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
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
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
Children Adults
Speed - +
Attainment + -
Phonology + -
Syntax +/- +/-
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
Becky H. Huang & Sun-Ah JunUniversity of California, Los Angeles
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
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
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.
Participants
LEARNER GROUPS
Child Arrival AoA=5-9
Adolescent Arrival AoA=12-17
Adult Arrival AoA=20-26
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
Findings
APPLICATIONS
1. For teaching children
2. For teaching adults
Pronunciation
Vocabulary
For teaching children
from
L2
different speakers
songs, stories, games, etc.
imitating the sounds
Pronunciation
to like
Vocabulary
needs to be taught
in context
meaning of the words should be clear
The context given through:
1. Pictures and flashcards
2. Stories
3. Games
4. Songs
For teaching adults
generate interests
give sensible tasks and activities
assist the short-term
goals
For teaching adults
Making the English Classroom a Supportive Language Environment
Encouragement
Trustworthiness
A variety of materials
and models
Comprehensible and
contextualized language
