Objectives

• Understand language acquisition theories (generative/nativist and constructionist).
• Define child-directed speech (CDS) and emergentism.
• Analyze the effect of data collection methods on results.
• Assess the impact of sample size and variability on resultant data.
• Discuss the issues of naturalness and representativeness in data.
• Describe the data collection and analysis procedures.

Introduction

• Language development involves the process through which individuals learn and acquire language skills throughout their lives.
• It encompasses the progression from early babbling in infancy to the sophisticated use of language in adulthood.
• Language development includes aspects such as listening, speaking, reading, and writing.

History

• Individuals have been fascinated by the exploration of language development for thousands of years.
• Psammetichus I, an ancient Egyptian pharaoh, conducted a child language study in the 7th century BCE.
• Two children raised with sheep and deprived of human speech didn't develop normal language.
• Figures like Saint Augustine and Charles Darwin have written about language development.

Why Study Language Development?

• Modern researchers have dedicated their careers to studying language development.
• Studying language development is crucial for understanding overall human development.
• Understanding language development is essential for early childhood education.
• Studying child language helps special educators and speech-language pathologists to better understand normal and abnormal language development in children.
• Interest in language development stems from the complex and fascinating nature of language itself.
• Studying language development helps understand human behavior and mental processes.
• Professionals frequently disagree on the best way to study language development.

Who Studies Language Development?

• Linguists describe language symbols and rules for forming language structures.
• Psycholinguists study the psychological processes behind language (mental mechanisms).
• Sociolinguists examine language use based on social factors (roles, levels, and contexts).
• Behavioral psychologists focus on the behavioral context of language.
• Speech-language pathologists study disordered communication, causes, extent, and remediation.

Linguistic Theory: Nature vs. Nurture

• The nature vs nurture debate focuses on whether language is innate or learned.
• Nature emphasizes inborn biological factors, genetic and neurological predispositions, and innate linguistic abilities that unfold naturally.
• Nurture highlights the impact of environmental factors, such as experience shaping language, interactions, and cultural surroundings.

Generative Approach

• Nativist approach assumes children are born with innate rules related to language structures (Chomsky).
• Generativists believe that children learn language by utilizing an innate Language Acquisition Device (LAD).
• The LAD, housed in the brain, contains innate syntactic rules from birth.
• Early Generative theories were criticized for being adult-centered and lacking evidence regarding the need for adult-like categories or rules for children.

Generative Approach (cont.)

• The semantic revolution of the 1970s proposed a semantic-cognitive basis instead of syntax for children's early language.
• Semantic relations in children's language align with their sensorimotor development.
• Children used meaning units (agents, actions, objects) instead of grammatical subjects and verbs.
• Nonlinguistic units (Mommy eat cookie, Daddy throw ball) might be the basis for linguistic structures (agent-action-object).
• Formal grammar poses challenges.

Generative Approach (cont.)

• Challenges existed with the use of formal grammar for explaining language acquisition, since no single formal grammar explained all cultures.
• Some argued that semantic-cognitive processes, not syntax, are fundamental in children's early language development.
• Later adult syntactic models proposed returning to a continuity assumption where children have the same basic linguistic categories and rules as adults.

Generative Approach (cont.)

• Linguistic nativism suggests that all humans have the same basic linguistic competence throughout their lives, with universal grammar proposed by Chomsky.
• Generative grammar views natural languages as formal languages with abstract algebraic rules that are meaningless but combine to form meaningful units.

Generative Approach (cont.)

• Universal grammar is innate, used by all children to abstract language.
• Language Acquisition contains two components; learning words and connecting language to universal grammar.
• Language learning is continuous.
• Issues with fixed/semi-fixed structures like "How's it going?"

Generative Approach (cont.)

• Problems with applying theories to second language learners arose due to non-literal meanings of phrases not being part of core grammar rules (memorized as single units).

Interactionalist Approach

• Recognizes interactive nature of nature and nurture in language development.
• Acknowledges that a combination of biological predisposition and environmental factors combine to foster language acquisition.
• Children learn through input from their environment.

Interactionalist Approach (cont.)

• Child's role is active participation in learning language.
• The learner and the environment interact dynamically.
• Child-directed speech (CDS) is adapted from parental speech to aid language acquisition.

Interactionalist Approach (cont.)

• Background emphasizes learning language as a behavior.
• Two aspects of interactionalist approach: Constructionism and Emergentism.
• Constructionism believes language structures are actively built alongside meaning using morphemes, words, sentence frames, and interactions.
• Emergentism states that language structures develop from the brain's existing patterns and environmental interactions.

Interactionalist Approach (cont.)

• The usage-based approach shows that children's consistency in using grammatical structures is still evolving toward adult-like representations.
• The child uses phrases in certain contexts and builds on those contexts to acquire better grammar over time.

Interactionalist Approach (cont.)

• Children develop abstract categories and schemes through intention-reading (meaning behind) and pattern-finding (more abstract dimensions).
• The interactionalist approach (not relying on universal grammar) isn't required to explain language use in a child.
• Language development in children isn't solely based on one source; it includes elements of environment and inherent understanding of patterns .

Interactionalist Approach (cont.)

• Criticism of interactionalism suggests that it doesn't sufficiently explain the similarities of language development among children and might be less helpful in explaining children with language impairment.
• Comparison highlights the difference and similarities between the universal and usage-based theories; how language learning differs from those whose language needs special support (impaired).

Language Research and Analysis

• Linguistic research involves gathering, evaluating, and reporting data from studies about child language development.
• Research involves discovering general linguistic principles, understanding links between language and cognition, and creating a theoretical model of child language development.

Conclusion

• The presentation concluded by explaining the differences between nature and nurture.
• The course discussed child language development based on information gathered from studies about child language.
• Data collection procedures are important for valid, reliable, and objective reporting.
