Examples of retardation in a Sentence

  1. U. S. Government Study On The Labeling Of Children:

    The term "learning disability" has appeal because it implies a specific neurological condition for which no one can be held particularly responsible, and yet it escapes the stigma of mental retardation. There is no implication of neglect, emotional disturbance, or improper training or education, nor does it imply a lack of motivation on the part of the child. For these cosmetic reasons, it is a rather nice term to have around.

  2. Lindsey Graham:

    The statement of [Sen. Rand] Paul would create anxiety because he's a doctor, he's a respected senator and there is no evidence that I'm aware of that a vaccine causes mental retardation, if he has that evidence he should come forward and let the scientific community do something about it. You cannot scare people by anecdote.

  3. Denis Viljoen:
