Can being drunk cause false memories?
Highlights. Witnesses, victims, and suspects are often intoxicated with alcohol or other drugs. Substances can increase susceptibility to false memory formation and suggestibility. Substance effects vary depending on substance type, dosage, and time of testing.
Like milder alcohol–induced memory impairments, these periods of amnesia are primarily “anterograde,” meaning that alcohol impairs the ability to form new memories while the person is intoxicated, but does not typically erase memories formed before intoxication.
There is currently no way to distinguish, in the absence of independent evidence, whether a particular memory is true or false. Even memories which are detailed and vivid and held with 100 percent conviction can be completely false.”
While alcohol does make you tell the truth in most cases, people can still lie while under the influence. Context can help determine whether someone who's drunk means what they say. Negative comments and anger while drinking tends to be defense mechanisms and may not necessarily stem from the truth.
Alcohol-related blackouts are gaps in a person's memory for events that occurred while they were intoxicated. These gaps happen when a person drinks enough alcohol to temporarily block the transfer of memories from short-term to long-term storage—known as memory consolidation—in a brain area called the hippocampus.
- Inaccurate perception. Sometimes the problem begins while the original event is still occurring, that is, while the memory is being encoded. ...
- Inferences. False memories may also arise from inferences made during an event. ...

- Similarity. ...
- Misattributions of familiarity.
According to Duke University, the inability to remember anything from a night out usually occurs after a person has had five or more drinks. Alcohol affects short-term memory by slowing down how nerves communicate with each other in a part of the brain called the hippocampus.
"There's usually some version of one's true feelings that come out when one is drunk," Vranich said. "People dredge up feelings and sentiments from somewhere deep in their brains, so what one says or does certainly reflects what's going on deep down.
- Intolerance for uncertainty.
- Constant doubts about memories.
- Impulsive, intrusive thoughts.
- Avoidance of specific places or people.
- Distress about certain topics.
- Following strict routines.
- Attempting to garner reassurance from others.
- Engaging in ritualistic behavior.
Definitions of False Memory
Some common elements of false memory include: Mental experiences that people believe are accurate representations of past events. Trivial details (believing you put your keys on the table when you got home) to much more serious (believing you saw someone at the scene of a crime)
What are the two types of false memory?
Instead, fuzzy trace theory puts forward the idea that there are two types of memory: verbatim and gist. Verbatim memory is when we can vividly remember something in detail, whereas gist memories are fuzzy representations of a past event — hence why the theory is called "fuzzy trace."
An individual might struggle with one false memory at a time which they are extremely focused on, or they may have multiple false memories at once. False memories can last for a long period of time, lasting several months or even years.
Neuroscience says no. If you're drunk, it may feel like your personality has undergone a dramatic shift. But as a team of scientists from the University of Missouri found, sober observers of drunk people don't report such a shift.
But, the most important question here is - do drunk people mean what they say? The simple answer to that is, yes, they do. Alcohol is not a mind-altering substance, like some others. It doesn't put in an alternate state of mind where we hallucinate, or experience extreme moods.
A short-term effect of alcohol abuse on the brain is ethanol reducing the communication amongst brain cells. As a result, many people start to loosen up their inhibitions when they begin drinking. This leads to people saying whatever thoughts pop up in their minds that they would've normally repressed.
Alcohol lowers inhibition and makes people feel talkative, extroverted, and emboldened. The result is drunk blabbermouths who overshare and say embarrassing or regrettable things.
Research shows that the methodologies that use longer encoding periods, repetition, emotion, and a lot of detail and complexity create false memories that feel and look more real (Jou and Flores, 2013).
Spontaneous false memories are false memories that arise without external suggestive pressure and develop because of internal processes such as, for example, spreading activation (Howe, Wimmer, Gagnon, & Plumpton, 2009).
The studies found that highly attachment-anxious people were the most susceptible to creating false memories when viewing a video of a person, regardless of whether the subject discussing a relationship breakup or something less personal.
According to the NIAAA, alcohol interferes with the brain's development of new memories. This means people who drink heavily are more likely to forget anything that happened during the time they were drinking but will remember events before it. This is known as an alcohol-induced blackout.
Do people forget what they say when they're drunk?
Although a person does not lose previously learned information, he or she may also find it more difficult to recall certain facts while intoxicated. Yet once a person sobers up, his or her memory and ability to learn new information are not permanently affected.
These short-term memories can arise by association. For example, an individual with a sexual obsession may obsess over a false memory of touching their significant other without consent. Substance use can aggravate the symptoms of False Memory OCD, especially in those with harm and sexual obsessions.
When you have OCD, you may experience false memories that feel like real experiences. This may lead you to doubt your recollection of important events or your memory performance in general. This lack of confidence, in turn, may lead you to more false memories.
One way in which false memories can be reduced is to en- hance the encoding and subsequent recollection of source- specifying information. For instance, allowing individuals to repeatedly study and recall the related target words re- duces false memory errors in the DRM paradigm.
Examples of False Memory
Believing that you had called a friend in the morning, when in actuality, you had not. Falsely recalling that you had submitted an assignment for a class, only to find out later that you had not. Incorrectly remembering that you locked your car when before leaving the parking lot.
New Study Finds That False Memories Linger for Years. True memories fade and false ones appear. Each time we recall something, the memory is imperfectly re-stitched by our brains. Our memories retain familiarity but, like our childhood blankets, can be recognizable yet filled with holes and worn down with time.
False memories commonly activate the anterior/dorsolateral prefrontal cortex (A/DLPFC) and the hippocampus. These regions are assumed to work in concert during false memories, which would predict a positive correlation between the magnitudes of activity in these regions across participants.
An autobiographical false memory is an incorrect recollection of part of an event, or an incorrect recollection of an entire event. The person recalling a false memory believes that they are accessing a real memory – it is not an attempt to lie (e.g., Loftus, 2005).
Delusion is commonly defined as a false belief and associated with psychiatric illness like schizophrenia, whereas confabulation is typically described as a false memory and associated with neurological disorder like amnesia.
False memories are events recalled by a witness that did not actually happen. There is research which suggests that up to 20% of those studied maintain a record of detailed personal memories that are completely false (Mazzoni, Scoboria, and Harvey, 2010).
Can false memories be harmful?
False memories have also been implicated in several serious cases, some fatal. In such instances, false memories have had a dramatic and disturbing impact on people's lives. False memories have also led to false accusations and false convictions for various crimes, including sexual abuse.
False memory is one type of memory process that has been shown to be affected by stress. There is a definite need for further research in this area, with results possibly having important implications for real-life situations such as eye-witness testimony or stressful situations such as exams.
"With larger doses of alcohol, not only can a person lower their inhibitions, but their emotions can also be altered," Glasner explains. This combination of decreased inhibition and increased emotion can create a perfect storm for physical affection.
Alcohol increases irritability and decreases inhibitions. With this combination, there is a chance you could be more mean or aggressive toward others. Alcohol clouds your judgment and leads to communication problems. This is especially true if the other person is also under the influence.
Alcohol stifles reasoning skills and contemplating repercussions. As a result, people are more likely to tell the truth while intoxicated, offering up brutally honest, unfiltered opinions. And without the fear of consequences, alcohol can give people the courage to do or say things they ordinarily wouldn't entertain.
Many studies show that after one drink—or two in men who weigh more than around 190 pounds—modest consumption up to a blood-alcohol level of around 0.08 percent, the legal definition of intoxication while driving, is associated with greater libido and more sexual activity.
No matter how triggered you may feel, or how important the issue at hand may seem, you cannot reason with someone who is intoxicated beyond the point of understanding. If you find yourself arguing with a drunk person, do your best not to engage with them until they've sobered up.
Studies show that, in many cases, people mean what they say when drunk. However, they still may not have as much control over their words. To better understand the concept, it is crucial to know how alcohol and addiction affect the brain.
In alcohol-related psychosis, symptoms of psychosis present during or shortly after heavy alcohol intake. Clinically, alcohol-related psychosis is similar to schizophrenia but has been found to be a unique and independent condition. It is characterized by hallucinations, paranoia, and fear.[1][2][3]
Alcohol has an effect on brain chemistry - it can induce panic because of its effects on GABA, a chemical in the brain that normally has a relaxing effect. Small amounts of alcohol can stimulate GABA and cause feelings of relaxation, but heavy drinking can deplete GABA, causing increased tension and feelings of panic.
What is it called when your brain makes up false memories?
No one's memory is 100% percent accurate, but some people make many memory errors. They believe in the accuracy of these faulty memories and can be convincing when talking about them. This is what scientists call confabulation.
People with False Memory OCD experience frequent doubts about things that have happened to them and may be convinced they've done something wrong despite no evidence of these memories being true (e.g., “Did I accidentally steal and don't remember?”).
False memories become recurrent and intrusive thoughts that, in turn, increase doubts about what really happened. These persistent doubts (obsessions) might cause you to constantly check or engage in rituals to relieve the distress they cause you (compulsions).
Intrusive thoughts or believing things that aren't actually true can happen if you have anxiety. For example, you may be so fearful or worried about something happening, you start believing it absolutely will happen.
