Behavior/psychology

Famous quotes containing the words behavior and/or psychology:

“The fact that behavior is “normal,” or consistent with childhood development, does not necessarily make it desirable or acceptable...Undesirable impulses do not have to be embraces as something good in order to be accepted as normal. Neither does children’s behavior that is unacceptable have to be condemned as “bad,” in order to bring it under control.”
