LANGUAGE DEVELOPMENT OVERVIEW

Infancy (0-12 months)

  • First 6 months: - Prelinguistic vocalizations without intentional communication.

  • Second 6 months: - Communication via crying, facial expressions, and body language (e.g., reaching out).

Toddlerhood (12-24 months)

  • 12-18 months: - 50-word vocabulary; one-word utterances.

  • 12-26 months: - One-word utterances with rising inflections (indicative of questions).

  • 18-24 months: - Two-word utterances.

TYPES OF LANGUAGE DISORDERS IN CHILDHOOD

  • Expressive Language: - Difficulties with expressing language (spoken/written).

  • Receptive Language: - Difficulties with understanding language (spoken/written).

  • Mixed Language Disorders: - Combinations of both expressive and receptive difficulties.

CLASSIFICATION OF LANGUAGE DISORDERS

I. ETIOLOGY

  • Types of Disorders: - Primary Disorder: - Occurs independently without involvement from significant other disabilities.

    • Secondary Disorder: - Arises due to another underlying condition (e.g., Autism, TBI, Down syndrome).

    • Developmental Disorder: - Present from birth; can be classified as primary or secondary.

    • Acquired Disorder: - Develops after birth due to external factors like trauma.

II. MANIFESTATION

  • Dyslexia: - Notably impacts reading skills; characterized by poor decoding despite good comprehension.

COMMON TYPES OF LANGUAGE DISORDERS

  • Specific Language Impairment (SLI):

    • A primary developmental language disorder defined by significant and unexplained expressive/receptive skills.

    • Presents without identifiable neurological problems.

  • Autism Spectrum Disorder (ASD):

    • Encompasses a range of developmental disorders characterized by communication struggles, social interaction issues, and restricted behaviors.

    • Emerges early in childhood, significantly affecting daily functioning.

    • Not merely explained by general intellectual disabilities.

    • Known risk factors include prenatal complications, other developmental disabilities, and sensory deprivation.

  • Intellectual Disability (ID):

    • Previously termed mental retardation; now intellectual developmental disorder (IDD).

    • Definition: Arrested or incomplete cognitive development, significantly below age expectations across conceptual, social, and practical skills.

  • Acquired Brain Injury (ABI):

    • Brain damage accrued post-birth due to traumas like accidents, poisoning, or infection.

    • Involves both open and closed head injuries, often impairing language and cognitive functions.

    • Common cognitive effects include fragmented discourse and word-finding difficulties.

ASSESSMENT PROCESS

COMPREHENSIVE LANGUAGE EVALUATION

  • Purpose: - To determine strengths and needs in language abilities, providing groundwork for improvement strategies.

  • Assessment Areas: - All language facets (content, form, use) should be evaluated, alongside the impact on overall functioning.

  • Administration: - Utilizing various approaches: norm-referenced, criterion-referenced, dynamic assessments, and observations to ensure comprehensive insight.

DIAGNOSIS

  • Misdiagnosis Risks: - False Positive: Inaccurately labeling a child as having a disorder due to factors like poor test construction or cultural differences.

    • False Negative: Under-identifying a disorder potentially leading to a lack of necessary interventions.

TREATMENT OF LANGUAGE DISORDERS

EVIDENCE-BASED PRACTICE

  • Focused on tailored treatments based on individual needs.

TREATMENT TARGETS

  • Objectives address specific areas: form, content, use, while utilizing age-appropriate norms.

TREATMENT STRATEGIES

  • Approaches include: - Child-Centered: Child-directed pace; facilitation of language through interests.

    • Clinician-Directed: Structured instruction by clinicians to elicit specific responses regularly.

TREATMENT CONTEXTS

  • Setting applications, ideally using various environments (home, school) for generalization of skills learned during therapy.

BENEFITS OF NATURAL ENVIRONMENT

  • Engaging in natural settings leads to better skill transfer and more functional use of language.

  • Encourages involvement of family and integration of treatment into daily settings for substantial outcomes.

READING AND WRITING GOALS

  • Collaboration among educators (SLPs, teachers) to address foundational reading skills is crucial for effective learning.

  • Key foundational skills include: - Phonological Awareness

    • Alphabet Knowledge

    • Print Concept Knowledge

    • Alphabetic Principle

    • Reading Fluency

PHONOLOGICAL AWARENESS

  • Ability to manipulate units of oral language significantly affects reading success.

  • Includes: - Word awareness (breaking speech into words)

    • Syllable awareness (recognizing syllable structures)

    • Phonemic awareness (segmenting and blending sounds).

ALPHABET KNOWLEDGE

  • Understanding uppercase and lowercase letters alongside letter-sound connections is integral to reading success.

PRINT CONCEPTS KNOWLEDGE

  • Awareness of how print functions and is structured within texts; includes understanding print organization and usages in different contexts.

ALPHABETIC PRINCIPLE

  • Recognizing the conventional relationship between sound and printed language enhances reading efficiency; includes ability to blend and identify sequences within words.

READING FLUENCY

  • Reading fluency involves appropriate reading speed and expression with minimal errors; practice and matching reading levels for materials are vital for effective development.
