Development
Five Properties of Language
1. Creative or novel– We do not memorize sentences, we create them as
we go along2. Highly structured or patterned3. Meaningful– Meaning is derived from the words used and their
order4. Referential– Refers to and describes things in the real world
5. Interpersonal/communicative– Involves the thoughts of more than one person at a
time
How Children Learn Language• It had been theorized that children learn by
imitation and correction with reinforcement• However:– Children produce new sentences that they have
not heard before, often incorrectly – Parents do not always correct
grammatical/linguistic mistakes– A child who creates grammatically incorrect new
sentences may still be told “very good” if he or she has just started talking or is using new words
How Children Learn Language
• “Motherese”– Adults tend to use “motherese” when speaking to
babies• Higher pitched, slower rate, exaggerated intonations• Pauses between sentences and words are better
defined
– Babies prefer motherese to adult conversational tones
How Children Learn Language Errors
• Children may over or under generalize the meaning of a word– Undergeneralization: Not realizing that “house”
refers to large houses as well as doll houses– Overgeneralization: Thinking that all men are
called “Daddy”
How Children Learn Language
• At 16 months old, children generally use one word utterances, but we interpret them as having a full sentence’s worth of intended meaning
• For example, we would assume that a child is asking for a cookie, not merely announcing the presence of a cookie.
How Children Learn LanguageIn studies, if a 16 month old hears, “Oh look! Big Bird is
tickling Cookie Monster” they look to the appropriate picture indicating that they do understand prepositions
How Children Learn Language Sensitivity to Patterns
Children learn that syntax provides clues as to what type of word is being used
In a study using 3 – 4 year olds:• If asked, “In this picture, can
you see sebbing?” children made the same movement with their hands
• If asked, “In this picture, can you see a seb?” children pointed to the container
• If asked, “In this picture, can you see any seb?” children pointed to the contents of the container
How Children Learn LanguageSensitivity to Patterns
• 8 month old babies heard a two minute tape recording that sounded like “bidakupadotigolabubidaku”
• There were no differences in how syllables were stressed, and no pauses
• The experimenters had decided that “bidaku” would be a word– “bida” would always be followed by ku– “daku” could be followed by anything
How Children Learn LanguageSensitivity to Patterns
• In subsequent recordings, the babies showed no evidence of surprise if they heard “bidakubidakubidaku”
• They did show surprise if they heard “dakupadakupadakupa” – They had heard the same syllables before, but
that combination was new and therefore a new word
How Children Learn LanguageSensitivity to Patterns
• The sensitivity to patterns may cause difficulties in a language like English
• The suffix “ed” usually means past tense• Generalizing the pattern would yield “I goed” “I
eated” and “I drinked”• Usually “s” means plural, yielding “foots” and
“mouses”
This is called overregularization
How Children Learn Language
• Every language has a limited number of phonemes (the smallest significant unit of sound in a language)
• The phonemes vary across languages
How Children Learn Language
• Ex. in English, the difference in pronunciation between L and R is important– “Lob” and “Rob” sound similar, but have different
meanings – In Japanese, there is no linguistic difference
between L and R, and therefore Japanese people often have trouble hearing a difference between the sounds or producing it
How Children Learn Language
• At birth, we have the ability to perceive all of the phonemes across different languages but we lose that ability if it is not used– By 6 months the ability has started to diminish– By 12 months it’s mostly gone
Selective Looking ExperimentsMarcus’s Research
• A baby sits on his or her caregiver’s lap in front of two video screens, one on the left, one on the right
• The caregiver is blindfolded so he or she cannot direct the baby’s attention to either screen
• Sound plays from a speaker, and a moving image appears on the left or right screen
Selective Looking Experiments
Marcus’s Research
• In the first part of the experiment, the baby is introduced to a series of nonsense syllables following an ABB pattern – i.e., “la ti ti” “do fe fe”
• As the sound plays from the left or right speaker, an image appears on the corresponding screen
• At first, the baby finds this interesting and turns to look at the appropriate screen
• When the baby gets used to the setup (habituated) he or she looks at the screens less often and for shorter periods of time
Selective Looking ExperimentsMarcus’s Research
• In the second part of the experiment, phonemes from another language are used
• The phonemes follow the same ABB pattern or an ABA pattern– i.e., “la ti la” “do fe do”
• When the phonemes follow the familiar pattern, it is uninteresting and the baby does not attend to the monitor
• When the phonemes follow the ABA pattern, it is novel and the baby does attend to the monitor
Selective Looking Experiments
Marcus’s Research
• The difference in the baby’s interest in the ABB vs. ABA patterns with foreign language phonemes show that the baby can hear the sounds as being different from each other
