1
Sometimes people want to say, no, we definitely don't experience reality the way that it actually is.
2
And some people want to say, yes, we do.
3
Philosophers have been arguing about this for like as long as philosophy has existed.
4
The question of does your experience match reality or are you really experiencing reality in its stark objective truth?
5
And the answer is simply, not exactly.
6
Reality for us is what we can sense with our sensory surfaces
7
and what we can make sense of with the signals in our brain.
8
The signals in our brain are as necessary for our experience of reality as the sensory signals that come from the world.
9
So I'm going to use a metaphor to describe how the brain works.
10
It goes something like this.
11
Your brain, my brain, everybody's brain, is trapped in its own dark, silent box called your skull.
12
and the brain has no knowledge of what is going on around it in the world or in the body, right?
13
Because it's in this skull and it's receiving sensory signals from the sensory surfaces of your body.
14
These signals are the outcomes of some changes in the world or in the body.
15
But the brain doesn't know what the changes are.
16
It's receiving the outcomes.
17
And that is what philosophers and scientists call the reverse inference problem.
18
You start with an outcome and you have to guess at the cause.
19
For example, if you hear a loud bang, It could be a car backfiring, a door slamming.
20
It could be a gunshot.
21
Your brain doesn't know what the causes are.
22
It only knows the effect.
23
And so it has to guess.
24
And the guess is important, right, because you would do different things if it's a gunshot versus if it's a windy day that slammed a door.
25
And luckily, it has one other source of information, and that is your past experience.
26
The really cool thing about this, if that wasn't cool enough, is that it's actually doing it predictively.
27
Sometimes scientists talk about this as the brain running a model of the world.
28
But the brain is not running a model of the world.
29
The brain is running a model of its body.
30
And it's doing it in this really interesting way.
31
In psychology, a group of instances which are similar is called a category.
32
In essence, what your brain is doing, when it's making a prediction, it's creating a category of instances from the past
33
which are similar in some way to the present in order to predict what's going to happen next, what the brain has to do next and what your experience will be next.
34
And so when a human brain is creating a category,
35
you have to ask, what features of similarity is it using?
36
Is it these sensory and motor features?
37
An apple is round, an apple is hard and crunchy, or is it these abstract features,
38
abstract multimodal summaries of patterns of features.
39
I could take a bunch of apples and I could say, well, these are good for baking and these are not good for baking.
40
And these patterns, this summary, only exists in your brain.
41
Because our brains are structured to construct categories
42
based on the function of things rather than what they look like or taste like or smell like,
43
humans can create something called social reality
44
which is where we collectively impose a function on objects that the objects don't have by virtue of their physical nature.
45
So a really good example of this is money, little pieces of paper.
46
We all agree that these little pieces of paper have a function of value.
47
And it turns out that many things that we think of as being part of reality are actually like this.
48
We can draw lines in the sand and create the borders of countries, which creates categories of people called immigrants and citizens.
49
We can create governments, because we all agree that certain actions, like making little tick marks,
50
has a meaning to elect someone into a position that has certain powers.
51
It's a form of social reality.
52
In our lab, we work on the hypothesis that many psychological categories are forms of social reality.
53
We impose a meaning on a scowling face that it did not evolve to have.
54
But because we all agree that it has that meaning or that function in a particular culture, then it does.
55
To say that your brain resides in a dark, silent box doesn't mean that you are trapped in that box.
56
Your brain has this wonderful capacity to take bits
57
and pieces of past experience and create something completely new that you've never experienced before.
58
We call it imagination.
59
That's a double-edged sword, right?
60
Because our brains are so good at imagining and creating predictions that are not yoked to our immediate surroundings,
61
sometimes we have a lot of trouble staying in the present.
62
You have to practice your ability to control how much you want to be constrained
63
by what's going on outside that box and how much you want to be free of it.

- Stemhebbende eindmedeklinker — /b/, /d/, /g/, /z/, /v/ niet verscherpen: reside /ɹɪˈzaɪd/, surroundings /səˈɹaʊndɪŋz/, evolve /ɪˈvɑlv/
- /æ/ — opener dan de Nederlandse “e”: slam /ˈslæm/, backfire /bækˈfaɪə(ɹ)/, similarity /ˌsɪm.ɪˈlæɹ.ɪ.ti/

Wat is de Shadowing-techniek?
Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
