Attentional Focus Instructions and Conscious Movement Processing in Older Adults

"All participants will complete a series of walking trials. They will first be requested to perform three practice walks followed by three walking trials on a 7.4m straight level-ground firm walkway (GW) and the other three walking trials on a 7.4m straight foam walkway (FW) in a randomised order. The dimension of the foam walkway in the FW will be 8m (length), 0.8m (width), and 0.3m (height). The starting and finishing lines of the FW will be positioned at 0.3m from each side of the FW's edges. Thus, the lengths of the FW and the GW will be identical (i.e., 7.4m). Participants will be asked to walk 7.4m and stop for each walking trial.~After a 10-minute rest break, participants will perform nine walking trials on the GW and the other nine walking trials on the FW, including three repetitions of three different attentional focus instructions (external focus \[EF\], internal focus \[IF\], and no specific focus \[NF\]) in the GW and FW in a randomised order."
