There are occasionally agenda building studies that track specific presidential quotes in a fashion that an echoing study might (e.g., Horvit, Schiffer, & Wright, ), or indexing studies that work at the level of the “theme” (e.g., Althaus, ) or “label” (e.g., Bennett et al, ) and are thus somewhat similar to echoing studies. And, because “echoing” is a common term, there are occasionally studies that use the word casually to describe the circulation of frames in relation to indexing or cascading activation (e.g., Rowling et al, ).…”
