    Study Notes

    Language Development - Introduction

    • Language is a complex and dynamic system of conventional symbols used for thought and communication (ASHA, 1982).
    • Language is a system of symbols.
    • The system of language is conventional.
    • The language system is dynamic.
    • Language is a tool for human communication.

    Language as a System of Symbols

    • Language can be considered a code that translates information using symbols.
    • In human language, specific words represent specific concepts, items, thoughts, and so on.
    • Examples include using "happy" to describe feelings, "rose" for a flower, and "far" for distance.
    • The relationship between a word and its referent (the aspect of the world the word refers to) is arbitrary. For example, "happy" refers to a specific feeling but other words could also be used.

    The System of Language is Conventional

    • Language systems use accepted and fixed rules.
    • Adhering to conventions allows all members of a language community to use language as a means of expression.
    • A group of people who share a common language are known as a language community.
    • Language communities emerge due to geographical, social, and economic reasons.

    The Language System is Dynamic

    • Language is constantly changing, both within individuals learning it and within communities using it..
    • Language acquisition begins at birth or even before.
    • Language skills develop throughout life.
    • A community's language evolves as new vocabulary emerges.

    Language is a Tool for Communication

    • Communication is the process of sharing information, thoughts, feelings, and ideas amongst two or more people.
    • Language is a central part of this process.

    Language as a Module of Human Cognition

    • Language is a cognitive tool for developing the perception of the world.
    • Language is a representational tool that allows people to communicate their thoughts to others.
    • Initially, language evolved culturally and socially rather than biologically.

    Language as an Inner Representational Tool

    • The brain uses language as a tool for storing information and managing cognitive processes like reasoning, hypothesizing, memory, planning, and problem-solving.
    • This is important for mathematical and scientific reasoning.

    Using Language for Thinking

    • Example scenarios use language to describe thinking processes.

    How Does Language Relate to Speech, Hearing, and Communication?

    • Speech is the neuromuscular process of converting language into sound signals.
    • Hearing is the sensory system that allows speech to be processed by the brain.
    • Communication involves sharing information between individuals combining language, speech, and hearing.

    Models of Speech Production

    • Speech production comprises of three stages: perceptual target (representing sound), motor schema (motor plan), and speech output (physical articulation).
    • These stages involve phonemes, syllables, and words.

    Relationship to Speech and Language

    • Locked-in syndrome demonstrates that language function can exist separate from normal speech.

    Hearing

    • Hearing includes general auditory perception and speech perception.
    • Speech perception refers to the brain's processing of speech and language.
    • Auditory perception describes the processing of various auditory inputs besides speech.
    • Statistical learning plays a role in language development.

    Communication

    • Communication involves four basic processes: formulation, transmission, reception, and comprehension.
    • Communication intentions are a classification of the purpose of communication.

    Types of Communication

    • Symbolic communication (using symbols to convey messages).
    • Preintentional communication (communication without specific intent).
    • Intentional communication (communication purposeful messages).

    Purpose of Communication

    • Various purposes for communication (e.g. Instrumental, Regulatory, Interactional, Personal, Heuristic, Imaginative, Informative).

    Main Domains of Language (LAHEY, 1988)

    • Form (sentence structure, word prefixes, suffixes, sound organization).
    • Content (the meaning behind words, vocabulary systems).
    • Use (the intent behind communication, various communication intentions, e.g., Halliday's seven communication intentions).

    Components of Language (Form, Content, Use)

    • Phonology (sounds of language), Morphology (internal structure of words), Syntax (rules governing sentence structure), Semantics (word meanings), Pragmatics (social meaning of language).

    Phonology

    • Phonology governs the sounds in syllables and words.
    • Allophones are subtle variations of phonemes due to context.
    • Phonotactics are rules governing sound organization within words.

    Morphology

    • Morphology deals with internal word structures.
    • A morpheme is the smallest unit of meaning in a word.
    • Morphemes can be prefixes, suffixes, or roots affecting word meanings.

    Syntax

    • Syntax governs sentence structure.
    • Syntax enables creating questions, embeddings, and complex sentences.

    Semantics

    • Semantics concerns word and phrase meanings.

    Pragmatics

    • Pragmatics examines language's social use.
    • Pragmatics involves using language for different functions, organizing language in discourse and knowing social conventions.

    Remarkable Features of Language

    • Acquisition rate (speed of learning).
    • Universality (similar cognitive structures across languages).
    • Species specificity (a uniquely human capacity).
    • Semanticity (ability to represent events).
    • Productivity (creating new sentences).

    Acquisition Rate

    • Early language acquisition is sensitive to environmental influences.
    • A critical period is the period of rapid early language acquisition.
    • The study of Romanian infants exemplifies the importance of early environments.

    Universality

    • Languages display variations in syntactic organization but share similar cognitive structures.
    • Children across the world demonstrate similar language acquisition with similar milestones at similar times.

    Species Specificity

    • Language in humans is a unique capability, unlike non-human communication.
    • Non-human communication lacks the same level of abstraction and flexibility as human language.

    Semanticity

    • Human language allows the representation of decontextualized events.
    • Human Language allows people to speak about the past and plan for the future.

    Productivity

    • Language's productivity lies in its ability to create infinite sequences of sentences.
    • A constrained number of words allows an unlimited number of novel sentences.

    Language Differences

    • Language differences exist among individuals and groups.
    • Differences relate to the language being learned, gender, temperament, and the learning environment.

    Dialect

    • Dialects are natural variations of language, reflecting cultural or geographical norms.
    • Variations in form, content, and use distinguish dialects from each other.

    Bilingualism

    • Bilingualism involves learning two or more languages.
    • Children raised bilingually may show differences in syntax/vocabulary exchanges.
    • Code-switching is a phenomenon where bilingual speakers switch between two languages in conversation.

    Bilingualism (Types)

    • Simultaneous bilingualism (learning two languages from birth).
    • Sequential bilingualism (learning a second language after mastering a first language).

    Gender

    • Girls tend to develop their vocabulary earlier than boys.
    • Boys are sometimes more likely than girls to present with language impairment.

    Genetic Prepositioning

    • Twin studies help understand the genetic contribution to language skills.
    • There is evidence to suggest that both inherited and environmental factors contribute to language learning and development.

    Language Learning Environment

    • Quantity refers to the total amount of language exposure.
    • Quality refers to the characteristics of the language environment, including caregiver word/sentence use, the intent/meaning of such language use.
    • Caregiver quality is positively correlated with accelerated language development.

    Language Disorders

    • Heritable language impairment is a language difficulty typically occurring without mental difficulties.
    • Specific Language Impairment (SLI) is a heritable language disorder that affects approximately 7 to 10% of children.

    Language Disorders (Continued)

    • Developmental Disability Language Impairment frequently accompanies other developmental difficulties.
    • This co-occurrence can result in multiple impairments.
