any business transaction, and is particularly

of the paucity of rules and customs in regulating

online vendors are particularly challenged when
trying to build and attain consumer trust Indeed,
in contrast to face-to-face commerce and to other
applications of trust, which encompass a wide
range of emotions involving various types of
so-cial interaction with humans, there are typically
no interpersonal interactions in e-commerce,
neither direct nor implied Such interactions, or
even cues relating to them, are notably missing
from e-commerce Web sites Online shopping
may be viewed as lacking human warmth and
sociability The social aspect of shopping has been
shown to be a major contributor towards positive
emotions (Jones, 1999) that have been linked to
several important outcomes, such as increased
unplanned purchasing, increased spending, and
increased time spent in the store (Jones, 1999)

The aspect of trust has been examined over many years, however, most of the research on consumer trust focuses on consumers in Eng-lish-speaking countries and newly industrialized countries Trust in e-commerce research has been conducted almost exclusively in the US or Western Europe Considering the cultural, eco-nomic, social, and political differences between the developed and less developed countries, concerns have been raised in terms of whether research based in the US or Western Europe can
be generalized to other countries (Bagozzi, Wong, Abe, & Bergami, 2000) The global nature of the Internet raises questions about the effects of trust across cultures as well Although trust may be formed in a variety of ways, it depends on the cultural factors (e.g., societal norms, values, etc.) that guide people’s behaviors and beliefs Despite the differences national culture can cause in e-commerce behavior (Kacen & Lee, 2002), and despite e-commerce becoming global, research
on trust in e-commerce has to emphasize the possible effects of national culture For that, this study attempts to carry out a pilot case investiga-tion of our research objectives in Saudi Arabia;

This study researched the effect of adding media cues (video clips, photographs) of a presumed sales person’s face to the home page of an e-com-merce vendor, and considered the effect of social presence cues, also known as interpersonal cues, that are implicit in the media cue on users’ initial trust in the vendor (Research Objective 1) The majority of studies of online customer trust focus
on general trust as it develops between customers and online vendors over time and after repeated

Trusting beliefs (i.e., perceptions of Web vendor
attributes), and trusting intentions (i.e., intentions
to engage in trust-related behaviors with a Web
vendor) are based on the theory of reasoned
ac-tion (TRA) which was introduced by Ajzen and
Fishbein (1980) to analyze the psychological
pro-FHVVHVWKDWUHÀHFWREVHUYHGUHODWLRQVKLSVDPRQJ
beliefs, attitudes, intentions, and behaviors The
theory asserts that intention to perform behavior
is determined by the individual’s attitude toward
the behavior, and a person’s attitude is affected
by his/her beliefs TRA has been widely accepted
and applied to a broad range of disciplines and
contexts Existing empirical research has revealed

intentions (Chow & Holden, 1997; Macintosh

theoretical base in recent studies on trust
forma-tion (McKnight & Chervany, 2001; McKnight,
Cummings, & Chervany, 1998), especially in the
context of e-commerce (Jarvenpaa, Tractinsky, &

The Varying Dimensionality
of Trust
Although there is no complete agreement on the meaning of trust, it should be noted that the GLPHQVLRQVWKDWFRQVWLWXWHLWDUHFRQWH[WVSHFL¿F (Lewis & Weigert, 1985) As mentioned previ-ously, the literature does reveal that the concept
of trust tends to coalesce around a few key recur-ring concepts There must exist, for the trusting party, uncertainty about a potential or existing relationship that leads to a certain perception of risk or vulnerability This perception of risk is generally based upon the beliefs regarding spe-FL¿FIDFWRUVRIWKHWUXVWHH<HWUHFHQWUHVHDUFK KDVSULPDULO\IRFXVHGRQWKUHHVSHFL¿FIDFWRUV which may parsimoniously capture the concept
or the dimensions of trustworthiness—that is, ability, benevolence, and integrity (Jarvenpaa et al., 2000) Ability is the perceived skills, compe-tencies, and characteristics that enable a party to KDYHLQÀXHQFHZLWKLQDVSHFL¿FGRPDLQ0D\HUHW al., 1995) Benevolence is the trustor’s belief that the trustee wants to do good toward the trustor Integrity is the belief that the trustee adheres to a VHWRISULQFLSOHVWKDWWKHWUXVWRU¿QGVDFFHSWDEOH (Mayer et al., 1995) Perceptions of these three characteristics can lead to a willingness of the trusting party to depend or rely upon the trustee LQ H[SHFWDWLRQ RI D FHUWDLQ EHQH¿FLDO RXWFRPH
or that the trustee will not act opportunistically 7KHVH WKUHH VSHFL¿F IDFWRUV FDQ RIWHQ QRW EH observed directly, but need to be inferred from signals in the Web site interface In HCI trust research, signals given in the interface of a system that can form the basis of perceived trustworthi-ness are referred to as surface cues (Fogg, 2002) Certain literatures construct trust from different viewpoints and propose two main components or factors of trust: cognitive and affective or emo-tional (e.g., Shneiderman, 2000) Feng, Lazar, and Preece (2004) argue that the affective component
Trang 4of trust has been to some extent ignored in HCI
trust research, in particular in the domain of
e-commerce, where research is largely focused on
factors that contribute to cognitive trust, such as
security, error absence, and trust seals For retail
transactions, cognitive factors can increase the
FRQ¿GHQFHWKDWDWUDQVDFWLRQZLOOEHVXFFHVVIXOO\
completed Affective factors can increase the
feelings of attraction and trust
The distinction between cognitive and
emo-tional trust has received some support in an
empirical study on long-term work relationships
(McAllister, 1995), and strong support in a
face-to-face study that manipulated emotional trust
(Johnson-George & Swap, 1982) However, only
a few studies have examined affective-oriented
factors in an e-commerce (B2C) environment
This oversight of the affective element of trust
GRHVQRWUHÀHFWWKHLQFUHDVLQJFRQVLGHUDWLRQWKDW
is given to affective processes in multiple
disci-plines (e.g., marketing, psychology, sociology)
(Riegelsberger, Sasse, & McCarthy, 2005) For
example, marketing and advertising research are

processes In these disciplines it is well-known
that a consumer’s purchase decision depends on
rational process and on positive affective reactions

However, as mentioned in the research

this case, initial trust is the willingness to rely

of trust is an ongoing, dynamic process that is
LQÀXHQFHGE\LQWHUDFWLRQVEHWZHHQWZRSDUWLHV
However, we believe that initial trust beliefs can
also be formed without any prior experience or
interaction between the two parties The initial
trust beliefs may change with time and with re-peated interactions but they may also determine the extent to which such future interactions will take place (McKnight, Choudhury, & Kacmar, 2002)
In the context of e-commerce, initial trust is very important since Web-based companies must rely on their Web sites to represent them and to show their new customers that they are reliable and trustworthy Customers visiting a Web site IRUWKH¿UVWWLPHPD\UHO\KHDYLO\RQ:HEVLWH cues to form their initial trust beliefs, but they still lack the important information that develops through interaction over time (McKnight et al., 2002) Another important reason for establishing FXVWRPHUWUXVWWKURXJKWKH¿UVW:HEVLWHYLVLWLV the possibility of low switching costs for new cus-tomers compared with switching costs for expert customers (Reichheld & Schefter, 2000) Since the Web contains vast numbers of alternatives, either in vendors or in products, it has become very easy for customers to switch to a different RQOLQHVWRUHDIWHUWKHLU¿UVWYLVLW6RLWKDVEHFRPH

is critical
Social Presence and Online Trust
Applying trust-inducing features to the Web sites
of online merchants is the most effective technique for enhancing online trust Many researchers in HCI have begun to study trust in an online con-text Some researchers are focusing on the cues that may affect trust or convey trustworthiness
to users of Web sites In a sense, a Web site with trust-inducing features functions as a skillful salesperson for the company (e.g., Katsikas, Lo-pez, & Pernul, 2005)
Trang 5The trust phenomenon represents an
ongo-ing interpersonal interaction with another party,
whether a person or organization, over an extended
period of time Indeed, trust is typically built
gradually through extensive ongoing interactions
that enable individuals to create reliable
expecta-tions of what the other party may do (Luhmann,
1979) This social context is a key characteristic
of trust and trust-building behaviors, since trust,
in general, is built through constructive
interac-tions with other people (Luhmann, 1979) So, the
perception of a high degree of social presence,
implying direct or indirect human contact in the
relationship should, arguably, contribute to the
building of trust Extending this logic implies
that another way in which trust in an e-commerce
Web site may be built is through embedding the
Web site interface with a high social presence,
such as the perception that there is a medium of
communication that represents personal, sociable,
and sensitive human contact (Gefen & Straub,
2004)
6RFLDOSUHVHQFHKDVEHHQGH¿QHGDVWKHH[WHQW
to which a medium allows users to experience
others as being psychologically present (Fulk,
Schmitz, & Power, 1987) Social presence theory
by Short, Williams, and Christie (1976) describes
how the social context affects medium use; they see
social presence as a quality inherent in a
commu-nication medium Some researchers characterize
the social presence of a medium as its capacity
to transmit information about facial expressions,
posture, dress, and non-verbal cues (Short et al.,
1976) Others focus on the psychological
con-nection, where social presence is concerned with
warmth and whether it conveys a feeling of
hu-man contact or sociability (Yoo & Alavi, 2001)
While others still, focus on its close relationship
to information richness theory (Straub, 1994),
which concentrates on the interactivity of the
media Related to media information richness
theory (Straub, 1994), social presence theory
considers the extent to which a medium enables
a communicator to experience communication
partners as being psychologically present (Short et al., 1976) High social presence is typically found
in face-to-face communication However, medium richness can vary depending on circumstances (Zmud, Lind, & Young, 1990)
$VLJQL¿FDQWGLIIHUHQFHEHWZHHQRQOLQHDQG off-line shopping environments is that the latter involve a wide range of social interactions with humans through multiple sensory channels On-line shopping, on the other hand, primarily tends towards reducing the users’ affective or emotional factors through functional and performance based Web site design As such, online shopping may
be viewed as lacking human sociability, since it is more impersonal and automated than traditional RIÀLQHFRPPHUFH6RFLDOUHVSRQVHVWRFRPSXWHU technology (SRCT) research paradigm proposes that individual interactions with computers and other communication technologies are fundamen-tally social and natural, and people interact with computers and mediated stimuli using the same social attitudes and behaviors that they apply to other people The computers are social actors (CASA) paradigm (Nass, , Moon, & Carney,
LQLWLDWHG WKLV ¿HOG RI UHVHDUFK DQG XVHV theories and experiments derived from psychol-ogy, sociolpsychol-ogy, and communication to develop and validate theories Granted, online shopping Web sites typically involve no actual interaction with other people, however, Web site interface features have been suggested to help impact the perception of social presence cues, also known as interpersonal cues (discussed in more detail in the next section), that can be embedded in different ways Higher perceived social presence cues in a Web site may increase online trust through their effect on increased electronic communication since communication is a necessary element of constructive interaction (Gefen & Straub, 2004) Trust may increase when the trusted party shows behavior or other indicators in accordance with one’s expectations; the perception that the vendor
is embodying a high degree of social presence cues
in the Web site should increase consumer trust
Trang 6to the degree that such indications are expected
(Luhmann, 1979)
Social presence cues can convey a sense of
personal, sociable, and sensitive human contact,
so too should multimedia Web sites Indeed,
recently many online shopping Web sites have
used interface features and embedded social
pres-ence cues Advertising research has long relied
on imagery of friendly faces to build a positive
attitude towards products
Social Presence Cues
(Interpersonal Cues)
Social presence cues, also known as interpersonal
cues, are the signals that make a person aware of
the presence of other people (Short et al., 1976)
They are non-verbal and para-verbal
communica-tion methods and suggest participant appearance
each time a person interacts with another It may
be intentional or unintentional and it is part of
the rapid stream of communication that passes
between two interacting individuals Although
WKHUHDUHDQXPEHURIGH¿QLWLRQVRIVRFLDOSUHV-ence cues (interpersonal cues), in the broadest
sense it is communication that transcends the
bare elements of the written or spoken word The
interpretation of this communication has been
shown to have a central effect on participants’
perceptions of the event and can give information
about individuals’ backgrounds, motivations, and
emotional attitudes They augment spoken
mes-sages by helping people express their feelings or
thoughts through the use of their bodies, their
facial expressions, and their tone of voice and so
on (Mehrabian & Epstein, 1972) Psychological
studies have concluded that more than 65% of
the information exchanged during a
face-to-face interaction is expressed through non-verbal
means Fromkin & Rodman (1983) suggest that
up to 90% of the communicative process takes
place non-verbally The characteristics of the

of relevance in the debate on trust as they can
be interpreted as signals for trustworthiness
A trustor can form an impression of perceived trustworthiness of a trustee from the interpersonal cues he/she perceives in a face-to-face situation;
it works as inferences (Steinbruck, Schaumburg, Kruger, & Duda, 2002) Interpersonal cues lead
to an instant impression formation and thus have
an immediate impact on affective trust The dif-ferent types of cues differ in their reliability for trust assessments, and in how they are affected
by transmission over media (Riegelsberger et al., 2005)

Online Trust and Media Cue
Existing technologies allow for various represen-tations of interpersonal cues that are embodied in different kinds of media cues (e.g., photo, audio, video, embodied agent) to be integrated into one
Trang 7that classify and explain such media effects The
most common are social presence (Short et al.,
1976), media richness (Straub, 1994), and SRCT
(Nass, Moon, Fogg, Reeves, & Dryer, 1996) as
discussed in the previous section
The reduction in the number of interpersonal
cues when interacting online is seen as one of the
reasons for the lack of trust online (Shneiderman,
2000) This assumption is well supported by many
studies (e.g., Hassanein & Head, 2004) These
studies found that richer representations result
in higher awareness, preference, and
interper-sonal focus The most commonly used example
of visual interpersonal cues is the smile—this

immediate affective responses, and can form a
basis for affective trust
Thus, Web site interface elements such as
photographs, video clips, or synthetic voices can
create some level of social presence that may
enhance the affective trust compared to Web site
interfaces lacking such elements, and can therefore
be taken as an indication of the trustworthiness
of the trustee
There is much research on trust in e-commerce
vendors, while in contrast there are very few that
KDYHVSHFL¿FDOO\WHVWHGWKHHIIHFWRILQWHUSHUVRQDO
cues on trust (Al-Diri, Hobbs, & Qahwaji, 2006)
Some of the existing studies focused on the
ef-fect of synthetic interpersonal cues in avatars
(embodied agents); others investigated the effect
of displaying facial photos of humans on
e-com-merce sites All of these studies tested users’ trust
either in the form of quantitative questionnaires
or with qualitative interviews, using two
mock-ups of an e-commerce Web site, one with and
one without a photo or avatar (e.g., Bickmore &
Picard, 2005)
Video
In general, video is considered to be a rich media
cue and thus is considered to afford high social
presence cues as it transmits many visual and audio cues
In a study by Swerts, Krahmer, Barkhuysen, and Van de Laar (2003), on the effect of social presence cues on the detection of speaker uncer-tainty, they found the best discriminative ability for video with audio, compared to video only and audio only
Brosig, Ockenfels, and Weimann (2002) found that video with audio reached levels of cooperation that were close to those reached in face-to-face communication, even though they were reached after a longer time than in face-to-face com-munication
Horn, Olson, and Karasik (2002) in a study
on lie detection in job interviews found a better performance in discriminating lies from truthful statements in high quality video than in audio only
The study also compared low resolution video and low frame rate video They found that low resolution video, which suppresses detailed facial cues gives a performance as high-quality video and good performance in lie detection Horn et
al (2002) attribute this result to the reduction in truth bias in the absence of recognizable facial cues and the fact that the presence of facial cues may lead to a trusting reaction
A study by Van Mulken, Andre, and Müller (1999) investigated trust in advice This study varied the representation of an advisor (video, embodied agent, audio, and text only) and the quality of the advice Hence, the effect of media representation could be compared to the effect
of advice quality The study found a preference for high quality advice in all representations, but RQO\LQVLJQL¿FDQWLQGLFDWLRQRIDSRVLWLYHHIIHFW for video on the behavioral measures

Fareena, and Qualls (1999) found that

vendor Web sites Hence the following additional
research hypotheses were proposed:

in trustworthiness between Web sites with local
social presence and Web sites with foreign social
presence.
H-4: Saudi subjects will trust a Web site with
Saudi social presence (photo) more than a Web
site with Western social presence (photo).
EXPERIMENTAL METHODOLOGY
This study was designed as a one-factor
experi-ment manipulating three levels of Web site social
presence cues (or interpersonal cues) Each of
the four specially designed Web sites displayed
the same products but each represented different
vendors Only the media cues were manipulated on
the sites Thus, the study attempted to investigate
and examine the effects of the interpersonal cues
that can be manipulated by facial photographs,
video clips, and culture as control variables, which
used photos of Saudi and Western people when
forming the initial trust toward online vendors
In addition the study set out to measure some
auxiliary parameters
Experiment Participants
The experiment was conducted in an IT training institute in Riyadh, Kingdom of Saudi Arabia (KSA) The number of participants totaled 72 students Since online consumers are generally younger and more highly educated than conven-tional customers, student samples are close to the online consumer population (McKnigh et al., 2002) and therefore are representative of online shoppers (Gefen & Straub, 2004)
Experiment Material
An initial survey on the most popular online prod-ucts was carried out and found that laptops came

of interpersonal cues (e.g., Riegelsberger et al., 2002; Steinbruck et al., 2002) This experiment used semi-functional copies of existing vendors’ sites, chosen in consultation with the four most famous reviewer business sites; BizRate.com, ResellerRating.com, Price Grabber.com, and Epinion.com to facilitate the task of rating online shopping sites These services aggregate feedback from customers of e-commerce vendors based on post service and handling of privacy and security, which represents an aspect of vendor trustworthi-ness Western shopping sites were selected as they constitute a realistic scenario with relatively high risk, due to the vendor and the users being in two different countries The selection was based on the rating of high trustworthiness of the vendors and the number of reviewers of the selected site Also we made a usability test for the four vendors’ Web sites to check the usability index for each Web site and to make sure that all selected Web sites had almost the same usability criteria To do WKDWZHDVNHG¿YHSDUWLFLSDQWVWRXVHWKHFKHFNOLVW developed by Keevil (1998) to measure the

Data Collection
The research methodology of studies on trust
in e-commerce can be categorized into qualita-tive approaches, using either semi-structured interviews (e.g., Egger, 2001), or qualitative interviews in conjunction with user evaluation
