Stylistic in speech .. The repetition of certain words does not appear intended to clear

It is a repetition of certain words whose intent does not appear clear. We see a sick person repeating the words "red or green" ... the signal is either red or green ...

The patient may answer all questions with the same answer. If asked what is your name? He said: "Praise be to Allaah." Then he asked: Where are you? He said: Praise be to Allaah. Then he was asked: "In which days are we?" Praise be to God, and so on. This phenomenon may indicate stagnation, refusal to communicate with others, insularity or obstinacy.
