Narrative:

I; a private pilot; was getting dual instruction in the practice area west of EMI. We had just finished slow flight including turns of 90 degrees; albeit with a nose-high attitude. I was recovering the plane to straight and level flight in a cruise configuration for the next maneuver. When I looked left to begin a clearing turn; I saw that we were overtaking what appeared to be a C172 at our 10 o' clock and about 500 ft above us. It was close enough to surprise me; but not close enough to see the n-number. Within seconds; we established radio contact on the CTAF for dmw as is customary for flights in the practice area. We deconflicted our intentions and continued flying.I believe we got into this situation because I fixated on the manifold pressure and RPM gauges. My outside scan was just a quick glance at the horizon; and did not include time for a traffic scan. I had portable ads-B receiver operating; but was paying attention to the display.also; segmenting the flying into individual maneuvers that each started with clearing turns took away focus on looking for traffic at other times in the flight.
