00:01
Recalled memories are rarely complete but
instead are constructs of stored info.
00:05
This is a very important concept.
00:09
And what I’m saying
here is, it’s very rare
that you remember every single
aspect of either a situation
or a conversation or an episode.
00:19
So if I ask you to recall the
first date with your wife,
you’re going to get a couple
of really good pieces, right?
You might remember
what you wore.
00:28
You kind of might remember
where you went for dinner.
00:31
You might even remember --
you might think you
remember what you ordered.
00:36
Now, when you’re recalling the story,
and this has happened to people,
you say, “Oh, can you
tell me how you two met?”
And you’re like, “Yeah.
Well, let me tell you.
00:43
Well, it was a Sunday.
00:44
It was sunny.
00:46
And we went for a walk.
00:47
I remember I was
wearing my blue pants.
00:49
We were holding hands.
It was a great day.”
And they go on and they explain all
these detail and you’re thinking
“How does this person
remember everything?”
Well, the truth is, they
actually don’t and they’ve built
a construct and they’re
filling in some of the gaps.
01:01
And the gaps can be filled in with
representative information from a schema.
01:05
So, it’s stuff that they’re going
to fill in to fill the gaps
in order to complete the story, and
that’s not that they’re filling in with
stuff that aligns quite
well with the story
and the point or the schema of
what that story is trying to do.
01:18
There’s also the situation where
the gaps are actually inaccurate
but they align well with what
the end goal of the story is
and they align well with what
that person is trying to impart.
01:30
Okay?
Now, a schema
is a mental blueprint containing common
aspects of some part of our world.
01:36
We build schemas for so
many different things.
01:39
So for example, if I say to you,
“Describe your second grade classroom.”
Or, “Describe your childhood bedroom.”
I think you’ll get a couple
of key features, right?
So yeah, I had my bed. I had a desk.
I had a Michael Jackson poster.
01:53
I had this and I had that and I had a nice,
big teddy bear that I cuddled every night.
01:57
Those you get, but
are you going to get
every little aspect?
Probably not.
02:02
So the schema is our
representation of that room
and we have schemas for
so many different things.
02:10
Okay?
And we’ve talked about
schemas in other
modules in this course relating
to that exact concept.
02:16
So, inappropriate information
may be used when
reconstructing memories when
exposed to subtle misdirection.
02:21
We call that the
misinformation effect.
02:23
The example I’ve already
just given you.
02:26
Okay.
02:26
So here’s an example
of a schematic.
02:30
What we think, say for example, a memory
might look like if it’s being construct.
02:34
And you can see there are
lots of different components.
02:35
And I’m not going to really get into
all, all the aspects of this figure.
02:38
That’s not the
important point here.
02:40
What I want you to get is,
visually, when you look at this,
you see all the
little components.
02:44
You can see how you
can have gaps.
02:46
And when you’re recalling
this information,
you’re going to fill in
some of those gaps with
information that you feel
will help tell your story.
02:56
Memory construction and
source monitoring.
02:58
Now, repeated recall of
nonexistent actions and events
or misinformation can actually
lead to false memories.
03:06
You’ve heard this on the
witness stand all the time.
03:09
You hear something that’s
false enough times
and it actually in your
mind becomes true.
03:15
And you can do this
with memories.
03:17
You can tell somebody
something so many times
even though it’s a lie
or it’s a non-truth.
03:24
And it actually ends up becoming
in your mind an encoded memory.
03:29
So, you might say, “Oh yeah, this
girl, she asked me out in high school
and she used to ask me at all the time.
She really liked me a lot.”
And you may have said
that at the time
to your friends so that you fit
in because they were all dating
and you would have
to tell stories
saying, “Well, yeah, I got asked out to.
Yeah, I got asked all the time.”
And you keep saying this,
you keep saying this.
03:48
And over the years as you
become an adult, in your mind,
you actually thought, “High school wasn’t
bad. I got asked out quite a few times.”
In reality, you never
got asked out.
03:56
You never had a date and you
went to prom with your mother.
03:59
So,
in your mind though, you’re
playing back the fact that you
actually did have a lot of dates
and this is a false memory.
04:05
Now, familiarity and
emotional content can make
these indistinguishable
from actual memories.
04:10
So the more
convoluted, more familiar, the more
emotionally attached you are and how much
emotional content that’s
there in the story,
it actually becomes very
difficult to tease that out
and say, you know, this
is real and this is fake.
04:23
Source monitoring is
understanding where the content
of the original encoded
memory comes from.
04:28
And so, again, this is working
backwards in saying, okay,
this nugget of your memory
or story is sort of true
and this is where it comes
from and all the rest,
are you filling in gaps or is
context that you’ve layered in.
04:40
Where did the original concept or
the original memory come from?
Source monitoring.
04:47
Now, errors or unknown
source monitoring can occur.
04:51
So there’s kind of an example that we’ll
have as a transfer of dream content.
04:56
And again, we’ve probably done this
before too where you have a dream,
something happen in the dream.
05:01
In the dream, you think
you went to Mexico.
05:06
And when you’re in Mexico,
you swam with the dolphins.
05:10
Now, this dream content
actually gets transferred
to the point where you think that, “Hey, no,
I think I’ve swam with dolphins before.”
And people might say,
“Man, are you dreaming?”
And you’re like, “Well, actually,
maybe I was. I don’t know.
05:24
I don’t know if that was true
or if that was a dream.”
So, you know, where
do I know you from?
Here’s an example of, “Well, I know
you from somewhere, well maybe not.”
Maybe it was a dream.
05:36
Maybe you saw me in a picture.
05:37
Nowadays with social media, this actually
happened to me very recently where
somebody came up to me and
said, “Hey, I know you.”
And I said, “Actually, I
don’t think we ever met.”
And through a discussion
we started talking.
05:48
We realized that this person knows
a mutual friend that I have
and my friend was tagged in a
picture on Facebook with me
and so this person ended up seeing it saw
me and now thought that they knew me.
06:02
I had never met them. I don’t
know who they are at all.
06:05
He comes up and says, “Hey, I know
you.” I said, “I don’t think so.”
And what they’ve done is they’ve
transferred some of that content
into their memory as an actual
memory but in reality, it’s not.
