Strategies and classification learning.

How do strategies affect the learning of categories that lack necessary and suf-ficient attributes? The usual answer is that different strategies correspond to different models. In this article we provide evidence for an alternative view— Strategy variations induced by instructions affect only the amount of information represented about attributes, not the process operating on these representations. The experiment required subjects to classify schematic faces into two categories. Three groups of subjects worked with different sets of instructions: roughly, form
