The traits of procrastination are obvious, more interesting are the traits of the procrastinator. Chronic procrastinators avoid revealing information about their abilities, prefer menial tasks, make poor time estimates, tend to focus on the past and do not act on their intentions. These characteristics have been related to low self-esteem, perfectionism, non-competitiveness, self-deception, self-control, selfcondence, depression and anxiety. From a neurobiology standpoint, the listed traits refer directly to the Ifunction in actions that consciously abuse the self. The importance of the I-function's interpretation of information and modication of behavior can be illustrated in the self-handicapping and decision-making components of procrastination. The complexity of procrastination has forced researchers to divide it into different types, the most pertinent in my opinion - behavioral and decisional. Behavioral procrastination is equated with self-handicap. Essentially, this self-handicap provides a means for further blame shifting, as could be seen in an example of a student doing poorly in an exam and using procrastination as an excuse. Studies on self-handicapping have shown that people use a wide variety of strategies in order to construct barriers for their success. The placing of these mental barriers is the work of the I-function manipulating the internal experience. Two studies conducted by Ferrari and Tice in a laboratory setting had participants (men and women) perform an identical task twice. In the rst study, participants were notied that they would be evaluated on their performance of the task. Time was allotted for practice or engaging in fun activities. Results found that participants procrastinated for 60% of the time. The second study described the identical task as a fun game. Results of activity during the time allotted showed that procrastinators, in comparison with non-procrastinators, spent the same of amount of time practices. Thus, the results suggest that procrastination was a behavioral self-handicap only when the task was deemed evaluative. The pervasive tendency of the self-handicap creates a cycle of selfdefeating behavior, which in turn send negative feedback to the I-function. Correspondingly, this selfinicted degradation and shame is translated into health problems. The second type of procrastination - decisional, is the pattern of postponing a decision when dealing with conicts and choices. People with high decisional procrastination display tendencies of perfectionism in taking longer to make decisions. Thus, the study by Ferrari and Dovido hypothesized that people with higher decisional procrastination, in comparison with people lower in decisional procrastination, seek out more information about a chosen alternative before making a decision. This hypothesis underscores the fear of error and necessity for perfection in people with high decisional procrastination. In addition, varying levels of decisional procrastination correlates to fundamental differences decisive strategies. The argument Ferrari and Dovido put forth associate decisional procrastination with caution and assurance of correctness, by collecting data, before making a decision. Clearly the implications of this form of procrastination differ from those of behavioral procrastination, characterized by distraction and avoidance.Decision-making or critical thinking, is an activity of the brain. Yet, it seems to me that people with high decisional procrastination take greater care in taking a step forward, thus the I-function would have to be considered in light of the fact that while a decision is being made, the thoroughness is connected to notions of concern, desire and fear; reecting individual traits.
