Memory Book

I read it here:

Here is an excellent review by my academic advisor's academic advisor:

Disclosure: I am a memory researcher and book is of particular historical interest for me. I thought the 1913 translation was great; it's easy to see why it has stood the test of time, with multiple reprints in the 21st century. This guy was unbelievably prescient and he would be pleased to see the course that modern science has taken because it is so like his own conception of it. A true pioneer of social science research, quantitative psychology, and experimental design, Ebbinghaus sounded eerily modern throughout. His ideas and discoveries abound in such a way that you are left wondering what memory researchers have been up to for the past 150 years! In this book, he either postulates or hypothesizes about lots of big ideas, many of which still provide reliable fodder for research programs today: the testing effect, the spacing effect, connectionism, the learning (and forgetting) curves, mathematical modeling of psychological phenomena, the serial position effect, observer-expectancy effects, blinded experimental designs... Not only that, but he treats several of them as if they were old ideas or so much common sense. The ending was abrupt, but hey: it's a translation of a scientific monograph from the 1880s after all. Still, it was eminently readable, particularly for those already inured to reading the results sections of scientific journals (the received tradition of which Ebbinghaus appears to have influenced in the way he organized and reported his results, evaluated his hypotheses, and discussed the implications of his findings). His rigorous self-experimentation is an important precursor of the quantified-self movement, with people like gwern now bearing the standard and carrying on Ebbinghaus' lofty legacy (eg., ).
