Saying “echoic” as a result of seeing the word is NOT echoic; nor is saying it as a result of hearing someone say “imitative.”
Note how the first example is missing the second defining feature of echoic behavior, while the second example is missing the third and fourth defining features of echoic behavior:
A form of verbal behavior with the following features:
The response is vocal
It is controlled by a prior auditory verbal stimulus
There is point-to-point correspondence between the stimulus and the response
There is formal similarity between the prior stimulus and the response-product
Formal and dynamic characteristics of both the stimulus and the response
The “meaning” of either the stimulus or the response
Whether or not the current response is reinforced
