Hamid et al. (2010) had participants navigate a maze while recording their eye movements. The maze contained landmarks on the walls at corners and at other positions that would not aid maze navigation. After participants learned the maze, the researchers removed half of the landmarks. The results of this study revealed that:
Performance decreased when the landmarks that were removed had been the ones viewed longer
Participants did not notice that the landmarks were missing and their performance was unaffected
Participants had been relying on all landmarks to navigate and could not complete the maze
Performance increased when the landmarks that were removed had been the ones viewed longer
