# ORDINAL RELATIONS AND TRANSITIVITY IN MENTAL RETARDATION

## Abstract

This revised proposal requests support for a three-year study of stimulus
control and transitive processes in mentally retarded individuals'
discrimination learning.  The project seeks to clarify learning processes
involved in the formation of stimulus classes defined by ordinal stimulus
relations (i.e., sequence classes).  Comparisons of several training
methods will identify behavioral histories that lead to acquisition of
ordinal relations that are also transitive.  Our primary concern is to
determine whether new ordinal relations will emerge without direct training
via transitive relations among sequence-class members.  We expect to show
that, given appropriate learning histories, transitive performances are
demonstrable in persons functioning at much lower developmental levels than
generally thought.  We also expect to demonstrate that the behavioral
processes to be investigated are formally similar and highly relevant to
those involved in acquisition of rudimentary academic behaviors, such as
arithmetic and money skills.  Our research is likely, therefore, to
contribute to a growing technology for teaching mentally retarded people
and others with special instructional needs.
