Social facilitation can be defined as a tendency for individuals to perform differently when in the mere presence of others. Specifically, individuals perform better on simpler or well-rehearsed tasks and perform worse on complex or new ones. In relation to this, there are three main empirical relationships which are the activation, evaluation, and attention theories. The activation theory describes how we are physiologically aroused and how that affects our functioning. The evaluation theory relates to the systematic assessment of the worth or merit of some object. The attention theory takes into account possession in the mind including focalization and concentration of consciousness.
