5 classic studies of learning

I have a piece in the Guardian, ‘The science of learning: five classic studies‘. Here’s the intro:

A few classic studies help to define the way we think about the science of learning. A classic study isn’t classic just because it uncovered a new fact, but because it neatly demonstrates a profound truth about how we learn – often at the same time showing up our unjustified assumptions about how our minds work.

My picks for five classics of learning were:

Bartlett’s “War of the Ghosts”
Skinner’s operant conditioning
work on dissociable memory systems by Larry Squire and colleagues
de Groot’s studies of expertise in chess grandmasters, and ….
Anders Ericcson’s work on deliberate practice (of ‘ten thousands hours’ fame)

Obviously, that’s just my choice (and you can read my reasons in the article). Did I choose right? Or is there a classic study of learning I missed? Answers in the comments.
