Performance Carry-Over Effects Caused by Exposure to Multiple Visuo-Spatial Distortions in a Laparoscopic Training Environment
SessionPoster Session 1
DescriptionLaparoscopic surgeries entail a camera being inserted into the body that projects the surgical field onto a monitor. This process introduces visual-motor distortions, as surgeons need to view the tissue from the camera’s perspective. These distortions get worse when the camera does not provide a front view. Prior research suggested two adaptation mechanisms under such rotations. A gradual adaptation mechanism accounts for performance to increasingly deteriorate until a threshold is reached (threshold at 90˚). The relatively superior performance at 180˚ has been attributed to an axis inversion mechanism. An axis inversion and a gradual backward rotation has been hypothesized when rotations fall between 90˚ and 180˚. When surgeons must use a second camera perspective, exposure to the prior rotation might impact motor performance at the subsequent camera perspective. We hypothesized beneficial performance carry-over effects when rotations are both above or below the threshold as both rely on the same adaptation mechanisms. Consistent with our hypotheses, we observed tendencies for improved performance for successive rotations below the threshold. However, the performance carry-over effects for rotations separated by the threshold were mixed. For successive rotations above the threshold, no beneficial carry-over effects were observed, which might be due to a floor effect.
