ABSTRACT
This chapter consists of a series of related experiments using subnormal subjects. It is written for psychologists engaged in research in subnormality and those concerned with the experimental psychology of memory. It is important to realise that research can take many forms, and serve a variety of purposes. A project may need to begin in the 'laboratory', leaning heavily on models, theories and techniques derived from experimental psychology. It can then develop in a more applied direction without sacrifice of rigour or objectivity by applying or translating research findings in the classroom, the hospital ward or in the home situation. Motivation for an experimental task as an end may be different from motivation for a task to which memory is a means. It should be stressed that organisation is seldom optimal; subjects seldom recall precisely in the order imposed on the material by the experimenter.
