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.

What is like to live without touch or movement/position sense? The only way to understand the importance of these senses, so familiar we cannot imagine their absence, is to ask someone in that position. Ian Waterman lost them below the neck over forty years ago, though pain and temperature perception and his peripheral movement nerves were unaffected. Without proprioceptive feedback and touch the movement brain was disabled. Completely unable to move, he felt disembodied and frightened. Then, slowly, he taught himself (...) to dress, eat and walk by thinking about each movement and with visual supervision. In Losing Touch, the narrative moves between biography and scientific research, theatre, documentary and zero gravity. The book is the result of nearly 30 years close collaboration between author and subject. (shrink)
