Research is still ongoing, but I thought I'd share a useful lua script I wrote for dfhack based on the one by Nilsolm.
-- Prints out all the memories of the selected unit, along with some metadata.
local help = [====[
Select a unit in dwarf fortress, then run this script.
It will print out three blocks of information:
Short term memories, long term memories, and memories which have been
reflected upon.
The number in brackets after the thought is metadata used to store extra
details about the type of memory. It tracks things like who was talked to,
which book was read, etc.
The strength variable probably determines which memories get overwritten.
The severity variable seems to store metadata such as the value of a room
or the quality of an tem of clothing.
Memories in the "reflected memories" category don't seem to cause new
thoughts, but any personality changes which resulted from those memories
are displayed.
The date format is "YYY-MM-DD HH:TT", where TT runs from 0 to 50.
There are 50 ticks per hour so this seemed more elegant.
Options:
-help show this help screen
-all include overwritten and uninitialized memory slots in the output

This should display all the memories of a dwarf, even ones which aren't present in their thoughts page. It also lists a non-zero strength value for every memory, although I'm still not 100% sure how those are calculated or how they relate to stress.
If the colours look weird in your terminal, try changing the color_A and color_B values.
Interestingly a lot of my dwarves seem to have very few long term memories and many even have empty slots in their short term memory. It explains why my strategy of trying to fill up their long term memories with positive thoughts wasn't working. Memories get removed from long term memory much faster than I had previously believed.
It shows a lot of "ANYTHING due to None" emotions. I don't know what those are about, but the rest seems to be accurate.
Those seem to be leftover data from memory slots which have been cleared. The game overwrites the emo.type and emo.thought fields with -1, but leaves all the other data in place.
I added a check to my script to filter them out since they don't provide much useful information and can be confusing.
EDIT: Added an -all option to the script which will display the contents of the cleared/uninitialised memory slots.
