Over the years, scientists have determined that not all procrastination is the same. The first type is chronic procrastinators whom exhibit a combination of qualities from the other, more specialized types of procrastinators. "Arousal" types are usually self-proclaimed "pressure performers" and relish the exhilaration of completing tasks close to the deadline. "Avoider" types procrastinate to avoid the outcome of whatever task they are pushing back - whether it be a potential failure or success. "Avoider" types are usually very self-conscious and care deeply about other people's opinions. Lastly, "Decisional" procrastinators avoid making decisions in order to protect themselves from the responsibility that follows the outcome of events.
