      <abstract>
        <p>Most studies of implicatures focused on conversational implicatures. This study, however, examined the conventional implicature induced by but. According to the literature, one can assume that the second argument in a 'p but q' construction is the argument with the most weight. This is, however, never experimentally tested with a direct distancingcontrastive but. We presented participants with stories which ended with a direct distancing but construction, in which one of the arguments expressed a feeling of understanding towards the behavior of the main character in the story. The results indicated that indeed the q-argument has most weight. There was, however, also an effect of the specific content of the stories. These results are discussed in light of the hypotheses generated on the basis of previous research with an indirect distancing-contrastive but, but also in the light of the effect of content of the stories in conventional implicatures research and specific task characteristics.</p>

      <title>Introduction</title>
      <p>
        As
        <xref ref-type="bibr" rid="ref2">Clark and Schober (1992)</xref>
        formulated: “It is a common
misperception that language use has primarily to do with
words and what they mean. It does not. It has primarily to
do with people and what they mean. It is essentially about
speakers' intention”. What we want to convey in daily
communication is to a large extent not explicitly expressed.
Instead, people in conversation make use of facial
expressions, gesticulation, and the (assumed) intentions of
the speaker to make their interactions successful.
        <xref ref-type="bibr" rid="ref6">Grice
(1989)</xref>
        is one of the founding fathers of pragmatics and
provided us with a theoretical framework to discuss this
issue. Starting point was the general principle of
cooperation, which
        <xref ref-type="bibr" rid="ref6">Grice (1989)</xref>
        formulates as follows:
“Make your conversational contribution such as is required,
at the stage at which it occurs, by the accepted purpose or
direction of the talk exchange in which you are engaged.”
The cooperative principle can be divided into four maxims:
the Maxim of Quantity, the Maxim of Quality, the Maxim
of Relation and the Maxim of Manner. These maxims
respectively imply that interlocutors are always expected to
offer contributions which are informative, truthful, relevant
to the goals of the conversation and appropriately phrased.
According to
        <xref ref-type="bibr" rid="ref6">Grice (1989)</xref>
        , whenever people follow these
maxims, the result is an efficient exchange of information.
However, these maxims are not exhaustive. Other maxims,
such as maxims of social or ethical nature, are necessary in
communication as well.
      </p>
      <p>
        By means of the cooperative principle and the maxims,
        <xref ref-type="bibr" rid="ref6">Grice (1989)</xref>
        describes the inference process, the retrieval of
a speaker’s meaning. This brings us to the term
‘implicature’. In his work, he made a difference between
two categories of implicatures, i.e. conversational
implicatures on the one hand and conventional implicatures
on the other hand. The idea of implicatures became quickly
popular both in theoretical and experimental pragmatics.
However, experimental research on implicatures has almost
completely concentrated on (generalized) conversational
implicatures. One has to be even more precise: most
experimental research focused on the subcategory of scalar
implicatures
        <xref ref-type="bibr" rid="ref14 ref15 ref3 ref4 ref5">(e.g., De Neys &amp; Schaeken, 2007; Dieussaert,
Verkerk, Gillard, &amp; Schaeken, 2011; Doran, et al., 2009;
Noveck, 2001; Papafragou &amp; Musolino, 2003)</xref>
        .
        <xref ref-type="bibr" rid="ref8">Horn (1972)</xref>
        developed this concept. Horn-scales involve a set of
alternative expressions of the same grammatical category,
but with a difference in semantic informativeness.
Underlying these scales is the assumption that the use of a
semantically weaker term implies that the stronger one does
not hold. We would do this, because we want to be as
informative as required, but also not more informative as
required. This is called by
        <xref ref-type="bibr" rid="ref6">Grice (1989)</xref>
        the maxim of
quantity. The most well-known examples of such scales,
ordered from strong to weak are “all, most, some” and “and,
or”.
      </p>
      <p>The scalar implicatures are examples of generalized
conversational implicatures, which are assumed to occur
very systematically although the context may be such that
they do not occur. In contrast, there are also particularized
conversational implicatures, which were assumed to be less
systematic and always clearly context dependent. An
example of such a particularized implicature is the situation
where one wonders were the hamburger is and the
grandmother suddenly says: “Well, the dog is looking very
happy.” In such a situation, we will derive the implicature
that the grandmother thinks that the dog ate the hamburger.
The derivation from “looking happy”’ to “did eat the
hamburger” can only be made in this very specific context.</p>
      <p>
        In the current study we will not focus on conversational
implicatures, but on the seldom investigated conventional
implicature. Conventional implicatures are independent of
the cooperative principle: A statement always carries its
conventional implicature, but this implicature is not part of
the semantic meaning of the terms. Based on the different
definitions found in the literature,
        <xref ref-type="bibr" rid="ref9">Horn (2004)</xref>
        came up
with a summarizing definition of this concept:
“Unlike an entailment or logical presupposition,
this type of inference is irrelevant to the truth
conditions of the proposition. This inference is not
cancellable without contradiction, but it is
detachable, in the sense that the same
truthconditional content is expressible in a way that
removes (detaches) the inference. Such detachable,
but non-cancellable aspects of meaning that are
neither part of, nor calculable from ‘what is said’,
are conventional implicatures.”
        <xref ref-type="bibr" rid="ref9">(Horn, 2004)</xref>
        <xref ref-type="bibr" rid="ref10">Huang (2006)</xref>
        defines a conventional implicature as “a
nontruth-conditional inference which is not deductive in any
general, natural way from the saying of what is said, but
arises solely because of the conventional features attached
to particular lexical items and/or linguistic constructions”
        <xref ref-type="bibr" rid="ref10">(Huang, 2006)</xref>
        .
      </p>
      <p>
        More specifically, we investigated in the present study the
implicature induced by the conjunction ‘but’. The word but
(translated from Dutch maar) is the most commonly used
connector to express a contrastive-concessive relation
        <xref ref-type="bibr" rid="ref17">(Van
Belle &amp; Devroy, 1992)</xref>
        . This ‘p but q’ relation is a particular
type of contrast in which one part of the utterance (p) is a
concession and the other, contrastive part of the utterance
(q) denies the inference that could be made based on p
        <xref ref-type="bibr" rid="ref16">(Van
Belle, 2003)</xref>
        . In the Algemene Nederlandse Spraakkunst
(ANS; General Dutch Grammar), three types of the
connector but are distinguished
        <xref ref-type="bibr" rid="ref7">(Haeseryn et al., 1997)</xref>
        .
      </p>
      <p>First, but can be used in a dividing contrast, in which but
can be replaced by and. Replacing and with but emphasizes
the contrastive nature of the connection, but not the other
way around (e.g., he is rich but he is friendly).</p>
      <p>Second, but can be used in a replacing contrast. In such a
construction, the first part of the sentence is a negation and
the second part replaces the first part by expressing what’s
true (e.g., not bananas but apples are my favorite fruit).</p>
      <p>
        Finally, in a distancing contrast, but connects two parts of
a complex speech act and the second part is disassociated
from the first part, without denying what is being expressed
in the first part
        <xref ref-type="bibr" rid="ref17">(Van Belle &amp; Devroy, 1992)</xref>
        . In this type of
‘p but q’ construction, the speaker endorses or recognizes
that p is true
        <xref ref-type="bibr" rid="ref16">(Van Belle, 2003)</xref>
        . However, by using the word
but, the possible inference derived from p is cancelled.
There are two possible ways in which this cancellation can
be manifested
        <xref ref-type="bibr" rid="ref13">(Moeschler &amp; de Spengler, 1982)</xref>
        .
      </p>
      <p>On the one hand, q can directly cancel the inference from
p because it contains a conclusion that contradicts the
inference from p (p (p → r), but q (q = not-r) (so not-r)).
For example: “The water is cold (→ will not swim), but I
swim in it”. The connector but, used in a direct distancing
contrast, is labelled as a ‘concluding but’. In a direct
concession, p and q are always connected by their content: p
expresses a cause or a good reason for r and ‘but q’
expresses the conclusion. It’s because of this connection that
but can be replaced or strengthened by a conjunctional
adverb such as nevertheless (e.g., the water is cold,
nevertheless I swim in it).</p>
      <p>
        On the other hand, q can indirectly cancel the inference
from p because q contains an argument that can be
considered as stronger or more relevant than p. (p (p → r),
but q (q → not-r) (so not-r)). E.g.: “The water is cold (→
will not swim), but I like swimming (→ will swim). (So I
will swim)”. Note that it is the conventional meaning of but
that causes the argument from q to overrule the argument
from p. When the two arguments trade places, the opposite
conclusion follows because the q-argument always
outweighs the p-argument. E.g.: “I like swimming, but the
water is cold. So I will not swim.” The connector but, used
in an indirect distancing contrast, is labelled as an
‘argumentative but’. This is in line with the three claims
        <xref ref-type="bibr" rid="ref1">Anscombre and Ducrot (1977)</xref>
        postulated concerning this
type of ‘p but q’ utterance:
1. q is always the argument with most weight and the
‘p but q’ construction must be viewed as a defense
of not-r.
2. By uttering ‘p but q’, the speaker always expresses
some kind of acceptance of p.
3. ‘p but q’ constructions are always aimed at
cancelling a particular conclusion r.
      </p>
      <p>The word so, following a ‘p argumentative but q’ utterance,
introduces the expected conclusion from q (e.g., “The water
is cold, but I like swimming. So I will swim.”). In contrast,
the word nevertheless following a ‘p argumentative but q’
utterance is used as a conjunctive adverb and has the
purpose of reversing the argumentative orientation again
and thus directing the reader towards the conclusion
stemming from p (e.g., “The water is cold, but I like
swimming. Nevertheless, I will not swim.”).</p>
      <p>
        Given the high frequency of the connector but, it is
surprising that there is almost no empirical research about
this connector. One of the exceptions is
        <xref ref-type="bibr" rid="ref11">Janssens and
Schaeken (2013)</xref>
        . They investigated the indirect distancing
contrast use of but. In their research, they presented adult
participants with short stories. Each of these stories ended
with a ‘p but q’ sentence, which was followed by two
possible conclusions. The participants were instructed to
indicate the appropriate conclusion. These were either two
so-conclusions (‘so conclusion from p’ and ‘so conclusion
from q’) or two nevertheless-conclusions (‘nevertheless
conclusion from p’ and ‘nevertheless conclusion from q’).
The appropriate pragmatic conclusion following so is the
conclusion inferred from q and the appropriate conclusion
following nevertheless is the conclusion from p
        <xref ref-type="bibr" rid="ref16">(see Van
Belle, 2003)</xref>
        . The experiments showed that adults indeed
understand the pragmatic meaning of but: so-conclusions
primarily followed the q-argument and the
neverthelessarguments followed the p-argument, although the preference
was smaller. A plausible reason for the latter effect is the
difficulty of nevertheless: one has to negate the negation of
the expectation based on the p-argument
      </p>
      <p>
        Interestingly, the content of the arguments also had an
effect. In the experiment,
        <xref ref-type="bibr" rid="ref11">Janssens and Schaeken (2013)</xref>
        presented not only sensible arguments, but also irrelevant
arguments. In the swimming example above, both
arguments are sensible in a context in which a person is
doubting whether or not he will jump in the water. In this
same context, uttering “I like swimming, but I have a
brother” clearly contains an irrelevant q-argument. These
irrelevant arguments were included to examine whether the
pragmatic meaning of but is understood or used irrespective
of the content of the arguments. This was not the case. It
was observed that in those cases where an irrelevant
argument was combined with a sensible argument, the
participants had a clear preference for the conclusion from
the sensible argument. This was true for both the
soconclusions and the nevertheless-conclusions.
      </p>
      <p>
        In a second experiment,
        <xref ref-type="bibr" rid="ref11">Janssens and Schaeken (2013)</xref>
        asked participants to justify their answers. It was observed
that participants mostly referred to the content of the
arguments whenever they did not provide the appropriate
conclusion.
      </p>
      <p>
        The present research builds on the work of
        <xref ref-type="bibr" rid="ref11">Janssens and
Schaeken (2013)</xref>
        , but there were innovations.
      </p>
      <p>First, instead of investigating the indirect distancing
contrast use of but, in the current experiment the direct
distancing contrast use of but will be examined.</p>
      <p>Second, one argument of the ‘p but q’ construction
represents a relevant argument in daily life and might even
have repercussions for consoling talks, that is, expressing
that you understand the action of the person. An example of
such a sentence is:</p>
      <sec id="sec-1-1">
        <title>I understand that after many attempts you lost the hope for reconciliation, but a good communication between the two of you is important for the entire company.</title>
        <p>In half of the problems, the “I understand”-argument was
the p-argument, for the other half of the problems, it was the
q-argument. To control for the real effect of but, half of the
problems contained the connector but, and for the other half
of the problems, the two arguments were separated with a
‘period’:
between the two of you is important for the entire
company.</p>
        <p>Third, the dependent variable was a different one than in
previous research. Instead of evaluating conclusions,
participants were asked to express on a scale whether or not
they expected that the person in the story would feel
understood or not.</p>
        <p>Our hypothesis was that there would be a significant
interaction between order (whether p or q is the
‘understanding argument’) and connector (but or period).
We expected the effect or order to be only there when the
connector but is used instead of the period. Only in that case
the q-argument has more weight, leading to higher feelings
of being understood when the q-argument is the
‘understanding argument’.</p>

      <title>Experiment</title>

    <sec id="sec-3">
      <title>Method</title>
      <p>Participants A total of 192 adults participated in the
experiment. They were all psychology students at the
University of Leuven and participated as part of a course
requirement.</p>
      <p>Design The experiment had a 2x2x2 design, whereby all
independent variables were manipulated between
participants. First, the connector was either but or a period.
Second, the proposition in which the feeling of
understanding was expressed was either the p-argument or
the q-argument. Third, to control for possible content
effects, we developed two different stories (one about a
company, one about an exam). The dependent variable was
a rating of the feeling of being understood of the main
character.</p>
      <p>Material and Procedure Each of the stories started with a
description of a very difficult situation. The company-story
(story A) goes as follows:</p>
      <p>Joke had a violent fight with her colleague. The
close collaboration between them is important for a
good functioning of the business. A
misunderstanding that arose a few days ago, has
escalated. Joke is convinced that her colleague
made a mistake and does not want to concede. Her
colleague is blaming Joke. Joke has repeatedly
tried to talk about this, but this never led to a
success. As a consequence, being in the same room
leads inevitably to an angry passage of words.
Therefore, Joke decided to not say a word to her
colleague. Joke is very determined to keep silent
for the rest of their working collaboration.</p>
      <sec id="sec-3-1">
        <title>I understand that after many attempts you lost the hope for reconciliation. A good communication</title>
        <p>After this introduction, the story continues with the
introduction of the crucial manipulation:
She talks about the situation with a different
colleague. The colleague tells her: “I understand
that after many attempts you lost the hope for
reconciliation, but a good communication between
the two of you is important for the entire company.
A quarter of the participants in the company-condition
received this story; for another quarter, the order of the two
arguments was reversed; another quarter received the
arguments in the same order, but instead of using the
connector but, the sentences were now simply separated by
a period; finally, another quarter received the two arguments
in the opposite order, separated by a period. The
universitystory (Story B) had the same four versions. An example of
the crucial sentence in the university story is:</p>
      </sec>
      <sec id="sec-3-2">
        <title>Carrying on with your study is important for your chances for a job later on, but I understand that you want to stop the study after such a dishonest act.</title>
        <p>Each participant received only one story. The participants
were tested in five different groups, in which the different
versions were distributed randomly.</p>
        <p>The participants were asked to imagine how the main
character in the story would feel after the last sentence.
They had to indicate this on a seven-point scale, going from
“feels totally misunderstood” to “feels totally understood”.</p>
      </sec>
    </sec>
    <sec id="sec-4">
      <title>Results and Discussion</title>
      <p>First, we observed an effect of order, that is, when the
expression of understanding is the q-argument, the feeling
of being understood is higher than when it is the p-argument
(4.01 vs. 3.16; F (1,188) = 19.37, p &lt; .05, partiële η² = .09).</p>
      <p>Second, there was, as expected, no significant main effect
of the type of connector (but: 3.51; period: 3.66; F (1,188) =
0.48, p &gt; .05, partiële η² = .001). However, there is a
significant interaction between order and connector (F
(1,188) = 8.66, p &lt; .05, partiële η² = .04). The effect of
order is only there when the connector but is used instead of
the period.</p>
      <p>Third, to complicate things a little bit, there is a
significant main effect of the variable story (story A vs story</p>
      <p>B: 3.95 vs 3.25; F (1,188) = 13.59, p &lt; .05, partiële η² =
.07) and an interaction between the variables story and order
(F (1,188) = 7.25, p &lt; .05, partiële η² = .04) indicating that
the expected effect of order was only there in Story A (4.17
vs 3.25). For Story B, the effect was in the expected
direction, but not significant (3.40 vs 3.08).</p>
    </sec>
    <sec id="sec-5">
      <title>General Discussion</title>
      <p>
        The present study contributes to the very recent
experimental research into the area of conventional
implicatures, and more precisely in the understanding of
but. From these results of the present experiment, we can
conclude that with a direct distancing contrast use of but, the
q-argument indeed has a greater weight than the
pargument: Ratings of the expected feeling of being
understood by the main character were clearly higher when
the expression of understanding was in the q-argument
instead of the p-argument. Importantly, this finding was
only true when the two arguments were connected with but;
when a period was used to connect the two arguments, there
was no significant difference. The greater weight of the
qargument seems even higher than in the experiments of
        <xref ref-type="bibr" rid="ref11">Janssens and Schaeken (2013)</xref>
        in which stories with an
indirect distancing contrast use of but were presented. This
might indicate that the claims of Anscrombre and Ducrot
(1977) and Van Belle (2003) about the indirect distancing
contrast use of but are not only also true for the direct
distancing contrast use, but even in a stronger way.
However, we have to be careful with this conclusion
because of two important problems or shortcomings of the
current study.
      </p>
      <p>
        First, there is the effect of content which was present in
the current experiment. The expected effect was only
significant in story A, the company story. In story B, the
exam story, the trend was in the same direction, but the
effect was not significant. Such an effect of content is not
very surprising.
        <xref ref-type="bibr" rid="ref11">Janssens and Schaeken (2013)</xref>
        also
observed a strong content effect on the understanding of but.
Therefore, one could argue that the observed effect was not
due to the direct distancing contrast use of but, but to the
effect of content. The fact that for Story B the effect was,
although non-significant, in the same direction as for Story
A, strengthens our belief in the observed significant effect.
Nevertheless, we admit that further research is definitely
much needed. Perhaps it is worth mentioning that the
absence of a significant effect of Story B might have
something to do with the fact that the exam story is very
close to home for the participants of this experiment who
were all students themselves. It’s plausible that they
therefore empathize more closely with the main character in
this story and generally judge this character as feeling
misunderstood because of the dishonest situation that is
easily imaginable to them. In future research, including a
greater variety of different context stories should confirm
whether the results of this study can be replicated or are due
to these specific stories.
      </p>
      <p>
        Second, there is the task we used.
        <xref ref-type="bibr" rid="ref11">Janssens and Schaeken
(2013)</xref>
        asked to evaluate which of the given conclusions was
the most appropriate. In the current experiment, participants
were asked to express on a scale whether or not they
expected that the person in the story would feel understood
or not.
        <xref ref-type="bibr" rid="ref12">Katsos and Bishop (2011)</xref>
        compared two different
tasks in which participants had to evaluate scalar
implicatures. In one experiment, they instructed their
participants to judge on a binary scale (right vs wrong) how
well a fictional character described certain situations. They
observed what is typically observed in such binary judgment
tasks when an underinformative sentence was presented,
that is, a sentence in which some is used while all is also the
case (e.g., using the sentence “The crocodile played with
some of the cars” while it was shown that the crocodile
played with all the cars): Children do not penalize such a
description as false whereas adults do. In a second
experiment, they used a three-point scale with different
sized strawberries. Now participants were instructed to
reward a bad conclusion with the smallest strawberry, a
conclusion that was not completely bad nor good with the
medium-sized strawberry, and a good conclusion with the
biggest strawberry. As a result, children’s performance did
not differ anymore from adults’: The underinformative
sentences were judged by both groups with the middle value
on the scale. This indicated that the use of the scale can
reveal children’s comprehension of scalar implicatures
whereas a binary task conceals their competence. Although
we did not use a ternary scale, it is clear that it has more
resemblances with a ternary scale than with a binary scale.
Therefore, one could argue that it is the type of task that
caused the effect and not specifically the direct distancing
contrastive use of but. Further research has to confirm if it
was the type of answer-scale that is a crucial factor.
      </p>
      <p>Furthermore, in our task participants did not have to
evaluate whether or not an utterance was right or wrong (or
something in between), but they had to imagine how the
main character in the story would feel after the last sentence
and express it on a seven-point scale, going from “feels
totally misunderstood” to “feels totally understood”. Again,
further research must clarify whether or not this dependent
variable was crucial in finding the straightforward effects of
but.</p>
