Though the studies examining running time were consistent with the arousal explanation, they did not directly measure physiological arousal. Robert Zajonc, in 1965, with reference to the Yerkes-Dodson’s law, proposed the Activation Theory for social facilitation, arguing that the presence of others causes a level of arousal which enables people to perform better.
