Explain the specific factors that contribute to achievement motivation and critically evaluate its affect on performance and on following an active and healthy lifestyle.

Achievement motivation links personality with the degree of competitiveness shown by an individual, and has several factors that contribute towards it for example the probability of success, incentive value of success, personality and attribution. According to Atkins and McCelland there research concluded, that motivation is predicted through a combination of personality and situational factors.

Firstly a situation comprises the probability of success this is to the extent to which success is likely, for example more likely that success will be achieved if task is easy, so performers with TAS behaviours would be more inclined to do the task, where as a TAF performer if the task is too difficult is more likely not to do the task as behaviour is likely. Another situational factor, which contributes to achievement motivation, is the incentive value of success, this is experienced by the individual after success has been achieved, for example the hard the task the higher the incentive value to succeed.
Personality according to Atkns and McCelland, is also contributes towards achievement motivation., they stated that there are 2 personality types NACH or NAF, which performers develop in these situations. They believe taking into account the situational factors, a personality will either be High NACH which is the high need to achieve, and aspire towards mastery orientation whereas a performer with a High NAF they will have a low need to achieve and apdot learned helplessness characteristics.
Taking in both the situational and personality factors, high achievers (high nach), are likely to display approach behaviours and mastery orientation characteristics, which the strong motive to succeed,
