I can't seem to create a new thread in this forum right now, but I'd like to mention something related to this experiment. As the OP states, Stanford psychologist Philip Zimbardo had his own TED talk,
The demise of guys?
It's only five minutes long but his main point is arguing that today's boys and young men have become less masculine and more addicted to virtual pursuits. Porn, video games, the internet are all mentioned. What I feel about this is that all of this comes down to novelty. Electronic media allows almost instantaneous return of information and entertainment. We can be continuously entertained and the reward circuitry of our brains triggered.
So I'm wondering, can this same sort of experiment be done to other media? Certainly there would be big differences- I think the main issue about porn is that it leads to orgasm, that the sex hormones and chemicals involved are very powerful. Internet use or gaming... not so much. But the same idea behind novelty is there. I also think to bring up earlier points, modern day pornography is instantaneously-acquired, unlike Playboys and so forth. Same idea holds for non-sexual novelty from the internet. (I don't think the same issue applies to video games, unless they're like online games that continuously generate new content.)
So how about some sort of challenge to moderate internet use? How about something that targets other sources of modern day first-world novelty?
