Hackman proposed that teams and work groups are successful when specific conditions are met. Specifically, when members of the team and their clients are satisfied, team members are able to grow professionally, and team members find their work meaningful.

between majority and minority group members.
There are three psychological processes underlying the
contact hypothesis: learning about the outgroup through direct contact, fear and anxiety reduction when interacting with the outgroup, and increased ability to
perspective take and empathize with the outgroup which results in reduced negative evaluation. These processes take place optimally when four conditions are met. Groups must:
# Have relatively equal status
# Have shared goals
# Be able to cooperate with each other
# Recognize an authority or law that supports interactions between the two groups.
Some researchers have critiqued the
contact hypothesis, specifically its generalizability and the fact that intergroup contact can result in an increase rather than decrease in prejudice.

superordinate, cooperative goal was imposed that required the groups to work together resulted in decreased feelings of

The Robbers Cave Experiment was conducted in 1954 and was designed to test theories of intergroup conflict. The experiment was designed so that there were two groups of campers, the Eagles and the Rattlers. As the independent variable, experimenters devoided the campers of certain rewards and resources. It was found that when there is a limited amount of resources, there will inevitably be conflict between the groups to fight for those resources. Each group in this experiment also did not see the other group as more or even equally favorable as their own. In the end, this competition eventually led to violence and was broken up only through working together (contact theory). This showed that even if you begin unaffiliated with a group, as soon as you find a group that you associate yourself with (become part of in-group), you will take on the qualities and characteristics of the individuals in that group; whatever that group norm is, you inherent as your own.

to describe how individuals and groups behave differently depending on their environmental context. In terms of intergroup relations, he applied his formula of ''B'' = ''ƒ''(''P'', ''E'') - behavior is a function of the person and their environment - to group behavior. The theory behind this formula, which emphasizes that context shapes behavior in conjunction with an individual's motivations and beliefs, is a cornerstone of social psychological research.

social judgment theory, a model for
self-persuasion that explains how individuals perceive and evaluate new ideas by comparing them with current attitudes. The theory sought to outline how individuals make sense of persuasive messages and how this can in turn influence individual and group beliefs.
Solomon Asch
Solomon Asch's work on conformity in the 1950s also helped shape the study of intergroup relations by exploring how the social pressures of group membership influence individuals to adhere their behavior, attitudes, and beliefs to
group norms.
The results of these studies showed that individuals could yield to group pressure, with subsequent studies investigating the conditions under which individuals are more or less likely to conform to the behavior of the group. Asch's research, along with
Stanley Milgram's shock experiments, shed light on the psychological processes underlying
obedience
