4. First Language Acquisition The process of acquiring language among children is also known as emergence of language. The outcome of this process is a grammar. 2 reasons for saying that the development of linguistic skills involve the acquisition of a grammar. Source: O’Grady, W. & Cho, S. W. (2012), pp. 326-359 Wong Bee Eng FBMK UPM 4

5. First Language Acquisition 1. Adult users of language are able to produce and understand an infinite number of novel sentences – a basic requisite of normal language use - which can only happen if they have acquired a grammar as children. 2. Another indication that children acquire a grammar, i.e. rules of a grammar, comes from their speech errors. These provide clues about how the acquisition process works. Source: O’Grady, W. & Cho, S. W. (2012), pp. 326-359 Wong Bee Eng FBMK UPM 5

6. First Language Acquisition  Since adults don’t talk the way children do, the errors made by children tell us that children don’t merely imitate what they hear.  They create rules of their own to capture regularities that they hear in their input.

7. First Language Acquisition Linguists and psychologists study – identify and describe – the process of language acquisition by analyzing the emergence grammatical system of children. They look to the study of the following to help them: phonology morphology syntax Source: O’Grady, W. & Cho, S. W. (2012), pp. 326-359 Wong Bee Eng FBMK UPM 7

8. First Language Acquisition Wong Bee Eng FBMK UPM 8 Methods Most studies focus on children’s early utterances, the order in which they emerge, the kinds of errors made. 2 Complementary Approaches of data collection The naturalist approach The experimental approach Source: O’Grady, W. & Cho, S. W. (2012), pp. 326-359

9. First Language Acquisition Naturalistic approach: usually longitudinal Observe and record children’s spontaneous utterances, e.g. a. diary study (researcher keeps daily notes on a child’s linguistic progress) b. Regular taping sessions, often at biweekly intervals, an hour at a time, of the child interacting with his/her caregivers. Detailed transcripts are made for subsequent analysis. (see CHILDES – Child Language Data Exchange System) Source: O’Grady, W. & Cho, S. W. (2012), pp. 326-359 Wong Bee Eng FBMK UPM 9

10. First Language Acquisition Naturalistic studies Advantage: Provides a lot of information of the emergence of grammar. Disadvantages: Certain structures and phenomena may occur rarely in children’s daily speech making it difficult to gather enough data to test hypotheses or draw firm conclusions. Speech samples from individual children capture only small portion of their utterances at any given point in development (15% or less). Wong Bee Eng FBMK UPM 10

11. First Language Acquisition Experimental Approach: usually cross- sectional Researchers make use of specially designed tasks to elicit linguistic activity relevant to the phenomenon they wish to study. The child’s production is used to formulate hypotheses about the type of grammatical system acquired at that point in time. Wong Bee Eng FBMK UPM 11

12. First Language Acquisition Types of experimental studies  Use tasks that test children’s comprehension (e.g. judge truth statements made about particular pictures or situations), production (such tasks may be difficult for children), or imitation skills (such tasks can provide important clues about grammatical development) Wong Bee Eng FBMK UPM 12

13. First Language Acquisition Experimental studies Advantage: they allow researchers to collect data of a very specific sort about particular phenomena or structures. Disadvantages: Difficult to design such experiments. Children’s performance may be affected by extraneous factors, e.g. inattention, shyness, or a failure to understand what is expected of them. Wong Bee Eng FBMK UPM 13

14. First Language Acquisition Better to use naturalistic observation together with experimental techniques. Together they have advanced our knowledge of the process. Wong Bee Eng FBMK UPM 14

17. Wong Bee Eng FBMK UPM 17 c. Early phonetic processes 1.Syllable simplification – systematic deletion of certain sounds in order to simplify syllable structure. e.g. delete [s] stop  [t ɒ p] 2. Syllable deletion – deletion of unstressed syllables. e.g. spa ghe tti  [g ǝ ]

18. 3.Substitution processes – systematic replacement of one sound by an alternative that the child finds easier to articulate stopping e.g. sing  [t I ŋ] change: s  t fronting e.g. ship  [s I p] change: ʃ  s gliding e.g. lion  [ja I n] change: l  j denasalization e.g. room  [wu:b] change: m  b Wong Bee Eng FBMK UPM 18

19. Wong Bee Eng FBMK UPM 19 4. Assimilation The modification of one or more features of a segment under the influence of neighbouring sounds - Initial consonants voiced in anticipation of the following vowel. e.g. tell  [del] - To maintain the same place of articulation for all of the consonants or vowels in a word. e.g. doggy  [g ɒ gi:] or [d ɒ di:]

20. Vocabulary Development By 18 months, the child has a vocabulary of 50 words or more. Common words refer to  Entities – people, food/drinks, animals, clothes, toys, vehicles, other (e.g. bottle, key, book)  Properties – e.g. hot, dirty, here, there  Actions – e.g. up, sit, see, eat, go, down  Personal-social – e.g. bye, no, yes, please, thank-you Wong Bee Eng FBMK UPM 20

21. Noun-like words – largest class, followed by verb- like words, and adjective-like words. Over the next few years – children learn between 10- 12 words a day. By age 6, they have 13,000-14,000 words. Wong Bee Eng FBMK UPM 21

22. 3 Strategies for acquiring word meaning The Whole Object Assumption A new word refers to a whole object The Type Assumption A new word refers to a type of thing, not just to a particular thing. The Basic Level Assumption A new word refers to objects that are alike in basic ways (appearance, behaviour, etc.) Wong Bee Eng FBMK UPM 22

23. Contextual clues Ability of the child to make use of contextual clues to draw inferences about the category and meaning of new words. e.g. children can use the presence or absence of determiners to differentiate between names and common nouns. Wong Bee Eng FBMK UPM 23

24. Meaning Errors Overextensions The meaning of the child’s word is more general or inclusive than that of the corresponding adult form. e.g. the word dog is frequently overextended to include horses, cows, etc. Underextensions The use of lexical items in an overly restrictive fashion. e.g. the word kitty might be used to refer to the family pet, but not to other cats. Wong Bee Eng FBMK UPM 24

25. Verb meanings e.g. the word fill means pour into rather than make full. Such errors disappear as children realize the actual meaning of fill. Wong Bee Eng FBMK UPM 25

26. Dimensional terms Terms describing size and dimensions are acquired in a relatively fixed order. 1 st group of adjectives – big, small (can be used for talking about any aspect of size – height, area, volume, etc.) 2 nd group - tall, long, short, high, low (can only be used for a single dimension – height-length) Other modifiers – thick-thin, wide-narrow, deep-shallow – more restricted in use – describe secondary or less extended dimension of an object. Wong Bee Eng FBMK UPM 26

27. Wong Bee Eng FBMK UPM 27 Morphological Development Overgeneralizations or Overregularizations e.g. *mans *runned *felled

28. Wong Bee Eng FBMK UPM 28 Developmental Sequence A.Typical developmental sequence for non-lexical morphemes 1.-ing 2.plural –s 3.possessive – ’s 4.the, a 5.past tense –ed 6.third person singular –s 7.auxiliary be

30. Word formation processes Derivation and compounding emerge early in the acquisition of English. First derivational suffixes are the most common ones in adult language. Children’s creativity with compounds shows a preference for building words from other words. Ending Meaning Word /-ness/ statesadness /-ing/ activityrunning /-er/ doer /-ie/ diminutive teacher doggie Child’s word Intended meaning car-smoke N-Nexhaust firetruck-man N-Nfire fighter cup-egg N-Nboiled egg Wong Bee Eng FBMK UPM 30

31. Wong Bee Eng FBMK UPM 31 The 2 processes that apply most freely in English, i.e. the formation of a noun by the addition of the agentive affix –er to a verb (a derivational process) and compounding, were the first to emerge. e.g. A person who swims is a ___________. A house for a dog is a ___________.

32. Wong Bee Eng FBMK UPM 32 Syntactic Development I. The one-word stage A child begins to produce one-word utterances (holophrases = whole sentences) between the ages of 12 months and 18 months.

33. Wong Bee Eng FBMK UPM 33 A basic property of these one-word utterances is that they can be used to express the type of meaning that would be associated with an entire sentence in adult speech. E.g. dada can mean I see daddy. Children seem to choose the most informative word that applies to the situation at hand.

34. Semantic relations in children’s one-word utterances Wong Bee Eng FBMK UPM 34 Semantic relation UtteranceSituation Agent of an actiondadaas father enters the room Action or statedownas child sits down Themedooras father closes the door Locationhereas child points Recipientmamaas child gives mother something Recurrenceagainas child watches lighting of a match

35. Wong Bee Eng FBMK UPM 35 II. The two-word stage a.Within a few months of their first one-word utterances, children begin to produce two- word mini-sentences. b. The vast majority of two-word utterances employ an appropriate word order, suggesting a very early sensitivity to this feature of sentence structure.

36. Some patterns in children’s two-word speech Wong Bee Eng FBMK UPM 36 Utterance Intended meaningSemantic relation Baby chair The baby is sitting agent-location on the chair. Doggie bark The dog is barking. agent-action Hit doggie I hit the doggie. action-theme Sam water Sam is drinking water. agent-theme Daddy hat Daddy’s hat. Possessor-possessed

37. Wong Bee Eng FBMK UPM 37 III.The telegraphic stage Early sentences are mainly words from the major grammatical categories of nouns, verbs, and adjectives. The missing elements are determiners, prepositions, auxiliary verbs, and the bound morphemes that go on the ends of nouns and verbs. These are the grammatical morphemes.

38. Wong Bee Eng FBMK UPM 38 It is possible that these grammatical morphemes are omitted because they are not essential to meaning. Another reason is children have cognitive limitations on the length of utterance they can produce, independent of their grammatical knowledge.

39. Wong Bee Eng FBMK UPM 39 Given such limitations, children may sensibly leave out the least-important parts. Such words may not be stressed in adults’ utterances and therefore children may be leaving out unstressed elements. Other researchers also suggest that children’s underlying knowledge does not include grammatical categories that govern the use of the omitted forms.

40. Wong Bee Eng FBMK UPM 40 IV. Later development The development of different sentence forms

41. Wong Bee Eng FBMK UPM 41 Individual Differences in Grammatical Development Children differ in both the rate and course of grammatical development. Differences in rate are the most obvious. Some children produce multiword utterances at age 18 months, whereas others do not start combining words until they are 2 years old. Differences in the kinds of multiword utterances children produce – some children rote-learn these as wholes; other children combine separate words from the start.

42. Wong Bee Eng FBMK UPM 42 Some children pay more attention to syllables and phonemes; others pay more attention to the overall prosodic “tune” (Peters, 1997). The tune approach or holistic approach or top-down approach, results in many unanalysed chunks. e.g. Idontwanna (for I don’t wanna) The other approach is the analytical or bottom-up approach. In this approach, children break down speech into smaller units and then combine them.

43. Wong Bee Eng FBMK UPM 43 Most children use both top-down and bottom-up strategies, and most children include both unanalyzed chunks and smaller units in their early sentences. However, children vary in how much they rely on one strategy versus the other, and the route to syntax some children take seems to be extremely holistic or extremely or extremely analytic (Hoff, 2001: 223).

44. What makes language possible? The role of adult speech - Caregive speech The role of feedback – recasts The role of cognitive development The role of inborn knowledge Wong Bee Eng FBMK UPM 44

45. Is there a critical period? Normal linguistic development is possible only if children are exposed to language during a particular time frame or critical period. Evidence for the existence of such a period – from studies of individuals who do not experience language during the early part of their lives, e.g. Genie. Wong Bee Eng FBMK UPM 45
