In two previous papers we examined the measurement characteristics and the sensitivity of the method of paired comparisons as a scaling approach to representative child incenrives employed in recent experimental investigations (Witryol & Fischer, 1960; Witryol & Ormsby, 1961). Our results have demonstrated that Ss, ranging in age from 3 to 12 yr., can scale these incentives quite reliably and that the rank positions of these reward values are consistent with equivocal results from reinforcement laboratory learning research with children. On the basis of certain surprises encountered when we conducted a developmental scaling research, e.g., the strong potency of verbal incentives in older age groups, and in response to one laboratory accident (unintentionally allowing a group of preschool Ss to play with one reward object), we began to reconsider the more obvious determinants of incentive value, i.e., inuinsic and extrinsic conditions. It can be assumed that commonly used laboratory incentives, like candy and uinkets, possess intrinsic edible and manipulatable reinforcement strength for children. But Ss in recent experiments on incentive valences have usually been at least 3 yr. of age, and even at that early developmental level, exrrinsic, derived reward values must be assumed to have been superimposed upon primary reinforcement strengths as a function of learning, more or less homogeneous for cultural groups. This involves the familiar process of secondary and higher order reinforcements. The child psychologist studying incentive strengths very often encounters secondary reward values already built into the history of his young, contaminated Ss. One line of investigation which then ensues would deal with the susceptibility of intrinsic rewards to the influence of excrinsic or secondary reinforcement values. The basic hypothesis is that incentive object preferences of preschool children are strongly influenced by social suggestion or social learning. The purpose of the study was to demonstrate that a relatively neutral object, judged lowest on a scale by young children, would subsequently be rated higher after verbal social manipulation.
