Recent research highlights the role of sensory landmarks in human wayfinding. Given the predominant focus on the visual system in previous studies, we investigated the possibility of auditory landmarks in form of physical as well as mentally imagined auditory landmarks. In an online experiment, 121 participants (82 female, 38 male; mean age: 31.33 years, SD = 14.61 years) were guided through a 15-intersection maze, where they were presented with landmarks accompanied by directional indicators (e.g., arrow pointing left). In the condition with physically presented auditory landmarks, animal sounds were presented as stimuli (e.g., barking dog), while participants in the mentally imagined auditory landmark condition received written instructions to imagine the specific animal sounds. After this learning phase, participants’ task in the wayfinding phase was to accurately recall the route with the previously learned associations between landmarks and directional indicators given at each intersection. In a subsequent recognition phase, participants were presented with either 30 auditory cues or the instruction for mental imagination (15 landmarks from the learning phase and 15 distractors). They were then asked to indicate whether each cue had been presented before. Results demonstrate that it is possible to navigate using physical and mentally imagined auditory landmarks. Participants even achieved a higher orientation performance when auditory landmarks had to be imagined compared to physically presented auditory landmarks. This suggests that the use of mentally imagined auditory landmarks can be an effective method for orientation and may even be more efficient than relying on physically presented auditory landmarks.
