College students were trained on a conditional discrimination under one of the two types of instruction, and then were given intradimensional (ID) or extradimensional (ED) shift problem. When Ss were given the instruction that emphasizes the connections between conditional cues and stimulus values, no significant difference was obtained between ID and ED shifts. And when Ss were given the instruction that emphasizes the connections between conditional cues and stimulus dimensions, ID shift was learned significantly faster than ED shift.
