Are all of your memories real? - Daniel L. Schacter
Summary
TLDRيتناول النص تجربة من التسعينيات حيث تذكر المشاركون فقدانهم في مركز تسوق كأطفال، رغم أن ذلك لم يحدث فعلاً. التجربة تسلط الضوء على قابلية الذاكرة للتأثر بمصادر خارجية مثل الآخرين أو الأخبار. الذاكرة قد تكون غير موثوقة وتحت تأثير عدة عوامل، مثل الخيال أو المعلومات المنحازة. كما توضح التجارب كيف يمكن للآراء الحالية أن تؤثر على تذكر المواقف السابقة بشكل غير دقيق. لهذه الأخطاء في الذاكرة تأثيرات واقعية في مجالات مثل التحقيقات الجنائية والشهادات الطبية، مما يبرز أهمية الاعتراف بأن الذكريات ليست حقائق ثابتة.

Q & A
ما هو الهدف من الدراسة التي أجريت في التسعينيات حول الذكريات الزائفة في المول التجاري؟
-الهدف من الدراسة كان استكشاف كيف يمكن للأشخاص أن يخلقوا ذكريات زائفة بناءً على معلومات مقترحة لهم، مثل القول بأنهم ضاعوا في المول التجاري كأطفال.
كيف وصف بعض المشاركين في الدراسة ذكرياتهم الزائفة؟
-بعض المشاركين وصفوا الذكريات الزائفة بتفاصيل دقيقة، مثل تذكرهم لرجل مسن يرتدي قميصًا من الفلانيل أنقذهم، رغم أن هذا لم يحدث بالفعل.
ما الذي يوضحه هذا النوع من التجارب حول موثوقية الذكريات؟
-التجارب توضح أن الذكريات قد تكون غير موثوقة ويمكن أن تتأثر بمصادر خارجية مثل اقتراحات من الآخرين أو الإعلام.
ما هو مفهوم التأثير الاقتراحي على الذكريات؟
-التأثير الاقتراحي يحدث عندما يدمج الأشخاص معلومات من مصادر خارجية في ذكرياتهم الشخصية دون أن يدركوا ذلك.
ما الذي أظهرته الدراسة المتعلقة بالصور الجامعية التي لم يزرها المشاركون؟
-أظهرت الدراسة أن المشاركين نسبوا مشاهدتهم لصور الحرم الجامعي الذي لم يزوروه إلى ذاكرة خاطئة بأنهم زاروا الحرم بالفعل في الماضي.
كيف أثرت الدراسة التي استخدمت العدسة المكبرة واللوليبوب على الذاكرة؟
-في الدراسة، تم إظهار صورة لعدسة مكبرة ثم طلب من المشاركين تخيل لوليبوب. في كثير من الأحيان تذكر المشاركون أنهم رأوا العدسة المكبرة واللوليبوب، مما يبرز صعوبة ربط الأشياء بالسياق الصحيح.
كيف تؤثر الآراء والمشاعر الحالية على الذكريات القديمة؟
-الآراء والمشاعر الحالية يمكن أن تؤثر على الذكريات القديمة، حيث يغيّر الناس ذكرياتهم القديمة لتتماشى مع مواقفهم الحالية، كما في حالة الأشخاص الذين غيّروا موقفهم من تقنين الماريجوانا.
ما هو تأثير معرفة نتائج الأحداث على تفسيرات الماضي؟
-معرفة نتائج الأحداث تؤثر على تفسيرات الماضي. المشاركون الذين عرفوا من فاز في الحرب قيّموا الجانب الفائز بأنه كان لديه فرصة أكبر للفوز، رغم أن هذه المعلومات لم تكن متاحة عند التقييم الأولي.
كيف يمكن أن تؤثر ذاكرة الشهود غير الدقيقة على التحقيقات القانونية؟
-إذا تم استخدام أسئلة موجهة خلال التحقيقات، فإن التأثير الاقتراحي يمكن أن يؤدي إلى تحديدات خاطئة أو اعترافات غير موثوقة. حتى بدون أسئلة موجهة، يمكن أن تؤدي الأخطاء في الذاكرة إلى شهادات شهود غير دقيقة.
ما هي الآثار العملية لتحيز الذاكرة في مجالات مثل القانون والطب؟
-تحيز الذاكرة يمكن أن يؤثر على مجالات مثل القانون، حيث قد لا يستطيع المحلفون تجاهل الأدلة غير المقبولة، وفي الطب، قد تؤثر المعرفة بتشخيص سابق على رأي الطبيب الثاني.
Outlines
🔍 False Memories of Childhood Incidents
In a study from the 1990s, participants were led to believe they had been lost in a mall as children, with some recalling vivid but fabricated details. This experiment shows how false memories can be implanted through suggestion, especially when the information comes from trusted sources, like parents. A significant portion of the participants believed these false memories, highlighting the unreliability of memory and how easily it can be influenced by external factors.
🧠 The Role of Suggestibility in Memory Formation
The mall study reveals how suggestibility can cause people to adopt external information into their memories. This concept extends to other situations, like a study where participants were shown photos of a campus they had never visited. Many later believed they had been there, demonstrating how memories can be shaped by misattributing experiences. This suggests that our minds sometimes fail to distinguish between real and imagined events.
🔄 Mixing Real and Imagined Experiences
In another experiment, participants confused objects they saw, like a magnifying glass, with things they were merely asked to imagine, like a lollipop. This shows how easily we can blend actual experiences with imagined ones, struggling to recall which is which. This misattribution blurs the line between real and imagined memories, further complicating the reliability of recollections.
🕰️ Memory Bias and Changing Views Over Time
A study from the 1970s and 1980s revealed how current beliefs influence our memories of past opinions. Participants who changed their stance on marijuana legalization often recalled their past views as aligning with their current ones, demonstrating that memory can be reshaped to match present-day beliefs. This bias reflects how our present feelings can distort our recollections of past thoughts and attitudes.
⚖️ How Knowledge of Outcomes Skews Memory
Participants in a study were asked to predict the outcome of a historical war. Those who were told the actual outcome rated the winning side as more likely to win, even though both groups had the same information. This 'hindsight bias' shows that knowing the result of an event can alter our perception of how likely that result was, distorting our memory of past judgments.
🚨 Real-World Consequences of Memory Fallibility
The inaccuracies of memory can have significant impacts in areas like law and medicine. Leading questions in police interrogations can implant false memories, while misattribution can affect eyewitness testimony. In courtrooms, jurors may struggle to ignore inadmissible evidence, and in medical diagnoses, prior knowledge can bias a second opinion. These examples show how memory's subjective nature can influence critical decisions in real-life situations.
🔄 The Fluid Nature of Memory
Our memories are not perfect reflections of reality but rather subjective perceptions influenced by various factors. This fundamental characteristic of memory is not inherently problematic unless we treat memory as fact. Accepting the malleable and often unreliable nature of recollections can help us better understand the limitations of our memories.

Highlights
In a 1990s study, participants falsely recalled getting lost in a mall as children after being told their parents confirmed the story.
A quarter of the participants in the mall study believed they had actually gotten lost, despite it being a fabricated memory.
The study highlights how suggestibility can lead to the creation of false memories based on outside information.
Our memories are often unreliable, and research is still uncovering the neurological reasons behind this fallibility.
Another study showed participants images of a university campus they'd never visited, and weeks later, most believed they'd been there.
People often misattribute information from one context, such as an image, to another, like a memory of an actual experience.
In an experiment, participants who imagined a lollipop after seeing a magnifying glass often misremembered seeing both objects.
A study on marijuana legalization found participants changed their memories to match their current views, highlighting the influence of personal bias.
Participants in a war study rated the winning side as more likely to have won if they were told the actual outcome, despite having the same prior information.
This bias occurs because knowing an outcome can influence how people perceive the likelihood of that result, even though probabilities shouldn’t change after the fact.
False memories and biases can have serious real-world consequences, such as leading to unreliable eyewitness testimony in court.
Police interrogations using leading questions can inadvertently suggest false memories to witnesses or suspects.
Misattribution can cause witnesses to wrongly recall details, resulting in incorrect identifications or false confessions.
Even when a judge rules evidence inadmissible and instructs jurors to disregard it, memory bias may still affect their judgment.
In medical settings, second opinions can be biased if the second doctor is aware of the first doctor’s diagnosis.
Memory is a subjective perception of reality, and problems arise when we mistake it for an accurate and objective representation of the past.
Transcripts
In a study in the 1990s,
participants recalled getting lost in a shopping mall as children.
Some shared these memories in vivid detail—
one even remembered that the old man who rescued him
was wearing a flannel shirt.
But none of these people had actually gotten lost in a mall.
They produced these false memories
when the psychologists conducting the study told them they’d gotten lost,
and although they might not remember the incident,
their parents had confirmed it.
And it wasn’t just one or two people who thought they remembered getting lost—
a quarter of the participants did.
These findings may sound unbelievable,
but they actually reflect a very common experience.
Our memories are sometimes unreliable.
And though we still don’t know precisely what causes this fallibility
on a neurological level,
research has highlighted some of the most common ways our memories
diverge from what actually happened.
The mall study highlights how we can incorporate information
from outside sources,
like other people or the news,
into our personal recollections without realizing it.
This kind of suggestibility is just one influence on our memories.
Take another study,
in which researchers briefly showed a random collection of photographs
to a group of participants,
including images of a university campus none of them had ever visited.
When shown the images three weeks later,
a majority of participants said that they had probably or definitely
visited the campus in the past.
The participants misattributed information from one context— an image they’d seen—
onto another— a memory of something they believed they actually experienced.
In another experiment, people were shown an image of a magnifying glass,
and then told to imagine a lollipop.
They frequently recalled that they saw the magnifying glass and the lollipop.
They struggled to link the objects to the correct context—
whether they actually saw them, or simply imagined them.
Another study, where a psychologist questioned over 2,000 people
on their views about the legalization of marijuana,
highlights yet another kind of influence on memory.
Participants answered questions in 1973 and 1982.
Those who said they had supported marijuana legalization in 1973,
but reported they were against it in 1982,
were more likely to recall that they were actually against legalization in 1973—
bringing their old views in line with their current ones.
Our current opinions, feelings, and experiences
can bias our memories of how we felt in the past.
In another study,
researchers gave two groups of participants background information
on a historical war and asked them to rate the likelihood that each side would win.
They gave each group the same information,
except that they only told one group who had actually won the war—
the other group didn’t know the real world outcome.
In theory, both groups’ answers should be similar,
because the likelihood of each side winning
isn’t effected by who actually won—
if there’s a 20% chance of thunderstorms, and a thunderstorm happens,
the chance of thunderstorms doesn’t retroactively go up to 100%.
Still, the group that knew how the war ended
rated the winning side as more likely to win than the group who did not.
All of these fallibilities of memory can have real-world impacts.
If police interrogations use leading questions with eye witnesses or suspects,
suggestibility could result in incorrect identifications or unreliable confessions.
Even in the absence of leading questions,
misattribution can lead to inaccurate eyewitness testimony.
In a courtroom,
if a judge rules a piece of evidence inadmissible
and tells jurors to disregard it, they may not be able to do so.
In a medical setting, if a patient seeks a second opinion
and the second physician is aware of the first one’s diagnosis,
that knowledge may bias their conclusion.
Our memories are not ironclad representations of reality,
but subjective perceptions.
And there’s not necessarily anything wrong with that—
the problems arise when we treat memory as fact,
rather than accepting this fundamental truth
about the nature of our recollections.
