New study disproves theory that goldfish only have a three-second memory
Your goldfish remembers.

A beautiful goldfish, with a great memory.
It’s long been a common belief that fish have the memory capacity of only a few seconds. People often make fun of people with bad short-term memory by saying they have the “memory of a goldfish.”
This belief about fish spread even further after being highlighted in Disney’s “Finding Nemo” films where Dory, played by Ellen DeGeneres, has a memory that lasts only about 10 seconds. However, a new study from Oxford University may have just proved that we got Dory all wrong.
To find out if goldfish have memories, the team at the University of Oxford trained nine goldfish to swim 2.3 feet and back to get a reward. Yes, goldfish are even smart enough to be trained. All these years they’ve been swimming in circles in small bowls when we could have been teaching them to do some fun behaviors.
The researchers marked off the tank in vertical stripes every ¾ inch.
Once the fish swam the 2.3 feet, they were given a physical cue from a researcher to turn around and swim back to where they started. If they did so, they’d receive a tasty bloodworm.
After the fish got that pattern down, the researchers changed the starting point and didn’t give any cues to turn back. Eight out of the nine fish swam the same exact distance before turning around. It seems that the fish used external cues to mark the distance and then turned around at the appropriate point. This type of measurement is known by scientists as “optic flow.”
This proves that fish actually do have decent memories.
The one thing that tripped the fish up was when the vertical stripes were moved closer together, they didn’t swim as far before turning back.
The fish also didn’t appear to use time as a way of marking distance.
“We did not find a significant effect of time on the distance travelled and the coefficient of variation in time travelled was two to three times higher than the coefficient of variation in distance estimate for most fish,” the researchers wrote. “Video analysis revealed high variation in time spent to perform the experiment within a day or a session without any apparent pattern, further supporting this hypothesis.”
This study definitely changes the way people will look at the film “Finding Dory” and how they relate to their goldfish. Remember that time you forgot to feed him? He remembers.
“Forgetful people say they have a mind like a goldfish, but that’s not fair,” Dr. Adelaide Sibeaux, who led the study at the University of Oxford, told Daily Mail. “Goldfish are clearly not stupid at all, as they have a good memory for distance based on the flow of objects passing by as they swim, like stripes on their tanks.”
“Even when I left for a week for Christmas, and came back to restart the study, they knew how to do it,” she continued.
So next time someone tells you they have the memory of a goldfish, let them know that it’s actually a compliment.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
