“22 chronic psychotic patients, Ss in an operant conditioning study, were given psychological tests and rated as to their ward behavior. Ratings of ward behavior and rates of operant response were directly related. Those patients who were testable by at least one clinical test were those who were high operant responders. These findings were discussed in terms of a notion of adaptability to the demands of the hospital environment. Clinical and operant data on 6 normal Ss were also presented.” (PsycINFO Database Record (c) 2006 APA, all rights reserved)
