So one part is the parietal cortex Dialogue: 0,0:08:40.52,0:08:44.24,Default,,0000,0000,0000,,which is very well known to control the orientation of attention. Dialogue: 0,0:08:44.24,0:08:46.67,Default,,0000,0000,0000,,The other one is the frontal lobe, which controls Dialogue: 0,0:08:46.67,0:08:49.38,Default,,0000,0000,0000,,how we sustain attention, and another one Dialogue: 0,0:08:49.38,0:08:51.95,Default,,0000,0000,0000,,is the anterior cingulate, which controls how we allocate Dialogue: 0,0:08:51.95,0:08:55.25,Default,,0000,0000,0000,,and regulate attention and resolve conflict.

Dialogue: 0,0:11:29.47,0:11:33.76,Default,,0000,0000,0000,,The other lesson is that general wisdom carries no weight. Dialogue: 0,0:11:33.76,0:11:36.81,Default,,0000,0000,0000,,I showed that to you already, like we looked at the fact that Dialogue: 0,0:11:36.81,0:11:39.26,Default,,0000,0000,0000,,despite a lot of screen time, those action gamers Dialogue: 0,0:11:39.26,0:11:43.27,Default,,0000,0000,0000,,have a lot of very good vision, etc. Dialogue: 0,0:11:43.27,0:11:46.58,Default,,0000,0000,0000,,Here, what was really striking is that these undergraduates Dialogue: 0,0:11:46.58,0:11:49.83,Default,,0000,0000,0000,,that actually report engaging in a lot of high Dialogue: 0,0:11:49.83,0:11:54.80,Default,,0000,0000,0000,,multimedia-tasking are convinced they aced the test.

But when consumed Dialogue: 0,0:12:28.36,0:12:31.84,Default,,0000,0000,0000,,in reasonable doses, and at the right age, Dialogue: 0,0:12:31.84,0:12:35.11,Default,,0000,0000,0000,,wine can be very good for health.

What they showed is that, initially, Dialogue: 0,0:15:17.91,0:15:20.11,Default,,0000,0000,0000,,you know, subjects perform where they are expected Dialogue: 0,0:15:20.11,0:15:25.32,Default,,0000,0000,0000,,to perform given their age. After two weeks of training Dialogue: 0,0:15:25.32,0:15:29.18,Default,,0000,0000,0000,,on action video games, they actually perform better, Dialogue: 0,0:15:29.18,0:15:34.53,Default,,0000,0000,0000,,and the improvement is still there five months after Dialogue: 0,0:15:34.53,0:15:37.40,Default,,0000,0000,0000,,having done the training. That's really, really important. Dialogue: 0,0:15:37.40,0:15:39.88,Default,,0000,0000,0000,,Why? Because I told you we want to use these games Dialogue: 0,0:15:39.88,0:15:43.08,Default,,0000,0000,0000,,for education or for rehabilitation. We need to have effects Dialogue: 0,0:15:43.08,0:15:46.02,Default,,0000,0000,0000,,that are going to be long-lasting. Dialogue: 0,0:15:46.02,0:15:48.87,Default,,0000,0000,0000,,Now, at this point, a number of you are probably wondering Dialogue: 0,0:15:48.87,0:15:52.50,Default,,0000,0000,0000,,well, what are you waiting for, to put on the market Dialogue: 0,0:15:52.50,0:15:55.06,Default,,0000,0000,0000,,a game that would be good for the attention Dialogue: 0,0:15:55.06,0:15:58.58,Default,,0000,0000,0000,,of my grandmother and that she would actually enjoy, Dialogue: 0,0:15:58.58,0:16:01.16,Default,,0000,0000,0000,,or a game that would be great to rehabilitate the vision Dialogue: 0,0:16:01.16,0:16:04.97,Default,,0000,0000,0000,,of my grandson who has amblyopia, for example? Dialogue: 0,0:16:04.97,0:16:09.45,Default,,0000,0000,0000,,Well, we're working on it, but here is a challenge. Dialogue: 0,0:16:09.45,0:16:11.36,Default,,0000,0000,0000,,There are brain scientists like me that are beginning Dialogue: 0,0:16:11.36,0:16:14.62,Default,,0000,0000,0000,,to understand what are the good ingredients in games Dialogue: 0,0:16:14.62,0:16:17.72,Default,,0000,0000,0000,,to promote positive effects, and that's what I'm going Dialogue: 0,0:16:17.72,0:16:21.29,Default,,0000,0000,0000,,to call the broccoli side of the equation. Dialogue: 0,0:16:21.29,0:16:25.03,Default,,0000,0000,0000,,There is an entertainment software industry Dialogue: 0,0:16:25.03,0:16:28.50,Default,,0000,0000,0000,,which is extremely deft at coming up with Dialogue: 0,0:16:28.50,0:16:32.65,Default,,0000,0000,0000,,appealing products that you can't resist. Dialogue: 0,0:16:32.65,0:16:36.17,Default,,0000,0000,0000,,That's the chocolate side of the equation. Dialogue: 0,0:16:36.17,0:16:39.20,Default,,0000,0000,0000,,The issue is we need to put the two together, Dialogue: 0,0:16:39.20,0:16:41.45,Default,,0000,0000,0000,,and it's a little bit like with food.

(Laughter) And you probably have had Dialogue: 0,0:16:47.35,0:16:49.69,Default,,0000,0000,0000,,that feeling, right, picking up an education game Dialogue: 0,0:16:49.69,0:16:53.08,Default,,0000,0000,0000,,and sort of feeling, hmm, you know, it's not really fun, Dialogue: 0,0:16:53.08,0:16:55.50,Default,,0000,0000,0000,,it's not really engaging. So what we need Dialogue: 0,0:16:55.50,0:16:58.85,Default,,0000,0000,0000,,is really a new brand of chocolate, a brand of chocolate Dialogue: 0,0:16:58.85,0:17:02.86,Default,,0000,0000,0000,,that is irresistible, that you really want to play, Dialogue: 0,0:17:02.86,0:17:05.84,Default,,0000,0000,0000,,but that has all the ingredients, the good ingredients Dialogue: 0,0:17:05.84,0:17:09.07,Default,,0000,0000,0000,,that are extracted from the broccoli that you can't recognize Dialogue: 0,0:17:09.07,0:17:11.91,Default,,0000,0000,0000,,but are still working on your brains. And we're working on it, Dialogue: 0,0:17:11.91,0:17:16.38,Default,,0000,0000,0000,,but it takes brain scientists to come and to get together, Dialogue: 0,0:17:16.38,0:17:19.35,Default,,0000,0000,0000,,people that work in the entertainment software industry, Dialogue: 0,0:17:19.35,0:17:22.09,Default,,0000,0000,0000,,and publishers, so these are not people that usually Dialogue: 0,0:17:22.09,0:17:24.42,Default,,0000,0000,0000,,meet every day, but it's actually doable, Dialogue: 0,0:17:24.42,0:17:27.07,Default,,0000,0000,0000,,and we are on the right track.
