The functions contained in table 2 can be qreatly extended in number and content. One miqht wish to add special rules for interaction between :parent ,'and Child, spouses, and among members of the same age'group, etc., plus a mechanism for determining the birth and death of various members. The status factor might be divided into weights refering to social status, aqe, geographical proximity and the like. The ideal test of the validity of a simulation is prediction. Hopefully, one miqht predict an attested state of a language from a model of an attested earlier stage. A major problem in such testing may be i i~.xlreme sensitivity of a model to the choice of parameter values and constants. For example, the constants in the functions of table 2 seem to have the effect of making BABY learn too quickly. One might use a higher rate of decay for unused Klein 15. rules to decrease the learning rate. The need for trial and error manipulation of values will increase with the complexity of a model. Accordingly, one might start with simple models, increasing the complexity by stages. The author's immediate research goal is to produce a stability simulation involving about 50 members,each associated with a simple phrase structure gra~nar of ~ ~nqmish, over a time span of 3 or 4 qenerations--a simulation in which the language at the start of the simulation is reasonably similar to the language existing at the conclusion.",
