This study is intended to yield information about the type of task that a chronic schizophrenic might be expected to succeed at and, conversely, the conditions under which their disabilities are magnified. The primary purpose is to obtain data to act as a guide in the design of work for such patients, and secondly to produce more general information about the differences between the normal person and the chronic schizophrenic on sequential operations. The task studied involved primarily both long and short-term memory functions, together with the associated processes of attention.
