Critical Period Hypothesis (CPH)
A limited developmental period during which it ispossible to acquire L1 or L2 to native-like levels.
After this period learning decline
Birdsong (1999)

Sensitive Period Hypothesis (SPH)
A gradual period of declining
Allowance for greater variation in attainment
Long (1990)

CPH: discontinuity –a dramatic drop-off
SPH: sensitivity – a gradual decline in
learning

Larsen-Freeman and Long (1991): adults do quite wellon most tests measuring language learning speed.
=> Learning speed: adults > children
Age differences in language learning
![Page 8: Age Differences in Second Language Acquisition](https://reader034.fdocuments.us/reader034/viewer/2022042518/55a89fdd1a28abe2588b460e/html5/thumbnails/8.jpg)
Snow and Hoefnagle-Hohle (1978): adolescentsoutperformed children on tests given after threemonths of residence in Netherlands, but after tenmonths the children had caught of on mostmeasures.
=> Learning attainment: children > adults
Age differences in language learning
![Page 9: Age Differences in Second Language Acquisition](https://reader034.fdocuments.us/reader034/viewer/2022042518/55a89fdd1a28abe2588b460e/html5/thumbnails/9.jpg)
Age differences in language learning
Flege (1999, 2000, 2001) and otherresearchers: a foreign accent can occur evenwhen exposure begins at age 6 or earlier.
=> Phonology: children > adults

Johnson and Newport (1991): learners’ capabilitiesfor acquiring the syntax of a second languagedecline with age.
=> Syntax: children > adults
Bialystock (1997): age of onset of learning doesnot have significant effects.
=> Syntax: children >< adults
Age differences in language learning

Social psychology
not wanting to give up their accent
being unwilling to lower their ego
Cognitive factors
being too sensible when learning L2
Neurological changes
losing plasticity or flexibility
Language input
not being exposed to L2 input as well as children
Possible explanations for adults’ learning incapability

No single explanations can account for age differences in L2 learning.

AGE EFFECT ON THE ACQUISITION OF SECOND LANGUAGE PROSODY

![Page 16: Age Differences in Second Language Acquisition](https://reader034.fdocuments.us/reader034/viewer/2022042518/55a89fdd1a28abe2588b460e/html5/thumbnails/16.jpg)
Aims:
to explore the effect of age on the acquisition of L2prosody among Mandarin speaking immigrants
Prosody is the rhythmic and intonational
aspect of language.
Introduction
![Page 17: Age Differences in Second Language Acquisition](https://reader034.fdocuments.us/reader034/viewer/2022042518/55a89fdd1a28abe2588b460e/html5/thumbnails/17.jpg)
Is there an age effect on the ultimateoutcome of various aspects of secondlanguage prosody?
If so, which prosodic features are impactedby the age effect?
Research questions
![Page 18: Age Differences in Second Language Acquisition](https://reader034.fdocuments.us/reader034/viewer/2022042518/55a89fdd1a28abe2588b460e/html5/thumbnails/18.jpg)
Participants
10 native speakers (NS) of American English (control group)30 non-native speakers who:
spoke Mandarin (L1).
varied in their Age of Arrival (AoA, Range=5-27).
had received either none or only English instruction in a
regular foreign language classroom prior to their arrival.
held a college degree or were current college students.
have never been diagnosed with hearing problems, language
disorders, or learning disabilities.

Procedure
1. Ask the participants to read aloud a paragraph (69 words, 77 syllables, 4 sentences) twice at their natural pace.
2. Record

The significant influence of age on the acquisition of various aspects of L2 prosody:
Speech rate: Adults < NS
Adults < Children
Adults = Adolescents
Filtered speech rating: Adult < NS
Adolescents < NS
Adult < Child
Prosodic groupings: Adult < NS
Pitch accents: Adult < NS
