Ja dat zou heel makkelijk zijn. Ik zou mijn best ook niet meer doen.

Angramar Temenos zei:Zou je het elke dag gebruiken? Stel dat MDMA absoluut geen negatieve werkingen heeft en zelfs gezond voor je is, en de magie van de eerste keer er elke keer is, en het 1 euro per 20 pillen kost, of gratis afhaalbaar bij de apotheek, zou je het elke dag gebruiken? Waarom wel/niet?

Olds and Milner (1954)The rat was placed in a large box with corners labeled A, B, C, and D and was allowed to explore freely. But, whenever the rat went to corner A, the experimenter pressed a button to deliver a brief, mild electrical shock through the implanted electrodes. After a few jolts, the rat kept returning to corner A and finally fell asleep in a different location. The next day, however, the rat seemed even more interested in corner A. Olds and Milner were excited: they believed that they has found a brain region that, when stimulated, provoked curiosity. However, further experiments on this same rat soon proved that not to be the case. By this time, the rat had a acquired a habit of returning often to corner A to be stimulated. The experimenters then tried to coax the rat away from corner A: they would give a shock every time the rat made a step in the direction of corner B. This worked all too well—within 5 minutes, the rat was in corner B. Further investigation revealed that this rat could be directed to any location within the box with well-timed brain shocks—brief ones to guide the rat to the target location and more sustained ones once there.
Many years earlier, the psychologist B.F. Skinner had devised the operant conditioning chamber or “Skinner Box” in which a lever press by an animal triggered either a reinforcing stimulus such as delivery of food or water, or a punishing stimulus like a painful footshock. Olds and Milner soon adapted the chamber so that a lever press would deliver direct brain stimulation through the implanted electrodes. What resulted was perhaps the most dramatic experiment in the history of behavioral neuroscience—rats would press the lever as many as 7,000 times per hour to stimulate their brains. They weren’t stimulating a “curiosity center” at all-- this was a reward circuit, the activation of which was much more powerful than any natural stimulus. A series of amazing experiments revealed that rats preferred reward circuit stimulation to food (even when they were hungry) and water (even when they were thirsty). Self-stimulating male rats would ignore a female in heat and would repeatedly cross footshock-delivering flood grids to reach the lever. Female rats would abandon their newborn nursing pups to continually press the lever. Some rats would self-stimulate 2,000 times per hour for 24 hours, to the exclusion of all other activities. They had to be unhooked from the apparatus to prevent starvation!
