Shadowing Practice: How Memory can be manipulated, with Elizabeth Loftus, PhD | Speaking of Psychology - Learn English Speaking with Video

Hello and welcome to Speaking of Psychology, a podcast produced by the American Psychological Association.

I'm your host, Kaitlin Luna.

I'm joined by Dr. Elizabeth Loftus, a distinguished professor at the University of California, Irvine.

Dr. Loftus is well known for her research on human memory, notably false memories.

Dr. Loftus has been honored by APA's Review of General Psychology

as one of the 100 most eminent psychologists of the 20th century.

Welcome Dr. Loftus.

Thank you.

It's wonderful to have you here today.

My pleasure.

So your research tells us something I would think is unsettling about our minds, that our memories aren't set in stone, that they're basically subject to manipulation.

So can you Can you explain that a bit more?

One of the things that I

and other people who do similar work have shown is that once you have an experience and you record it in memory,

it doesn't just stick there in some pristine form, you know, waiting to be played back like a recording device,

but rather new information, new ideas,

new thoughts, suggestive information, misinformation can enter people's conscious awareness and cause a contamination,

a distortion, an alteration in memory.

And that's the kind of thing that I've been studying for the past many decades.

And how can human memories be manipulated?

They can be manipulated when people talk to each other after, let's say, some crime is over that they may have both witnessed.

They can be manipulated when they are interrogated by an investigator who maybe has an agenda

or has a hypothesis about what probably happened and communicates that to the witness, even inadvertently.

People can be manipulated when they see media coverage about an event.

Let's say it's a high publicity event that is talked about a lot on television or newspapers.

In all of these cases, the opportunity is there for new information, not necessarily accurate information, to contaminate a person's memory.

And what got you interested in this work?

Oh, gosh.

I got interested in studying memory distortion many decades ago.

As a graduate student, I'd done a little bit of work on human memory.

and then once I got my PhD I wanted to do some work

that had a more immediate practical application and and

so I thought well I know something about memory

but how about looking at the memory of witnesses to accidents crimes

and other legally relevant events

so I kind of combined an interest in legal issues with some expertise in human memory and produced this line of work.

Can you take us back to the early 1990s when you talk about the memory wars?

So what was that time like and what was happening?

Oh, gee, that, well, in the 1990s and even in maybe the late 80s,

we began to see an altogether more extreme kind of memory problem.

Some patients were going into therapy, maybe they had anxiety or maybe they had an eating disorder or maybe they were depressed.

And they would end up with a therapist who said something like, well, many people I've seen with your symptoms were sexually abused as a child child

and there would begin these activities

that would lead these patients to start to think they remembered years of brutalization

that they had allegedly banished into the unconscious until this this therapy made them aware of it

and in many instances these people sued their parents

or got their former neighbors or doctors

or teachers whatever prosecuted based on these claims of repressed memory so

so the the wars were really about whether people can take

years of brutalization banish it into the unconscious be completely unaware aware

that these things happen and then reliably recover all this information later.

And that was what was so controversial and disputed.

And your work essentially refuted that, that it's not necessarily possible or maybe brought up to light that this isn't.

Well, my work actually provided an alternative explanation.

Where could these reports be coming from if this didn't happen?

So my work showed that you could plant very rich, detailed, false memories in the minds of people.

It didn't mean that repressed memories did not exist.

Repressed memories could still exist and false memories could still exist.

But there really wasn't any strong, credible scientific support for this idea of massive repression.

And yet so many families were destroyed by this, what I would say, unsupported claim.

And going off on what you just said, you were at one point sued by a woman who claimed that her mother sexually abused her.

And in this situation, you believed the mother had not done this abuse.

And you published, and you called it an expose, and it was controversial, and you were sued by this daughter.

And you talked about, in your TED talk, you talked about the disturbing trend of scientists being sued or for their work.

So can you speak a little bit about that?

And what is that, as a scientist, what does that mean?

There was a case history that was floating around in the literature published by a psychiatrist.

And it was being used as the new proof of massive repression.

The case history was anonymous, so it was Jane Doe and John Doe, Mom's Town, Dad's Town.

And at some point, I was able to identify the Doe family.

And once I found the Doe family, the name of the family, then I could get into the divorce file,

and I found all kinds of information that had been left out of this psychiatrist's account.

And I found enough information to convince me that that was a very strong likelihood that this accused mother,

oddly the mother accused of sexual abuse, was probably innocent.

And just being involved in this investigation got me in a lot of hot water.

So, yes, the adult daughter did sue me and sue my co-author

and the magazine where we published the expose and some other people.

And eventually, after years, the litigation ended.

And you won the, in 2016, you won the John Maddox Prize, which recognizes the work of scientists who promote science and evidence,

but might face difficulty in doing so or hostility.

So can you talk a little bit about that and why you believe it's important to speak out, even when it's difficult, even when you face these tough situations where you might be sued

or your name gets called out and dragged through the mod, that sort of thing?

Well, I did win the John Maddox Prize.

I'm very proud of that because it is a recognition of standing up for science

and in the face of a lot of hostility.

And the hostility came not just from a lawsuit, but other individuals who were feeling,

I guess, that their cherished beliefs were being attacked and would lash out in all kinds of unpleasant ways.

But I do think it's important because, I mean, science, you know, is that candle in the dark.

And, you know, it is the thing that's going to help make this a better world.

So, and it needs to be protected, especially in today's climate.

Can you talk about the ethical questions that have come up about your research and how you've responded?

I'll say that again.

Can you talk about the, can you speak to the ethical questions that have come up about your research and how you've responded over the years?

The ethical questions.

Well, I suppose one ethical question is whether,

what I do in my experiments is plant false memories in the minds of people in order to study the process.

Little bitty false memories and then great big ones.

So some people might think that that's not a very ethical thing to do,

but number one, everything is reviewed by the human subjects review committees at the universities.

100

Many people have done these same kinds of experiments.

101

As far as I know, there's never been an adverse effect,

102

and it has been a scientific contribution that I think has helped make the world a better place.

103

And you've spoken about the positives of planting false memories like

104

how it can be used in a positive way can you elaborate a little more on

105

that and what you're what you mean by

106

that yes um one one little twist in the false memory work uh

107

that we did is to look at the consequences of having a false memory

108

if i plan a false memory in you does it have ripple effects does it affect your later thoughts

109

or your later intentions or your later behavior and we've now shown

110

that you can plan a false memory that you got sick eating a particular food, you got sick on pickles or eggs or strawberry ice cream,

111

and you don't want to eat as much of that food.

112

We've planted false memories that you got sick drinking a vodka drink and you're not as interested in a vodka drink.

113

We've done the opposite, planted a warm fuzzy memory that you loved a healthy food,

114

asparagus, in our study, and people want to eat more asparagus.

115

So So if we can control people's nutritional selections and maybe help them live a healthier life,

116

maybe that's not a bad thing to do.

117

Is there any dangers to planting false memories?

118

Even if it is for something positive, like you're trying to eat healthier, lose weight or something like that.

119

Well, the danger, I guess the danger is that some evil,

120

nefarious people could take this mine technology and put it to some bad use.

121

Just the way we can build a nuclear bomb now and put it to some bad use.

122

Can you talk about the broad implications of your research on criminal law?

123

I think that the work that I and many other people have done on human memory,

124

eyewitness testimony, the memory of witnesses and victims to crimes, has had some impact on the legal system.

125

The scientific studies have revealed something that we might call best practices

126

that have been implemented in a number of jurisdictions so that

127

when law enforcement and many people Members of the legal system interact with people who are involved in legal cases.

128

They get the most accurate and complete information from people.

129

And we aren't wrongly convicting people of crimes they didn't do.

130

So I see some great impact there.

131

Is there anything we can do to prevent against false memories or to enhance our memories?

132

Oh, you know, if you warn people that somebody might be trying to mislead them or fool them,

133

they can momentarily protect themselves and kind of fend off the misinformation.

134

The problem is that people don't walk around in life with those warnings at the forefront of their consciousness.

135

And so we're going to need to find some other ways of getting people to protect themselves.

136

And can you enhance your memory?

137

Like can you, you know, to ensure that maybe the information you do remember is more accurate?

138

Or is it even possible?

139

There are things you can do to enhance your memory for

140

usually two simple things are just to pay better attention at the time you're experiencing something

141

or learning somebody's name at a party, for example, and then rehearsal.

142

We know the best patterns of rehearsal that are known to maximize the likelihood that people will remember the information.

143

Just as we spoke about prepping for your TED talk, you said you had it took many months to prep for memorizing a 16-minute talk.

144

So it's a lot of work to memorize something that long and to enhance your memory.

145

I mean, you know, I've been teaching for decades when I was invited to do a TED talk at TED Global.

146

And so this was going to be a talk in front of maybe a thousand people in the audience,

147

And then it would go out on the TED website and it would be translated into who knows how many languages.

148

So the exact wording was part of it.

149

And you have to memorize it.

150

And it actually took me about three months of practicing

151

and talking to the mirror and talking to trees to get it down.

152

And I used a few tricks that I'd learned as a memory scientist, like the method of loci.

153

And so I could even give you the talk right now, even though it's been five years.

154

What are some of those methods, you said?

155

I mean, it's obviously repetition and...

156

No, the method of loci involves taking a chunk of material that you want to remember and placing it in a spot,

157

let's say, in your home, and then the next chunk in another spot, and the next chunk in another spot.

158

And then you take a mental walk through your home and you see the chunks.

159

So, for example, I'd like to tell you about a case I worked on involving a man named Steve Titus.

160

Titus was a restaurant manager, and one day he was accused of a horrible crime.

161

So I remember that because I walked to my front door and there is Steve Titus, okay?

162

Tell him about Titus.

163

And then I go into my house and there's a portrait over here that my mother-in-law did when I married her son.

164

I look at, tell him about you, you know.

165

Then there's some pine cones over here.

166

That's the wrongly accused.

167

Tell him about the wrongly accused.

168

So in walking through a familiar location where you've placed chunks of what you need to remember, you can master it.

169

That's fascinating.

170

I definitely need to work on that.

171

Well, there's a fabulous book called Moonwalking with Einstein that describes this whole method.

172

It's really a great popular book.

173

That's wonderful.

174

Well, thank you so much for joining us, Dr. Loftus.

175

I really appreciate your time today.

176

My pleasure.

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.
