Doxycycline is a semi-synthetic tetracycline antibiotic prescribed to treat various bacterial infections such as urinary tract and bladder infections. Veterinarians also use Doxycycline to treat some diseases such as Rocky Mountain Spotted Fever and Lyme disease.
Habituation is actually a good thing; it indicates that the child is learning. For example, when there's a loud noise, Parker is startled and looks at whatever makes the noise. He is scared that the loud noise might mean danger.
This can be contrasted with habituation, which involves disassociating a stimulus with a particular event and a decrease in response behavior (Gleitman, 1992). Perhaps the best example to demonstrate the principles involved in classical conditioning learning are the experiments carried out by Ivan Pavlov. Pavlov noticed that when he presented his dogs with food, this unconditioned stimulus (UCS) elicited an automatic unconditioned response (UCR) in the form of salivation.
