Which of the following statements most closely describes "Ribot's law"?
Electroconvulsive shock therapy selectively disrupts the oldest episodic memories.
Anterograde amnesia is temporally graded; while it is difficult to form new declarative memories at first, memory formation fully recovers in most anterograde amnesia patients.
Retrograde amnesia is temporally graded, and recent memories are more likely to be lost with brain damage.
There is a double dissociation between retrograde amnesia and anterograde amnesia.
