Once we begin to disengage from the arbitrariness inherent in arbitrary metaphors, and rely on what actually generates memories (action-neural-spatial-syntax), we can study what's really happening in the allocortex's distribution of cues between sense/emotion into memory.
Until then we will simply be trapped in falsely segregated ideas of episodic/semantic.
I can recall the experience of getting in on a cold morning, pumping the throttle pedal three times to activate the semi-automatic choke, starting it, and getting out to clear frost off the window while it warmed up a little. The tactile feeling and squeak of the throttle linkage, the sound of the starter motor, the hollow sound of the door closing, and the noxious exhaust from the cold start (which I haven't smelled in 30 years). I remember how my little plastic window scraper sounded when scraping the glass, and even how the defrost vents made two regions which were always easier to scrape. But, I cannot really remember a specific episode of this on a certain date or leading to a particular trip.
On the other hand, I do have an episodic memory on my final trip in this truck. It was sliding off an icy road, rolling over, and sledding down a steep slope. I remember the ruptured, snow-filled windshield, and the sound of the engine idling upside-down. I remember the slow motion way the whole crash unfolded, and the clothes I was wearing as I crawled back to the roadway.
Ironically, I have more emotional context with the generic cold-start memory. It brings with it some vignette of teenage eagerness and pride in having this vehicle and the freedom it represented. The crash is more dissociated, a movie I was watching from within myself. I can meta-remember that I was very distressed afterward, but those feelings are not connected with the memory during recall.
This is very interesting to me. I have temporal lobe epilepsy. My episodic memory is quite poor. However, I believe I'm fairly good at learning new facts (i.e. semantic memory). Perhaps my belief is an illusion, or I'm really only learning facts when my episodic memory is less impaired (which happens; it varies from hour to hour). It's difficult for me to tell of course.
