Err, no. Somebody pointed out in #wrongplanet (sorry, I can't remember who) that "obsession" is a largely misused word, especially in the AS community (for obvious reasons - so many of us *have* these "encompassing preoccupation[s]"). To put it briefly, an obsession must be either unwanted or unreasonable according to the majority of the definitions I've read. MSN's Encarta dictionary defines it as a "preoccupation" alone, and Merriam-Webster concedes that when taken "broadly", it can mean "compelling motivation", but it seems by most definitions that that's too broad.
Definition from dictionary.com:
Quote:
ob·ses·sion
n.
1. Compulsive preoccupation with a fixed idea or an unwanted feeling or emotion, often accompanied by symptoms of anxiety.
2. A compulsive, often unreasonable idea or emotion.

Dictionary.com's results for "compulsive" are
extremely unuseful, so let's head straight to
Wikipedia to get its definition of both terms.
Here's Wikipedia's definition of "obsessions" within the context of
obsessive-compulsive disorder (note: all of these characteristics combine to define "obsessions"):
Quote:
1. Recurrent and persistent thoughts, impulses, or images that are experienced, at some time during the disturbance, as intrusive and inappropriate and that cause marked anxiety or distress.
2. The thoughts, impulses, or images are not simply excessive worries about real-life problems
3. The person attempts to ignore or suppress such thoughts, impulses, or images, or to neutralize them with some other thought or action
4. The person recognizes that the obsessional thoughts, impulses, or images are a product of his or her own mind
And "compulsions":
Quote:
1. Repetitive behaviors or mental acts that the person feels driven to perform in response to an obsession, or according to rules that must be applied rigidly.
2. The behaviors or mental acts are aimed at preventing or reducing distress or preventing some dreaded event or situation; however, these behaviors or mental acts either are not connected in a realistic way with what they are designed to neutralize or prevent or are clearly excessive.
Clearly, this isn't something that's unwanted or distressful.
So, how should this be described, then? Um... Gee, I don't know. This person I speak of suggested "perseveration", but when I looked up this definition, it didn't seem to fit. How about just "preoccupation"? That's what it says in the DSM-IV criteria for Asperger's ("encompassing preoccupation ..."). In this case, perhaps "repetitive preoccupation"?
