0:00:03.560,0:00:06.569
Inter what now? Don't be put off by the

0:00:06.569,0:00:09.269
fancy name. All this really means is that

0:00:09.269,0:00:11.250
if you study a couple of things, at once

0:00:11.250,0:00:14.490
you'll learn more. Let me explain,

0:00:14.490,0:00:16.650
imagine you're learning geography and

0:00:16.650,0:00:20.250
you have three topics: rivers, droughts,

0:00:20.250,0:00:22.980
and pollution. You might think that it

0:00:22.980,0:00:24.689
would be best to study everything in

0:00:24.689,0:00:26.849
rivers, making sure you know it really

0:00:26.849,0:00:29.699
well before moving on. It just makes

0:00:29.699,0:00:32.308
sense. Better to focus on one topic and

0:00:32.308,0:00:34.559
get really good at it, then tackle the

0:00:34.559,0:00:39.390
next topic. But, it turns out this is

0:00:39.390,0:00:42.059
wrong. Remember when we talked about the

0:00:42.059,0:00:44.879
pathways in the brain, you want to build

0:00:44.879,0:00:46.950
the strongest path possible so that it

0:00:46.950,0:00:50.370
lasts as long as possible. It feels like

0:00:50.370,0:00:52.379
going over it lots in one go will be

0:00:52.379,0:00:54.629
the best way to do this, but actually

0:00:54.629,0:00:58.430
research shows that this isn't the case.

0:00:58.430,0:01:01.410
In order to build a good path you have

0:01:01.410,0:01:04.739
to make the most effort. In the brain,

0:01:04.739,0:01:07.920
effort means working hard. If you study

0:01:07.920,0:01:10.500
rivers, droughts, and earthquakes all at

0:01:10.500,0:01:12.840
the same time, your brain has to jump

0:01:12.840,0:01:16.259
between three different topics. That's a

0:01:16.259,0:01:18.570
lot harder than just staying with one, so

0:01:18.570,0:01:20.759
your brain puts in a lot more effort and

0:01:20.759,0:01:22.799
you will learn the three topics much

0:01:22.799,0:01:23.479
better.

0:01:23.479,0:01:26.640
Fair warning, it will feel more difficult

0:01:26.640,0:01:29.549
than studying one topic at a time. But

0:01:29.549,0:01:31.500
know that all that effort is growing

0:01:31.500,0:01:33.329
your brain and your learning will

0:01:33.329,0:01:36.320
jumpstart.
