On-line experimental techniques tap into
automatic unconscious processes involved
in language comprehension and production
and minimize participants‘ reliance on
explicit or metalinguistic knowledge.
Presentation by: Vicky Chondrogianni & Theo Marinis
“There are two basic types of time-sensitive
measures available to examine language
processing: behavioral measures (e.g.
comprehension response times and
production latencies) and physiological
measures (e.g. event-related brain
potentials (ERPs) and eye-movements).”
(Clahsen 2008, p. 3)
Behavioral methods
Eye tracking
 Priming experiments measuring reaction
time (children are usually slower than
adults)
 Cross modal priming
 Monitoring task (self paced
reading/listening) (Taxler 2005 from
Clahsen 2008)

Eye tracking


Linguistic abilities are assessed by tracking and
recording eye movements in response to predetermined
verbal and visual stimuli
Eye-tracking in language processing studies allows
researchers to track and record participants' eye
movements when they:



Read a sentence
Look at the pictures on the computer screen as they listen to
sentences that describe these pictures
Experimental eye tracking data is obtained to investigate:
understanding of spoken language
 cognitive processes related to spoken language
 ability to process and interpret metaphor and figurative language
 body language and lip reading
 turn taking in conversations
 audio-visual integration
 reading behavior
 tracking-task performance
 scene exploration strategies
(http://www.tobii.com/eye-tracking-research/global/research/linguistics/)

Preferential looking, Head-turn
method
Children (and adults) tend to look at
pictures corresponding to a sentence they
hear. This can be used to test word
comprehension as well as sentence
comprehension

“A regression is any eye movement
that begins at the right-most point
the reader has fixated and leaves
the currently fixated region to the
left. This definition is therefore only
concerned with disruption occurring
during initial processing. First-pass
time is the sum of the fixations
occurring within a region before the
first fixation outside the region. If the
eye fixates a point beyond the end of
a region before fixating the region for
the first time, then the first-pass time
for that region is zero. (This measure
is equivalent to the gaze-duration
measure [e.g., Rayner & Duffy,
1986], when the region is a single
word.) Total time is the sum of all
fixaions in a region.”
(Pickering & Traxler, 1998)

“The regressions and total-time data demonstrate that:





readers misanalysed both types of ambiguous sentence
sentences with implausible object analyses were harder to
process during the critical noun phrase
sentences with plausible object analyses were harder to process
during the syntactically disambiguating verb phrase.
The regressions data demonstrate further that readers
incrementally interpreted the sentences, because
plausibility effects emerged before the point of syntactic
disambiguation.
Readers must have initially treated the magazine about
fishing as the object of the subordinate verb (with
magazine as the head noun).”

2010. On-line Processing of Articles and
Clitic Pronouns by Greek Children with SLI.
In Franich, K., Iserman, K, & Keil, L. (Eds.).
Proceedings of the 34th Annual Boston
University onference on Language
Development, Volume 1, 78-89.
The study examines whether Greek
children with SLI and a group of agematched typically-developing (TD) children
are sensitive to the omission of articles
and clitic pronouns when they listen to
sentences in real-time.
 Following Tsimpli & Stavrakaki’s (1999)
Interpretability Hypothesis a difference is
expected between indefinite article vs.
clitic pronouns and definite article

20 with TLD (Mean age 7;0) & 13 with SLI
(mean age 6;9)
 SPL with E-prime
 The grammatical version was recorded
and the clitic/article was spliced out to
generate the ungrammatical ones

(5) Definite article – subject position
‘Yesterday a dolphin was playing in the sea with the other
animals. Late / in the afternoon / (the) dolphin / chased / the fish.’
(6) Definite article – object position
‘Yesterday a kangaroo was playing with a green ball. The
kangaroo / kicked / (the) ball / on the pitch / yesterday
afternoon.’
(7) Indefinite article – object position
‘Yesterday a naughty fox chased some other animal. The fox /
chased / (a) donkey / in the woods / yesterday at midday.’
(8) Accusative direct object clitic pronoun
‘The lion wanted to eat the deer. The deer / got very scared /
when / the lion / (it) bit / in the jungle / on the rocks.’
Definite article in subject position
Both groups showed a main effect of Grammaticality (TD children: F1 (1, 26)
= 58.074, p < .001; F2 (1,7) = 26.375, p = .001; children with SLI: F1 (1, 12)
= 5.626, p < .05; F2 (1,7) = 5.397, p = .053).
Definite article in object position
TD children showed a main effect of Grammaticality in both analyses per
subjects and per items (F1(1,26) = 247.376, p <.001; F2(1,7) = 21.804, p <. 01).
Children with SLI showed a main effect of Grammaticality only in the analysis
per participants (F1 (1,12) = 6.423, p <.05; F2 (1,7) = 2.292, p >.1).
Indefinite article in object position
Both groups showed a main effect of Grammaticality (TD group: F1
(1,26) = 105.969, p <.001; F2 (1,7) = 47.920, p<.001; SLI group: F1
(1,12) = 62.471, p<.001; F2(1,7) = 81.401, p<.001).
Clitic pronoun condition
TD children showed a significant main effect of Grammaticality (F1 (1,26) =
12.189, p <.01; F2 (1,9) = 8.627, p <.01). In contrast, children with SLI showed
no main effect of Grammaticality for either the participant or item the analysis
(F1 (1,12) = 1.402, p > .1; F2 (1,9) = 1.243, p > .1).
Four major findings

2.
3.
Children with TLD are sensitive to
grammaticality
Children with SLI are sensitive to omission of
indefinite article but not to clitic omission as
predicted by the Interpretability Hypothesis as
well as the Surface Hypothesis
Children with SLI are sensitive to definite
article omission which is not predicted – why?
