Recent essay arguing against the categorization of mirrored sensory experiences as synaesthesia

Synaesthesia researchers Rothen and Meier argue that "mirrored sensory experience" or mirror-touch synesthesia is not synaesthesia. If you have an interest in the theories about "mirror-neurons" and empathy, or the debates on these themes, you might find this piece of interest. In past posts I have criticized these researchers, but I'm inclined to agree with them on this point.

Why vicarious experience is not an instance of synaesthesia.
