Designation refers to the ability of productions to call for thl' crl'ation of neow productions . Strengthening a production involves adjusting the amount of system reaources that will be allocated to its proct'ssing. Finally, gc.-noralizalion and discrimination refer to complementary processes that produce better performance by either extl'nding or restr icting the rangto of situations in which a production will apply.
