Thus, excess frustration will increase proportional to the increase in m- For 

 this reason, animals will always be conservative in that they will attempt 

 to reject any changes leading to an increase in fj..

In some circumstances n may be more labile than i as an adjust! ve mecha-

 constant at that level appropriate to Nb, a remains ab. And yet Eq. (55) 

 reveals that the N differing from A^6 can become No provided:

In the original change of No from Nb, m and /x' were //& and nb and each 

 was therefore equal to 1.0. However, we are here concerned with the case 

 when n is labile, that is, it can become different from /xb. Furthermore, 

 fib can be ignored since any change in fib must await some stability in the 

 change of fx. Thus, when a remains at ab
