Psychological behaviorism is a research program within psychology. It purports to explain human and animal behavior in terms of external physical stimuli, responses, learning histories, and (for certain types of behavior) reinforcements.his non-behavioral something is environmental stimuli and an organism's interactions with, and reinforcement from, the environment. So, the third reason for behaviorism's appeal is that it tries to avoid circular, regressive explanations of behavior.
The AAPD's official position is that because of a lack of research, whitening strips aren't safe for kids and teens under the age of 15. But that doesn't mean your child has to live with dull-colored teeth. Instead, good hygiene and the right products can help polish those teeth until they gleam â no bleach necessary.
Fillings, crowns, bridges and bondings, etc. are not affected. Tooth whitening is long lasting but not permanent. A touch-up maybe needed every few years or more often if you smoke, drink coffee, tea, or wine. Reasons for Teeth Whitening: Normal wear and yellowing of outer tooth layer as you age. Stained teeth due to prolonged exposure to certain foods, food colorings, drinks such as coffee, wine, tea. Yellow, brown stained teeth from tobacco use.
