     The Effect of Emoticon in Simplex and Complex Task-Oriented
                           Communication:
                An Empirical study of Instant Messaging

                                   ABSTRACT
Many studies have shed the light on the understanding of general computer-mediated
communication, Instant Messaging (IM), and emotion or emoticons, but little did we
know about specifically the impacts of emoticon in task-oriented IM communications in
workplace. This study addresses the above issue by conducting a three-stage case-study
experiment to (1) categorize the workplace IM messages into coherent groups, (2)
identify the most used emoticons (emblems) for expressing the positive, negative and
neutral emotion in the case company, (3) tested the difference of receiver’s emotional
effect on the received text message with and without emoticons, and (4) the intention to
use emoticons in IM in workplace. Results showed that- (1) negative emoticons could
cause negative effect in both simplex and complex task-oriented communications, (2)
positive emoticons only created positive effect in complex communication and for
female employee in simplex communication, (3) no significant difference found between
task-oriented message with or without neutral emoticon. The intention of using
emoticons in gender difference was not statistically significant but has a higher tendency
on the female employees. Findings and suggestions at the end may illuminate the effect
of emoticon used in IM in workplace.
The Effect of Emoticon in Simplex and Complex Task-Oriented
                           Communication:
                An Empirical study of Instant Messaging

                                INTRODUCTION
   Since the booming of internet and different communication channel, we have been
witnessing an enormous increase in computer-mediated communication (CMC) such as
the asynchronous CMC like email or the synchronous CMC like Instant Messaging (IM).
More and more interactions take place via chatting tool; for example, lots of people use
IM to chat privately as well as professionally. Furthermore, IM services also help us to
maintain our relationships with friends and colleagues in different locations.
   Because CMC has become so common in our daily lives, it raises a big question of
how different online communication is from face-to-face (F2F) communication. For
example, do people chat in IM the same way as in live interactions? Are our
conversations presented in different ways and triggering different emotions or effects in
CMC? Some studies had argued that CMC is a cold and unfriendly medium where
emotions are very difficult to express1, while other studies have declared that the
differences between CMC and F2F are not that big2. Sannomiya and Kawaguchi3
investigated the cognitive characteristics of CMC and F2F communication and
suggested that F2F communication might support the discussion for production of ideas,
while CMC support the discussion for the examination of ideas.
   When discussing the tasked related function of IM, it is interesting to know whether
emotion differs in CMC and F2F? It has been argued that the communication of
emotions is more difficult in CMC than in F2F communication. Burgoon, Buller, and
Woodall4 specifically concluded that nonverbal behavior pre-dominates the effects of
language content in most conditions. What may appear in IM other than pure-text?
Assuming the following scenario: “One day in the morning, when Ted concentrated on
his morning work, suddenly his IM windows prompted an instant message from Monica
“… what do you mean?” Ted was very angry at that time because of Monica’s rude
action; however, he tried to figure out her true meaning and calm down himself first by
returning her a message together with a happy emoticon - ☺. Instantly, Monica returned
a text message together with a happy emoticon, too. This time, Ted had a different
emotion and a better mood compared with previous message.” The above scenario tells
us that the emoticon indeed somehow change the emotion effect between the IM users in
workplace. However, researchers have rarely studied the effect of emoticon of CMC in
workplace, which is a concern since emoticon has been widely used in the workplace
nowadays.
   Emoticons are defined as means to express emotion—hence “emotional icon”—their
actual function hinges on the definition of the word emotion. Emoticons can be
considered a creative and visually salient way to add expression to an otherwise strictly
text-based form. Some studies have also showed that female used more frequent
non-verbal cues in CMC. Therefore, two primary research questions related to emoticons
are presented as follows: First, what are the effects of emoticons on task-oriented
message in IM in workplace? Second, whether there is any gender difference of
emoticon used in IM in workplace?In order to conduct a case-study experiment in this
study, two extra research questions follow: Third, what types of IM messages exist in the
case company? Forth, how do the employees in the case company perceive the use IM in
workplace? The research design will address to answer these four research questions
after the background literature review next.

                             BACKGROUND LITERATE

CMC in Workplace & IM
   Sproull and Kiesler1 argued that e-mail in workplace does not simply speed up the
exchange of information but leads to the exchange of new information as well. In a field
study in a Fortune 500 company, they examined e-mail communication at all levels of
the organization and found that much of the information conveyed through e-mail was
information that would not have been conveyed through another medium.
   IM, another popular CMC tool after email, appears to be progressively used in the
office. To sustain a communication convenient and efficiency advantage, employees use
IM communication to arrange meetings, discuss projects and greet people. For example,
Heavy IM users and frequent IM partners mainly used it to work together to discuss a
broad range of topics via many fast-paced interactions per day each with many short
turns and much threading and multitasking. Light users and occasional pairs generally
used IM to coordinate for scheduling via fewer discussions per day5. In the study of IM
usage in the workplace, Nardi et al.6 concluded that IM is used primarily for four
functions, including (1) quick questions and clarifications, (2) coordination and
scheduling work tasks, (3) coordinating impromptu social meetings, and (4) keeping in
touch with friends and family. Variations of these functions are frequently mentioned in
other researches7-11.
The characteristics or properties of IM includes that (a) IM conversations are brief,
(b) media switching is prevalent, and (c) multitasking is common while conversing in
     6-11            12
IM          . Robb        also argued that IM seems to be steadily advancing into the office
environment whether the financial industry is ready for it or not. IM allows users to chat
online offers real-time access to multiple associates. Wang’s studies13 showed that
colleagues and superiors are the main objects when used inside organization. The
presence of IM will likely increase its acceptance as a business communication tool. In
workplace, one of CMC’s characteristics is task-oriented interactions14. Friendship
development and personalized communication are more important for IM as a
socializing tool and the factors that make IM useful as a socializing tool15. However,
they also argued that IM could be for both social and task-related. The social aspects of
IM are large, indeed, the maintenance of social relationships has been found to be an
essential function of online communication networks. However, unlike F2F social
groups, in which one can passively participate just by being present, online
communication networks somehow require active participation if one is to receive social
benefits16.

Emotion and Emoticon- the visible cue
     Derks et al.17 argued that no indication show that CMC is a less emotional or less
personally involving medium than F2F. On the contrary, they concluded that online and
offline emotional communications were surprisingly similar, and if differences were
found CMC showed more frequent and explicit emotion communication than F2F did.
This is indirectly supported by Kato et al.’s18 conclusion that the affective traits
influenced affective states in e-mail communications in their exploration of the affective
aspect of CMC prior to the comparison between CMC and F2F.
     Kato et. al.19 also showed that a tendency for unpleasant emotions, such as the
negative emoticons of anger and anxiety, to increase when emotional cues transmitted
were low, which has been proven to cause some misunderstandings in e-mail
communication between senders and receivers. Spears and Lea20 also have proposed that
norms and values associated with being online may promote uninhibited behaviors such
as flaming. This idea was tested and showed by Orenga Castellá, Zornoza Abad, Prieto
Alonso, and Peiró Silla21 that negative emotion expression appeared more often in CMC
than in F2F, suggesting that it is the lack of visible cues that may reinforce an experience
of anonymity and explain the results.
     In the same way as non-verbal cues in F2F, emoticons also help to accentuate or
emphasize a tone or meaning during message creation and interpretation22-23.
Furthermore, they help to communicate more clearly a current mood or mental state of
the author24, thereby also providing additional social cues about this person25. Thus,
emoticons serve the function of clarifying textual messages which is similar to
non-verbal displays in F2F17,26. Some studies19,27-28 found that emoticon used in IM was
popular via analyzing the message log or observing the prompting window. Especially,
facial expressions have even greater effects than vocal and spatial nonverbal cues, which
is important in judging positivity because receivers connect the smile with positivity, a
connection that has no analogue in the body and the voice.
   In particular, Huffaker & Calvert’s29 study implies that individuals at least feel the
need to express some of their emotions with short symbols rather than text in weblog and
other chat device-MSN. This is supported by Rivera, Cooke, and Bauhs30 that subjects
who used emoticons were more satisfied with the system than subjects who had no
access to emoticons. Therefore, it is obvious that emoticons have become commonplace
in CMC, and emoticons have obviously found their way into the word list of the
computer-using world.

Gender difference
   About the study of gender difference in CMC, various authors have suggested that
women’s more frequent non-verbal displays, especially smiling, could be reflected in a
more frequent use of emoticons31-32. However, Walther and D'Addario26 argued that
there were no gender differences in the tendency of sending emoticons with e-mail
messages of their own creation, a contrary to the findings of Witmer and Katzman32
(1997) and Wolf33. Savicki and Kelley34 found that women in female-only groups had a
more emotional style because of their repeated and plain self-disclosure. On one hand,
Lee31 studied gender differences in instant messaging and showed that men rarely used
emoticons in conversation with other men, but used more emoticons when interacting
with women. For women, there is no difference in the use of emoticons in relation to
their interaction collaborator: they use the same amount of emoticons in conversing with
men than with other women31. On the other hand, Huffaker and Calvert29 analyzed
emoticons in men’s and women’s blogs, and found that males posted more emoticons
than females did.
   Indeed, Herring35 found that women are ‘‘more likely to appreciate, thank, and
apologize, and to be upset by violations of politeness’’, while men seem less concerned
with graciousness and sometimes violate expected online conduct. However, Wolf 33
demonstrated that women did not use more emoticons, but they did use them in other
ways. She also argued that, in real life, women tend to use emoticons more frequently to
communicate humor of solidarity, whereas men use them to display sarcasm.

Effect of emoticon
   Lo’s study36 concluded that when Internet users face pure text without emoticons,
most people cannot perceive the correct emotion, attitude, and attention intents. On the
contrary, the use of visual cues together with text has been shown to create a more
positive attitude than text alone37. In particular, researchers25,38 found that an emoticon in
combination with verbal “flaming” messages modified the perceived hostility of the
message. However, the effects were not consistent such that the same emoticon
diminished the hostility of a message showing “tension” but increased the perceived
hostility of more hostile wordiness. Unfortunately, Siegel et al.39 discovered that flaming
is found more often in CMC than in F2F setting.
   Derks et al.17 showed that participants used more emoticons in socio-emotional
contexts than in task-oriented contexts. That is, facial displays are affected by social
factors as well as emotions40-41. Some studies found that the motives for using emoticons
are for expressing emotion, enhancing the verbal part of the message (act as a supporting
emoticon), and expressing humor 42. These studies suggest that emoticons are regularly
used and function as emblems for people’s feelings, in a similar way as non-verbal
behaviors in F2F. Emoticons may be used to emphasize or clarify one’s feelings, but
also to soften one’s negative tone and to regulate the interaction, just as smiles and
frowns do in daily life.
   In Walther et al.’s26 experiment of three common emoticons on message
interpretations, the concluded that emoticons' contributions were outweighed by verbal
content, but a negativity effect demonstrated such that any negative message
aspect—verbal or graphic—shifts message interpretation in the direction of the negative
element. However, Derks et al.43 argued that emoticons do influence online message
interpretation and conclude that positive message with a smile is rated more positively
than a positive pure message, and a negative message with a supporting frown is more
negative than a negative pure message. Nevertheless, they also argued that the emoticon
do not have the strength to turn around the valence of the verbal message.

                                 RESEARCH METHODS
Objectives
     Emoticons are graphic representations of facial expressions that many IM users
embed in their messages. These symbols are widely known and commonly recognized
among CMC users, and they are described by most observers as substituting for the
nonverbal cues. According to the above background literature, as one of the most
popular CMC tool, IM has not been investigated independently for its emoticon visible
cue in workplace, the inconsistent interpretation of research outcomes for general
emoticon effects and gender differences in CMC deserves an insightful examination.
Therefore, it is highly important to understand the impacts of emoticons on the
emotional interpretation of the conveyed text message in the organizational context.
   This study sought to explore the effect of emoticons used in IM in an experimental
approach, in which the independent variables contain message-type (simple or complex
task), emoticons (positive, negative, neutral or none) and gender (female or male) while
the dependent variable is the interpretation of receiver’s emotional effect with a focus
limited to the impacts of facial expressions44.

Sample, procedures and measures
    The experimental study was conducted in mid 2008 in a three-stage approach,
which is described as follows:
    First, the actual messages communicated in an organizational context were analyzed
to categorize the messages most likely to appear via the channel of IM. This study
collected 19,885 message logs generated by 199 employees within one month in a
financial institution in Taiwan. Since this institution has launched IM for organizational
communication more than 12 years at the time this study was conducted, the employees
were at least fairly familiar with the applications of IM. Given the huge amount of the
data, only 30% (the first 30% proportion, sorted by content in ascending order) of the
complete set of collected logs (namely 6,000 messages) was analyzed. The text message
of the logs can be categorized into the five groups: (1) discussing or coordinating tasks
(complex communication)- 73%, (2) using emoticons to express emotion- 12%, (3)
arranging or scheduling the meeting or appointment (simplex communication)- 6%, (4)
greeting (simplex communication, for example: saying “hi”)- 5% and (5) linking http
address and miscellaneous- 4%. As shown in the parentheses, groups 1, 3, and 4 are
associated with either complex or simplex types of communication in workplace.
   At the second stage, a survey was conducted to see how emoticons were jointly used
to express emotions in the organizational context. Thirty-two employees in the
aforementioned financial institution participated in this survey and were asked to choose
one appropriate emoticon from the forty-eight emoticons, as shown in Table 1, to
express their positive, negative, and natural emotions, respectively. The emoticons that
received the most popularity were used in the last stage of this research, as experimental
stimuli, to test the impacts of emoticons on receivers’ interpretations of the received
message. Participation was voluntary. No monetary incentives or bonus credits were
provided as inducements to participate.
     At the third stage, a 2 × 4 × 2 experiment was conducted. Specifically, three
independent variables considered in this experiment are the message type of simple and
complex tasks, the emoticon of positive, negative, neutral or none, and gender of female
and male. Because this study was aimed to focus on task-oriented CMC in work place,
emotional effect of emoticon related to social oriented communication such as the
greeting message will not be surveyed at this study. Each of the participants received
instant messages that include both (1) scheduling for a meeting belonging to the simplex
message-type scenario and (2) discussing and asking for a discussion belonging to the
complex message-type scenario toward the topic it addressed. Each text message was
combined with one of the following four emoticon conditions: positive, negative, neutral,
or none as the baseline condition. During the experiment, each participant was required
to answer a questionnaire, which assessed their emotional reactions to the test messages.
Participants were asked to express their feelings measured on a 5-point Liker-type scale
ranging from 1 (very unhappy) to 5 (very happy).
    To ensure the content validity of the survey45, a pre-test was conducted on 5
individuals who had ample experiences in IM use, including two executive MBA
students, two employees of a financial corporation, and one professor in the department
of Information Management. The procedure of the pre-test helped us to modify the
questions and to make sure that respondents understood each question correctly. One
hundred and eighty employees in the aforementioned company were invited to
participate in the experiment. Seventy-six employees, 40 males and 36 females,
voluntarily responded in one month. The factor of gender will also be included in the
analysis of experimental results. Given that the independent variables of gender and type
of emoticon were within-subjects, all participants received both complex and simplex
task-oriented aforementioned, coupled with those four kinds of emoticon conditions.
    In this stage, the intention to use emoticon in IM for employees in work place was
also collected: Prior studies have different arguments about gender difference related to
frequent use or tendency of emoticons in general CMC26,31-32, and some studies even had
showed that females are more intensive user than male. Therefore, one more question
was added to measure employee’s intention, scales from one to five (1: very unlikely, 5:
very likely), to use emoticon in IM.

                          ANALYSES AND ERSULTS
     Table 2 presents the demographic background of study participants: female
participants occupied about 40% and male participants occupied about 60% of all
participants, and about half of the participants’ age ranged from thirty to thirty nine.
The descriptive statistics of the eight experiment conditions are presented in Table 3, for
all, male and female participants. Analyses of variance (ANOVA) was used to test the
difference of emotional effect between text message with and without emoticons by
conducting it to each dependent measure for the effects of message type, emoticons and
gender.
   Table 4 summarized each of the t-test results when compare the difference of text
message with and without emoticons in all, male and female participants. We have the
following four findings. First, the negative emotion increases when negative emoticon
combined with text messages in both the simplex communications and the complex
communication for participants, which echoes Lo’s study35. Second, positive emoticon
increases positive emotion only for complex message type for both genders. Third, for
simplex message type, positive emoticon only increases positive emotions for females.
Fourth, using neutral emoticons in IM do not affect the receivers’ emotion in both the
simplex and complex task-oriented communication for all participants.
   The average value of intention to use emoticon in IM is 4.03 with standard deviation
of 0.66, which indicates a relative high intention to use. However, the difference of
intention to use emoticon in IM wan not significant with t-value value equals to -1.8 and
p-value equals to 0.076 between forty-six male participants (mean: 3.67, standard
deviation: .85) and thirty female participants (mean: 4.0, standard deviation: .64). Even
though the 0.05 significant-level was not accepted, there is a tendency that females still
had a higher intention to use emoticon to express their emotion when using IM that the
male did.
CONCLUSION AND SUGGESTIONS

       Drawing on the literature regarding the relationships of facial emoticon effect and
text cues in IM, this study intended to explore plausible potential effects of emoticons in
workplace. Research results show that IM text message containing emoticons did
generate different emotional effect than text messages without emoticons in some
scenarios. Therefore, the emoticon may serve the function of modified text messages.
Separate conclusions and suggestions related to the four research questions are briefly
summarized below.

Research question 3: Three types of messages
     After analyzing the message logs of IM in the case company, three main message
types which employees used IM to communicate most at work are concluded: (1)
task-oriented simplex communication such as for scheduling meetings, (2) task-oriented
complex communication such as for discussing or coordinating tasks, and (3) social
oriented such as for greeting by saying hi. This result confirms some of the previous
studies 5-6, 12-13. In addition to some study12 argued that IM has arrived as a financial
planning tool for customer, this study further supports that using IM in financial industry
can increase internal communication. According to this research scope, we suggest that
IM platform in workplace should at least embed functions for scheduling meeting,
discussing or coordinating tasks, and provide different emoticons for greeting.

Research questions 1 & 2: The effect of emoticons in task-oriented communication
     Based on the four findings regarding Table 4, some suggestions are proposed
accordingly. First, since positive emoticons significantly increased the emotion when
using IM in discussing and coordinating tasks, we suggest always using positive
emoticons in work coordination, especially when the a tendency for unpleasant emotions
between senders and receivers. Second, we suggest avoiding “flaming” emoticon in IM
since it may cause unexpected negative emotion between communicators even if the
original intention is just for kidding. Furthermore, we suggest the workplace IM system
prompts a “warning” message whenever a flaming emoticon is used to minimize some
unpleasant effects. Third, avoid using the neutral emoticon in unnecessary occasions
since it made no significant differences compared to the pure text message, which may
echo to the overuse claim by Walther and D'Addario’s study26 that its impact has been
diminished, either culturally/historically, or as an individual user is first entertained and
later bored with the cuteness of them all.

Research questions 4 & 2: Intention to use IM and gender difference
   First, based on our observation, we argue that employees are more likely to use
emoticon contained in text message in workplace when communicate with their colleges.
This result is in line with Rezabek and Cochenour’s study23 which suggested that the
most common, widely recognized emoticons are most useful for communication. It may
be that emoticons are a tie sign of sorts, signaling common knowledge. Furthermore, our
finding may echo Walther and D'Addario’s study26 that argued the usage of emoticons
can: (1) actually serve indirect socially communicative functions, (2) help writers of
e-mail to act as a self-signaling cue, prompting the writer to write in such a way that is as
expressive as the writers intends, and (3) help the writer to express, to check, and if need
be to edit, that which may be unclear during initial message production. Though, they
stated that emoticons are not communicative but generative.
   Second, even the test result did not support that female participants intended to use
IM more than the males did, we still argue that female has a higher tendency to use IM
in workplace. Because females feel more pleasant in both simplex communication and
complex communication, we suggest sending the positive emoticons with the text
message to female partners for making the communication more smoothly. If there is
some unpleasant emotion in the male only conversation group, then a mixed group
should be encouraged to reduce the negative emotion in workplace.
