Fig. 12From: Getting nowhere fast: trade-off between speed and precision in training to execute image-guided hand-tool movementsA closed loop model for adaptive skill assessment as shown here needs to be considered to ensure that evaluation of desired behaviours is appropriate and not subject to the development of a single observer bias over time. Adjustment of learning criteria and test design (step 3 of the loop) may be necessary in the light of data relative to temporal and spatial aspects of tested performance (step 2 of the loop)Back to article page
