How the difficulty of initial training influences the acquisition and trans
fer of strategic processing skills and memory for processed stimuli was exa
mined in 3 experiments. Participants were asked to discriminate between sim
ilar or dissimilar random polygon stimuli. Participants were asked to discr
iminate between novel transfer polygons; this was followed by a recognition
memory task. Results suggest that the difficulty of initial training influ
ences strategic skill acquisition. Strategies acquired during training are
applied at transfer regardless of their effectiveness for processing transf
er stimuli. This is true even when participants are given feedback indicati
ng that their processing strategy is ineffective. It is argued that skill a
cquisition is influenced by the acquisition of both stimulus-specific knowl
edge and strategic skills, and that the strategic skills acquired serve to
optimize processing.
