Overview
  • Previous research on lexical chunks
  • Previous eye-movement studies
  • Design of a pilot eye-movement study
  • Data analysis
  • Design of a lexical chunk acquisition study

4
Previous research on lexical chunks
(1) Definition and terminology
  • Examples as a matter of fact in ___ point of
    view
  • Different terms prefabricated patterns (Hakuta,
    1974)
  • memorized sentences and lexicalized stems
    (Pawley Syder, 1983)
  • lexical phrases (Nattinger DeCarrico,
    1992)
  • lexical bundles (Biber et al, 1999)
  • formulaic sequences (Wray, 2002)
  • Definition a sequence, continuous or
    discontinuous, of words or other elements,
    which is, or appears to be, prefabricated that
    is, stored and retrieved whole from memory at the
    time of use, rather than being subject to
    generation or analysis by the language grammar.

Previous research on lexical chunks
(2) Native-like proficiency and lexical chunks
  • Pawley Syder (1983)
  • Native-like selection
  • E.g. 1a. I desired you to become married to me.
  • 1b. Your marrying me is desired by me.
  • Native-like fluency
  • limitation of working memory (Miller, 1956)

6
Previous research on lexical chunks
(3) Detection of formulaicityNSs judgments
  • Fernando (1996)
  • compositeness
  • institionalization E.g. take the bull by the
    horns
  • semantic opacity
  • Foster (2001)difficulty of deciding formulaicity
  • NSs reported difficulty in knowing where exactly
    to mark boundaries of some lexical chunks (p.
    84).

Previous research on lexical chunks
(4) Detection of formulaicitycorpus-derived
sequences
  • Biber, Conrad, and Cortes (2004)
  • More stance (e.g. I dont know if) and discourse
    organization (e.g. what do you think) sequences
    were used in classroom instruction than in
    textbooks.
  • Schmitt, Grandage, and Adolphss (2004) argument
  • e.g. I see what you
  • is one of the most

8
Previous research on lexical chunks (5) Lexical
chunks in L2 acquisition
  • Hakuta (1974)
  • (1) patterns with the copula (e.g. Why these
    are dirty?)
  • (2) segments do you in questions (e.g. What do
    you drinking, her?)
  • (3) segments how to in how-questions (e.g. I know
    how to read it this)

9
Previous research on lexical chunks
(6) Processing of lexical chunks in L2
acquisition
  • Underwood, Schmitt, and Galpin (2004)
  • Lexical chunks seemed to be processed as single
    units by NSs, and not by NNSs.
  • E.g.
  • from the point of view

Overview
  • Previous research on lexical chunks
  • Previous eye-movement studies
  • Design of a pilot eye-movement study
  • Data analysis
  • Design of a lexical chunk acquisition study

11
Previous eye-movement studies (1) What can we
know from observing eye movements?
Frenck-Mestre, C. (2005)
The factory fixed during the night opened its
door very early
12
Previous eye-movement studies (2) An example
13
Previous research on lexical chunks (3) Relevant
studiescontextual constraints
  • Assumption words which are constrained by
    linguistic contexts offer redundant information
    and thus get fewer and shorter fixations in
    reading.
  • Ehrlich Rayner (1981)

Overview
  • Previous research on lexical chunks
  • Previous eye-movement studies
  • Design of a pilot eye-movement study
  • Data analysis
  • Design of a lexical chunk acquisition study

15
Design of a pilot eye-movement study (1) Purpose
  • The pilot study aims at investigating whether
    lexical chunks are processed and stored as single
    units in human minds.
  • Native speakers
  • Non-native speakers

16
Design of a pilot eye-movement study
(2) Participants
  • Native speakers two English-speaking native
    speakers.
  • Non-native speakers
  • 11 EFL learners in Taiwan, studying in the MS
    program in the English Department of Tamkang
    University.

(3) Materials
Underwood, Schmidt and Galpins (2004) study
twenty chunks

Design of a pilot eye-movement study
(5) Hypothesis
  • E.g. beat around the bush
  • When the native speaking subjects read the
    lexical chunks, they will have shorter and fewer
    fixation durations on the terminal words of these
    sequences, while the L2 subjects will not.

Overview
  • Previous research on lexical chunks
  • Previous eye-movement studies
  • Design of a pilot eye-movement study
  • Data analysis
  • Design of a lexical chunk acquisition study

20
Data analysis (1) Numbers of fixations
21
Data analysis (2) Mean fixation durations
22
Data analysis (3) Findings
  • Native speakers had fewer and shorter fixations
    on terminal words in lexical chunks, while
    non-native speakers did not.

(2) Can the processing of lexical chunks be
facilitated through reading?

(3) Can explicit knowledge of chunks be
converted into implicit use?
