Any research on right-hand/left-hand based preferences when interacting with an interface? My original question is "Left or right placement of interactive elements on a web page", but only now did I find a place where I think I can find the right people to understand it.

The gist is: is there any natural inclination in right-handed people, when reading a web page, for example, to prefer those interface elements which lead to actions (e.g. "print", "save", "get a link", etc.) to be placed on the right side of the screen and then, to prefer navigational elements (e.g. menus, especially tree-structured category menus) to be placed on the left side, while the preference for content for reading would be in the middle? 

That is: navigation (reference stuff) on the left, content (passive perception stuff) in the middle, action elements on the right, all in this manner because of a potential instinct to reach for anything action related with one's right hand.

Is there any research or at least speculation on the subject?

And a follow-up question: if there is such an inclination does it appear to be reverse in left-handed people?

There is indeed some research on handedness and user interfaces but not exactly at the level you seem to be after. Handedness matters for tablet interfaces, hand occlusion is a particular concern there.

Some references: http://hal.inria.fr/hal-00670516/en and http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.89.4546

Speculating myself a little bit, I would however be careful when drawing practical conclusions from any putative “natural” handedness-related inclination. Maybe there is such a thing and it could conceivably be measured but you need much more than that to justify any UI decision.

In particular, cultural factors (in a broad sense, including web and platform conventions) could just as well play a big role. The usability literature has always emphasized consistency and the fact that your interface is just going to be one of many interfaces with which users are regularly interacting so when in doubt always try to follow common practice, not necessarily because it is better as such but simply to avoid confusing your users. In any case, there is no reason to worry specifically about “natural” inclinations (as opposed to learned ones).
