Schematic of the revised CWM with 10 T-shaped cul-de-sacs instead of 9. The revised maze has a new start location (S). The escape platform (goal; G) remains the same. The adjustment to the schematic shown in Fig. 3 where one stem was longer than all the others, once corrected, created space for an additional T where the S was in Fig. 3. The revised maze has two possible start locations, but the start location that we use is as shown.
