Language Development Theories Antecedents of language acquisition Vocabulary Grammar
Lack of Stimulation – Maltreated children • The Story of Genie • Abused and never spoken to since birth. • Discovered at age 13, given rehabilitation. • Was able to use speech much like that of a young child (“Another house have dog”). • Never able to reach the proficiency typical for her age.
deafness • Language does not depend on the auditory-vocal channel. • The American Sign Language (ASL) involves a system of gestures. • ASL has hand shapes & positions for each word composition. • Babies born to deaf ASL users (whether or not they are deaf) can learn from caregivers through informal interaction.
blindness • Blind children learn language just as rapidly and as well as sighted children. • Vision-related words like “look” and “see” are understood in a different way – use of hands rather than eyes. • Color words are learnt even without personally experiencing them – they can talk about the colors of things they are familiar with.
Language impairments • Aphasia • Disorder of language produced by lesions in certain areas of the cortex in the left hemisphere. • A lesion in Broca’s area = nonfluent aphasia (speech difficulty). • A lesion in Wernicke’s area = fluent aphasia (comprehension difficulty)
Language impairments • Specific Language Impairment (SLI) • Syndrome in which individuals are very slow to learn language. • Not caused by developmental disorders or brain damage. • Throughout life, difficulty in understanding and producing many sentences, even though intelligence seems normal.
Second language learning • Knowledge of the first or native language is so much better than knowledge of a second or third language. • Evidence shows that the brain loci of late-learned languages usually are different from those of the first learned language. • The older a person who is learning a second language, the more difficult it is to become fluent in that language.
The critical/sensitive period hypothesis • There is a sensitive developmental period for language learning. • Language is most easily acquired in early childhood. • Evidence for sensitive periods for language acquisition comes from studies of severely maltreated children and second language learning.
Babies’ Communicative Efforts LANGUAGE DEVELOPMENT
Infant-Directed Speech (also motherese) • Parents and infants engage in dialogue of sounds, gestures, facial expressions. • Infant grows as a communicative partner (Schaffer, 1996).
Gesturing sets the stage for languagedevelopment…. (Goldin-Meadows, 2007)
Using Gestures Protodeclarative • Gesture intended to make a statement about an object. Protoimperative • Gesture intended to get another person to do something for the child. • 6 months - most babies learn to use pointing gesture. • End of 1styr, gestures to communicate, share their intentions with another (Tomasello et al. 2007).
Beyond Gesturing….. Receptive Language Expressive/Productive Language
Receptive Language –Early Speech Perception • As early as 1 month of age, infants can perform categorical speech perception. • Ability to discriminate speech sounds, e.g. consonants. • Exposure to specific or native languages determines ability to distinguish and categorize specific sounds/phonemes.
Discriminating between languages • 4-day-old babies in France & America can discriminate between English and French speech. • By 2 months, babies listen longer when their own native language is spoken.
Tuning in to one’s own language…. • Infants lose the ability to make phoneme distinctions that are NOT used in their language community. • Japanese infants stop distinguishing between “la” and “ra”. • Babies begin to listen specifically for the particulars of their own language.
Productive Language – Early Speech Production • Production of sounds in 1styr follows orderly 4-stage sequence. • Crying Cooing Babbling Patterned Speech. • Cultural differences in prespeech sounds emerge around the babbling stage. • Babies start to tune in to the specific sounds of their native language.
How Children Acquire Words • Different views on how children associate a word with an object. • Associations combined with attention to perceptual similarity. • Use of social cues from adults to learn what a word labels. • Use of multiple cues that changes with age – perceptual at early stage, social later.
How Children Acquire Grammar • By 2yrs of age, children begin to use 2-word utterances (Telegraphic Speech/TS). • E.g. ‘there book’, ‘more milk’ • TS includes crucial words needed to convey the speaker’s intent. • From 2 yrs onwards, children learn the rules of grammar – understanding and acquiring morphemes (-s, -ing)
Grammatical Flowering (deVilliers & deVilliers, 1992). • In 3rd year of life….. • Sentence construction improves. • Increasing types of verbs, and tenses. • Ability to pose questions, using wh- words (what, which, where, why). • Expressions of negation (e.g. “That not daddy”, “No go school”).
Language Development The Social Use of Language Bilingualism
Using language socially Children use language as a social tool through…. • Speech Acts = Expressions clearly referring to situations rather than to one object/action. • Discourse = Socially based conversation where children listen and respond to another’s speech.
The Rules of Pragmatics – Using Language Appropriate To A Given Situation • Engage attention of listener. • Be sensitive to listener’s feedback and respond clearly. • Adjust speech to the characteristics of the listener (e.g. age, culture, social background). • Adjust speech to suit situation (e.g. church) • Learn to listen. • Evaluate own and conversational partner’s messages.
Making conversation at 2yrs • 2-year-olds… • Addressed listeners during interaction • Directed communication to others when they could see each other. • Made close contact to topic/object of conversation. • Responsive to feedback. • (Wellman & Lempers, 1977)
Adjusting speech • 2-3-yr-olds used more repetitions and more attention-eliciting words (hello, look) when talking to baby siblings than to mothers. • (Judy Dunn & colleagues)
Children’s Limitations… • Less effective speakers when they must compete with other adults or children. • Less competent when speaking about • Absent objects • Feelings • Thoughts • Relationships
Learning to listen • Even 3-yr-olds can recognize ambiguous messages and respond appropriately. Revelle et al (1985) • When 3- and 4-year-olds heard ambiguous requests (e.g. Bring me the refrigerator)…. • Many understood that request was problematic and requested more information (e.g. How? It is too heavy)
Bilingualism / Multilingualism LANGUAGE DEVELOPMENT
A few consequences of bilingualism… • Learning of each language may be slower, vocabularies of each language smaller. • Can use distinct sounds from each language to deal with cognitive load from learning two languages. • Skillfulness in 2 languages – better concept formation, flexible thinking.
Crib bilingualism… • Bilingual exposure in early infancy enhances the ability to monitor and switch between competing tasks. • Having to inhibit knowledge about one language while learning another language promotes executive control. • Better cognitive flexibility and executive control – better ability to monitor, repair, and reinterpret sentences.
Types of intelligence Fluid Crystallized Individual’s acquired knowledge; useful for dealing with problems that are similar to those already encountered. Increases with age. • Ability to deal with new and unusual problems, likely to be a fast learner. • Decreases with age. • More susceptible to bodily changes.
Sternberg’s Triarchic Theory of Intelligence • 3 major components – • Information-processing skills: Encode, store, and retrieve info. • Experience with given task: Exposure & practice with particular intelligence task. • Ability to adapt to demands of context: Adapt to requirements, select situation to meet abilities & needs.
Sternberg’s Theory of Successful Intelligence • Ability to meet own goals and those of his/her society. • 3 abilities: • Analytical: reasoning about best answer to a question. • Creative: devising new ways of addressing issues and concerns. • Practical: skills used in work, family life, social/professional interactions.
Gardner’s Theory of Multiple Intelligence • 8 kinds of intelligence: • Linguistic (e.g. poet, teacher) • Logical-Mathematical (e.g. scientist) • Spatial (e.g. engineer, artist) • Musical (e.g. musician, composer) • Bodily-Kinesthetic (e.g. dancer, athlete) • Intrapersonal (e.g. novelist, actor) • Interpersonal (e.g. psychotherapist) • Naturalistic (e.g. biologist)
Application to formal education? • Gardner & Sternberg’s Project Zero Practical Intelligence for School Program (PIFS) • Positive effects on motivation, achievement, behavior.
PIFS • Students work through lessons that develop their understanding of their own strengths and interests; • The purposes of various school tasks (why is there homework and how is it similar to what adults do?); • The demands of different subject areas (how is studying for a math test different from studying for social studies?); • The many steps involved in school tasks (such as making plans and using resources); and • The importance of self-monitoring through reflection (in journals and discussions).
IQ (Intelligence Quotient) Index of a way a person performs on a standardized intelligence test relative to the way others of the same age perform. Intelligence Testing
Flanagan & Harrison, 2005 • Predict academic performance • Predict performance on the job • Assess general adjustment & health Problem with IQ Test Questions… • Are they accurate? • Are they culturally sensitive?
