A trial of each experimental condition performed during the experimental phase inside the MR imager is presented. Each of the four conditions, A, Allocentric; EU, Egocentric-updating; ERO, Egocentric with Rotation Only; and C, Control; was divided into an encoding phase and a test phase. In the encoding phase, participants saw a presentation of the environment's layout: (A) from a survey perspective, (EU) from a 1-st person ground level perspective with navigation, (ERO) from a 1-st person ground level perspective with a rotation only (C) with a mix of perspectives. In the test phase, participants had to point in the direction of an object using a joystick: (A) from the location of another object, (EU and ERO) from their body position; in condition C, they pointed straightforward.
