and accommodations to improve processing.

Focuses on the functions served by communication.
Key Elements:
- Speech acts comprise locutionary, illocutionary, and perlocutionary actions.
- Language acquisition occurs within complex social environments with interactive partners.
- Parent-child interactions are pivotal; any disruption might impede language learning.

Emphasis on assessing communicative competence, evaluating diverse contexts and interactions.
Importance of dynamic assessment approaches to recognize the child's language proficiency.

The integration of theories provides a comprehensive understanding of speech language pathology from both biological and environmental perspectives.
Understanding of these frameworks aids in developing effective assessment and intervention strategies for language development issues.
