Abstract: Memory for the final position of a target is usually displaced in the direction of target motion. This displacement has been suggested to reflect the implied momentum of the target and has been referred to as representational momentum. Similarly, displacement reflects a wide range of influences and information based on physical gravity, friction, and centripetal force. A wide range of theories and models have been proposed to account for representational momentum, involving internalization theory, naïve impetus theory, anticipatory consciousness, network model, eye movement theory, the two-process theory and computational theory. Several considerations for future development were described including addressing a more unified theory of representational momentum, a more specific theory of representational momentum and the processing mechanism of representational momentum.
