It's called "The Echo Effect" and also has some scientific backing to it [0] > we introduce the echo effect, a less researched phenomenon of verbal mimicry, in a real-world setting. Study participants, 330 currency exchange office customers, were assigned into one of three experimental and two control conditions. Careful attention to research design produced results that address issues raised in the mimicry literature and more clearly define the boundaries of verbal mimicry. The results demonstrate that while repetition of words is important in increasing an individual’s tendency to perform prosocial behaviors, the order in which they are repeated back is not; verbal mimicry is more powerful mechanism than dialogue; and, for nonmimicry control conditions, no response produces the same result as a brief response.
