This question seemed to raise more questions than answers! (Incidentally I have been deluged with interesting answers and theories in response to both of my recent questions so please forgive me if you are not quoted!). I have not yet had enough time to read any of the references so I am still not sure what a meta-analysis of the research would conclude. I am beginning to wonder if will ever have enough time to read all of the references. If anyone does (preferably someone who is a polyglot and speaks at least English and German!) have enough time please let us all know what you conclude!

Here are some of the more interesting responses:

2. Kate Morgan (University of Strathclyde Bioengineering):

Figure skaters have a tendency to spin to the left if they are right handed and vice versa (although there are exceptions) you might want to do a literature search in some sport journals to see if there's any information there.

3. Jos Vanrenterghem (Research Institute for Sport and Exercise Sciences, Liverpool John Moores University)

I have been working with older adults (60 years of age). Many of them have reported that they became ambidextrous or changed chirality after a certain event in their life. Particularly injuries seem to be the cause of that. Also, there is often a difference in chirality between hands and feet, which can sometimes be explained, but often further analysis is required to find the underlying mechanism of this.

4. Robert Schleip (Ulm University, Germany):

On the left-spin in humans: The book "Der Linksdrall in der Natur"(i.e. the left-spin in nature) by the biologist Siegfried Wachtel, mentioned in that article, has unfortunately not yet been translated. But Onur Gunturkun has published a few papers on hemispheric asymmetry.
