This
studyinvestigated
comprehensionprocesses
of
Japanese
sentences whichincluded
an adjective-nounphrase,
Specifically,
we examined whether evaluation of a consistent semantic relationbetween
an
adjective
and a nounin
a sentence of readingmaterial
was
suspended
untilthe
argument structure of
the
sentence wasconstructed.
Twenty-three
participants
readtwo
types
of
sentences
:
acceptable
sentencesthat
contained aplausible
adiectjve-nounphrase,
andunaccepta-ble
sentencesthat
contained
an
implausible
adjective-nounphrase.
In
comparison withthe
acceptablesentences,
phrase-by-phrase
readingtime
for
the
unacceptable sentences wasprolonged
not only atthe
position
of adjective-nounphrase
but
also
at
the
position
ofthe
verbthat
construct-ed
the
propositional
representation efthe
sentence.This
result
suggests
that
evaluation
of a semantic relation of anadjective-noun
phrase
is
postponed
until
the
coherent
argument
structureis
constructed.Key

A
Japanese
sentence such as "gghS[]iJilltzztL7t(A
police
othcer was afraid of apuppy)"
often
causes
a
negative reactionby
areacler,
but
a
sentence
such
as
"mefiigggabSjikigMtLk(A
cowardly
police
oMcer
was
afraid
of apuppy)']
does
not.The
difference
in
the
reactionto
these
sentencesdepends
on whether
the
attributive
adjective
"cowardly"modifies
the
noun[`police
oMcer"
in
the
nounphrase
(Murphy,
1990).
According
to
Murphy
(1990),
anadjective
modifies a nounby
altering aschema
in
some
way, andthe
schema canbe
described
as
a
structured
set
of
slots
andfi11ers.
Within
this
frame-work,the
reason
fer
the
awkwardness
evokedby
the
sentence
mentioned
above
canbe
attributedto
the
idea
that
the
schema of apolice
oficer
mayhave
aPERSONALITY
slot withbrave
as
a
default
value.However,
in
the
second example,,the
adjective
`Ccow-ardly"
replaces
the
value ofthe
PERSONALITY
slotwith
cowantly.
The
readerstherefore
evaluate "a'

Hiroshima,

Hiroshima

cowardly

oficer"
as one who couldplausibly
be
afraid ef apuppy,
Consequently
readers
find
the
sentence "acowardly
po]ice
oMcer wasafraid
of
a
puppy"
asbeleivable.
According
to
the
proposal
that
sentencecompre-hension
is
a
process
of construction ofpropositional
representations, readers must
judge
the
plausibility
of concepts of adjective-noun cembinations as either a subject or object ofthe
predicate,
We
therefore
examined
whether evaluation of a consistentseman-tic
relationbetween
an adjective anda
noun
in
a
sentence
was suspended untilthe
argument structureof
the
sentencewas
constructed.
To
examinethis
possibility
wecompared
the
comprehensien oftwo
types
ef
sentences
that
had
the
same syntacticstruc-ture
but
with adifferent
semantic
relation
in
the
'
adjective-noun
phrase.

sentence wasacceptable
'
and
included
aplausible
adjective-noun
phrase
: "veLv)gghSfilMbe'ti-"

Methods
M'aterial
The
reading material wasJapanese
sen・tences
consisting of an adjective-nounphrase,
a
bare
noun
phrase,
and a verb.The
adjective-nounphrase
was eitherthe
subject orthe
object ofthe
sentence.A
verb
is
usually
placed
at
the
final
pesition
in
Japanese
sentences.
The
word order was"`subject-object-predicator(verb)".
'In
the
present
experimentcom-plex
sentences were used sothat
the
readingprocess
at
the
position
of verb couldbe
determined,
'
A
com-plex
sentence consists of acomplementsentence
(that
is,
a
sentence
of
readingmaterial)
followed
by
amainsentence.
For
example,
the
reading
material
sentence
"eeLL)grrbgfi
thigS'
5"
was
followed
by
the
mainsentence "tkmaSAvhSeeV]k".
Two
lists
ofthe
experimental material were created.

Procedure
In
every
trial,
a
sentence
was

phrase

A

results
indicated
that

the

readingtime
ofthe
unacceptable
sentences
wasprolonged
not only atthe

but
also atthe

This
result
supported
the
prediction
that
the
evaluation
of
a
consistent
semantic
relation
in
anadjective-noun
phrase
wassuspended
untilthe
argu-ment structure of
the
sentence was constructed.The
findings
suggestthat
readersdepend
on agrammati-cal category of words and on
the
syntacticinforma-tion
of
a
sentence
to
combine
the
arguments
withthe
predicate.
In
addition
readers
use
the
meaning
of
words and
their
knowledge
ofthe
worldto
construct coherent argument structures.
