The aim of the present study was to examine whether a rating-based procedure that has already been used by other investigators can be used for derivation of typicality ratings from children. The evidence reported in the study establishes that such a procedure cannot be reliably used for this purpose. The results show that children rated category items in terms of personal preferences rather than as a function of how representative they considered the items to be of their superordinate category. On the basis of these findings, an alternative method based on the family resemblance scores of the category members was proposed in order to derive typicality ratings from young children. This family resemblance method of obtaining typicality judgments may be useful to investigators interested in assessing how children process categorical information.The method widely used by investigators (e.g., Rosch, 1973Rosch, , 1975 to derive typicality ratings requires subjects to judge the degree of typicality of a particular category member on the basis ofa rating scale. Normally, subjects are asked to rate items according to a 7-or 6-point scale, ranging from 1 for very good category members, through 2, 3, 4, 5 for quite good,fairly good, good, and poor, respectively, to 6 or 7 for very poor category members.It is not possible to employ such a rating task with very young children as subjects; the linguistic and cognitive demands of the task are too difficult. Previous investigators have, however, used 3-point rating scales to derive typicality ratings from children in a playful context (see Bjorklund, Thompson, & Ornstein, 1983). In this study, children were asked to rate category items in order to help a person from another planet understand the meaning of the categories. The task required the children to rate the items on a 3-point scale in a playful context. Three schematic faces, each having a different expression, were presented to them. The children were told to rate the items while pointing to one of the schematic faces. The "smiling" face corresponded to "very good" category members. These members would be very helpful to the spaceman for understanding the category. The "straight" face corresponded to "okay" category members. These members would help the spaceman somewhat to understand the category. The "frowning" face corresponded to "poor" exemplars, items that would not help the spaceman understand the category very well. The children were instructed to rate the items in terms of how good an example each item was of its category and not in terms of how much they liked the item.
