Group:

Xiao (198 1) believes that a group is composed of two or more individuals who interact and influence each other. He pointed out that all groups have a common feature, that is, the members of the group interact with each other and the group exists for a reason. For example, in order to meet a certain need, provide information or achieve a unified goal. It can be seen that according to Xiao's definition, the audience in the same cinema and the passengers on the same plane can only be said to be an aggregate, not a real and interactive group.

Baker (back, 1977) believes that the key to understanding the concept of group is that all its members must have observable and meaningful connections; The interaction between individuals makes people become a group and strive for a common goal. More and more researchers believe that group is a mixture of all the above meanings or more. Others think that a group is a group of people who are closely linked in some way. Barron et al. (2003) thinks that a group is a group of people who are linked by some kind of ties and have different degrees of cohesion.
