To this end, four studies will be conducted. In study 1 (data collection complete; manuscript in preparation), it was investigated (i) if and how CG can be experimentally induced after offering virtual slips, (ii) how CG after repeated slipping differs qualitatively from the CG that is displayed after participants are merely warned, and (iii) how long it takes for CG to extinguish after slips are no longer presented. In study 2, it will be determined (i) whether and how age affects experimentally induced CG, (ii) how CG strategies are related to clinical measures of walking ability and fear of falling, and (iii) how the extinction rate of experimentally induced CG is related to age, walking ability and fear of falling. In study 3, we will determine to what extent experimentally induced CG affects reactions to unexpected, aberrant perturbation stimuli, and how this differs between young and old participants. Finally, in study 4, we will examine whether CG can be shaped through a single training session based on self-induced treadmill slips. Collectively, these studies will provide insight into how CG develops, how it relates to age, walking ability, and fear of falling, and how it can be shaped through training. This knowledge can serve as a starting point for the development of targeted interventions to promote the adequate use of CG strategies by older adults.
