Procrastination is a common phenomenon that is easily recognised as one of the behaviours involved in not doing and avoiding work. However, work motivation theories have not devoted much attention to why people don't do things at work. Just as the study of abnormal behaviour is used to understand normal behaviour, so can the study of procrastination enhance the understanding of self-regulation. In this paper, procrastination is defined as the avoidance of the implementation of an intention. It is characterised by the avoidance of the intention and the preference for behaviour or thoughts that distract from the aversiveness of the intention. Individual difference variables, processes, and conditions are identified. Strategies to overcome procrastination are suggested.
