When people are faced with the same set of situational factors, we know they don;t always perform in the same way and we have previously termed this dispositional factors. But where do these differences stem from? The learning approach would suggest that these differences come from our reinforcement histories, that is the pattern of environmental influences and experiences that we have been exposed to, for example, the patterns of rewards and punishments that we have receive and the role models  we may have observed and imitated. These differences in our experiences in the world mean that similar situations may lead to differing outcomes.
