A note from Dr. Roelofs: The experiment was run using an eyetracker and the NESU software developed at the Max Planck Institute in Nijmegen. The MPI-made NESU sofware presented pictures and words in .pla format, which is no longer supported. I have attached the original pictures and words in .pla format, but could not convert these files in more modern formats, like .gif or .bmp For all pictures but one (i.e., zwemvlies [flipper]), however, I could find the bmp version in my MPI picture data base. I have attached these pictures in bmp. According to my memory, the picture of flippers was a very standard one, so it should not be too difficult to find a good alternative by googling. The Dutch word 'zwemvlies' refers to one member of a pair of flippers, so it must have been a picture of one "flipper" (not the fish, but "swimming shoe").
