Introduction
Humans have a powerful desire to achieve a desirable motivation in the environment to process the available data. Zuckerman (1978) has done different studies on sensory deprivation. He found that those who were volunteers in his tests had some characteristics in common. They were extremely curious; they would like to have new experiences, and looked forward to accepting the risks for achieving these experiences. According to Zuckerman, sensation seeking is a property that is defined by the need for different senses, new, complicated, and different experiences, and desire to achieve the physical and social risks of these experiences (Franken, 2002, p. 343). Researches show that sensation seeking has a negative relationship with the level of (MAO). It means that the level of MAO is high in those who have low sensation seeking and it is low in those who have high sensation seeking.
