Speech, Language, and Cognitive Development Review

Vocabulary flashcards covering core concepts, theories, developmental milestones, anatomical structures, and design features across all five lecture modules on speech and language development.

Communication

The process of sending and receiving information, ideas, feelings, or messages.

Language

A system of abstract symbols and rule-governed structures encompassing receptive language, expressive language, pragmatics, semantics, syntax, and morphology.

Speech

The oral expression of language, requiring the complex physiological coordination of respiration, phonation, resonation, and articulation.

Receptive Language

The ability to listen, process, and understand the language produced by others or to think through an idea.

Expressive Language

The production of language from one's own thoughts through speaking, signing, or writing.

Pragmatics

The component of language governing the rules for language use within social contexts.

Semantics

The component of language concerned with the meaning of words and sentences.

Syntax

The rule-governed system that dictates the structural arrangement and combination of words within sentences.

Morphology

The study of the structure and form of words in language, dealing with morphemes as the basic building blocks of words.

Suprasegmentals

Prosodic features of speech that overlay segments, including stress, intonation, pitch, loudness, rate/tempo, and rhythm.

Stress

The emphasis placed on specific syllables or words in speech, which can distinguish word meaning (e.g., 'record vs. re'cord) and highlight key information.

Intonation

The rise and fall of vocal pitch across speech, used to distinguish sentence types (statement vs. question) and convey emotion.

Speech Chain

A 6-step process connecting a speaker's thoughts to a listener's understanding: Conceptualization -> Linguistic Encoding -> Physiological Production -> Acoustic Signal -> Auditory Reception -> Comprehension.

Displacement

A design feature of human language allowing individuals to communicate about things, events, or ideas not present in the immediate time or space.

Productivity (Openness)

A design feature of language enabling speakers to produce and comprehend an infinite number of novel messages.

Duality of Patterning

A design feature where meaningless discrete units (sounds) are combined into meaningful units (words), which are further combined into larger structures (sentences).

Reflexiveness (Metalinguistic Ability)

The capacity to use language to reflect upon and describe language itself.

Recursion

The ability to embed grammatical structures within other structures of the same type in a sentence.

Prevarication

The ability to use language to lie, deceive, or generate intentionally meaningless statements.

Nativist Perspective

The theoretical view led by Noam Chomsky asserting that language acquisition is an innate, biologically programmed capability universal to humans.

Language Acquisition Device (LAD)

An innate mental structure postulated by nativists that houses universal linguistic rules and allows children to acquire language rapidly.

Transformational Generative Grammar

Noam Chomsky's theory that language operates on two structural levels—deep structure (underlying meaning) and surface structure (spoken form)—governed by phrase structure rules and transformations.

Behaviorist Perspective

The theoretical view championed by B.F. Skinner stating that language is learned behavior shaped by environmental consequences, operant conditioning, reinforcement, and imitation.

Skinner's Verbal Behavior Functions

Functional categories of verbal behavior defined by B.F. Skinner: Echoic (imitation), Tact (labeling), Mand (requesting), Intraverbal (responding), and Autoclitic (commenting/modifying).

Case Grammar

Charles Fillmore's semantic theory proposing that sentences consist of modality (verb, tense, negation) and propositions containing universal noun-verb relationships (agentive, dative, experiencer, factitive, instrumental, locative, objective).

Parallel Distributed Processing (PDP)

An information processing model holding that cognitive processing and language acquisition occur simultaneously across interconnected neural networks.

Language Acquisition Support Structure (LASS)

Jerome Bruner's concept that caregiver interactions and environmental formatting provide structured scaffolding necessary for language learning.

Speech Act Theory

A framework developed by Austin and Searle dividing utterances into three acts: Locutionary act (actual utterance), Illocutionary act (speaker's intent), and Perlocutionary act (effect on listener).

Piaget's Constructivist Perspective

The perspective that children actively construct knowledge through environmental exploration across four fixed stages: Sensorimotor (birth to 2 years), Preoperational (2-7 years), Concrete operational (7-11 years), and Formal operational (12 years and older).

Adaptation of Schemas

The cognitive cycle where individuals assimilate new information into existing schemas, experience disequilibrium when mismatches occur, accommodate by modifying schemas, and restore equilibrium.

Zone of Proximal Development (ZPD)

Vygotsky's learning concept defined as the gap between what a learner can achieve independently and what they can achieve with guidance from a More Knowledgeable Other (MKO).

Scaffolding

Temporary, structured support provided by a More Knowledgeable Other (MKO) during a learning task within the Zone of Proximal Development.

Private Speech

Self-directed spoken language used by individuals out loud to regulate behavior and solve problems.

Multiple Intelligences Theory

Howard Gardner's model proposing eight distinct intelligence modalities: Linguistic, Logical-Mathematical, Spatial, Musical, Bodily-Kinesthetic, Interpersonal, Intrapersonal, and Naturalistic.

Dynamic Systems Theory

A framework stating that cognitive abilities and language emerge dynamically from moment-to-moment interactions among biology, environment, experience, and culture.

Shape Bias

A dynamic task-driven learning phenomenon where children generalize a newly learned word to other objects sharing a similar shape rather than color or size.

McGurk Effect

A perceptual phenomenon illustrating multisensory integration, where conflicting visual and auditory speech cues alter what speech sound is perceived.

Executive Functions

Core cognitive management processes including Impulse Control (Inhibition), Emotional Control, Flexible Thinking (Cognitive Flexibility), Working Memory, Self-Monitoring, Task Initiation, Planning and Prioritizing, and Organization.

Contingent Responding

A communication dynamic where a caregiver promptly adapts interactions to an infant's cues, and the infant responds with motor activity, cooing, or smiling.

Joint Reference

A shared focus between communication partners on the same object or event, established through gestures, vocalizations, and words across four developmental phases.

Fast Mapping

The process where children rapidly acquire word meanings upon initial exposure without explicit teaching, driven by auditory cues, phonological representations, and semantic activation.

Prelinguistic Vocalizations

The developmental sequence of infant vocal output prior to true words: Reflexive cries and vegetative sounds (0-1 mo), Cooing and differentiated crying (1-4 mo), Marginal and reduplicated babbling (5-8 mo), and Echolalia, variegated babbling, jargon, and protowords (8-12 mo).

Perlocutionary, Illocutionary, and Locutionary Stages

Developmental stages of speech acts in infants: Perlocutionary (0-8 months, reflexive responses), Illocutionary (8-12 months, intentional gestures/vocalizations), and Locutionary (12+ months, first meaningful words).

Mean Length of Utterance (MLU)

A metric calculating the average number of morphemes per utterance in a child's speech sample, calculated as $\text{MLU} = \frac{\text{Total Morphemes}}{\text{Total Utterances}}$.

Brown's Stage 1

The initial syntactic stage divided into Early Stage 1 (ages 12-22 months, MLU $1.0 - 1.5$, single-word utterances) and Late Stage 1 (ages 22-26 months, MLU $1.5 - 2.0$, beginning of two-word combinations and syntax).

Respiration

The speech process of breathing that provides required airflow; during speech, exhalation is extended up to 15 seconds compared to 2.5 seconds in quiet breathing according to Boyle's law.

Phonation

The production of speech sound occurring in the larynx as exhaled air forces closed vocal folds to vibrate through subglottal pressure buildup and aerodynamic forces.

Vocal Fold Vibration Cycle

The sequential 5-step phonatory cycle: 1. Folds close to restrict airflow. 2. Pressure builds beneath folds. 3. Pressure blows folds apart. 4. Pressure drops below folds. 5. Elasticity snaps folds together.

Resonation

The modification, shaping, and amplification of vocal fold tone as sound passes through the pharyngeal, oral, and nasal resonating cavities.

Articulation

The precise movement of oral structures (teeth, tongue, lips, jaw, and palate) to break the airstream into distinct speech sounds.

Cortical Language Pathway

The neural pathway where auditory comprehension occurs in Wernicke's area, signals pass along the arcuate fasciculus to Broca's area for speech production and grammar organization, and travel to the motor cortex to execute speech movements.

Pyramidal System

The central nervous system pathway that controls fine motor movements of speech, delivering precise muscle commands to articulators like the tongue and lips.

Ear Anatomical Structures

The auditory apparatus divided into outer ear (pinna, ear canal), middle ear (tympanic membrane, ossicles: malleus/hammer, incus/anvil, stapes/stirrup), and inner ear (oval window, cochlea, perilymph/endolymph, hair cells/cilia, Organ of Corti, auditory nerve).
