A Systematic Review of Social Presence: Definition, Antecedents, and Implications

“Studies suggest that higher levels of social presence are more beneficial in equivocal contexts wherein there is no “correct” outcome, such as negotiations (Daft and Lengel, 1986; Garau et al., 2003).”

“Incontrast to immersion, presence is the subjective experience of actually being in the mediated virtual environment (Slater and Wilbur, 1997; Witmer and Singer, 1998; Walther and Parks, 2002).”

“…with a virtual cat, view virtual humans in pain CA Canada Short et al., 1976; Nowak and Biocca, 2003 Engage in a video call with a remote participant using a telepresence robot AP Korea Choi et al., 2001 Short et al., 1976; Lombard, 1995 affordance(s) that influenced perceptions of social presence.”

“Telepresence can be defined as “the extent to which one feels present in the mediated environment, rather than in the immediate physical environment” (Steuer, 1992, p. 75).”

“Walther (1996) later expanded this theory to posit that people who communicate via text-based CMC platforms could, in some cases, achieve even higher levels of social presence than FtF interactants by carefully selecting which facets of themselves they wish to reveal (i.e., hyperpersonal model of…”

“When the perception of telepresence is strong, people should no longer be aware that their experiences are being mediated through technology (Lombard and Ditton, 1997).”

“William Gibson famously described cyberspace as a “consensual hallucination experienced daily by billions of legitimate operators, in every nation” ( Gibson, 1984, p. 51), portraying the social nature of “stepping through a barrier” (Slater and Wilbur, 1997, p. 2) into the virtual environment.”

“One significant concept that was not included due to this criterion was plausibility illusion (Slater, 2009).”

“In contrast to these medium-centric views of social presence, Walther (1992) argued that individuals are capable of adapting to different communication media, and can thus achieve their communication goals accordingly.”

“…al., 2013 Gerhard et al., 2001; Bailenson et al., 2005 Interact with a virtual cat, view virtual humans in pain CA Canada Short et al., 1976; Nowak and Biocca, 2003 Engage in a video call with a remote participant using a telepresence robot AP Korea Choi et al., 2001 Short et al., 1976; Lombard,…”

“As Blascovich et al. (2002) and Nass et al. (1994) argue, the appearance of the visual representation might simply be less important than behavioral social cues.”

“Both intimacy and immediacy are determined by verbal and nonverbal cues such as facial expressions, vocal cues, gestures, and physical appearance (Gunawardena and Zittle, 1997).”

“In their meta-analysis on the impact of immersion on telepresence, Cummings and Bailenson (2016) similarly found that general modality (e.g., comparing an HMD with head-tracking to a desktop computer) was one of the most frequently studied predictors of telepresence.”

“…age and social presence are as follows: Cho et al. (2015): 21– 44, Felnhofer et al. (2014): range not reported ( M = 23.34, SD = 2.73), Hauber et al. (2005): 19–63, Kim et al. (2004): not reported, Lim and Richardson (2016): 24–58, Richardson and Swan (2003): 19–63, Siriaraya and Ang (2012): 22–80.”

“Similarly, participants felt higher levels of social presence when their partner’s virtual representation was similar to his or her actual physical appearance (Jin, 2012), which resonates with findings regarding preference for consistency (Festinger, 1962).”

“As Blascovich et al. (2002) and Nass et al. (1994) argue, the appearance of the visual representation might simply be less important than behavioral social cues.”

“Finally, social presence or co-presence, refers to the “sense of being with another” (Biocca et al., 2003, p. 456) and is dependent on the ease with which one perceives to have “the access to the intelligence, intentions, and sensory impressions of another” (Biocca, 1997, p. 22).”

“In addition, researchers frequently hypothesize that increasing the salience of the mediated communication partner will naturally lead to more positive social outcomes (e.g., Fogg and Tseng, 1999; Hassanein and Head, 2007).”

“In addition, researchers frequently hypothesize that increasing the salience of the mediated communication partner will naturally lead to more positive social outcomes (e.g., Fogg and Tseng, 1999; Hassanein and Head, 2007).”

“…in a virtual bar, for example, participants reported contextual factors (e.g., appearance of bar, responsiveness of other characters, believability of dialogue with victim) as issues that brought them out of the virtual experience (“breaks in presence” Slater and Steed, 2000; Slater et al., 2013).”

“…and Benbasat (2010) found that participants were more likely to feel higher levels of social presence when they interacted with a virtual product recommendation agent whose appearance matched their ethnicity than one that did not, replicating findings based on social identity theory (Tajfel, 1979).”

“Of the nine studies identified in Table 1 ( de Greef and Ijsselsteijn, 2001; Yoo and Alavi, 2001; Sallnäs, 2005, Study 1 & 2; Bailenson et al., 2006; Bente et al., 2008; Homer et al., 2008; de Greef, 2014; Gimpel et al., 2016) that offered a comparison between audio-only and audio-video modalities,…”

“…an increase in social presence when the visual representation is more photographically or anthropomorphically realistic (e.g., Kang and Watt, 2013), others report no differences (e.g., Bailenson et al., 2001; Bente et al., 2008) or even a reduction in social presence (e.g., Nowak and Biocca, 2003).”

“Another study wherein social presence was operationalized to focus on the extent to which participants felt like they were together with their partner similarly found that social presence predicted attraction toward a physically embodied agent (i.e., robot; Lee et al., 2006a).”

“Of the nine studies identified in Table 1 ( de Greef and Ijsselsteijn, 2001; Yoo and Alavi, 2001; Sallnäs, 2005, Study 1 & 2; Bailenson et al., 2006; Bente et al., 2008; Homer et al., 2008; de Greef, 2014; Gimpel et al., 2016) that offered a comparison between audio-only and audio-video modalities,…”

“Asmall number of studies (e.g., Steed et al., 1999; Slater et al., 2000; Moreno and Mayer, 2004) have also compared immersive virtual platforms (e.g., HMD, cave automatic virtual environment; CAVE) with non-immersive ones (e.g., Desktop).”

“While there are a few exceptions (e.g., Qiu and Benbasat, 2005; Kim and Sundar, 2012), most of the current evidence indicates that people feel higher levels of social presence when there is a visual representation available, as can be noted in Table 1 .”

“…the most suitable job candidate (Management decision task) (hire most suitable job candidate) AP Germany Bouchard et al., 2013 Gerhard et al., 2001; Bailenson et al., 2005 Interact with a virtual cat, view virtual humans in pain CA Canada Short et al., 1976; Nowak and Biocca, 2003 Engage in a…”

“Finally, while we are aware of the strengths of behavioral and physiological measures and limitations of self-report measures (Slater, 2004; Friedman et al., 2006), we did not include studies that exclusively used behavioral and/or physiological measures of social presence to reduce variance and…”

“Subsequent studies have since shown that individuals adopt different strategies to convey socioemotional cues on platforms with relatively limited verbal and nonverbal cues (e.g., Ramirez et al., 2002; Antheunis et al., 2010).”

“The remaining half of the studies, however, suggests that participants perceive similar levels of social presence for both agents and avatars (Nowak and Biocca, 2003; von der Pütten et al., 2010; Dalzel-Job, 2014, Study 2; Kothgassner et al., 2014, 2017; Felnhofer et al., 2018).”

“…considering that multiple studies reviewed in this paper show that increasing immersive qualities does not linearly increase social presence (e.g., Moreno and Mayer, 2004; Sallnäs, 2005; Homer et al., 2008), it would be critical to understand if, and if so when, there is a ceiling effect of…”

“With the exception of one study (Sallnäs et al., 2000), all of the 10 studies that we identified found a positive relationship between haptic feedback and perceptions of social presence ( Table 1 ).”

“William Gibson famously described cyberspace as a “consensual hallucination experienced daily by billions of legitimate operators, in every nation” ( Gibson, 1984, p. 51), portraying the social nature of “stepping through a barrier” (Slater and Wilbur, 1997, p. 2) into the virtual environment.”

“Considering the fact that both gesture and posture have a significant influence on person perception in FtF contexts (Riggio and Friedman, 1986), it is possible that this added layer of technology in CMC will impact experiences of social presence.”

“Subsequent studies have since shown that individuals adopt different strategies to convey socioemotional cues on platforms with relatively limited verbal and nonverbal cues (e.g., Ramirez et al., 2002; Antheunis et al., 2010).”

“…not explore the impact of agency on social presence using a questionnaire, another study showed that participants showed higher physiological arousal while playing a computer game when they thought their opponent was an avatar compared to when they thought it was an agent (Lim and Reeves, 2010).”

“, immersive features) impact social presence are based on the assumption that certain affordances of a medium can increase or decrease social presence when all other circumstances are equal (e.g., Axelsson et al., 2001; Moreno and Mayer, 2004; Zhan and Mei, 2013).”

“Directly germane to this hypothesis, studies (Joinson, 2004; Hertel et al., 2008; Hammick and Lee, 2014) consistently show that less socially oriented individuals prefer interacting through a medium that is considered to be “leaner” (e.g., text-based CMC), while more socially oriented individuals…”

“Among the 10 studies that we identified, only two studies found significant differences in social presence between an immersive platform and a non-immersive one (Schroeder et al., 2001; Heldal et al., 2005).”

“While two studies (Bracken, 2005; Ahn et al., 2014) found that more immersive displays (i.e., higher definition, larger screen size) led to higher social presence, two others (Skalski and Whitbred, 2010; James et al., 2011) were unable to find a significant effect of display on social presence.”

“In their study on social agents, for example, Skalski and Tamborini (2007) invited participants to listen to a health message on blood pressure.”

“…in a virtual bar, for example, participants reported contextual factors (e.g., appearance of bar, responsiveness of other characters, believability of dialogue with victim) as issues that brought them out of the virtual experience (“breaks in presence” Slater and Steed, 2000; Slater et al., 2013).”

“For example, participants felt higher levels of social presence when they received haptic feedback as they lifted a (virtual) box with a partner compared to when such feedback was not available (Kim et al., 2004).”

“…studies reviewed in this paper show that increasing immersive qualities does not linearly increase social presence (e.g., Moreno and Mayer, 2004; Sallnäs, 2005; Homer et al., 2008), it would be critical to understand if, and if so when, there is a ceiling effect of immersion on social presence.”

“Researchers have also explored the impact of the personality of the virtual human (Pan et al., 2015), level of coherence to the user’s expectations (Skarbez et al., 2017), and the physicality of the virtual human (Chuah et al., 2013) on plausibility illusion.”

“…modalities (e.g., audio, video, avatar) also found that participants felt the lowest level of social presence when communicating via text-based CMC compared to “richer” forms of media, when given the same amount of time (e.g., Bente et al., 2008; Appel et al., 2012; Kim et al., 2013b).”

“Presence can be further divided into three distinct subcategories: telepresence (spatial presence), self-presence, and social presence (Lee, 2004).”

“Mühlbach et al. (1995) similarly found that participants felt greater social presence when they engaged in a video conferencing session using a stereoscopic display compared to a monoscopic one.”

“The studies that were identified in the present paper (Mühlbach et al., 1995; Takatalo et al., 2011; Kim et al., 2012; Ahn et al., 2014) suggest that the inclusion of depth cues increase social presence.”

“Asmall number of studies (e.g., Steed et al., 1999; Slater et al., 2000; Moreno and Mayer, 2004) have also compared immersive virtual platforms (e.g., HMD, cave automatic virtual environment; CAVE) with non-immersive ones (e.g., Desktop).”

“In terms of gender, the majority of the surveyed studies found that females experience higher levels of social presence compared to males (e.g., Giannopoulos et al., 2008; Johnson, 2011).”

“This is an important issue to consider when designing communication systems; more social presence may not always be better (Allmendinger, 2010).”

“…interpersonal evaluations (e.g., similarity attraction, social penetration theory, social identity theory, preference for consistency, etc.) to technology-mediated contexts to explore their relevance in interpersonal perceptions (e.g., Reeves and Nass, 1996; Jin, 2012; Verhagen et al., 2014).”

“More recent studies (Choi and Kwak, 2017, Study 2; Lee and Nass, 2004; Lee et al., 2005; Kim and Sundar, 2014; Daher et al., 2016; Kim, 2016; Robb et al., 2016) have examined how the number of people or the mere presence of another person who is aware of the virtual environment (i.e., social cues)…”

“The studies that were identified in the present paper (Mühlbach et al., 1995; Takatalo et al., 2011; Kim et al., 2012; Ahn et al., 2014) suggest that the inclusion of depth cues increase social presence.”

“These results are in line with the findings of Kim (2016) and Lee and Nass (2004), who also found that multiple virtual communicators increase feelings of social presence.”

“The age range of the seven studies that explored the relationship between age and social presence are as follows: Cho et al. (2015): 21– 44, Felnhofer et al. (2014): range not reported ( M = 23.34, SD = 2.73), Hauber et al. (2005): 19–63, Kim et al. (2004): not reported, Lim and Richardson (2016):…”

“Researchers have also found that social presence can be influenced by contextual and individual factors that impact perceptions of the psychological distance between interactants (e.g., Siriaraya and Ang, 2012; Kang and Gratch, 2014; Verhagen et al., 2014).”

“Similarly, Poeschl (2017) found that perceiving the virtual audience to be more socially present tended to lead to a worse speech-giving performance.”

“While this decision was made to achieve a higher level of internal validity, it led to the exclusion of research on important concepts, one of which is plausibility illusion (Slater, 2009; Slater et al., 2010).”

“…explored the provision of identity cues (e.g., name, portrait picture) as a contextual factor that influences social presence, and found that increasing the number of identity cues enhances feelings of social presence (Li et al., 2015; Feng et al., 2016; Choi and Kwak, 2017; Schumann et al., 2017).”

“…affordances of a medium (e.g., immersive features) impact social presence are based on the assumption that certain affordances of a medium can increase or decrease social presence when all other circumstances are equal (e.g., Axelsson et al., 2001; Moreno and Mayer, 2004; Zhan and Mei, 2013).”

“In contrast, it is possible that people will prefer lower levels of social presence when they are feeling more vulnerable; the success of text-based counseling and support systems (Dinakar et al., 2015) lends some support to this conjecture.”

“…explored the provision of identity cues (e.g., name, portrait picture) as a contextual factor that influences social presence, and found that increasing the number of identity cues enhances feelings of social presence (Li et al., 2015; Feng et al., 2016; Choi and Kwak, 2017; Schumann et al., 2017).”

“Although it is less common, a small number of studies also compare different types of virtual environments (e.g., Heldal et al., 2005; Johnsen and Lok, 2008).”

“Researchers have also explored the impact of the personality of the virtual human (Pan et al., 2015), level of coherence to the user’s expectations (Skarbez et al., 2017), and the physicality of the virtual human (Chuah et al., 2013) on plausibility illusion.”

“The present paper also identified five studies that explored the impact of absolute physical distance between interactants on feelings of social presence (e.g., Gajadhar et al., 2008; Croes et al., 2016; Järvelä et al., 2016).”

“As such, these individuals prefer to withdraw from social situations and stay in the background, rather than engaging in the conversation (Allmendinger, 2010; Cortese and Seo, 2012).”

“Although it is less common, a small number of studies also compare different types of virtual environments (e.g., Heldal et al., 2005; Johnsen and Lok, 2008).”

“In another study, participants felt lower levels of social presence when they were asked to observe their partner play a multiplayer game compared to when their partner observed them or when they played the game together with their partner (Herrewijn and Poels, 2015).”

“These results are in line with the findings of Kim (2016) and Lee and Nass (2004), who also found that multiple virtual communicators increase feelings of social presence.”

“For example, Daher et al. (2016) found that being exposed to a conversation between a virtual human and a real person prior to the study increased feelings of social presence for the participant after interacting with the same virtual human.”

“…interpersonal evaluations (e.g., similarity attraction, social penetration theory, social identity theory, preference for consistency, etc.) to technology-mediated contexts to explore their relevance in interpersonal perceptions (e.g., Reeves and Nass, 1996; Jin, 2012; Verhagen et al., 2014).”

“In perhaps one of the earliest studies of social presence, Christie (1974) conducted a study wherein 36 businessmen discussed an important business topic in groups of six, and found that participants reported higher levels of social presence for the multi-speaker phone system than for the standard…”

“While two studies (Bracken, 2005; Ahn et al., 2014) found that more immersive displays (i.e., higher definition, larger screen size) led to higher social presence, two others (Skalski and Whitbred, 2010; James et al., 2011) were unable to find a significant effect of display on social presence.”

“Social presence refers to “the salience of the interact-ants and their interpersonal relationship during a mediated conversation” (Oh et al. 2018, p.2).”

“For developing our theoretical framework, we combine fundamental insights of research on virtual reality (e.g., Oh et al., 2018) and RMSIs on the 2D internet (e.g., Brucks & Levav, 2022).”

“…of belonging to a meaningful learning community is emphasized as an important factor of students ’ learning experience in online learning, especially because it is difficult to make their social presence perceptible in the online environment (Joksimovi (cid:2) c et al., 2015; Oh et al., 2018).”

“SPT suggests that digital media vary in their ability to transmit social cues and thereby facilitate social presence through computer-mediated interpersonal communication (for a systematic review see Oh et al., 2018).”

“A systematic review (Oh et al., 2018) reported that approximately half of the studies surveyed showed an impact of agency on social presence, whereas in the remaining half of the studies the participants perceived similar levels of social presence regardless of the level of agency.”

“Studies in [25,26] reveal that SS interactions make students feel they are actual classmates in virtual worlds, and SI interactions provide feelings that their instructors are real people.”

“Research highlights the importance of social presence (Oh, Bailenson, & Welch, 2018), particularly in humans’ perceptions about machine agents (e.g., Spence, Westerman, Edwards, & Edwards, 2014).”

“Another important aspect of the environment is the psycho-social context, notably the social presence, i.e. the subjective experience of being in presence of a person with thoughts and emotions [111].”

“Social presence is increased when users are exposed to agents with human-like features (Oh et al., 2018).”

“…the finding of this study is the first to link the “ medium-centric social presence ” which is defined as the degree of social cues afforded by a digital environment as computer-mediated communication medium (Oh et al., 2018; Short et al., 1976; Yoo & Alavi, 2001) with multiple source effect.”

“, 1992), as well as both spatial and social presence, their measures of the latter were limited such that spatial presence was captured only through the coding of a single open-ended question related to overall user experience, while social presence—a notably multidimensional construct (Biocca et al., 2003; Cummings a…”

“Although gender is one of the most commonly examined individual factors in relation to social presence, scholars have not reached consensus on the gender effects (Oh et al., 2018).”

“…variables that contribute to higher versus lower levels of social presence and social influence in VR, including those related to the realism and agency of the virtual interaction partner and the degree of automaticity in the task being performed (Blascovich, 2002; Oh, Bailenson, & Welch, 2018).”

“As Oh et al. (2018) argued, there are a number of factors that impact social presence in an online environment, and one way to ensure presence and connection is for participants to both show their face and use eye contact.”

“In practice, there are conflicts between transparency and control, and compromises need to be made (Oh et al., 2018).”

“Furthermore, Oh et al. [38] show the potential for fidelity (i.e., visual realism) and consistency between behavioral and visual realism in pedagogical agents to be important sources of social presence and thereby possibly learning.”

“While there are many other determinants of social presence [14], not much is known about the importance of quality and naturalness of the character’s voice, although there is evidence that the close resemblance of an avatar’s voice to one’s own voice can lead to greater senses of immersion and…”

“outcomes, including trust, enjoyment, and attractiveness [53].”

“There are systematic reviews and meta-analyses conducted focusing on social presence [8, 30] and teaching presence [31], however, there is no systematic review specifically on cognitive presence.”

“Individuals experiencing (some) discomfort or unease during social interaction, or those who might feel uncomfortable in the presence of others, are likely to be less motivated to increase social interaction and connected-ness (Allmendinger 2010; Cortese and Seo 2012; Oh et al. 2018).”

“An additional avenue of future research is examining whether exposure using so-called social VR (Oh et al., 2018), that allow virtual gatherings through avatar representation of multiple users, evokes a stronger fear response, and whether the same effect can be achieved by blinding the patient to…”

“…presence mainly depends on sensory factors (e.g., visual representation of others, interactivity), or on the social context (e.g., physical proximity, social cues) (Oh et al., 2018) as well as on the task-related social interdependence between the actors (e.g., avatars) (Wienrich et al., 2018).”

“(For now, we exclude social presence, which merits an entire publication on its own, and has in fact received an excellent recent survey by Oh, Bailenson, and Welch [39].”

“Both academic researchers and practitioners are highly interested in studying the factors that increase social presence as it often predicts positive communication outcomes [25] [14] [32].”

“For mediated interactions, while there is considerable research on the construct of social presence [15, 131], there is not a widely accepted definition for a mediated genuine feeling of connection that might be facilitated by such social presence.”

“For a comprehensive account of the recent literature on social presence in VR, we encourage the reader to check [46].”

“This feeling and perception of interacting with a human being is also known as ’social presence’ [6], [14], [15].”

“Several studies have investigated the effects of the presence and the realism of the partner’s avatar in CVEs with results indicating that people feel higher levels of social presence when there is a visual representation available [20].”

“The animations represented different activities (e.g., typing on a laptop, talking to each other, moving their hands) to make them appear more life-like and recreate real-world social situations, increasing their perceived social presence [49].”

“…presence defined as ‘‘the subjective experience of being present with a ‘‘real’’ person and having access to his or her thoughts and emotions’’ 16 (p1), interactivity can increase feelings of social presence 17 through enhancing the perception that one is talking with an intelligent being…”

“This may play a key role in how the metaverse facilitates learning by providing higher degrees of social presence [37, 67, 68], enjoyment [69] and cognitive abilities [69, 70].”

“Virtual embodiment was also found to be important for distance perception [Mohler et al. 2010; Ries et al. 2008] and collaboration style [Pan and Steed 2017].”

“…(e.g. experiencing mutual gaze), and despite a lack of uniformity in definition and measurement, scholars largely acknowledge that social presence extends beyond mere mutual awareness and is in fact a multidimensional construct (see Oh et al., 2018 for a systematic review of social presence).”

“In contrast to previous research that predominantly emphasizes the positive effects of anthropomorphic robots (Blut et al. 2021; Oh, Bailenson, and Welch 2018; Yoganathan et al. 2021), this study reveals a critical insight: consumers attribute social agency to these robots with human-like social…”

“…the operationalization of these dimensions may vary, studies suggest that co-presence and social presence are closely associated with outcomes including overall satisfaction with the media (Bulu, 2012), attraction (Lee et al., 2006), and behavioral intentions (Kang and Kim, 2022; Oh et al., 2018).”

“Studies have shown that social presence is related to various positive communication outcomes, such as persuasion and attraction (Oh et al., 2018).”

“The sense of social presence increases when users perceive the robot as an agent having social attitudes and social behaviors [41, 68].”

“Although patients reported positive perceptions of this audio-only VR therapist, visually and behaviorally realistic VR therapists have been shown to evoke greater perceived presence [135].”

“3a)—the sense that one is interacting with an intentional, engaged agent (Oh et al., 2018).”

“One of the most common de fi nition of presence de fi nes it as subjective experience of being in the virtual environment (Slater and Wilbur, 1997; Oh et al., 2018).”

“Based on the various antecedents that impact social presence proposed by Oh et al. (2018), future research could explore the influences of other factors on different dimensions of social presence in live streaming commerce.”

“Socialpresence for each of the media platforms the attendees used during the conference was measured with four 5-point Likert-type items that were adapted from earlier literature (Oh et al., 2018).”

“If relevant in the context, avatars should provide mimics, one of the most important stimuli to contribute to sociality [68, 81].”

“SLRs often have a rather narrow focus on one specific delimitable characteristic or dimension, for example on Social Presence in virtual environments [143] (here the authors additionally focus on “predictors of social presence”), on technologies which support awareness in collaborative systems [120], or on explanation…”

“In addition, (bodily) acting within a virtual social context may create a sense of being together (co-presence), or interacting with others (social presence) while actually being physically remote (Short et al., 1976; Garau et al., 2005; Parsons et al., 2017; Oh et al., 2018).”

“For socially interactive robots, social presence depends on the ability to communicate expected social behaviors through the robot’s available modalities [6], [25].”

“Unlike the PC-based virtual worlds where users rely on a mouse and a keyboard to manipulate their avatars on a 2D screen [40], social VR afords embodied frst-person avatar experience and simulates “face-to-face” interactions via full-body tracking and synchronous verbal communications [47, 51, 73].”

“…initially conceptualized as the experience of emotional and psychological closeness between people during mediated communication (Short et al., 1976), or more recently as the level of perceptual salience of other social actors as “ real ” (for a review, see Cummings & Wertz, 2023; Oh et al., 2018).”
