Abstract:Motor sequence learning (MSL) has been a staple in psychological research for as long as it has been discovered. One area that relies heavily on efficiency regarding skills rooted in the theory of MSL are Minimally Invasive Surgeries (MIS). A prominent MIS performed regularly are flexible bronchoscopies. Therefore this thesis focuses on assessing the individual differences and learning potentials in a simulated flexible bronchoscopy setting, based on the theory of learning curves, established by Hearhcote et al. (2000). Ten novices (7 females; M(age) = 20.1; SD(age) = 2.51) in the field of bronchoscopy were recruited through the University of Twente SONA student system to take part in the experiment, requiring them to perform flexible bronchoscopies on the GI-BRONCH Mentor™ while wearing an Xsens MVN Awinda motion capture suit collecting data on their acceleration potential. All of the subjects showed improvement during both of the Tasks assessed in this experiment. Learning curves on the movement time per participant, as well as acceleration potential show ambiguous results. There is also no clear transferability of skills between tasks within the results, as indicated in the learning curve parameters. The measured acceleration potential did not have direct influence on success during this experiment. However, consistency of the measured tasks was found to be a possible factor in the lack of clear results. Small trial size, as well as varying difficulty within Task 1 are both potential influences that would ideally be revised in future research. Conclusively, while the results of this experiment showed improvement within subjects, as well as giving indications on individual differences, no clear statements about learning curve parameter potential can be made.
