PARENTAL BEHAVIOR 



1359 



has found that monkeys so reared failed to 

 develop sexual behavior at the normal time, 

 that they do not become capable of playing 

 with other young monkeys, and that they 

 remain attached to the "mother" for a very 

 much longer time than do normally reared 

 monkeys. Apparently some aspects of the 

 behavior of the real mother toward the in- 

 fant, which play a crucial role in the de- 

 velopment of various aspects of the be- 

 havior of the young, are lacking in the 

 artificial "mothers." 



From this small sampling of a very large 

 body of research, it is apparent that the 

 behavior of parents toward the young, both 

 in birds and in mammals, plays an impor- 

 tant role in permitting and, to various ex- 

 tents in different kinds of animals, in guid- 

 ing the development of the behavior of the 

 young in their response to hormonal stimu- 

 lation and in their integration into relation- 

 shijis with other members of the species.
