Older adults cannot be trained to use memory strategy.

Frage 4
Frage
Which of the following statements is not correct?
Antworten
-
The ability of patients (such as H.M.) to learn new motor tasks despite an anterograde amnesia has be taken as evidence for multiple memory systems.
-
Declarative memory is representational, thus, it can be true or false.
-
Declarative memory is expressed through performance, e.g. improvements in tasks like mirror drawing.
-
Memory systems operate in parallel.
-
Our memory is reconstructive, thus, it is influenced by our knowledge, experiences and expectations.
