Confabulation - ANS ✔✔A behavior in which individuals, when asked to remember past events,
respond with highly detailed but false memories; associated with some forms of amnesia.
Ribot gradient - ANS ✔✔A pattern in which retrograde memory loss is worse for events that
occurred shortly BEFORE the injury than for events that occurred in the distant past.
*Patients with bilateral medial temporal lobe damage generally show some retrograde amnesia
along with their anterograde amnesia.
Frontal Cortex - ANS ✔✔The regions of cortex that lie within the frontal lobes and that may play
a role in...
1) Determining which memories are stored vs not
2) Producing metamemory for that information.
3) May help us determine the "source" of our memories
4) May help us determine if a memory is "real"
Declarative (Explicit) Memory? - ANS ✔✔- Conscious, effortful recall of information and
experiences
- Can typically be verbalized
- Two types: Episodic and Semantic
Semantic Memory - ANS ✔✔- "I know"
- Can be general knowledge, info, facts or personal information
- Context free (x attached to specific time or place)
- Can be learned in a single exposure and also strengthened by repetition
, Episodic Memory - ANS ✔✔- "I remember"
- Specific events + personal experiences
- Temporal and spatial attachments (aka mental time travel, autonoetic consciousness)
- Learned in a single exposure/can be weakened by exposure to similar events
Retrograde Amnesia - ANS ✔✔Point: can't remember OLD memories.
- Loss of memories learned BEFORE the brain damage.
- Episodic memory from before impaired, Semantic memory intact
Anterograde Amnesia - ANS ✔✔Point: NEW memories affected.
- Not being able to acquire new memories AFTER the brain injury.
- Episodic memory impaired; semantic memory from before injury intact but semantic
knowledge from after injury impaired.
Intact memory? - ANS ✔✔Memories from before the brain injury event, always involving
semantic knowledge.
Two views on the Relationship between Semantic Memory and Episodic Memory? - ANS
✔✔View A: Episodic memory grows from Semantic memory.
- i.e. you have to know what a graduation ceremony is in order to remember it.
View B: Semantic memory grows from Episodic memory in that semantic memory represents
info we have encountered repeatedly
- i.e. specific episodes blend together to form a strong semantic memory
Do nonhuman animals have episodic memory?
