幼児の非次元性刺激による逆転・半逆転移行学習

抄録

To examine the preschooler's learning mode, performance on reversal shift (RS) was compared with that on half-reversal shift (HRS) using unrelated stimuli of familiar objects. In RS all the sorting responses in the original learning were reversed and in HRS only half of them were reversed. HRS tended to be learned faster than RS, and evidence of independent subproblem learning was obtained through subproblem analysis. These results suggest that the preschoolers learn in single-unit S-R mode. However, the difference between HRS and RS was statistically insignificant and some Ss showed spontaneous reversal on HRS-unchanged items. All children at this age might not learn equally in single-unit S-R mode but some might learn in mediational mode.
