Schematic diagram of the testing apparatus for unconstrained cognitive flexibility viewed from above (a) and from the side (b). Dimensions of the apparatus was 50 cm × 10 cm × 25 cm (l × w × h). A removable plexiglas wall separated one-third of the apparatus to make a start box. When the wall was removed, the test area was exposed, consisting of a ramp leading to the reward pot at the end of the apparatus. A panel was placed in the middle of the ramp making 4 cm of open space at the bottom of the ramp. For the digging task on test day, the ramp was covered by sawdust to a height of 6 cm from the bottom to restrict access to the reward pot
