Not my claim, what I am saying is that as long as there is a physical connection between these domains we can’t be surprised about universal representations. In a spatial Fourier transform, spiky things have high frequency information. In a time Fourier transform, spiky sounds have high frequency information. In space, spiky things have sharp edges (attack). In time, sharp sounds have faster attack. The presence of a physical analogue here means that all these experiments are testing is whether brains identify this existing connection.
It would be more surprising if the connection was indicative of genuine universality of brains and their representations, rather than ability to identify a cross-domain mathematical/physics-cal connection.
