Under-developed "rational" brain before 25 years of age is a funny meme. Most readers should stop here.) Difference in spending between cach and credit card attributed to "layering" is another meme. Correlation is not causation. The effect is, probably, based on the fact that there almost always bigger sum of money on the card than in cash in a pocket, so, the loss seemed less significant. As for monetization strategies, it seems that nothing can beat "status items" (same as in so-called real life) such as "armors", "cloches" and all those "things" one could display and compare with others. But so many papers..)

  Because one cannot reliable test such assumptions due to multiple very different factors in play (multiple causation). "Prefrontal cortex as the seat of rational brain" is just a meme - a huge over-simplification, as rationality itself. It is more sane to talk about control of emotions - ability of an activity in one region of the brain interfere with, or tame other activity in a different region, which requires "training" of appropriate "networks" via repeated exposure to certain behavioral patterns (experience). This could be attributed to ageing, that adults just had more practice of self-control, but it will be just another meme, because each process of maturation is unique, due to almost intractable number of factors involved. Even cross-culturally, my beat is that if some could compare group of "typical US students" with a group of Asian "Buddhist monks" of the same age, there will be significant differences in prefrontal cortex activities.) Read some Marvin Minsky for great good.)
