the neural mechanisms that underlie Aspergers and the formation of type may very well be interrelated, especially considering the intergrated nature of the brain. in the case of AS, abnormalities such as reduced connectivity are broad reaching - they affect the entire neural network, so it stands to reason that AS is going to have an effect on the development of personality.
if aspergers sufferers appear to resemble certain types but not others (as they indeed do), it is not unreasonable to conclude that the AS condition predisposes individuals to certain functional profiles/types. whether model A manifests in AS individuals in the same way as it does in neurotypicals is unclear (probably it doesn't). i speculate that there are differences in the interaction between functions as individuals develop (reduced interaction perhaps, with certain functions impaired to begin with). repeated failures in social situations as a result of AS may cause individuals to become socially isolated. this, along with other environmental cues associated with AS may in turn also have an affect on the strength and ordering of various functions.
that AS sufferers use some functions better than others seems to be the case when we examine their behaviour/functional differences. they can be remarkably good at pattern recognition, logical deduction, and understanding complex systems (Ne, Ti); some have semi-photographic memories and heightened vision/hearing/smell etc (Si?, mentally manipulating visual objects). but generally all are poor at recognising emotional and cognitive states in others according to non-verbal cues (Fi) and expressing their own thoughts and feelings in a socially appropriate manner (Fe). to give a concrete example of this, a conversation with an AS friend:
friend: so what are your plans for tomorrow?
me: i have to take my mum to see a lung specialist actually. she's been coughing a lot lately, and we're afraid it might be the beginning of lung cancer that could have spread from her breast cancer. she's just had radiotherapy.
friend: oh, fair enough.
individuals with the visual subtype of AS (the above friend is an example) have a weakened ability to abstract. for instance, they cannot do algebra since they have great difficulty comprehending that the letters stand for numbers. this seems to imply directly weakened Ni and Ne. a direct result of this weakened ability to abstract is that for such individuals to be aware of an object/person/event/situation, that thing/person needs to be in the AS sufferer's physical presence. in other words, they have an impaired ability to imagine what they have not experienced. and what they do not experience repeatedly or continuously, they will forget/fail to recall/keep in mind. this means that they cannot imagine scenarios that are verbalized to them in the same way that neurotypicals can. in the above conversation, my friend does not recognize what i must be thinking/feeling in my situation because he has never been through that situation before. he cannot and does not imagine it, and as a result, he does not empathize or sympathize as a neurotypical would. this isn't to say that he's a bad guy. he's a great person, with a big heart and a lot of love to give, but he just isn't great at 'cottoning on' to what the other person's thinking or feeling.
