Question

Which of the following about amnesia is TRUE?

a)Psychogenic amnesia is more common than organic amnesia.
b)Anterograde amnesia is the inability to retrieve explicit information prior to trauma.
c)Retrograde amnesia is oftentimes temporally-graded.
d)There is no reported case where a person suffers from both retrograde and anterograde amnesia.

Answer 1

The true statement about amnesia is that 'Retrograde amnesia is oftentimes temporally-graded.' This reflects the pattern of memory loss where more recent memories are less accessible than older ones in individuals with retrograde amnesia.

Step-by-step explanation:

The true statement about amnesia is c) Retrograde amnesia is oftentimes temporally-graded.

This means that the loss of memory for events that occurred prior to the trauma often presents more profound memory gaps for recent events than for more remote events.

The likelihood of retrieval increases for events further back in time.

Retrograde amnesia involves difficulty remembering episodic memories, such as personal experiences and events.

Option b) Anterograde amnesia is incorrect because anterograde amnesia is characterized by the inability to form new memories after the occurrence of trauma, rather than an inability to retrieve memories prior to the trauma.

Cases like H.M.'s illustrate this condition, where an individual is able to learn tasks through repetition despite not consciously recalling prior practice sessions.
