 One important thing to keep in track of with your man's, your tax, your interverbal, your colleagues, your textuals, and writing text behaviors is the term point-to-point correspondence, which is a verbal stimulus that has the beginning and middle and end, and the behavior matches the beginning, middle, and end of that stimulus. A verbal stimulus that the beginning, middle, and end matches the end of the very beginning, middle, and end of the tax-screwed-it-up. But I'd said the term. Oh, well, then that would be an end-verbal and not an echoic. Now it's confusing. Yes, so let's go back and redo that. So, for point-to-point correspondence, the stimuli, the verbal stimulus, if you will, has to have the same beginning, middle, and end for the response, beginning, middle, and end. The verbal stimulus has to have the same beginning, middle, and end as the response is beginning, middle, and end. Ta-da! Ta-da!
