Plainly, though, if the removal of a physical defect is followed by improvement in the school progress, it may be argued that the presence of the defect was a causal factor in the previous retardation.
Wallin, in his book, "Mental Health of the School Child," discusses several other investigations of the relation of intelligence to physical defect.
In the first (that of a physical defect) it is hardly probable that an organic defect would manifest itself in the form of stuttering or stammering, but rather in some other form of defective utterance.
There may be two exceptions to this, however, one being the case of a child with a physical defect in the organs of speech and the other that of a child who has inherited from the parents a predisposition to stammer or stutter.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "physical defect" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
