SUMMARY:Workload Carryover Effects due to Varying Rotations in a Laparosco
 pic Training Environment
DESCRIPTION:Mesoma Iloanusi (Texas Tech University)\n\nLaparoscopic surger
 y requires adaptation to altered visuospatial mappings caused by indirect 
 camera views. Previous research has shown that exposure to one camera rota
 tion can influence subsequent performance under a different rotation; howe
 ver, the effects on mental workload remain unclear. The present study inve
 stigated workload carryover effects during a laparoscopic pointing task in
 volving varying camera rotations. 104 undergraduate participants completed
  movements across familiarization, initial rotation, and subsequent rotati
 on phases in a low-fidelity laparoscopic simulator. Participants were assi
 gned to six rotational groups, and mental workload was assessed using the 
 NASA Task Load Index (NASA-TLX). We hypothesized that workload would decre
 ase at subsequent rotations when the same adaptation mechanism was engaged
  across exposures. Results showed a general tendency toward reduced worklo
 ad following prior exposure, with a significant reduction observed at the 
 90° rotation following exposure to 45° rotation, consistent with predictio
 ns. Marginally significant reductions were also observed at 120° and 135°.
  Findings suggest that prior exposure to certain camera rotations may faci
 litate mental workload adaptation in laparoscopic environments, though eff
 ects were not consistent across all conditions. Future research should exa
 mine whether these findings generalize to expert surgeons.\n\n
