Behavior that occurs when two or more people interact is the subject of the study of behavior in groups. The presence of others may promote a variety of behavioral processes. The reasons for joining in groups are:security - by joining in groups, individuals ca reduce the insecurity of "standing alone". People feel stronger, have fewer self-doubts, and are more resistant to threats when they are part of a group: status - inclusion in a group that is viewed as important by others provides recognition and status for its members; self-esteem - groups can provide people with feelings of self-worth affiliation - groups can fulfil social needs power - what cannot be achieved individually often becomes possible through group action.
Group behavior is a generic human instinct, rather than the exclusive outcome of deeply-rooted traditions, religion or blood. Groups can have varying numbers of members, communication styles, and structures. Research has identified a few common requirements contributing to the recognition of individuals working in a collaborative environment to be considered a “group”:
Interdependence: In order for an individual of the collective to accomplish their part in the assigned task they depend, to some degree, on the outputs of other members of the collective. Social interaction: In order to accomplish the goal some form of verbal or nonverbal communication is required to take place amongst the members of the collective. Perception of a group: All members of the collective must agree they are, in fact, part of a group. Commonality of purpose: All the members of the collective come together to serve or attain a common goal.
