I believe the answer is:
noting
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">perceiving</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for noting that I've seen before include "Recording in writing" , "Observing or taking down" , "Observing and jotting down" , "Paying close attention to something" , "Seeing" .)
