kaheart [24]

Matthew is being taught to use the potty through the process of <u>"shaping."</u>


Shaping is the way toward reinforcing progressively ever nearer approximations to a coveted terminal conduct. The shaping of conduct begins at an early age. For instance, a youngster figures out how to pull itself up, to remain, to walk and to at last move about through fortification of somewhat extraordinary cases of practices.

Besides, people use them as an incorrect way to deal with problems, so this is something that happens every day.

As the consumption of pills is normal and shows how sick that society owing to the permanent control and surveillance that is damaging people because it doesn't give then freedom or the ability to think. The men take it as something that happens every day, but they do not seem phased by it because they don't have the tools to realize what is happening.
