Predictions from rccent transfer hypothesis (H) for reversal (R) and extradimensional (ED) shifts were tested directly using conjunctive concept identification problems. To assess a hierarchical probability of sampling of Hs within or across domains, four transfer conditions (R-1, R-2, ED-I, and ED-2) were arranged according to complete or half change in values or dimensions. The transfer performance was rank-ordered as follows: R-1≒R-2>ED-l >ED-2. These results were attributed to the fact that the subject first samples Hs within the previous correct domain, at the start of transfer, then tests some domain which differs in a single dimension from the training domain, and finally chooses Hs from other new domains with two changes in dimension.
