2Motivation Methods
3Motivation
- Previous studies of grammatical development in
SLA are nonintersecting sets of studies - The examination of formal features
- morphological development
- syntactic development
- The investigation of learners overall progress
- global L2 proficiency
- across various levels of learners
4Morphological development
- Dulay and Burt (1973, 1974a, 1974b) for children
- Bailey, Madden and Krashen (1974) for adults
- Krashen, Houck, Giunchi, Bode, Birnbaum, and
Strei (1977) for adults - Kayfetz (1982) for adults
5Syntactic development
- Relative clausesSchachter (1974) and Gass (1980)
- The pro-drop parameterWhite (1985) and Phinney
(1987) - Preposition stranding and pied pipingMazurkewich
(1984) and Bardovi-Harlig (1987)
6- Learners overall progress
- Larsen-Freeman (1973, 1983), Larsen-Freeman
- et. al (1977), Gaies (1976), and Monroe
(1975) - The widely used measure
- the average number of words per error-free
T-unit
Syntactic complexity
Accuracy
7The present study intends to
- examine the relationship between syntactic
development, or complexity, and overall accuracy
evidenced in the written English of advanced
adult language learners. - combine aspects of these previous studies in
that it seeks to describe these three aspects,
morphology, syntax, and error measurement in
other words, overall accuracy with regard to the
distribution of errors.
8 Participants
- 30 advanced EFL learners
- 5 native languages
- Learners were further divided into Pass/Non-pass
subgroups
Table 1. Participants
9Procedure
- Compositions written as part of the Indiana
University Placement Exam - Allotted time 45 minutes
- Topics nontechnical in nature
- The reason for using written texts instead of
oral - production
- more likely to be evaluated in detail
- comparable to the oral samples
- exhibiting similar evidence of development
10Data Analysis
- The essays were scored along two parameters
- Syntactic complexity
- the average number of clauses per T-unit
- Surface errors
- syntactic
- morphological
- lexical-idiomatic
11T-unit
- Devised by Hunt (1965)
- a minimal terminable unit
- one main clause with all the subordinate clauses
attached to it
12Lets practice together!
- one main clause with all the subordinate clauses
- attached to it
1. He likes to sleep and to catch frogs.
A simple sentence with a compound predicate ?
one T-unit
2. Hes Shirins cat whose name is Alyosha.
A complex sentence ? one T-unit
3. He likes to eat, but he hates fruit.
A compound sentence consisting of two main
clauses ? two T-units
13Is this a syntactic, a morphological or a
lexical-idiomatic error?

lot of countries. tense, preposition, plural
14Morphological errors
- include errors in inflectional morphology (i.e.
nominal morphology and verbal morphology), and
errors in determiners, articles and prepositions - the errors in derivational morphology were
recorded separately
15Is this a syntactic, a morphological or
a lexical-idiomatic error?
She loved me very much, so did I.
She loved me very much, and I loved
her. coordination
16Syntactic errors
- including errors of word order, errors resulting
from the absence of major and minor constituents,
and errors in combining sentences
17Is this a syntactic, a morphological or a
lexical-idiomatic error?
Since the date when oil have been explored, the
government of Saudi Arabia started to assess the
foundation for an industrial nation.
When oil began to be exploited, the government of
Saudi Arabia started to assess the foundation
for an industrial nation. tense,
lexical-idiomatic
18Lexical-idiomatic errors
- include lexical-idiomatic or vocabulary errors
19RESULTS
20The complexity data and the analysis of errors
show that the interlanguage of these advanced
learners -- in both groups -- exhibits relatively
strong syntax but incomplete and variable
acquisition of grammatical morphemes.
21Complexity
22pass non-pass ? similar complexity scores
- Both groups same lower range (1.6
clauses/T-unit) - Non-pass group higher upper complexity scores
(3.3 clauses/T unit) - Pass group (2.5 clauses/T-unit)
23Table 2. T-unit complexity scores for pass and
non-pass groups
24Different L1 backgrounds ? same frequency of
syntactically complex T-units

36DISCUSSION
37Two possible interpretations of these results
38Communicative
- Acquisition is driven by meaning and learner
perception of salience - Burt Kiparskys (1972) division of errors into
- Global overall sentence organization, including
word order and missing, incorrect, or misplaced
sentence connectors - Local single elements or constituents, include
nominal and verbal morphology, articles, and
auxiliaries
39How to apply to this study
?
Global
Syntactic
?
Local
Morphological
This interpretation is supported by Van Pattens
(1984, 1985) findings that learners process first
for meaning and then for form
40Which group (pass/non-pass) is more
communicatively successful in the acquisition of
lexical and idiomatic items?

non-pass groups ( of total)
The pass group!
41A problem for the communicative interpretation
Errors in verb tense Subjects made more errors
in tense use (tense switching) than in tense form
(tense formation, subject-verb agreement)
Possible reason?
Transfer-of-training from instruction that
emphasizes formal accuracy over meaning and use
42Formal
- (driven largely by findings from FLA)
- Long (1987) and Goldin-Meadow (1982)
- Learners select certain features of language
from the input and acquire those features earlier
and/or better
syntax
In the case of this study, _______seems to
precede __________.
morphology
43Resilient Fragile properties
Goldin-Meadow (1982) divides language into
resilient and fragile properties Argues from a
critical period perspective
Resilient properties weeds
Fragile properties hothouse orchids
44Resilient Fragile Properties comparison
- Based on data from deaf children who developed
home sign and children who grew up in
linguistically deprived conditions - Genie (Curtiss, 1977)
- Newport, et al. (1977)
45Resilient Properties
- Word-order production rules, constituent
structure, recursion (the means for expressing
more than one proposition in a single sentence) - Can still be acquired after critical period or
under conditions of deprivation
46Fragile properties
- Movement rules, pro-forms, auxiliary structures,
etc.) - Can no longer be acquired after critical period
or under conditions of deprivation
47In this study..
?
Resilient
Syntactic
?
Fragile
Morphological
- Resilient (syntactic) features of language are
not influenced by background variables such as - L1 background, learning history, type of input,
or pass/non-pass
- Fragile (morphological) features account for most
of the errors across groups and are more
susceptible to influence from background variables
48Directions for future research
Four-way comparison between ESL and EFL child and
adult learners regarding fragile features
49Questions motivating this four-way comparison
- Can fragile properties be learned after the
critical period?
- Can the critical period (or sensitive period)
hypotheses account for the lower morphological
accuracy among advanced learners?
50Question about this four-way comparison
If the answers to the previous questions are yes,
then do other variables such as ESL vs. EFL play
a role?
NO!
51The biggest challenge to both the communicative
and the formal interpretations
Slobins (1982) hypothesis that individual
languages are balanced in terms of syntactic vs.
morphological difficulty(also based on FLA data)
Crosslinguistic study comparing early child
language acquisition among speakers of English,
Italian, Serbo-Croatian, Turkish, and Japanese
52Motivation for Slobins study
- Naturalness hypothesis
- (Slobin calls it an Anglo-centrist or
Indo-european-oriented position) - (ie Bloom, 1973)
- claims that children learning English acquire
syntax before morphology because word order is a
natural reflection of the order of thought
53But..
- Slobins study shows that children learning
Turkish (a flexible, pragmatic word-order
language in which grammatical functions are
encoded in bound morphemes) acquire morphology
before syntax and show overall - faster and greater language acquisition in early
stages than children learning strict word-order
languages such as English and Italian
54Reasons for Turkish childrens precocious
language acquisition
- (a selection of his reasons)
- In Turkish
- Morphology is highly regular
- Distinct morpheme for each grammatical function
- Morphology is consistent and obligatory, never
optional - Morphology is bound to the noun
- Morphemes are syllabic and stressed
55Also
- Turkish children have the advantage of following
local cues (decoding inflections of a single word
regardless of position in sentence) rather than
global cues that require learners of word-order
languages to process the entire sentence to
determine function of words
56However.
- At later stage of L1 acquisition, Turkish
children are slower than learners of
Indo-European languages with regard to features
such as relative clause constructions, which
require complex syntax in Turkish
57- Slobins findings support hypothesis of equal
difficulty of acquisition across languages - in some languages, morphological ease (or
regularity) is counterbalanced by syntactic
complexity (ie Turkish) whereas in other
languages, syntactic ease (or regularity) is
counterbalanced by morphological difficulty (ie
English)
58How does this pertain to the current study?
- The authors suggest that English may be easy
__________ but difficult _____________ .
syntactically
morphologically
Communicative and formal interpretations are
learner-based, whereas Slobins position is
language-based.
59- In order to test learner-based vs. language-based
positions, the authors suggest a study comparing
adult learners of Turkish (and other languages)
from a variety of L1 backgrounds
60Learner-based vs. language-based
- Support for learner-based position
- Learners have greater facility acquiring global
or resilient features despite regularity of
Turkish morphology - Support for language-based position
- Learners acquire Turkish morphology early,
accurately, and uniformly (as do Turkish children
during FLA)
