If you couldn't process multiple streams ( audio/visual/other senses ) how would you ever be able to monitor the background for danger and context switch? There is a difference between conscious experience and what's going on in the background.

This is about multiple speech streams. More specific from the mere ability to process multiple sensory streams in general.

  Sure. Still don't see why the result is at all surprising. If you couldn't process multiple streams ( I see nothing special about speech - note parsing speech is potentially different from thinking over the top - ie the difference between hearing and listening ) simultaneously it's hard to see how you'd last 5 minutes.

There’s a big difference between processing multiple streams, and processing multiple streams simultaneously. You can achieve the former, without the latter, by doing time slicing. Spending a small amount of time processing stream A, then dropping that and processing stream B for a moment, then swapping back. Just like how a single core CPU can process multiple threads. Proving the brain is continuously processing and encoding multiple streams simultaneously is an interesting finding that helps us better understand how our brains handle multitasking. That’s absolutely something worth studying and understanding, even if the headline discovery “feels” obvious. It the precise mechanism that’s interesting, not the effect the mechanism produces.

  When I meditated a lot, I was able to sit in a cafe and listen to 3 conversations without switching and be able to understand them and remember them all. It happened to me few times. Also, once, sleeping in a tent, a voice from a dream interfered with sound of raindrops and became distorted and I woke up scared only to quickly get what just happened.

    Not sure why you are downvoted. Well it probably doesnt require meditation because split attention is somewhat common here. My mother can follow multiple discussions like have a phone conversation and understand what I tell her. In general I can't. So a bit harder for me. I can focus on work and follow some podcasts but not speak and at the same time listen to a full parallel convo. I do believe brain to brain communication exists from experience too. People will be quick to call it schizophrenia and indeed it can be maddening because it evidently reuses your neurotransmitters for information propagation. That includes dopamine and can lead to the same issues some diagnosed people have, but actually a couple at the same time. Without visual hallucinations but the brain gets a bit taken still, since it has to share processing. So it can induce adhd like symptoms, loss of phantasia, nucleus acumbens becoming nucleus incumbered :D, impaired motivation, etc.. But it is transient and you can argue it within yourself with some amount of relief. If you notice and start a loop of wondering where it comes from you are toast though. Anyway, probably saying too much. You have to experience it. Probably someone playing with AI and neurochemistry. Still can't figure out the actual transport system. It does not make much sense from a wavelength point of view. Even if merely HF acoustic waves (since they can be more directed) not quite sure. Should ask whoever big galaxy brain created the havana effect... \sarcasm At the same time people already know publicly how to decode brain signals and turn them into movements and Computer Interface actions. So the brain is not a complete blackbox. Some people might be further along... Anyway... we will know eventually what is this all about..

      likely related to how trained and some untrained dogs sense what you are up to consciously or not (yet). brains smell/decode info that we don't have an actual odor (but receptors) for. it's also why (some) pets and animals react to their human's mood/attitude and short-, mid-, long-term stress (and other) hormone levels. some people get their energy drained by persons that they are not even aware of being in proximity (e.g. dad got home after work while child is wearing headphones). it can become a matter of good or bad resilience, too, and some brains can develop defence mechanisms by mere exposure while others can't, which is likely (definitely) entangled in/with hormone metabolisms.

There is also a different quality of processing. Textunderstanding and danger deciphering of signals.

  Sure. Have you ever listened to music while simultaneously writing a comment on hacker news - and managed the split cognitive load effortlessly?

    No, have you ever assumed that everyone surrounding you is exactly the same because mirror-neurons? Because i never did that- i just know..
