Monkeys can sense their own heartbeats

Are there MSR tests that used windows to other animals/puppets with marked spots instead of mirrors as a control?
Still, "marked part of the animal is itching me" shows that the animal can identify a marked body part in the image (e.g. forehead) and indicate the corresponding part on it own body. The "self" concept has to be involved there to some degree even if not to the point of "the animal I see is actually me".
When I mentioned the "itch", it was mainly about the reflex a lot of animals have, not a "conscious identification". Think about reflexively licking your lips when you see someone else get sauce/cream/beer-foam on their lips, or even the reflex of getting aroused when observing others being aroused?
> We first got our monkeys to sit in chairs in front of a computer screen and hooked them up to electrocardiograms to monitor their heartbeats. Then we played videos of either a yellow or green cloud bouncing up and down accompanied by beeping sounds. Sometimes we would sync the bouncing and beeping to match the monkey’s heartbeat, and at other times they were out of sync.
> We then used eye trackers to measure how long the monkeys looked at the images. If the monkeys had a sense of their own heartbeats, they would find the in-sync bouncing less interesting and novel than the out-of-sync bouncing and so would spend more time looking at the out-of-sync image.
I wonder if you could get them to tap along or similar to a sensor that was beeping to their heart beat where you made the beep quieter and quieter until eventually silent.
It's hard to phrase because obviously the claim isn't they understand what it is etc.
Certainly if it's beating fast I notice much more than resting.
I think at rest I tend to notice it indirectly, particularly how it makes my body move or noticing it alongside a deep breath.
If for some reason verifying it would actually impact your life, try to find definite proof for it, but otherwise this type of thinking is generally detrimental as you end up with snowflake syndrome and will ignore meaningful statistics or advice as "not applicable to you" when in all likelihood you're just like everyone else.
"some times more than others" means "more than other times", not "more than other people". Meaning that there are times I'm more sensitive to it than other times. It's a sensation that fades into the background most of the time.
It would be totally insane for me to assume I'm especially good at it.
But even in the dark, even if I can't consciously feel it, I can somehow still sense it.
