2Overview
- 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
3Naturalistic Data
- other term spontaneous speech data
- recording of ongoing communicative events (free
play, dinner table conversation,)
4Advantages
- age-independent
- no special task-demands
- frequency information available
- input-analysis possible
- analysable for different phenomena
5Problems
- low comparability
- lack of data for low-frequency phenomena
(morphemes, constructions,) - underestimation of productivity due to recurrent
situations which require similar linguistic
encoding
6Production Experiments
- Nonce-word tests (Berko 1958)
- This is a wug. These are two
- Description of scenes which are acted out by the
researcher
7Advantages
- high comparability
- data for low-frequency phenomena (morphemes,
constructions,) - no underestimation of productivity due to
recurrent situations which require similar
linguistic encoding
8Problems
- 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
9Elicitation 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
10Advantages
- 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
11Problems
- age-dependent (usually at least 16 years)
- no frequency information available
- no input-analysis possible
12Types of Elicitation Tasks and Stimuli
- Interactional Setting
- Target Type
- Stimulus Format
13Interactional 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.
14Target 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)
15Stimulus Format
- pictures
- photos
- computer animations
- videos
- toys
- real objects
16Pictures
- 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)
17Photos
- 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
18Computer 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)
19Videos
- 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
20Toys
- 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
21Real 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
22Construction-specific Elicitation Games for
German NPs (Eisenbeiss 1994, 2002)
(Clahsen 1982, Wagner 1985, Clahsen et al. 1990)
23NPs in Spontaneous Speech (Eisenbeiss 2002)
24Problems 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)
25NPs 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) ?
26NPs with NOM/ACC/DAT-Articles
27NPs 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)
28NPs with AdjectiveArticle

31Preliminary 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
32BUT
- 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
33Desired 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
34The 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
35Studies 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)
36External 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.'
37Internal 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.
38Data
- 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)

44Error 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

47Conclusion
- 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.
48Outlook
- 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,)
