Which concept refers to individuals modifying their behavior due to real or imagined group pressure?

The concept that refers to individuals modifying their behavior due to real or imagined group pressure is conformity. Conformity involves changing one's beliefs or actions to align with those of others, often in response to social norms or expectations. This can occur in a variety of contexts, such as in a group setting or within societal expectations, where individuals may feel the need to fit in or avoid standing out.

In understanding conformity, it's important to note that this process can be influenced by various factors, including the desire for acceptance, the fear of rejection, or simply the social influence exerted by a group. The individual may not always actively agree with the group's viewpoint but still adjusts their behavior to align with it. This adjustment can be subtle and may occur even if the individual is aware of this external pressure.

The other concepts—compliance, cooperation, and negotiation—each have distinct meanings and contexts. Compliance usually refers to following a request or demand from others, not necessarily driven by group norms but by authority or specific requests. Cooperation involves working together towards a common goal, emphasizing teamwork rather than individual behavioral changes due to group pressure. Negotiation refers to discussions aimed at reaching an agreement, focusing on dialogue rather than behavioral modification in response to social influence.
