Abstract
Reversal (RS) and extradimensional (EDS) shift groups were subdivided into undertrained (UT), criterion trained (CT), and overtrained (OT) conditions. Results indicated: (1) The RS was learned faster than the EDS in both the CT and OT conditions, but Ss in the UT conditions did not differ. (2) Ss in the UT condition took longer to learn the RS than Ss in either the CT or OT conditions, but no significant difference was found between the CT vs OT conditions. (3) The EDS group did not differ significantly with training level. The ORE was demonstrated, but the hypothesis that this ORE might be explained in terms of the increased awareness of incidental cues which has been found in OT was not supported.
