This experiment presents 3 prototypes, then asks participants to identify them. Once they have classified minor distortions of them for two consecutive sets of practice trials, they are asked to classify some more major distortions. They classify distortions as either new or old based on whether they saw them in the practice trials.

Previous work has shown that Ss can learn to classify sets of patterns which are distortions of a prototype, even when they have not seen the prototype. In this paper it is shown that after learning a set of patterns, the prototype (schema) of that set is more easily classified than control patterns which are also within the learned category. As the variability among the memorized patterns increases, so does the ability of Ss to classify highly distorted new instances. These findings argue that information about te schema is abstracted from the stored instances with very high efficiency. It is unclear whether the abstraction of information involved in classifying the schema occurs while learning the original patterns or whether the abstraction process takes place at the time of the first presentation of the schema.
