Virtual layouts and target distribution in task.

The basic task was to remember where a virtual cartoon animal (duck or penguin) was hiding, watch it disappear, get ‘teleported’ to a new viewpoint, and then point with the ‘magic wand’ to its hiding place. Panels A and B are screenshots of the environments. Panels C and D are overhead layout diagrams of the landmarks and targets. The trials that use the ‘near’ targets are the only ones considered here (in blue) since the ‘far’ trials (in green) were extremely noisy for the youngest age group. We will refer to these as the ‘Jetty’ (panel A and C) and ‘Arctic’ (panel B and D) datasets.
