Introduction to Psychology

Universidad de Toronto

4.9 (2,436 calificaciones) | 200K estudiantes inscritos

This course will highlight the most interesting experiments within the field of psychology, discussing the implications of those studies for our understanding of the human mind and human behavior. We will explore the brain and some of the cognitive abilities it supports like memory, learning, attention, perception and consciousness. We will examine human development - both in terms of growing up and growing old - and will discuss the manner in which the behavior of others affect our own thoughts and behavior. Finally we will discuss various forms of mental illness and the treatments that are used to help those who suffer from them. The fact of the matter is that humans routinely do amazing things without appreciating how interesting they are. However, we are also routinely influenced by people and events without always being aware of those influences. By the end of this course you will have gained a much better understanding and appreciation of who you are and how you work. And I can guarantee you that you'll learn things that you'll be telling your friends and family about, things that will fundamentally change the way you think of yourself and others. How can you resist that?!

Memory

This topic is Memory, and it's a big topic, and one I know a fair amount about. It was hard to figure out what to present and what to leave out. I tried to include some of the most interesting stuff. I hope you agree. After this section you'll be able to define and summarize topics such as False Memory and Amnesia.

Transcripción

Okay, so now we're going to continue where we left off by giving you this

really good sense of reconstructive memory.

And some of the errors that it can cause. let's do it.

Okay, so, Week 5, Lecture 4, remembering what wasn't.

I'll explain that in just a moment. This is going to be a little quick one.

It's mostly going, the purpose of this is to have you actually feel memory and some

of the areas that can cause. and so, we're going to start right away

with a memory test. So, I gave you that list of words to

remember at the end of last lecture. Here's a new list of words.

I want you to answer two questions for each of these words.

and so if you have a sheet of paper or something like that, I would ask that you

actually, write down your answers for these questions.

For each word I would like you to answer first, was this word one of the ones I

asked you to remember, yes or no? Then on a 10 point scale how sure are

you? Are you sure that this was on the list or

not? Even with a no I'm sure it was not, I'm

sure it was. So take a moment and do that for these

words. Don't mind me, I'm just hanging.

Okay if you're not done pause the video, but I'm going to carry on.

So, pause as long as you need to do that and then continue on.

All right, so, how good is your memory? The words in green were on the list.

So hopefully for each of those, you said yes, it was on the list and well how sure

were you? So what you should do is take those ten

sure numbers. Sorry those ten, those four.

The four numbers for those three, write them down.

And, and if you want take an average of them.

Add them up and divide by four. See what you're average confidence was.

Now the black words were not on the list. and they were really different from the

words on the list, I'll explain what that means in a moment.

but they were not on the list. So hopefully for most of those you said,

No. And you can look at your confidence for

those if you'd like. But the really interesting ones are the

ones in red. These items were not on the list.

So, one question is, for how many of these did you say yes?

And my expectation is that at least for one of these three you said yes.

If that's true, then look at that one that you said yes to.

And look at how confident you were. Is it possible that you were just as

confident as, for that one as you were for the ones in green, okay?

What's going on here? So I'm hoping at least for some of you,

you did say yes, and you were actually pretty confident.

And you were wrong, those words were not on the list.

How can you be remembering something that never occurred.

Fascinating, here was the list, okay? And the green I'm showing you the words

that were just included on the previous test.

Let's, let's go back for a second, and look at this word, thief.

Thief was not on the list, but steal, rob, crime, robber, cop, and gun were all

on the list. These are all words related to thievery.

they are all what's called strong semantic associates of the word thief.

They have a very similar meaning. So, even though thief was not actually

presented, the claim is it was kind of there.

Represented all these items that were related to thievery, and that, in your

brain, when you're trying to reconstruct that memory.

That, that concept of thief could be very active, enough to make you believe it was

actually prese, presented in the list. Over here, the critical word they were

all related to was anger, fear, emotion, wrath, temper, rage, calm is kind of the

opposite. But again these all kind of imply an

anger kind of emotion for lack of a better word.

And so a lot of people if you present a bunch of words related to anger, but not

anger, they will think anger was on the list.

It would fit right? It's kind of light, yeah.

And these ones are all related to the word fruit.

So again, the claim is by cleverly setting up these words, you can actually

make people remember things that were never presented.

And not only do they remember those things, but their confidence in the

memory is very high. So, sometimes we remember things that

never occurred with high confidence. Now, in the real world, you've run into

this. You, you've had an argument with a

friend, or a spouse, about something silly usually.

maybe you'll say something like, what did you think of the green paint that that

guy had on his wall when we were visiting last week.

And the other person might say, green, it wasn't green, it was red.

And you thought it was green, no it was red.

So now you have two people arguing about a memory of some of that.

Both extremely sure that they're correct, and obviously they cannot both be

correct. So at least one, if not both of those

people, is highly confident about something that didn't occur.

That's memory, okay? The reconstruction can produce a memory

that, that is false. And we can be very confident in it,

that's what makes memory simultaneously both so, both so fascinating, but also, a

little scary. Again, when it's used in things like

legal context to put somebody in jail. So it's fascinating.

a nice little demo. Okay., so a quick little lecture.

Okay, I just wanted you to feel that false memory, and I wanted to hopefully

produce a false memory in you. But here's some really great videos.

I, I went a little shorter on the lecture, because I really want you to

check out some of these. Loftus again talking about false

memories. Here's a, a video that, that goes into a

little bit more detail about how these false memories can be created.

And this last one, check this out, because it's really poignant.

there's, there was a time when a lot of people who had psychological issues of

some sort, we go to therapy. And the therapist would explore this

issues with them. And it was almost like a false memory

paradigm. They, the therapist might think maybe

this person was abused as a child. So they wouldn't actually say that,

because in therapy if you directly challenge somebody's traumatic memory

they often get defensive about it. So instead you talk around it, you know,

kind of like we never said the word thief.

But we said everything related to it and sometimes people in these therapeutic

situations have what's called a recovered memory.

They suddenly remember some, some very traumatic experiences like being sexually

abused as a child. which is already scary, but then

sometimes they will charge people, say uncle or something that did this.

And then subsequently find that the memory that they recovered was in fact

false. So, you know, it's one thing to falsely

remember a word. It's something else to falsely remember

sexual abuse. But there seems to be a lot of evidence

that even this level of memory can be false at times.

And so this an example one, one example, my lie, a true story of false memory, of

somebody recounting. An author recounting a situation where

she falsely accused a family member. of horrific things based on what she

later found to be a false memory. So a really poignant thing to check out

and, and to give you a sense of how big this can be.

here's the actual lists that, that I use to create those words.

So if you want to try this with your friends.

Plant some false memories just to show them it can.

And take what you've learned into the real world.

That's cool, this is a website where you can actually try some more experiments of

this sort. You can go through and do, and, and, do

them. You may need, Java installed or something

like that to make it work. but check it out if you want to

experiment more with your own memory or somebody else's, there's a good place to

do it, good tool to do it with. Alright, cool.

So, now you have the idea of how that reconstructive memory process works.

and so now in the last half of this week, we're going to talk about a number of

other issues related to memory. all stuff that's really cool, you'll find

fascinating, and I look forward to telling you about it.

Have a good night. Bye-bye.
