Various social processes in decision-making groups are considered detrimental to the quality of decisions. It is often assumed that removing the ability for groups to exert strong social influence on its members improves group decisions. Group decision support systems (GDSSs) are increasingly used to remedy the social faults of the decision-making process in groups. In these systems, anonymity is seen as a tool to reduce the impact of the group over its members, and therefore as the key to ... Continue Reading
The In-SIDE story: Social psychological processes affecting on-line groups
Lea, M., Spears, R., Watt, S., & Rogers, P. (2000). The InSIDE story: Social psychological processes affecting on-line groups. In T. Postmes, R. Spears, M. Lea, & S.D. Reicher (Eds.) SIDE-issues centre-stage: Recent developments in studies of de-individuation in groups. Amsterdam: North Holland.
CMC provides a new paradigm for research into general deindividuation phenomena that can usefully clarify some of the complexities in earlier deindividuation research as well as test the intervening processes that deindividuating contexts supposedly activate. For example, it enables one to manipulate anonymity and identifiability independently from physical isolation and co-presence. Conceptual distinctions between different forms of anonymity, such as visual anonymity and nominal anonymity (not ... Continue Reading

Breaching or building social barriers? SIDE effects of computer-mediated communication
Postmes, T. Spears, R. & Lea, M. (1998). Breaching or building social barriers? SIDE effects of computer-mediated communication. Communication Research 25, 689-715 (Special issue on '[Mis]communicating across boundaries').
Computer-mediated communication (CMC) is sometimes heralded for its power to break down social boundaries and to liberate individuals from social influence, group pressure, and status and power differentials that characterize much face-to-face interaction. This paper reviews research conducted within the framework of the social identity model of deindividuation effects demonstrating that this is not always the case. When communicators share a common social identity, they appear to be more ... Continue Reading
Representations of the group and group processes in CSCW research: A case of premature closure?
Lea, M & Giordano, R. (1997). Representations of the group and group processes in CSCW research: A case of premature closure? In G.C. Bowker, S. L. Star, W. Turner & L. Gasser, (eds.). Social Science, Technical Systems and Cooperative Work: Beyond the Great Divide (pp. 5-26). Mahwah, NJ: LEA
This paper considers the extent to which the representation of the 'group' and 'group processes' in the design of CSCW and groupware[1] systems reflects some of the wider preoccupations of the computing and telecommunications communities. This is part of our larger concern, which is that activity modelers tend to represent human activities in ways that are most appropriate to the tools and techniques they have at hand. This implies that their modelling activities go beyond viewing human ... Continue Reading

Panacea or panopticon? The hidden power in computer-mediated communication
Spears, R. & Lea, M. (1994). Panacea or panopticon? The hidden power in computer-mediated communication. Communication Research, 21, 427-459.
This article examines how interaction by means of computer-mediated communication (CMC) affects the operation of both status differentials and power relations, and attempts to identify the social psychological processes mediating the social and behavioral effects of these factors. The dominant assessment, particularly within social psychological analyses, is that CMC tends to equalize status, decentralize and democratize decision-making, and thus empower and liberate the individual user. This ... Continue Reading
Flaming in computer-mediated communication: Observations, explanations, implications
Lea, M., O’Shea, T., Fung, P. & Spears, R. (1992). 'Flaming' in computer-mediated communication: Observations, explanations and implications. In M. Lea (Ed.) Contexts of Computer-Mediated Communication. (pp. 89–112). London: Harvester-Wheatsheaf.
The notion that ‘uninhibited behaviour’ is associated with communicating via computer has gained a great deal of attention. One manifestation, ‘flaming’ (the hostile expression of strong emotions and feelings) has been widely reported in the research literature and commented on in the national press. Indeed, flaming has come to be regarded as symptomatic of the down-side of installing computer conferencing and electronic mail systems in organizations. Advice on how management can best avoid or ... Continue Reading
Paralanguage and social perception in computer-mediated communication
Lea, M. & Spears, R. (1992). Paralanguage and social perception in computer-mediated communication. Journal of Organizational Computing, 2, 321-342.
It is widely held that computer-mediated communication (CMC) filters out many of the social and affective cues associated with human interaction with consequent effects on communication outcomes and the medium's suitability for interpersonal tasks. The relationship between paralanguage and social perception in CMC in different social contexts in investigated in two experiments. In Study 1 it was hypothesized that there would be significant differences in subjects' perceptions of anonymous ... Continue Reading
Social influence and the influence of the social in computer-mediated communication
Spears, R. & Lea, M. (1992). Social influence and the influence of the ‘social’ in computer-mediated communication. In M. Lea (Ed.) Contexts of Computer-Mediated Communication. (pp. 30–65). London: Harvester-Wheatsheaf.
In this chapter we explore the social psychological dimensions of computer-mediated communication (CMC). We shall not be directly concerned here with the processes by which people choose CMC in preference to other communications media (see e.g., Fulk & Boyd, 1991, for a recent review), although it will become obvious that our argument has implications for media choice models. Rather we are interested here in the social psychological factors operating once "inside" CMC and particularly the ... Continue Reading

The book combines theoretical analyses of computer-mediated communication with discussion of its various forms and applications including electronic mail, ... Continue Reading
Computer-mediated communication, deindividuation, and group decision-making
Lea, M. & Spears, R. (1991). Computer-mediated communication, deindividuation, and group decision-making. International Journal of Man-Machine Studies, 34, 283-301 (Special issue on 'Computer supported cooperative work and groupware).
This paper discusses social psychological processes in computer-mediated communication and group decision-making in relation to findings that groups communicating via computer produce more polarized decisions than face-to-face groups. A wide range of possible explanations for such differences have been advanced, in which a lack of social cues, disinhibition, 'deindividuation' and a consequent tendency to antinormative behavior are central themes (Kiesler et al.,1984; Kiesler, 1986; Siegel et ...

Rationalist assumptions in cross-media comparisons of computer-mediated communication
Lea, M. (1991). Rationalist assumptions in cross-media comparisons of computer-mediated communication. Behaviour & Information Technology, 10, 153-172.
Users' comparisons between computer-mediated communication (CMC) and other forms of communication are of theoretical interest and have important implications for system design and implementation. This paper outlines the prevalent systems rationalist perspective on CMC, which sees the medium primarily as an efficient channel for information transfer in specific organizational tasks, and critically reviews the evidence which studies of users' perceptions and media preferences offer for this ...

Deindividuation and group polarization in computer-mediated communication
Spears, R., Lea, M. & Lee, S. (1990). De-individuation and group polarization in computer-mediated communication. British Journal of Social Psychology, 29, 121-134.
A computer-mediated communication system (CMCS) was used to explore the effects of de-individuation on group polarization. Reicher (1984) argued that de-individuating members of a group should increase the salience of group identity and hence normative behaviour, while de-individuating subjects treated as individuals should have the reverse effect. We extended this idea to the group-polarization paradigm and in addition independently manipulated group salience and de-individuation, which were ... Continue Reading
Investigating personal constructs of emotions
Parkinson, B. & Lea, M. (1991). Investigating personal constructs of emotions. British Journal of Psychology, 82, 73-86.
Forty-two first-year psychology students took part in an exploratory study of conceptions of emotions using Kelly's (1955) Repertory Grid technique. Each participant generated eight different personal constructs for comparing and contrasting eight different emotional states then rated these emotions on the basis of their own constructs. Analysis of the group data revealed five significant principal components. The first four of these components related to evaluation (positive versus ... Continue Reading
