Briefly summarize the main points of "social identity theory," as explained by Hogg, Terry and White in their article, "A Tale of Two Theories". In their article, these authors analyze four ways in which "social identity theory" differs from "identity theory":
(1) level of analysis; (2) intergroup behavior; (3) roles and groups; and (4) social context and identity salience.
Explain the first three of these four.

Level of analysis- Social identity theory is analyzed from the view point of sociological perspective whereas identity theory is expressed from psychological perspective. Inter group behavior- It differs widely in social identity theory rather than identity theory. Roles and groups- It plays a vital role social identity theory not in identity theory.

Explanation:

The main four criteria of differences in between social identity theory and identity theory are:1) level of analysis; (2) inter group behavior; (3) roles and groups; and (4) social context and identity salience.

Level of analysis means on the basis of which criteria different levels of society will be discussed.

Inter group behavior indicates the differences in the opinion, culture, language in between various group.

Roles and group of each clan in a society has a wide role in determining social identity.
