Procrastination involves the act of delaying something over which we have direct control. Whilst procrastination has often been associated with the pleasure principle (we do things we like first, and do things we like less, later), the scientific definition of procrastinating behavior requires that the behavior be counterproductive, needless, and delaying.
Hyperbolic discounting describes our tendency to reduce the importance of the future in our decision making. The further in time that a consequence will occur, the less bearing it will have on our immediate choices. We often make decisions that our future selves would not have made, and our discount rates fluctuate based on the amount of time involved in the retrieval of rewards and punishments.
For example, most people choose 1 dollar today over 3 dollars tomorrow, but 3 dollars in one year plus one day over 1 dollar in one year.
Out of sight, out of mind! Events or objects that are distant (temporally, spatially, socially) are construed more abstractly than proximal events or objects. We assess the relevance of potential events in our environment based on a number of factors related to how psychologically close we feel to them.
