Transitional disks are protoplanetary disks around T Tauri stars, with inner holes or gaps which are surrounded by optically thick outer, and often inner, disks. The origin of the gaps and holes in transitional disks has been much debated: photoevaporation, dust settling and coagulation, inside-out evacuation by magnetorotational instabilities, and dynamical effects of companions, notably giant planets, have all been suggested. A key test of these mechanisms is the mass accretion rate of the host star. Those mechanisms which depend upon far- or extreme-UV radiation from the star would lead to several observable trends between accretion rate and disk or gap properties. In this talk, we present some 50 transitional disks we identified with the Spitzer Space Telescope's Infrared Spectrograph, and their stars' mass accretion rates estimated from our observations with the Infrared Telescope Facility's SpeX instrument. We analyze thereby the observable trend involving mass accretion rate with the location and size of the gaps, and compare with trends involving other properties of star and disk.
