Just thought I'd mention this: as a child, I detested praise. (I'm guessing it was too strong a stimulus, along with such things as asymmetry, time being a factor in anything, and a mildly loud noise ceasing.) I wonder how it's affected my overall development.

Incidentally, my childhood dislike of asymmetry led me to invent the Thue-Morse sequence, on the grounds that every pattern ought to be followed by a reversal of that pattern.
