Overview
  • naturalistic, experimental, elicited data
  • types of elicitation tasks and stimuli
  • an example construction-specific elicitation
    games for NPs
  • a generalised elicitation task
  • an example eliciting sentences with more than
    two NPs in German and Japanese
  • outlook

3
Naturalistic Data
  • other term spontaneous speech data
  • recording of ongoing communicative events (free
    play, dinner table conversation,)

4
Advantages
  • age-independent
  • no special task-demands
  • frequency information available
  • input-analysis possible
  • analysable for different phenomena

5
Problems
  • low comparability
  • lack of data for low-frequency phenomena
    (morphemes, constructions,)
  • underestimation of productivity due to recurrent
    situations which require similar linguistic
    encoding

6
Production Experiments
  • Nonce-word tests (Berko 1958)
  • This is a wug. These are two
  • Description of scenes which are acted out by the
    researcher

7
Advantages
  • high comparability
  • data for low-frequency phenomena (morphemes,
    constructions,)
  • no underestimation of productivity due to
    recurrent situations which require similar
    linguistic encoding

8
Problems
  • age-dependent (usually at least 3 years)
  • underestimation of productivity due to
    comparatively high task-demands
  • no frequency information available
  • no input-analysis possible
  • analysis restricted to target phenomenon

9
Elicitation Games
  • creation of contexts for constructions,
    morphemes, etc. in a game-like setting
  • e.g. eliciting complete sentences with the verb
    to give in an "animal feeding game" participants
    have to feed toy animals and explain which food
    items they would like to give to which animals
    (Eisenbeiss 1994)
  • mostly used with children that are too young for
    experiments or as supplements to
    (quasi-)naturalistic data or experiments

10
Advantages
  • usable with two-year olds
  • high comparability
  • data for low-frequency phenomena (morphemes,
    constructions,)
  • no underestimation of productivity due to
    recurrent situations which require similar
    linguistic encoding
  • no underestimation of productivity due to high
    task demands
  • analysable for different phenomena

11
Problems
  • age-dependent (usually at least 16 years)
  • no frequency information available
  • no input-analysis possible

12
Types of Elicitation Tasks and Stimuli
  • Interactional Setting
  • Target Type
  • Stimulus Format

13
Interactional Setting
  • Director/matcherA director describes a
    scene/object etc. and a matcher who is not able
    to see this scene/object, has to recreate
    it.E.g. The matcher has to build a toy house
    identical to the one created by the director who
    is hidden behind a screen.
  • Speaker/Listener A speaker provides information
    for someone who does not have access to this
    information. E.g. The speaker retells a story
    (s)he heard/read while the listener was not in
    the room.
  • Co-PlayersAll participants are involved in a
    game and provide each other with information to
    co-ordinate their actions. E.g. The players are
    involved in a construction or puzzle game where
    not everyone has access to all pieces.

14
Target Type
  • the use of a particular form or construction
  • the linguistic encoding of a particular function
    or meaning (which can be encoded in different
    ways)

15
Stimulus Format
  • pictures
  • photos
  • computer animations
  • videos
  • toys
  • real objects

16
Pictures
  • better for descriptions of static
    objects/properties than for event descriptions
    and verb elicitation
  • requires knowledge of artistic conventions (e.g.
    lines for movement, shading etc.)
  • can be used for unrealistic events (e.g.
    animals in different colours or positions)
  • comparatively easy to create with clip art and
    standard software
  • comparatively easy to modify for minimal
    variations (e.g. colour)

17
Photos
  • better for descriptions of static
    objects/properties than for event descriptions
    and verb elicitation
  • do not require knowledge of artistic conventions
    and are comparatively natural
  • problematic for unrealistic events (e.g.
    animals in different colours or positions)
  • comparatively easy to create and manipulate with
    standard photo equipment and Photoshop or similar
    software
  • cannot be as easily modified for minimal
    variations (e.g. colour) as pictures, but
    possible in principle

18
Computer Animations
  • better for descriptions of dynamic events and
    verb elicitation than for descriptions of static
    objects/properties
  • not very naturalistic, in particular when it
    comes to natural movements of people and animals
  • can be used for unrealistic events (e.g. funny
    movements of animals)
  • difficult and time-consuming to create
  • good control for minimal variations (e.g.
    direction or manner of motion)

19
Videos
  • better for descriptions of dynamic events and
    verb elicitation than for descriptions of static
    objects/properties
  • comparatively natural
  • cannot easily be used for unrealistic events
  • comparatively simple to create with standard
    digital video equipment and editing software
    (Adobe etc.)
  • cannot be as easily modified for minimal
    variations as computer animations (e.g. direction
    or manner of motion) because actors tend to
    introduce unwanted modifications

20
Toys
  • e.g. stuffed animals, cars, blocks
  • appropriate for descriptions of dynamic events
    and verb elicitation as well as for descriptions
    of static objects/properties
  • not completely naturalistic, in particular when
    it comes to natural movements of people and
    animals
  • often very culture-dependent
  • can be used for unrealistic events (e.g. funny
    movements of animals)
  • usually easily obtainable
  • object properties can be fairly well controlled,
    but for dynamic events, actions of toy actors
    tend to introduce unwanted modifications

21
Real Objects
  • e.g. tools, household items like pots, dishes
  • appropriate for descriptions of dynamic events
    and verb elicitation as well as for descriptions
    of static objects/properties
  • very naturalistic
  • basic objects are often less culture-dependent
    than toys
  • can be used for realistic and unrealistic
    events (e.g. funny movements of pots)
  • usually easily obtainable
  • object properties are a bit harder to control
    than for toys and modifications might reduce
    naturalness (e.g. atypical colours for household
    items)
  • for dynamic events, manipulations of the objects
    tend to introduce unwanted modifications

Construction-specific Elicitation Games for
German NPs (Eisenbeiss 1994, 2002)
(Clahsen 1982, Wagner 1985, Clahsen et al. 1990)

24
Problems for Naturalistic Corpus Studies on NPs
  • Some NP types are comparatively frequent and
    become more frequent with increasing utterance
    length (MLU).
  • BUT Some NP types (e.g. those with contexts for
    adjectivearticle or possessive s)
  • are rare
  • occur in some files, but not in others
  • do not become more frequent over time (though
    childrens utterances get longer)

25
NPs with NOM/ACC/DAT-Articles
  • For instance
  • clown game putting clothes on a clownWhat is
    this ? This is ... (NOM).What does the clown put
    on now? He puts on ... (ACC)
  • feeding game Which food (ACC) do you give to
    which animal (DAT) ?

26
NPs with NOM/ACC/DAT-Articles
27
NPs with AdjectiveArticle
  • For instance
  • picture-matching game putting picture cards on
    a board with pictures (red balloon, blue
    ballon,...)
  • What is this ? This is ... (NOM).What goes onto
    this picture here? (NOM)What do you want to put
    here (ACC)

Preliminary Summary
  • Elicitation Games are effective tools for
  • the collection of corpora that
  • provide data for quantitative analyses of
    low-frequency phenomena
  • can be analysed with respect to other phenomena
    as well

32
BUT
  • We have to
  • enhance the effectiveness and naturalness of
    elicitation games
  • create more flexible games that can be adapted to
    a variety of constructions in a variety of
    languages

33
Desired Task Properties
  • a natural communicative situation in which the
    speaker provides relevant information for the
    researcher or a third party
  • motivating speakers to continue (e.g. by
    involving an inherent endpoint)
  • appropriate for different cultures and ages
  • easily transportable and low sound emission
  • usable for
  • Ns or Vs
  • NPs or sentences
  • variable but comparable for longitudinal work

34
The Puzzle Task
  • a task with co-players child describes
    contrasting pictures on a puzzle board, adult
    finds the matching pieces, child puts them into
    the correct cut-out
  • exchangable pictures and puzzle pieces
  • can be used to elictit particular forms or to
    elicit the linguistic encoding of particular
    meanings

35
Studies of Argument Structure and Argument Marking
  • Constructions with more than 2 arguments(e.g.
    dative constructions)
  • Optional arguments (e.g. subject drop in
    Japanese)
  • Optional grammatical markers (e.g. optional case
    markers in Japanese)
  • extra arguments(e.g. external possession in
    German)

36
External Possession in German
  • The Possessor can be realized as
  • a dative argument of the verb (preferred)
  • Ich habe dem Bären die Pfote gewaschen.I have
    the bear DAT the paw ACC washed.
  • a genitive NP in the POSSESSUM-NP
  • Ich habe die Pfote des Bären gewaschen.I have
    the paw the bear GEN ACC washed.
  • a PP in the POSSESSUM-NP
  • Ich habe die Pfote von dem Bären gewaschen.'I
    washed the paw of the bear PP ACC.'

37
Internal Possession in Japanese
  • Dative External Possession Constructions are not
    available
  • POSSESSORS are realized as a genitive NP in the
    POSSESSUM-NP
  • Watashi-wa kuma-no asi-o aratta.I have the
    bearGEN the paw ACC washed.

38
Data
  • German 39 recordings(picture descriptions and
    asking for pieces)1286 utterances with/without V
    21 children (37-66)
  • Japanese67 recordings (asking for pieces) 421
    utterances with V 16 children (211-65)

Error Types
  • More contexts for errors but no qualitative
    differences in error types observed so far
  • PPs instead of IOs
  • naturalistic (Carsten 36) für'n papa sollste
    aber den schenken for the daddy shall PART
    this-one give
  • elicited (Jannik 64)
  • da gibt das baby fuer das schaf ehm den
    gras. there gives the baby for the sheep ehm
    the grass

Conclusion
  • Elicitation games provide a useful tool for
    corpus collection.
  • We should develop more elicitation tasks and
    employ them in cross-cultural and
    cross-linguistic studies.

48
Outlook
  • even more general elicitation games
  • usable with several children
  • coverage of a broad range of phenomena (e.g. N,
    A, V, P, number, case, gender, descriptions of
    movement and location, physical and psychological
    events,)
