Different. Of course, IMC Psionics are extraordinarily rare, there's maybe 100 psionically active people, and they're all nobles of one particular nation (a long running breeding program by the Undying King led to the emergence of this "Mental Magic".) And they're all human.
That said, energy resistance is energy resistance, and anything with an energy descriptor cuts across the boundaries to some degree. Resistances function normally, as does "Quench" (since it just kills fire), but counterspelling is a lot harder, and dispel/nullify are very different.
There's only one Use X Device skill, but Knowledge (Psionics) and (Arcana) are different, as are Psicraft and Spellcraft.
