Psychology is important as it is concerned with the study of behavior and mental processes and at the same time, it is also applied to many different things in human life. Through psychology, we are able to understand and determine how the mind and body of an individual works. Mental toughness is having the natural or developing psychological edge that enables you to normally cope better than your opponents with the many demands (competition, training lifestyle) that sports places on a performance and specifically to be more consistent and better than your opponents in remaining determined, focused, confidence and in control under pressure (Jones et al 2002) mentally tough competition also have the unique ability to exert control over the varying demands placed upon them in training and their personal life. Lopez (1977) has defined a decision as a judgment, a final resolution of a conflict of needs, means or goals; and a commitment to action made in face of uncertainly, complexity and even irrationally. Therefore decision making is an important part of all science-based professions, where specialists apply their knowledge in a given area to making informed decisions. Decision-making is an integral part of everyday life and level of self-confidence is related to the time it takes to make a decision. Myers (1962) indicated that a person's decision-making process depends to a significant degree on their cognitive style; as in most decision-making situations, an individual faces different degrees of uncertainty. In probabilistic terms, this situation is called ambiguity.
