LSD Changes Something About the Way People Perceive Time, Even At Microdoses (vice.com)
An anonymous reader quotes a report from Tonic: The perception of time is a fundamental process of the brain, linked tightly to attention, emotions, memory, psychiatric and neurological disorders, and even consciousness -- but while scientists have been anecdotally noting how drugs can change time perception for decades, very few have been able to address the question rigorously with tightly designed studies. Cognitive neuroscientist Devin Terhune says he's been interested in understanding the neurochemical mechanisms involved in the distortions in the perception of time, and these drugs are one way to do that. Psychedelics act on specific pathways and chemicals in the brain, and if they also change the perception of time, we could learn exactly how it happens. At the end of November, Terhune and his co-authors published a randomized, double-blind, placebo-controlled study in Psychopharmacology on the effects of microdoses of LSD on people's perception of time. They found that even at small doses, LSD seems to change the way people interpret time, though the specifics of how and when are still to be determined.
In the new work, 48 healthy people were split up into four groups. One group got a placebo, and the other three received different small doses of LSD: 5, 10, or 20 micrograms. Then, they did what's called a temporal reproduction task. In this task, you see something on a screen for a certain amount of time -- in the study it was a blue circle -- and are asked to remember and recreate how long you saw it. The participants were shown a blue circle for periods of time from 800 milliseconds all the way up to 4,000 milliseconds, in increments of 400 milliseconds. Terhune and his colleagues looked to see how accurate the different groups of people were in reproducing those intervals, and found that the people in the LSD groups tended to hold down the space bar for significantly longer periods of time than the placebo condition. The researchers call this "over-reproduction." "Terhune says that they saw these changes in time perception without any major conscious effects from the drug," the report adds. "They asked people to report if they felt anything from taking the LSD, like perceptual distortions, unusual thoughts, if they felt high, or if it affected their concentration. There were a couple of weak effects, but statistically, the change in time perception happened independent of any subjective influence of the drug."

They were all wearing Rolexes and snorting cocaine !!!!
But you ... YOU !!! Your face is MELTING !!!!!!!!!
I think if I hit you with this chrome plated axe that will make it STOP.
I wonder how the effects compare to Heptapod B, for changing time perception.
The living have better things to do than to continue hating the dead.
It's because they tested using their eyes as the sensor. It's common knowledge that LSD has a side effect of having longer lasting optical impressions, aka "tracers". That doesnt mean their sense of time was actually affected. They really did "see" it that long.
Pot changes perception of time way more than acid.
Coming up next, we'll study if LSD changes something about the way people perceive....sound!...and then...light!....and then....taste!...and then...bunnies!...

It's a drug, it fucks with your brain. How profound is it that effects your sense of time perception? Not at all.

It's not just LSD. Music can have this effect too. For that matter, almost anything. . . ever been to a boring presentation that seemed to drag on for days ?

How is this news? In 2000 I took 6 tabs and we somehow stumbled across the South Park movie on TV. It lasted for eight hours and our chests hurt from laughing.
Acid makes 5 minutes feel like an hour. Did that need studying?
Since various Yuppie types have advocated taking microdosed LSD to increase their creativity at work, I wonder what affect this has on their ability to drive?
If only it made people perceive time being slower by enhancing senses and shortening reaction times... but no, it seems LSD just fucks people up. Well, who would thought, right? Thanks scientists!
So does electric shock. It isn't magic. You mess up the brain you get all kinds of weird effects.
or it could just be the LSD....

I'm going to be writing a paper on the topic. Let's just say if you follow numerology and the birth rights of another human being, the "flipping" of consciousness is completely possible. There is a dirty phase in life, and there is a clean phase of it. I'm going to be writing a few papers with the information that I've gathered over this last weekend. It's entirely adequate timing I'm back in school and my first paper is already gaining traction at the levels I did not expect it to. Wait for the next ones.
In laymen's terms, stoned.

It's called "the don't give a fuck" effect which is brought on when tripping on LSD.
Time, what's time man, wow.
Go well
You'll remember them.... the more time you remember the longer it seems.

Two years of my youth simply vanished, compared to my peers. Then three hours every Sunday.
Don’t get me started on the temple sessions where time moved so slowly that the only way to escape was by dozing.
Would be interesting if this is the majority effect from micro dosing. That you're basically taking these sub threshold experiences/ideas, and making them act for longer in our consciousness. Long enough to actually notice them perhaps.
Or if this is just that our minds take longer to settle into "yep, noticed that" and this test is simply measuring all of that process.
Pot makes you perceive time differently, usually slower than normal. As is the same for alcohol and any and all other mood altering drugs. Why the fuck do you think we do drugs. That is actually a statement, not a question. So no, I'm not missing a question mark.
I did a lot of acid as a kid, and it didn't have any long term negative effects, despite what the voice that comes out of my bathroom sink says.
You are welcome on my lawn.
Well time is weird stuff. How do you know you're perceiving it "correctly"? You're soaking in it.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
I just want to extend my thanks to Captain Obvious and his study team! Clearly mind bending revelation...not.
Yes
Perhaps its as simple as the unit of perceived time = memories.
Do you remember what you did yesterday? The same boring stuff you wipe from your memory? So that day is nearly zero time, it is one memory = generic boring work day memory #20.
Did you take drugs, did everything seem different, eating, drinking, breathing, walking, all weird? That's a lot of memories. So that day is lots of time = drank on drugs, talked on drugs, ate on drugs, .....
I remember the first time I was drunk, everything seemed to be in much more detail. It wasn't the alcohol, it was the difference between normal and alcohol, causing me to examine the micro detail of everything because it was slightly different.
If only I had a snappy come back, instead of this wicked flashback. BTW, love the rainbow colors on the letters in the article. Music sucked, but totally trippy. 4 stars.
... your brain is slower when on drugs.
I don't need a research paper to see that. I just have to watch people trippin'.

LDS speeds up the refresh rate of your brain. You might "see" the object every 50ms normally. With LSD you "see" the object every 5ms; you're paying more attention more often, and we measure time by attention. 10x more views = 10x more time, give or take.
Sit in a bar and you'll see time fly by, sit in a meeting and you can watch seconds turn to hours.
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
Time is the measure of change in our environment.
Therefore its perception is entirely subject to our sensory input.
The life cycle of our cells modulates our sensory input.
Our cells experience their environment individually.
Therefore our cells each perceive time uniquely.
Our consciousness is an averaging of all our cells' experience.
Socially, because we are all composed of similar components we have a similar experience of time.
"Consensus" in science is _always_ a political construct.
...if you give a dude some acid, let him trip for a few hours then tell him what time it is, he'd be like; "whoa". We require further funds to test MDMA in a similarly thorough fashion.
Oohh and horse tranquilizers!
Every page, and every word, in a 226 page novel exists at once on the shelf. If our brains were much larger, we could read not just a letter, or word instantaneously. If our minds were bigger, we could read pages, chapters, the entire novel at one time. Time is something we project in order to be able to digest our existence. So a mind-expanding drug could change this. Kurt Vonnegut explained this in Slaughterhouse Five - and was accused of dropping LSD. I discovered it 20 years before I read Vonnegut ....... so it goes.
Gently reply
.lot a explains that , Well
I have seen someone come out of a 5 minute DMT trip and think they had been under for hours.
I cant be randomly harrassed and forced to give samples of my precious bodily fluids to my employer. It sounds like you have a real SHITHOLE COUNTRY with no unions to protect you. SAD!
I think anyone who's ever tried it could have told you immediately that it changes your perception of time. I vividly remember dosing on a Friday and being worried that I would be late for work when I didn't have to work until Monday. I knew how many days it was, and I could calculate the hours with no issue, but perceiving how long it would actually take for me to get to Monday and be sober was impossible.

Ken Kesey described his experiences on LSD when he volunteered from the CIA's MKULTRA experiments. He pranked the researchers through the whole thing. Of course, one of the evaluations was to check the subjects' perception of time. Of course his sense of time was wasted (they used pretty high doses), but Kesey noted that the idiot checking wore his wrist watch into the room. So Kesey just checked the second hand on the guy's watch, and was able to tell him how much time had passed to the second.
Funny how researchers never consider things like that.
