WEBVTT 00:00:03.560 --> 00:00:06.569 Inter what now? Don't be put off by the 00:00:06.569 --> 00:00:09.269 fancy name. All this really means is that 00:00:09.269 --> 00:00:11.250 if you study a couple of things, at once 00:00:11.250 --> 00:00:14.490 you'll learn more. Let me explain, 00:00:14.490 --> 00:00:16.650 imagine you're learning geography and 00:00:16.650 --> 00:00:20.250 you have three topics: rivers, droughts, 00:00:20.250 --> 00:00:22.980 and pollution. You might think that it 00:00:22.980 --> 00:00:24.689 would be best to study everything in 00:00:24.689 --> 00:00:26.849 rivers, making sure you know it really 00:00:26.849 --> 00:00:29.699 well before moving on. It just makes 00:00:29.699 --> 00:00:32.308 sense. Better to focus on one topic and 00:00:32.308 --> 00:00:34.559 get really good at it, then tackle the 00:00:34.559 --> 00:00:39.390 next topic. But, it turns out this is 00:00:39.390 --> 00:00:42.059 wrong. Remember when we talked about the 00:00:42.059 --> 00:00:44.879 pathways in the brain, you want to build 00:00:44.879 --> 00:00:46.950 the strongest path possible so that it 00:00:46.950 --> 00:00:50.370 lasts as long as possible. It feels like 00:00:50.370 --> 00:00:52.379 going over it lots in one go will be 00:00:52.379 --> 00:00:54.629 the best way to do this, but actually 00:00:54.629 --> 00:00:58.430 research shows that this isn't the case. 00:00:58.430 --> 00:01:01.410 In order to build a good path you have 00:01:01.410 --> 00:01:04.739 to make the most effort. In the brain, 00:01:04.739 --> 00:01:07.920 effort means working hard. If you study 00:01:07.920 --> 00:01:10.500 rivers, droughts, and earthquakes all at 00:01:10.500 --> 00:01:12.840 the same time, your brain has to jump 00:01:12.840 --> 00:01:16.259 between three different topics. That's a 00:01:16.259 --> 00:01:18.570 lot harder than just staying with one, so 00:01:18.570 --> 00:01:20.759 your brain puts in a lot more effort and 00:01:20.759 --> 00:01:22.799 you will learn the three topics much 00:01:22.799 --> 00:01:23.479 better. 00:01:23.479 --> 00:01:26.640 Fair warning, it will feel more difficult 00:01:26.640 --> 00:01:29.549 than studying one topic at a time. But 00:01:29.549 --> 00:01:31.500 know that all that effort is growing 00:01:31.500 --> 00:01:33.329 your brain and your learning will 00:01:33.329 --> 00:01:36.320 jumpstart.
