3. Language acquisition Def.: First language acquisition refers to the acquisition of one’s mother tongue during the first 6 to 7 years of one's life (from birth to the time when children start school).

4. Language acquisition for children consists of achieving control in four main areas: • A set of syntactic rules determining how phrases are formed out of words and sentences out of phrases. • 2) A set of morphological rules determining how words are built up out of morphemes. • 3) A set of phonological rules determining how words are pronounced. • 4) A set of semantic rules determining the meaning of words, phrases and sentences.

5. Maturation • no evidence for any conscious and systematic • teaching of language • environment changes, because the child's behaviour • changes • most important differences between pre- and • postlanguage phases originate in the individual • > maturational processes • differ in each individual so that it is very difficult to • explore

6. Hallmarks for maturationally controlled emergence of behaviour • regularity in the sequence of appearance of given milestones • opportunity for environmental stimulation remains relatively constant, each infant makes different use of these opportunities • emergence of behaviour before it is of immediate use to the individual • clumsy beginnings are not signs of goal-directed practice

7. Emergence of Speech and Language • onset of speech > gradual unfolding of capacities • speech milestones and motor-developmental • milestones occur together but it is no logical necessity • independent from articulatory skills • can babble but cannot form simple utterances • >psychological retarding factor in language acquisition, not a physical one

8. Emergence of Speech and Language • at the age of three speech skills are fully developed, • other mechanical skills not • language comprehension comes before the language production

9. Emergence of Speech and Language • 12 weeks > cooing: squealing-gurgling sounds, • vowel- like in character • 6 months > cooing changes into babbling, • on-syllable utterances like ma, mu or da • 12 months > signs of understanding, identical sound • sequences are replicated, mamma or dadda • 18 months > definite repertoire of words, more than • 3, less than 50, no attempt to communicate, no • frustration for not being understood, no spontaneous • two-item phrases

10. Emergence of Speech and Language • 24 months > more than 50 words, spontaneous two- • item phrases, own creations, interest in language • 30 months > new vocabulary every day, • communicative intent, frustrated if not understood, • rarely verbatim repetitions, understand everything, • intelligibility not good yet • 3 years > 1000 words, intelligible even to strangers, • grammatical complexity similar to colloquial adult • language • 4 years > language well-established

11. Acquisition of morphemes: Research of uncontrolled spontaneous speech has shown that: The developmental order of the morphemes (in, on, third person regular/irregular articles a.s.o.) is quite constant > the same is true of grammatical devices in general BUT The rate of development varies greatly between different children

12. Communication Pressure • Is there a pressure in communication that forces • children to replace ill-formed utterances by well-formed • utterances? • investigation with questions, negatives and tags • showed that there is no communication pressure • ill-formed utterances were understood perfectly well, • meaning became clear

13. Contingent approval • the approval or disapproval has no influence on the syntax, it depends on the truth value of utterances

14. Conclusion • no conscious or systematic teaching of language • independent from mechanical skills of the child • no communication pressure or contingent approval

15. Division between First and Second Language Acquisition: • The ability to acquire a language with the competence of a native speaker diminishes around puberty due to • general inflexibility of the brain caused by fixing of • various functions of parts of the brain • 2. hormonal changes during puberty having the same • effect

17. B.F. Skinner • American psychologist (1904-1990) • amongst others he wrote a book on verbal behaviour • in 1957 • his thesis is that external factors such as present • stimulation and reinforcement are crucial for the First • Language Acquisition of a child

18. B.F. Skinner • therefore children learn the rules of language by • imitating what they are been presented and taught in • daily life • Skinner thinks that children learn to produce • grammatically correct sentences because they are • positively reinforced and corrected by parents or other • adults • the learning of a child’s first language is similar to any • other learned behaviour

20. Introduction • Importance of Experience  General Information • Role of experience in language learning • General Problems from Learning from Observations • Two Experiments • Conclusion

21. Importance of Experience • To know a language = to know the relations between sounds and their meanings • Relations vary in different languages • - English /si/ means: “gaze with the eyes“ • - Spanish /si/ means “Yes“ •  Special experience is needed

22. Role of experience in language learning • Experiment: language learning by blind children • the blind seem to confront a world quite different from our own • Blind children have another context for learning words and sentences than sighted children • Question: How much differs the language learning?

23. General Problems from Learning from Observations • Too many encodings of experience are available • False Experiences • The problem of abstract meanings

24. Too many encodings of experience are available • Normally learners are exposed to objects, scenes, and • events as they listen to the stream of speech • Problem: no direct connection between the “meanings“ • and the objects, scenes, and events • Example: cat on the mat, the mat under the cat, and • the mat and the cat on the floor  same meanings  • difficult for children to understand

25. False Experiences • A child is inspecting a scene while the adult is • speaking of something else •  false pairing • Example: Mother says: “Time for your nap“ while the • child inspects a cat on the mat

26. The problem of abstract meanings • Many words have no direct connection with sensory- • perceptual experience • Example: • - Simple verbs as “get“ or “put“ • - Simple nouns as “fun“ or “pet“ • - Simple adjectives as “fair“ or “good“

27. Experiment 1: Does look mean “touch“to the blind child? • Setting: • - Kelli and sighted control children were tested in a familiar room • - Experimenter gives commands and waits for response • Subjects: • - Kelli: blind child, 36 months old • - 4 sighted blindfolded control children: 33 to 42 months • Commands: Look up, Look down, Look behind you, Look in front of you, Look over here by me, Look over there by Mommy

28. Experiment 1: Does look mean “touch“to the blind child? • Results: • - Kelli moved her hands to the commanded directions every time, but never moved her head • - In contrast each blindfolded child moved the head in the commanded direction •  For Kelli look means „touch“

29. Experiment 2: Look is more like “apprehend“ to the blind child • Results of Experiment 1 lead to a problem: Is there a • difference between look and touch for Kelli? • Further question: Does certain adjectival and adverbial • modifications of look produce still more distinctive • behaviours?

30. Experiment 2: Look is more like “apprehend“ to the blind child • Subjects: • - Kelli: 36 months old • - 4 blindfolded sighted children: 33-42 months • Commands: “look” or “touch” (using toys) • 1. With spatial modifiers: up, behind you, in that, under, here • 2. With intensity modifiers: real hard, gently, real good • 3. With instruments of contact: with your finger, foot, nose, mouth, ear

31. Experiment 2: Results of Kelli • In most cases she distinguished between touch and • look • 1. With spatial modifiers • - “look behind you”  she searched around in the are • behind her • - “touch behind you”  she touched her back • 2. With intensity modifiers • - “look real hard”  she rubbed the object all over • - “touch real hard”  she banged against the object

32. Experiment 2: Results of Kelli • 3. With instruments of contact • - “look with your mouth”  she held the object up to • her mouth • - “touch with your mouth”  she pressed her mouth • against the object • touch = “contact” •  look = “explore” or “apprehend”

33. Experiment 2: Results of the sighted children • These children also usually distinguished between • look and touch commands • Touch = “contact” •  Look = “visual”

34. Conclusion • Children do not acquire a language just by experience • and observation • But Kelli shows that experiences in different contexts • in early infancies lead to different meanings of words

35. Language and the mind Prof. R. Hickey WS 2007/08 The Child’s Learning of English Morphology Mouna Ksiksi (TN, Hauptstudium),Nazgül Songün (TN, Grundstudium)Aysel Sahan und Günes Yildirim(LN, Grundstudium)

36. The Child’s Learning of English Morphology • To discover what is learned by children exposed to • English morphology experimenters used nonsense • materials. • If children do have knowledge of morphological rules • how does this knowledge evolve? • To test the children’s knowledge they began with an • examination of the actual vocabulary.

37. The Child’s Learning of English Morphology • Tested areas: the plural/ the two possessives of the • noun/ the third person singular of the verb/ the • progressive/ the past tense/ the comparative and • superlative of the adjective • Children’s vocabulary at the first-grade level contains • a number of words that are made of a free morpheme • and a derivational suffix or of two free morphemes. • It also contains a number of compound words.

38. Materials and Procedure • The subjects included pre-school children, first- grade • children and adults. • Pictures to represent the nonsense words were drawn • on cards. • Subjects were asked to supply the missing word and • the item was noted phonemically. • After all of the pictures had been shown, the subjects • were asked why they thought the things denoted by the • compound words were so named.

39. Examples: 1. Plural ´ This is a wug. Now there is another one. There are two ……..´ 2. Past tense ´ This is a man who knows how to spow. He is spowing. He did the same thing yesterday. What did he do yesterday? Yesterday he ……. ´ 3. Compound words (e.g. football, airplane)

40. Results • The first question to be answered was whether there is • a sex difference in the ability to handle English • morphology at this age level. • There was not a significant difference between the • boys´ and girls´ performance, boys did as well as girls, • or somewhat better, on over half the items, so that • there was no evidence of the usual superiority of girls • in language matters.

41. Results • Age differnce • The first graders did significantly better than preschoolers on slightly less than half of these • Formation of the plural • The results of the first-grade children in the plural tasks were better than the results of the pre- school children. The significance level of difference was 5 percent.

42. Verb inflexions • The children were shown a picture of a man how to • *zib and were required to say he was *zibbing. Fully • 97% of the first graders answered this question • correctly • = there is just one allomorph of the progressive • morpheme, and the child either knows the –ing form or • not • The results of the past tense form shows that the • children can handle the /-t/ and /-d/ allomorphs of the • past. • Correct percentage answering: *binged: 78; *glinged: • 77. The older group did better than the younger group • on *binged.

43. Verb inflexions • All English verbs with the ending –ing are irregular: • 50% of the adults said *bang or *bung for the past • tense of *bing. 75% said *glang or *glung for the past • tense of *gling. Only one of the children said *bang and • one said *glang. • The percentages on *bing and *gling represent a • substantial grasp of the problem of adding • phonologically /-t/ o /-d/.

44. Verb inflexions • *spow: several children retained the inflexional /-z/ • and said spowzd, others repeated the progressive. • The children had to choose one or the other of the • allomorphs, and the drop to 52% correct represents • this additional complexity. • On *bodded they were 31% right, on rang only 17% • right. The older group was better than the younger • group.

45. Adjectival inflexion The child was shown dogs that were incrasingly *quirky and expected to say that the second is *quirkier than the first, and that the third was the quirkiest. Only one child was able to give the right answer. If the children failed to answer, the experimenter supplied the form *quirkier, and said “this dog is quirky This dog is quirkier. And this dog is the …?” Under this condtions 35% of the children could supply the –est form.

46. Derivation and compounding • They were asked what they would call a man who • *zibbed. • The adults said that a man who *zibs is • a *zibber, using the common agentive pattern –er. • Only 11% of the children said *zibber, • 35% gave no answer, • 11% said *zibbingman and • 5% said *zibman. • The rest of the answers were real words like acrobat or • clown.

47. Analysis of compound words • They were asked about some of the compound • words in their own vocabulary. The object of this • questioning was to see if children at this age are aware • of the separate morphemes in compound words.

48. Analysis of compound words 4 categories: 1. identity: “a blackboard is called a blackboard because it is a blackboard.” 2. statement of the object’s salient function or feature: “a blackboard is called a blackboard because you write on it”

49. Analysis of compound words 3. the salient feature happens to coincide with part of the name: “ blackboard is called a blackboard because it s black.” 4. there is the etymological explanation given by adults, it takes into account both parts of the word, and is not necessarily with some functional feature:”Thanksgiving is called Thanksgiving because the pilgrims gave thanks.”

50. Analysis of compound words • the greatest number of etymological responses (23%) • was given for Thanksgiving, wich is an item wich • children are taught. • despite this teaching, for 67% of the children • answered: Thanksgiving is called Thanksgiving • because you eat a lots of turkey. • shows the general nature of the private meanings • children may have about the words in their vocabulary.
