Performance-acquisition of relational discrimination of the greener member of pairs of hues from among four blue to green hues and from among four yellow to green hues was related to presence or absence of instructions to choose the greener member of a pair crossed with presence or absence of information about correctness of choice. The Ss were younger (X = 49 months, N = 32) and older (X = 63 months, N = 32) white middle-class boys and girls from among those then attending a private suburban nursery school. Through 48 trials under the four combinations of instructions and information, the relational discrimination was most complete or acquired fastest with instructions to choose the greener member, regardless of presence or absence of information. Relational discrimination was less complete or acquired less rapidly with information alone, and did not occur in the absence of instructions and information.
从四种蓝色到绿色色调以及从四种黄色到绿色色调中对更绿色的一对色调成员进行关系辨别时，表现（习得情况）与是否有选择一对中更绿色成员的指示以及是否有关于选择正确性的信息有关。被试是当时就读于一所私立郊区幼儿园的白人中产阶级男孩和女孩，年龄较小的（X = 49个月，N = 32）和年龄较大的（X = 63个月，N = 32）。在指示和信息的四种组合下进行48次试验，无论有无信息，当有选择更绿色成员的指示时，关系辨别最完整或习得最快。仅靠信息时，关系辨别不太完整或习得较慢，而在没有指示和信息的情况下则不会发生。
