00:00:01,260 --> 00:00:02,760
- [Instructor] Imagine
organizing your room

2
00:00:02,760 --> 00:00:04,710
without any shelves or drawers.

3
00:00:04,710 --> 00:00:06,360
Sounds chaotic, right?

4
00:00:06,360 --> 00:00:09,120
That's kind of how your brain
would work without schemas.

5
00:00:09,120 --> 00:00:12,510
It's personal filing system
for understanding the world.

6
00:00:12,510 --> 00:00:14,730
What exactly is a schema?

7
00:00:14,730 --> 00:00:16,590
Think of it like a mental template,

8
00:00:16,590 --> 00:00:19,650
a prebuilt picture of things
you've encountered before.

9
00:00:19,650 --> 00:00:22,740
When you see a dog, your
dog schema kicks in,

10
00:00:22,740 --> 00:00:24,180
filling in the blanks,

11
00:00:24,180 --> 00:00:27,390
furry, wags its tail, and barks.

12
00:00:27,390 --> 00:00:30,300
Schemas help you make sense
of new information quickly

13
00:00:30,300 --> 00:00:33,960
and efficiently without
starting from scratch each time.

14
00:00:33,960 --> 00:00:36,000
Why are schemas so useful?

15
00:00:36,000 --> 00:00:38,940
Imagine seeing a new
restaurant for the first time.

16
00:00:38,940 --> 00:00:41,790
You wouldn't need to analyze
every detail like the tables

17
00:00:41,790 --> 00:00:44,520
and chairs to know it's a restaurant.

18
00:00:44,520 --> 00:00:47,760
Your restaurant schema would
tell you, they serve food,

19
00:00:47,760 --> 00:00:50,910
you order from a menu,
and you pay after eating.

20
00:00:50,910 --> 00:00:53,520
Schemas save you time and mental energy,

21
00:00:53,520 --> 00:00:55,440
letting you focus on the unique aspects

22
00:00:55,440 --> 00:00:56,970
of the new experience.

23
00:00:56,970 --> 00:00:58,950
Different types of schemas.

24
00:00:58,950 --> 00:01:00,630
Think of your brain's filing system

25
00:01:00,630 --> 00:01:03,450
as having separate folders
for different things.

26
00:01:03,450 --> 00:01:07,770
You have schemas for
objects: cars, houses, food,

27
00:01:07,770 --> 00:01:09,510
anything you can interact with.

28
00:01:09,510 --> 00:01:13,650
Events: going to school, playing
sports, attending a party.

29
00:01:13,650 --> 00:01:15,840
What happens in how it unfolds?

30
00:01:15,840 --> 00:01:18,240
People: teachers, friends, family,

31
00:01:18,240 --> 00:01:19,650
their roles, personalities,

32
00:01:19,650 --> 00:01:21,300
and how you interact with them.

33
00:01:21,300 --> 00:01:23,550
Roles: doctor, athlete, student,

34
00:01:23,550 --> 00:01:25,830
what someone does and how they behave.

35
00:01:25,830 --> 00:01:29,490
Self: your own likes, dislikes,
skills and experiences.

36
00:01:29,490 --> 00:01:31,380
Your unique place in the world.

37
00:01:31,380 --> 00:01:33,210
How do schemas develop?

38
00:01:33,210 --> 00:01:34,980
Think back to when you were little.

39
00:01:34,980 --> 00:01:36,180
Your first dog schema

40
00:01:36,180 --> 00:01:38,040
might have been based on seeing pictures

41
00:01:38,040 --> 00:01:39,930
or meeting one friendly pup.

42
00:01:39,930 --> 00:01:43,140
As you encounter more dogs,
your schema gets updated.

43
00:01:43,140 --> 00:01:44,700
You learn that some bark loudly,

44
00:01:44,700 --> 00:01:47,610
some are small, and some chase squirrels.

45
00:01:47,610 --> 00:01:50,640
Schemas constantly evolve
with new experiences.

46
00:01:50,640 --> 00:01:52,290
The ups and downs of schemas.

47
00:01:52,290 --> 00:01:53,760
Schemas are powerful,

48
00:01:53,760 --> 00:01:56,970
but they can sometimes lead
to shortcuts and biases.

49
00:01:56,970 --> 00:01:58,740
You might have a teacher schema

50
00:01:58,740 --> 00:02:00,420
that expects them to be strict,

51
00:02:00,420 --> 00:02:01,590
which could make you nervous

52
00:02:01,590 --> 00:02:03,720
around a more laid back instructor.

53
00:02:03,720 --> 00:02:06,030
This is where critical thinking comes in,

54
00:02:06,030 --> 00:02:07,890
questioning your initial assumptions

55
00:02:07,890 --> 00:02:10,410
and being open to new information.

56
00:02:10,410 --> 00:02:12,810
Remember, schemas are your brain's way

57
00:02:12,810 --> 00:02:14,730
of organizing the world.

58
00:02:14,730 --> 00:02:18,000
They help you understand new
things quickly and efficiently.

59
00:02:18,000 --> 00:02:21,330
Different types of schemas
exist for different things.

60
00:02:21,330 --> 00:02:24,480
They develop and change
based on your experiences.

61
00:02:24,480 --> 00:02:27,723
Be aware of potential biases
and use critical thinking.
