Is there a single notion in the cognitive sciences for "unconscious memory"? For example a in a 2015 Northwestern University press release, we find that
- Scientists retrieve unconscious memories
- Could lead to new treatment for patients with repressed traumatic memories
On the other hand, in a different area of research we hear that
The brain’s unconscious memories of patterns are likely to be partly responsible for some children struggling to learn to talk.
So how many (sufficiently) different notions of "unconscious memory" are there in the (contemporary) science literature?
