Halford et al. (2010) claims discusses binary relations and that humans can process up to a quaternary relation. Are these equivalent to "0-dimensional," "1-dimensional" relational reasoning problems discussed elsewhere?
For example, a binary relation discussed in that paper, taller(Bob, Tom) involves comparing one dimension: height, so it could be a 1-dimensional problem, yet I can't find confirmation of the terminology.
