The Role of Internal Information in the Spatial Learning Task through Path Integration

Two experiments were conducted to investigate the role of internal information. The path completion task revealed that internal (vestibular and kinesthetic) information facilitates the accuracy of the homing direction, especially when the number of turns increases. The spatial learning task revealed that the information enhances learning relative locations of points in the path when tracing back on the path is needed to estimate directions. It was concluded that internal information would contribute to forming survey knowledge by providing the homing directions through path integration.
