Just because you've trained yourself to involuntarily make impulsive movements that don't "feel" like your own, does it not necessarily mean there's much intelligent thought behind them.
Jeez i appared to overstimate possession, but something i would really like to know, is it possible to my subconcious do those movements INSTEAD of the tulpas themselves? (i mean in the same way if a person that doesn't have tulpas would try doing this). What i mean by this, is that this isn't after all a reliable way of confirming tulpas's mental answers and using this was a way to confirm which things i heared from my tulpa were the tulpa or intrusive thoughts? Because after all this was mostly the biggest reason i learned possession after all so that i could have then bend a finger for YES and another for NO, because without this how am i supposed to GUESS when it's them talking or intrusive toughts? Unfortunately even in the case of my oldest tulpa (pandora with 5 months) her toughts still feel exactly like mine even tough she has her mind voice (which by the way was a voice i trained for her from the anime character).
There's not much I can do for you, other than advising you to do some more activities with your tuppers that require multitasking and thinking about many things simultaneously. Much of the time, parallel processing seems to come by itself for people that interact a lot with their tuppers, be it through regular conversation or adventuring in the wonderland. In the wonderland, you have to keep in mind what you're doing, what your tuppers are doing, and where things in the wonderland are, for instance.
Hum... wait a minute, and what about having any kind of activities involving two or more tulpas interacting with each other at the same time ? I often do this, also quite often i tried to visualize more than 2 tulpas moving and i notice my mind switching rapidly between each (it seems my mind is able to handle at least 2 at once in maximum) i hope this is very good for paralell processing too.
Even my guide's parroting approach is an example of a multitasking activity, as you constantly have to think about what the tupper thinks, what it would say, and so on. Not that I'm telling you to parrot, of course.
Actually until a few weeks ago i never parroted my tulpas on purpose because i always were a lot parrotnoid, but since i got so desperate with that, i finally parroted them for the first time on purpose to see if they would be able to interrupt me. I actually parroted them and i immediatly notice a HUGE difference! The way of them talking was quite different, it was more "basic" (less complex), it felt a LOT forced, i had ZERO doubts about parroting (which means... when i doubt i am parroting is because i am NOT! Which is amazing), and i noticed i had to make a HUGE mental effort to came up with logical answers they usually came up in a more natural way. The problem is that with intrusive thoughts it's a very different story, those never feel forced and also come naturally BUT usually they are always about hearing my tulpas being rude and being mean to me without any appearent reason, so it's usually easy to know when this happens. Also my oldest tulpa (Pandora) actually cried when i was "putting words" in her mouth and begged me to stop (literally) so i promised to never parrot her again at least without her permission (i don't think her crying and begging was a intrusive tought since the tought was actually a lot more persistant and resistant to change than the usual intrusive toughts and i felt resistance when trying to ignore that, altough i didn't felt any emotion from her, which i usually do in cases like this). At first i tought this happened because of my expectation they wouldn't like this, but at the time i only had two tulpas and the other tulpa didn't cried, he appeared to not care about being parroted at all so i don't think this was caused by expectation actually i was expecting more about them being angry rather than sad and crying so it was surprising to hear her cry...
One hypothesis I have is that hallucinations in a waking state, as opposed to a hypnagogic state, regardless of whether or not the hallucinations are experienced with eyes opened or closed, are linked to parallel processing. The reason that I link hallucinations and parallel processing is because pretty much all the people I've witnessed with tuppers, which were vividly hallucinated, seem to've achieved parallel processing to varying degrees.
Wow this is amazing actually besides independency one of my biggest goals with my tulpas is having them imposed so this is a win-win situation for me i will actually achieve both things with the same practise them! Actually i am already visualizing them around me in the physical world quite often because i always felt a lot of difficulty visualizing them in a wonderland, since in the physical world i don't have to worry about rendering the wonderland. Wwait a minute!! But now that you meantion... this might be a mistake i should have been trying to visualize them on the wonderland more, then, since indeed i have a LOT of trouble visualizing them in a wonderland my mind keeps flicking back between the tulpa and the wonderland (at least when i try to render a bigger wonderland).
Note that I'm only saying the two things are linked, as it may not necessarily be because of the fact the tupper is hallucinated that the parallel processing is possible, but perhaps rather that it's way easier to interact with a tupper that's tangible as opposed to one that's not, thereby making parallel processing a much more easily-achievable feat.
Tangible?? That's it, that's the main reason i want so much imposition, since the beginning i am having so much trouble finding motivation to forcing my tulpas because only seeing them as mind's eye kills a lot the feeling of having "sentient beings" and treating them as people (because i am NOT actually seeing them and i feel like "talking to air"), but i am doing my best to ignore this and force nevertheless but i never tought it would be so hard. Tell me something, is it possible to impose tulpas if we have weak visualization skills? In my case since all my tulpas are almost 100% based on actual anime characters (so far they never resisted any of this, and they demonstrated many times by their behavior and personality that they know they aren't the characters, besides most of them were even SPONTANEOUS tulpas with the exact same name, form, voice and even similar personality to the characters) it's easier to visualize them in several angles of view and i am able to watch them move by themselfs.
As for promoting hallucinations, there are the exercises in my guide and Eye-Bo, the ocular fitness program.
I think i have been having some small sucess with hallucinations when i try to visualize them HARD into a blank wall, so far i achieved a afterimage out of pure visualization (in this case pandora's head), and in other case i was able to generate a afterimage ouf of a visualized X shape, actually this reminds me, sometimes i AM able to hallucinate or generate afterimages of simple letter/geometric shapes, isn't this the same skill as imposing ? Wouldn't be logical that practising halucinating letters, numbers or simple geometric shapes would probably be faster to impose a tulpa's form as well?
Regarding eye-bo tell me something, i once had a epileptic attack when i took some specific anti-depressive medication several years ago, this only happened once and i stopped taking that medication (, is there a way to be sure if i am prone to epilept attacks because of this ? Still, i don't think i want to risk this so i will probably use the audio part of the files.
Therefore, why your tuppers choose the wrong answer some of the time may be more because of your expectations. For example, you think you might have the wrong number, so the tuppers may have the right number. I don't think there's lot of parallel thinking going on here, but rather just assumptions that "hopefully" are correct. But hey, that's just how I see it.
Actually some of the answers they give seem totally unexcepted, the problem is that it's still rare to happen, but yeah i see what you mean.
