Would a Ring of Mind Shielding defeat detect anxieties / detect desires?

[Alzrius]

So the description for the ring of mind shielding says that it defeats detect thoughts.

My question is if this extends to spells that "function as" detect thoughts, such as detect anxieties and detect desires. While a strict textual interpretation would seem to say no, I have to wonder if the wording indicates that they're similar enough that they'd also be defeated by the ring.

[Volkard Abendroth]

I would say yes.

Both of those spells state that they function as Detect Thoughts.
