Computer-Mediated Communication Impersonal, Interpersonal, and Hyperpersonal Interaction

While computer-mediated communication use and research are proliferating rapidly, findings offer contrasting images regarding the interpersonal character of this technology. Research trends over the history of these media are reviewed with observations across trends suggested so as to provide integrative principles with which to apply media to different circumstances. First, the notion that the media reduce personal influences—their impersonal effects—is reviewed. Newer theories and research are noted explaining normative “interpersonal” uses of the media. From this vantage point, recognizing that impersonal communication is sometimes advantageous, strategies for the intentional depersonalization of media use are inferred, with implications for Group Decision Support Systems effects. Additionally, recognizing that media sometimes facilitate communication that surpasses normal interpersonal levels, a new perspective on “hyperpersonal” communication is introduced. Subprocesses are discussed pertaining to receivers, senders, channels, and feedback elements in computer-mediated communication that may enhance impressions and interpersonal relations.

Interpersonal Effects in Computer-Mediated Interaction A Relational Perspective

Several theories and much experimental research on relational tone in computer-mediated communication (CMC) points to the lack of nonverbal cues in this channel as a cause of impersonal and task-oriented messages. Field research in CMC often reports more positive relational behavior. This article examines the assumptions, methods, and findings of such research and suggests that negative relational effects are confined to narrow situational boundary conditions. Alternatively, it is suggested that communicators develop individuating impressions of others through accumulated CMC messages. Based upon these impressions, users may develop relationships and express multidimensional relational messages through verbal or textual cues. Predictions regarding these processes are suggested, and future research incorporating these points is urged.

Interpersonal Effects in Computer-Mediated Interaction A Meta-Analysis of Social and Antisocial Communication

This study examined the effects of time restriction on social interaction in computer-mediated communication through a meta-analysis of applicable research. Time was defined as whether subjects were restricted or unrestricted in their opportunity to exchange messages. Studies were included that assessed either of two outcome variables: socially oriented (as opposed to task-oriented) communication, and negative / uninhibited communication. Hypotheses were derived from Walthers social information processing perspective. Meta-analytic tests supported the hypotheses on social communication. Although no effects were found on negative / uninhibited communication, a reexamination of original studies suggests caution regarding previous findings.

Selective self-presentation in computer-mediated communication: Hyperpersonal dimensions of technology, language, and cognition

The hyperpersonal model of computer-mediated communication (CMC) posits that users exploit the technological aspects of CMC in order to enhance the messages they construct to manage impressions and facilitate desired relationships. This research examined how CMC users managed message composing time, editing behaviors, personal language, sentence complexity, and relational tone in their initial messages to different presumed targets, and the cognitive awareness related to these processes. Effects on several of these processes and outcomes were obtained in response to different targets, partially supporting the hyperpersonal perspective of CMC, with unanticipated gender and status interaction effects suggesting behavioral compensation through CMC, or overcompensation when addressing presumably undesirable partners.

The Impacts of Emoticons on Message Interpretation in Computer-Mediated Communication

Emoticons are graphic representations of facial expressions that many e-mail users embed in their messages. These symbols are widely known and commonly recognized among computer-mediated communication (CMC) users, and they are described by most observers as substituting for the nonverbal cues that are missing from CMC in comparison to face-to-face communication. Their empirical impacts, however, are undocumented. An experiment sought to determine the effects of three common emoticons on message interpretations. Hypotheses drawn from literature on nonverbal communication reflect several plausible relationships between emoticons and verbal messages. The results indicate that emoticons’ contributions were outweighed by verbal content, but a negativity effect appeared such that any negative message aspect—verbal or graphic—shifts message interpretation in the direction of the negative element.

Is a Picture Worth a Thousand Words? Photographic Images in Long-Term and Short-Term Computer-Mediated Communication

This article asks whether, and when, participants benefit from seeing each others faces in computer-mediated communication. Although new technologies make it relatively easy to exchange images over the Internet, our formal understanding of their impacts is not clear. Some theories suggest that the more one can see of ones partners, the better one will like them. Others suggest that long-term virtual team members may like each other better than would those who use face-to-face interaction. The dynamic underlying this latter effect may also pertain to the presentation of realistic images compared with idealized virtual perceptions. A field experiment evaluated the timing of physical image presentations for members of short-term and long-term virtual, international groups. Results indicate that in new, unacquainted teams, seeing ones partner promotes affection and social attraction, but in long-term online groups, the same type of photograph dampens affinity.

Let Me Count the Ways The Interchange of Verbal and Nonverbal Cues in Computer-Mediated and Face-to-Face Affinity

Alternative views of computer-mediated communication suggest that it is devoid of affective cues and interpersonal expression, or that the translation of affect into verbal cues facilitates relational communication. Little research has examined basic affective communication online, mirroring a dearth of empirical research identifying spontaneous affective verbal cues in face-to-face interaction. An experiment prompted participants to enact greater or lesser affinity in face-to-face or synchronous computer chat dyads in order to assess the proportion of affect expressed verbally online compared to that which is verbal offline and the specific behaviors that account for affective communication in each channel.Partners’ ratings demonstrated affective equivalency across settings. Analyses of the verbal, kinesic, and vocalic behaviors of face-to-face participants and verbal transcripts from computer sessions revealed specific cues in each condition that led to these ratings. Results support a primary but previously untested proposition in the social information processing theory of mediated interaction.

Impression Development in Computer-Mediated Interaction.

This study reports an experiment of the effects of time and communication channel— asynchronous computer conferencing versus face‐to‐face meetings—on the development of interpersonal impressions. Prior research on interpersonal aspects of computer‐mediated communication suggests that the absence of nonverbal cues inhibits interactants’ ability to form impressions of each other and that without these cues communication is generally depersonalized. Past research is criticized for failing to incorporate social cognitive, temporal, and linguistic perspectives on communication via computer technology. A social information processing perspective suggests different rates and patterns of impression development using alternative media. In this experiment, computer conferencing and face‐to‐face groups addressed three tasks over several weeks. Results showed that computer‐mediated groups gradually increased in impression development to a level approaching that of face‐to‐face groups. New perspectives on social cogni...

Nonverbal cues in computer‐mediated communication, and the effect of chronemics on relational communication

Computer‐mediated communication (CMC) has been described as lacking nonverbal cues, which affects the nature of interpersonal interaction via the medium. Yet much CMC conveys nonverbal cues in terms of chronemics, or time‐related messages. Different uses of time signals in electronic mail were hypothesized to affect interpersonal perceptions of CMC senders and respondents. An experiment altered the time stamps in replicated e‐mail messages in order to assess two time variations: (a) the time of day a message was sent and (b) the time lag until a reply was received. Results revealed significant interactions among these variables, and the task‐orientation or socioemotional orientation of the verbal messages, which affected perceptions of communicators’ intimacy/liking or dominance/submissiveness. Findings extend recent theories regarding social attributions and the adaptation of social cues in CMC behavior.

Maintaining and Restoring Privacy through Communication in Different Types of Relationships

This investigation analysed the kinds of communicative acts that are considered privacy-invading, which communication strategies are used to restore privacy when it has been violated and how relationship type affects communication of privacy. A preliminary self-report survey and a pilot study employing open-ended interviews (n=43) led to the development of a questionnaire in which respondents (n=444) rated 39 possible actions on invasiveness and rated the likelihood of using 40 different tactics to restore privacy. Types of privacy violations formed five dimensions: (1) psychological and informational violations, (2) non-verbal interactional violations, (3) verbal interactional violations, (4) physical violations and (5) impersonal violations. Strategies used to restore privacy included: (1) interaction control, (2) dyadic intimacy, (3) negative arousal, (4) distancing, (5) blocking and (6) confrontation. Significant differences emerged across doctor-patient, employeremployee, teacher-student, parent-child, spouse-spouse and siblingsibling relationships.
