Lesson 6 - Life In Groups

This is a group, a collection of people who share attributes, identify with one another and interact with each other. 

This group of marathon runners represents Aggregate.  They are all sharing the same physical location but know nothing about each other. They are only in contact because they are running the same race.

 This is my primary group. I am closely associated with them and we all belong together.

 My sisters soccer team is a secondary group.  They are together for a reason and for a specific activity.  They interact only to accomplish the task of playing together as a team.

My youngest sister and her two friends are a triad. They will continue to exist even if one is no longer in the picture.  They are more stable at the cost of intimacy.

These best friends are a dyad. They will have a closer bond withe each other than the triad does but is also more unstable because if one person leaves the group, it no longer exists.
