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.
Perhaps a dumb question but are they center panned (or mono, i.e. talking over each other) or is it split left ear/right ear when they come through the headset?
Airplane radios are generally broadcasting and receiving mono. There are modern headsets that can also play stereo, but only for onboard music or intercom purposes, if the plane supports it. But in planes with 2 radios you can usually configure their I/O individually. So you can listen (and also talk, although that makes sense less often) on two frequencies at the same time.
Yes of course, the transmitted audio would be mono. I meant one radio in one ear and another radio in the other ear, or if you mix them and they both play in both ears. But it sounds like they're mixed (talking over each other in a single audio stream).
They are mono, but I was trying to say that with practice, you can process 2 independent audio streams simultaneously irrespective of whether they are mono or stereo. For example, I am able to keep track of 2 people talking at the same time. I obviously can't respond to both but can maintain independent contexts.
That tracks. As a teacher I sometimes find myself conversing with multiple kids simultaniously as well. If it's nothing too deep that requires full focus, it works. (Though I do find it tiring and avoid it.)
Many mindfulness practices seem to direct attention at two place at once, to quiet the inner voice. Perhaps this relates to more than just speech, but to attention itself. George Gurdjieff's "The Fourth Way" deals with self remembering, and his pupil, P. D. Ouspensky, has a very vivid description in [1] of how focusing on two things at once leads to a changed state of consciousness, that seems like meditation, and comes from the saturation of the two streams of attention.
Listening to two talkers at a time is certainly doable...
As is talking whilst listening to another conversation - eg. Giving a lecture whilst eves dropping on the people talking at the back of the lecture theatre.
However, having a two way conversation with one person whilst listening to another is really hard.
I'm a native English speaking pinball freak living as an expat in a German-speaking country, and I find myself often listening to English speakers on the train, while also carrying on a conversation in German .. and I have observed that the same part of my mind that can handle multi ball-pinball events, where during a pinball session multiple balls are in play, 'feels' active.
Its a kind of context juggling mechanism in both cases, and it feels like the same mental muscle being exercised in both cases.
I wonder if there is a worthwhile experiment to be conducted wherein an EEG'ed pinball player gets to play pinball with easy multi ball targets, while also listening to German and English speakers, and then passing a test at the end of it .. because I sure have been preparing for that kind of scenario lately ..
Then it is known that if you play to someone with small delay what he says he will be lost on both - so he can't think about and listen to what he is saying if it's not one stream.
This makes me wonder how much of paying attention is really prioritization rather than filtering everything else out. We probably process far more than we're consciously aware of.
In pinball, we have these events called "multiball" where more than one ball is brought into play on the table - and very skilled players use these multiball events to skyrocket their scores .. as I become more skilled at multiball I find that I exercise the "prioritization" scheme, isolating and identifying which ball in the set needs to be cared for, over which can be ignored for a few milliseconds. I am also multi-lingual and often hear multiple conversations in both languages when I am out in public - I lately observed that this context-switching is very similar to multiball, insasmuch as successful processing of both kinds of input requires a prioritization factor.
In the easiest look at people like me who complain very quick if something is wrong like to warm to cold to sweaty etc. and others not even ackknowliding it at all
Many dj mixers offer the option to split the main mix to one ear and the cue’d track to the other, i have never been able to mix like that, only with cue on headphones and main mix out in the room/monitors. Weird
This is maybe only tangentially relevant to the linked study, but I've noticed I can read aloud from a book on autopilot while thinking about other things or even thinking back on past conversations. I could not do this a few years ago, but now it happens on its own. I wonder how that relates to attention and speech streams
Not reading out loud, but I've caught myself a few times on reading and not processing that, because I was thinking about something else. Like I still did the reading, but straight to /dev/null of my brain
I think everyone does this. It reminds me of a possible related phenomenon. The act of remembering what you do takes a few extra brain cells, to enable the “recording function “. If you are on complete autopilot, doing a routine task, you will often forget to turn on the recording function. Like the other day I tried to remember whther I had run the dryer and realized it had been completely optimized out of my memory.
I experienced this too, when I started reading out loud more. At first, it was just that my eyes would scan ahead a bit from what I was saying, to help me get the right emphasis by knowing where the sentence was going. It felt like I had "handed off" saying the words out loud to a "subroutine", so my attention could be on what I was reading. Then that "readahead" extended to a whole sentence. And at that point it was like I was so far ahead of what I was saying that I had time to think about it a bit. And then at some point it was like the "reading the words" part got handed off to a "subroutine" too, so my attention could mostly stay on whatever I was thinking
This is something that has been studied and is apparently more common when reading out loud. I have this as well. I can read to my kids and at the same time plan the upcoming day. Pretty neat!
This is a completely different phenomenon. Your ear/brain are tuned to rhythmic beats in the lower frequencies (footsteps). We're better at pattern recognition with the lower frequencies.
Also, our brains will encode the differences in registers to evoke emotion differently, which is often used by horror films to make a scene scarier[0]. Evolutionarily this is probably to detect screams or babies crying, a rustling bush, etc.
Speech encoding, at least per this article, has little to do with that. We don't have music encoding so much as we have pattern recognition, instinctual emotional respond to sound, etc.
Another great video about how music is perceived in animals is [1], just while we're on the topic.

Whenever I’m in multiple conversations at once in a social setting, I think of Pythagoras

Not sure why.

Its def a spectrum.

I wonder if reading aloud might be like walking. I can be walking and speaking to a person at the same time.
