I've been interested in personality theory on and off for a while now. Free online tests place me as INFP. However I'm also diagnosed with ADHD and I have to wonder if the cognitive deficits associated with that (poor working/short-term memory, impulse inhibition, etc.) might be causing me to behave as most Ps behave for reasons other than most Ps behave that way. In other words, maybe the neurological mechanisms that causes the average P to be spontaneous and less organised aren't the same as those causing me to be like that.
I suspect that most Ps CAN plan and remember sequences for multi-step tasks reasonably well, and they CAN think through consequences thoroughly before acting if they decide to; they just prefer not to when they don't have to. The fact that there are other ADHD difficulties not associated with Ps as far as I know, e.g. failing miserably to keep up with a continuous flow of speech even when very interested in the content, taking much longer to read anything for understanding than my reading skills predict I should, makes me tend to favour this view of ADHD as on a distinct spectrum, rather than one end of the P spectrum, in neurological and cognitive terms.
The other possibility is that the ADHD brain structure is merely an extreme (to the point of maladaptivity) version of the P brain structure. If this were the case, we would expect Ps not extreme enough for an ADHD diagnosis to perform less well than Js in the cognitive tests that help to indicate the presence of ADHD. As far as I know, no such studies have been carried out.
Regardless, my behaviour is undoubtedly P-ish (so very P-ish I've been scarcely functioning in several areas of life, hence the diagnosis) I just think it worth pointing out that it's possible that aspects of my brain structure are in fact more similar to those of Js. If P and J really do determine whether a function is 'introverted' or 'extraverted' (I'm not aware of how this aspect of the theory came into being), then it's possible that Ni and Fe are dominant for me, despite my P-ish behaviour. I don't know enough about neurological and psychological research into these traits or abilities to form much of an opinion either way. I know quite a lot about findings regarding the ADHD brain and cognitive profile, but not about any looking for differences between different kinds of people within the healthy range of these behavioural/cognitive spectra. If anyone knows any, I'd be glad to hear of it, as it would be the best way I can think of to settle the issue.
Anyway, I am finally receiving some appropriate help to become independent and make use of my talents and my main goals for the future are getting things published and starting a career in learning support (student mentoring, note-taking, proofreading, things like that).
Other than that, I guess I'll just say hi and offer to answer any questions.
