“Computer” as a metaphor
for memory and information processing.
Also interference, distortions, consolidation problems, other phenomenon
If you study a list of words/concepts, then immediately try to recall them, you get “Primacy” and “Recency” effects.
With delayed recall, you get only the “Primacy” effect.
Primacy Effect: early items are transferred to LTM (fresh task)
Recency Effect: items studied w/in last seconds are still in STM, if immed test
Intermediate items were not encoded strongly into LTM, also not now in STM

Hermann Ebbinghaus (1850-1909) conducted the first systematic studies of human memory. Using himself as a subject, he learned nonsense syllables, then tested his memory after delays up to 31 days.
Most forgetting occurs rapidly, then what “sticks” tends to stick long term.
