About this exercise
Word-pair recall (a paired-associates variant) is a classic episodic memory paradigm dating to Ebbinghaus (1885).
You see N pairs during a fixed study window, then are tested by being shown one word and picking its partner.
Mental imagery — picturing the two items interacting — produces a 2-3× recall boost over rote rehearsal.
Used in clinical neuropsychology to detect early hippocampal changes.
