One other thought occurred to me as I looked through Coren's book. In addition to a dominant hand and a dominant foot, people have a dominant eye, which may be involved in the direction a person spins when skating. Furthermore, "eyedness" is correlated with handedness:
"Like handedness, eyedness is mostly a right-sided matter in human beings. Our survey showed that 71 percent of the population is right-eyed. Also, 74 percent of human beings have their dominant hand and their dominant eye on the same side...." (p. 30) The idea that eyedness is important for the direction of spin is supported by the following observation: "Judgements of direction are also affected by eyedness. When asked to locate a position in space that they think is 'straight ahead' of them, people tend to pick a position shifted toward the side of their dominant eye. The visual system seems to interpret 'straight ahead' to mean 'straight ahead of your dominant eye'." (p. 31) Jeff Reference: Coren, S.
