ABSTRACT
We test the effect of a landmark’s visual and structural salience on memory retrieval of turning directions at intersections in a virtual environment. Across three studies, we find an increased decision correctness when the location of the visually salient landmark converges with the turning direction. This pattern is robust across various perspectives, including the return path. We find no performance differences between route repetition and return path. We find some evidence to turn toward a visually salient landmark even if this is not correct. Taken together, a visually salient landmark helps if located in the turning direction, but might be detrimental to a navigator’s ability to recall the correct direction if located on the opposite side.

Notes
1 We did not consider semantic (or cognitive) salience in our research, because we found no satisfying solution to operationalize this aspect to be equally salient and consistent across all participants, as well as showing no cross-interferences with the other two salience dimensions.
2 Please note that also provides information for Study 2 and Study 3 to allow an easier comparison across the studies.
3 A technical problem with the software code resulted in the first ten participants performing 31 rather 32 blocks. Furthermore, participants received wrong feedback about the correctness of their response in about 7% of trials.
4 Individual differences were not the primary focus of our research question. A preliminary inspection of these measures revealed no major relation with the overall correctness in the main experiment. We thus decided to refrain from further analysis of these data. We accounted for individual differences by including the participant id as a random intercept..
