Self-categorization Theory
Self-categorization theory is a theory of social categorization that includes categorization of the self as a key feature. The theory was developed by John Turner and colleagues, and along with social identity theory it is a constituent part of the social identity approach...

.

This term is an attempt to avoid confusion where self-categorization theory is mistakenly perceived to be a subset of social identity theory, or vice versa. Instead these theories should be thought of as overlapping in the manner demonstrated in Fig 1. That is, while there are similarities, self categorisation theory has greater explanatory scope (i.e. is less focused on intergroup relationships specifically) and has been investigated in a broader range of empirical conditions. Self-categorization theory can also be thought of as developed to address limitations of social identity theory. Specifically the limited manner in which social identity theory deals with the cognitive processes that underpin the behaviour it describes.

Although this term may be useful when contrasting broad social psychological movements, when applying either theory it is thought of as beneficial to distinguish carefully between the two theories in such a way that their specific characteristics can be retained.

Leadership

According to the social identity approach, leadership is a function of the group instead of the individual. Individuals who are leaders in their groups tend to be closer to the prototypical group member than are followers. Additionally, they tend to be more socially attractive, which makes it easier for group members to accept their authority and comply with their decisions. Finally, leaders tend to be viewed by others as the leader. In this final distinction, group members attribute leadership traits to the person and not the situation, furthering the distinction between the leader and others in the group by viewing him or her as special. Consistent with this view of leadership, researchers have found that individuals can manipulate their own leadership status in groups by portraying themselves as prototypical to the group.

Social identity model of deindividuation effects

The social identity model of deindividuation effects (SIDE) was developed from further research on the social identity theory and the self-categorization theory, further specifying the effects of situational factors on the functioning of processes proposed by the two theories. The SIDE model uses this framework to explain cognitive effects of visibility and anonymity in intra-group and inter-group contexts. The model is based on the idea that the self-concept is flexible and different in different situations or contexts. The theory consists of a range of different self-categories that define people as unique individuals or in terms of their membership to specific social groups and other, broader social categories based on the context of the situation. The SIDE model proposes that anonymity shifts both the focus of self-awareness from the individual self to the group self and the perceptions of others from being mostly interpersonal to being group-based (stereotyping).

Research has suggested that visual anonymity not only increases negative behavior towards others, but also can also promote positive social relations. In one study, all volunteers participated individually in group discussion based on three different topics. In the visually anonymous condition, all communications between participants were text-based while in the visually identifiable condition, the communication was also supplemented by two-way video cameras. The study resulted in the findings that showed anonymity significantly increased group attraction.

Intergroup emotion theory

Intergroup emotion theory further expands on the concept of personally significant group memberships as posed by social identity and self-categorization theories. This theory is primarily based on the concept of depersonalization and the interchangeability of the self with other ingroup
Ingroups and outgroups
In sociology and social psychology, ingroups and outgroups are social groups to which an individual feels as though he or she belongs as a member, or to which they feel contempt, opposition, or a desire to compete. People tend to hold positive attitudes towards members of their own groups, a...

members. This causes cognitive representations of the self and the group to become inevitably connected, and therefore the group obtains an emotional significance. This means that individuals not only categorize themselves as members of the ingroup but also "react emotionally when situations or events affect the ingroup". For example, people often report that their group is being discriminated against, even though they feel that they personally are not subject to that discrimination.
