This study examines the working memory systems involved in human wayfinding. In the learning phase, 24 participants learned two routes in a novel photorealistic virtual environment displayed on a 220° screen while they were disrupted by a visual, a spatial, a verbal, or—in a control group—no secondary task. In the following wayfinding phase, the participants had to find and to “virtually walk” the two routes again. During this wayfinding phase, a number of dependent measures were recorded. This research shows that (...) encoding wayfinding knowledge interfered with the verbal and with the spatial secondary task. These interferences were even stronger than the interference of wayfinding knowledge with the visual secondary task. These findings are consistent with a dual‐coding approach of wayfinding knowledge.

Using the Remember/Know procedure, we compared the impact of a reflective repetition by refreshing and a perceptual repetition on subjective experience during recognition memory. Participants read aloud words as they appeared on a screen. Critical words were presented once , immediately repeated , or followed by a dot signalling the participants to think of and say the just-previous word . In Experiments 1 and 2, Remember responses benefited from refreshing a word . In Experiment 2, this benefit disappeared when participants (...) had to refresh one of three active items. Perceptual repetition increased Remember responses in Experiment 1, but not in Experiment 2 regardless of whether participants had just previously seen 1- or 3-items. These findings indicate that under some circumstances, reflective and perceptual repetition may have different consequences for later subjective experience during remembering, suggesting differences in their underlying functional mechanisms.
