  1. DeCasper & Fifer Findings for Newborns 1. Prefer the human voice over "acoustically complex stimuli" (1176) 2. Can discriminate between speakers 3. Show a preference for their mother's voice with limited contact (at most 12 hours) DeCasper, Anthony J. and William P. Fifer. 26 February 1980. Of human bonding: Newborns prefer their mothers' voices. Science 208: 1174-1176.

  2. Characteristics of Caretaker Speech Prosody, etc. Higher in pitch More variable in pitch More exaggerated in intonational contours Slower Smoother pitch contours More rhythmic More pauses Content More repetitions More based in the here and now Carroll, David W. 1994. Psychology of Language, second edition. Pacific Grove, California: Brooks/Cole Publishing Company, p. 250.

  3. Gestures Showing Communicative Intent 1. Pointing at things (Assertion or request) 2. Showing things to parent (NOT to give) 3. Giving you things 4. Reaching 5. Showing off (Repeating things that get approval; dancing) Bates, Elizabeth, et al. 1979. Cognition and communication from nine to thirteen months: Correlational findings. In E. Bates, editor, The Convergence of Symbols: Cognition and Communication in Infancy. New York: Academic Press.

  4. Major Criteria for Assigning Intentionality 1. Waiting (for adult to pay attention) 2. Persistence 3. Development of alternative plans (flexibility) Carroll, David W. 1994. Psychology of Language, second edition. Pacific Grove, California: Brooks/Cole Publishing Company, p. 251.

  5. Gestures then Speech "To sum up, prelinguistic children use gestures to get the receiver's attention and to communicate. The transition to speech acts can then be viewed as learning how to do with words what already has been done without words." Carroll, David W. 1994. Psychology of Language, second edition. Pacific Grove, California: Brooks/Cole Publishing Company, p. 253.

  6. Milestones in Motor and Language Development—Simplified - 1 Age Motor Development Language, etc. months 1 Can distinguish consonants 3 Supports head when Smiles when talked to; prone; no grasp gurgles / coos (vowels) 4 Shakes rattle; Responds to human sounds : supports head turns head, eyes search 5 Sits with props Vowel-like cooing interspersed with more consonantal sounds

  7. Milestones in Motor and Language Development—Simplified - 2 Age Motor Development Language, etc. months 6 Sits; can bear weight; Cooing becomes reaches; grasps but no (reduplicated) babbling thumb opposition (babababa) 8 Stands holding on; Intonation patterns distinct; grasps with thumb can signal opposition emphasis and emotion; reduplication; communicative intentions

  8. Milestones in Motor and Language Development—Simplified - 3 Age Motor Development Language, etc. months 10 Crawls; side-steps holding Sound play: gurgling, on; bubble blowing; seems to try to imitate; pulls self up to stand differentiates between sounds heard 11-12 Variegated babbling (bigodabu) 12 Walks with help; seats self; More reduplication almost stopped mouthing (mama); signs of things some words and simple understanding; commands: Show me...

  9. Milestones in Motor and Language Development—Simplified - 4 Age Motor Development Language, etc. months 18 Grasp fully developed; 30-50 words; ONE-word phase; walks; sits on chair so-so; several syllable babbling; crawls down stairs intricate intonation pattern; backward; difficulty NOT frustrated when not building 3 cube towers understood; understanding progressing rapidly 24 Runs; sudden turns Vocabulary 50+ words; not good; stand and TWO-word phase; phrases sits easily; walks up own creation; increase in and down stairs communicative behavior

  10. Milestones in Motor and Language Development—Simplified - 5 Age Motor Development Language, etc. months 30 Jumps; stands on one foot; Fastest increase in vocabulary; good hand and finger frustrated if not understood; coordination; can build 6 two (even three or five) word cube tower; tiptoes a few utterances; intelligibility not steps very good; seems to understand everything directed to them 36 Tiptoes 3 yards; runs Vocabulary: 100 or so words; smoothly; makes turns 80% intelligible even to well; jumps 12 inches; strangers; grammar roughly can ride tricycle like adults, though still makes mistakes

  11. Milestones in Motor and Language Development—Simplified - 6 Age Motor Development Language, etc. months 48 Jumps over rope; hops on Language well established; one foot; catches ball in deviations from adult norm arms; walks line tend to be more in style than in grammar

First true words (12+ months) Carroll, David W. 1999. Psychology of Language, third edition. Pacific Grove, California: Brooks/Cole Publishing Company, p. 259.

  16. Possible Explanations for Children's Pronunciation Errors 1. Child cannot discriminate between the sounds 2. Child cannot produce the sounds 3. Overload of information processing capacity Carroll, David W. 1999. Psychology of Language, third edition. Pacific Grove, California: Brooks/Cole Publishing Company, pp. 261-262.

First Language Acquisition Strategies Referential Strategy Naming objects Vocabulary-building oriented: mostly nouns Language is individual words (bottom-up) Part to whole Expressive Strategy Social interaction More diverse vocabulary Language is whole sentences (top-down) Whole to part More likely to use 'dummy terms' Carroll, David W. 1999.
