We begin our adventure into group psychology with an important character: John Turner (1982). He saw a group as "two or more individuals who perceive themselves to be members of the same social category". Here, it's not just about being part of a crowd but acknowledging that you're part of a special club, like family, gender, or ethnicity.

💡 Example: If you've ever cheered for your school's sports team, then you've experienced Turner's group concept. You and your schoolmates might all consider yourselves part of the same "supporters" category!

Next, Brown (2000) extends the red carpet to others, stating that a group isn't just limited to its members. He thinks a group exists when outsiders can also recognize it. So, it's not just an exclusive party, but a happening everyone knows about.

💡 Example: Let's say you and your buddies form a band. According to Brown, your band becomes a 'group' when people outside your band acknowledge its existence. It could be your classmates, your teacher, or even your grandma!

Onward, we have Johnson and Johnson (1987) who add some sizzle to the group concept. They believe that a group is two or more individuals, aware of their group membership, aware of other members, and understand their interdependence as they aim to achieve mutual goals.

💡 Example: You're part of a school project team. Everyone knows they're in the team, everyone knows each other, and everyone understands that they need to work together to get that A+.
