Chapter 1 VENTO

Vocabulary flashcards covering core concepts of language acquisition, development, disorders, domains, and theoretical frameworks from Chapter 1.

Language

A complex and dynamic system of symbols used for thought and expression, which can be expressed orally, in writing, through symbols, or manually.

Speech

How sounds and words are said, involving articulation, rate of speech, sounds, and voice quality.

Communication

The exchange of information, ideas, needs, or desires between two or more individuals via symbolic or nonsymbolic information.

Developmental Language Disorder (DLD)

Diagnosed when an individual has difficulty understanding or using language in the absence of brain damage, hearing loss, or intellectual disability; it is the most frequently diagnosed language disorder.

Language Disorder

The impaired comprehension or use of spoken, written, and/or other symbol systems, which can represent a deficit in receptive or expressive language.

Receptive Language

A person's ability to understand and process language, which is typically better than expressive language.

Expressive Language

A person's ability to express and communicate meaning.

Late Language Emergence (LLE)

A delay in language onset in very young children under 3 with no other diagnosed disabilities or developmental delays in other cognitive or motor domains, also known as late talkers, late learners, or late bloomers.

Language Difference

A normal variation in communication being used that reflects regional, social, or cultural/ethnic factors, which does not equal a disability.

Language Acquisition

A pathway of acquiring language that happens naturally and unconsciously.

Language Development

A pathway of developing language that happens consciously.

Language Modalities

The four modalities through which language is processed and produced: reading, writing, listening, and speaking.

Descriptive-Developmental Approach

An approach that focuses on a student's language development and function (pragmatics, morphosyntax, semantics), prioritizing description of functioning over diagnostic labels to support developmental progress.

Brown's Morphemes

The 14 grammatical markers that emerge in a predictable order in early English language development, typically between 27 and 46 months.

Phonology

How speech sounds are organized and used.

Morphology

The study and use of word parts, such as tense, plurals, prefixes, and suffixes.

Syntax

Sentence structure and how words are arranged in sentences.

Content (Semantics)

The meaning of words and sentences.

Use (Pragmatics)

The social use of language, including dialect, prosody, irony, and sarcasm.

Evidence-Based Practice

The process of applying current, best external and internal scientific evidence, clinical expertise, and client perspective to make clinical decisions.

Clinical Expertise

One of the cornerstones of Evidence-Based Practice, referring to the knowledge, judgment, and critical reasoning acquired through training and professional experience.

Stakeholder Perspective

The unique set of personal/cultural circumstances, values, priorities, and expectations of the client and caregivers.

External Evidence

High-quality research evidence used as part of Evidence-Based Practice.

Internal Evidence

Evidence provided by the client's perspective/beliefs and the practitioner's clinical expertise.

Speech Chain Model

A basic framework used to explain how communication travels from the speaker's brain to the listener's brain, involving receptive and expressive language across three levels.

Level 1: Acoustic Level

The external physical energy level in the Speech Chain Model consisting of sound waves moving through the air from speaker to listener.

Level 2: Motor Level

The internal physical level in the Speech Chain Model involving the speaker's muscles for breath, voice, and speech sounds, and the listener's hearing mechanism.

Level 3: Linguistic Level

The meaning level in the Speech Chain Model focused on the brain's ability to turn physical signals into meaningful information.

Dialectal Difference

A specific type of language difference characteristic of a specific region or social group.
