Title: '...All Except...'.Definition by Exclusion, Relative Class Complexity and S-R Compatibility in Dichotomous Classification Tasks.
Authors: Shepherd, R. D.

Subjects: Social classes, Class differences, Class identity, Families, Education, Sociology
Abstract: The article reports that if a family of items is divided into two mutually exclusive classes it is economical to define the more complex class in terms of the less complex one. For the purpose of this experiment the 'complexity' of a class is defined in terms of the number of discriminably different members included within it. The 'relative class complexity,' or ratio, of two classes is the number of members in the smaller class to the number of members in the larger class. As the ratio of the complexity of two classes approaches unity any advantages of definition by exclusion should diminish; At some ratio less than unity the advantages of definition in terms of the less complex class should be balanced by the disadvantages of definition by exclusion. These considerations only apply when a response is to be made to the members of one class but not to members of the other since if both classes are associated with their own response the instructions can always be transformed in such a way as to allow the subject to work in terms of the least complex class defined by inclusion.
