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
a. performance decreased when landmarks were removed that had been viewed longer.
b. participants did not notice that the landmarks were missing and their performance was uneffected.
c. participants had been relying on all landmarks to navigate.
d. performance increased when non-informative landmarks were removed.

The correct answer is option a. "performance decreased when landmarks were removed that had been viewed longer".

Explanation:

Hamid and collaborators while recording eye movement in a group of participants that were trying to figure out how to navigate a maze. Part of the study was to put landmarks that would not aid maze navigation and then remove them. Even tough the landmarks would not aid maze navigation they helped the participants in other means, probably the ones located at corners were most helpful and the ones that were there since the study started. This is explained by the fact that performance decreased when landmarks were removed that had been viewed longer.
