Which of the following factors promotes a sense of shared experience within a group?

The correct choice is universality. Universality promotes a sense of shared experience within a group by highlighting commonalities among individuals. When group members recognize that they share similar feelings, experiences, or challenges, it fosters a connection and sense of belonging. This feeling of universality often creates a supportive environment where individuals feel less isolated and more understood, enhancing group cohesion.

In contrast, while imitative behavior can lead to conformity within a group, it does not necessarily create a shared experience—instead, it may lead to individuals simply mirroring each other's actions without deeper connection. Altruism focuses on selflessness and helping others, which is important for building group bonds but does not inherently relate to the shared experiences that foster a sense of community. The development of socializing techniques can improve interaction and communication within a group, but it does not directly address the foundational emotional connections that universality brings to the group dynamic.
