Consistent with this, no significant differences in jumps and holds/acrobatic non-flight were found between the original and helmet conditions. In summary, elements without longitudinal axis rotations are well-suited for HMD execution, and results can be improved with better hardware and longer familiarization.

Peak velocity was impacted by focus with an EP leading to higher values than IO and IP. For average velocity EP had higher values than IO, and approached higher values than IP.

Around 60 % of self-talk interventions support these differential effects predictions (Hardy et al., 2018). Attentional focus research may strengthen the matching hypothesis, where an external focus has been shown to improve performance and facilitate learning for a variety of motor tasks (Chua et al., 2021). It has been postulated that instructional self-talk impacts performance though attentional mechanisms (Galanis & Hatzigeorgiadis, 2020). Infusing internal and external attentional focus into instructional self-talk may allow more consistent performance differences to emerge between instructional and motivational self-talk.

Thirteen healthy young adults walked along a virtually projected walkway with precision footholds oriented in either a straight line or with a single 60°, 90°, or 120° step or spin turn to the right.

Hierarchical bootstrapping analyses revealed stereotyped alternate foot placement strategies across turn angles that differed between step turns and spin turns. Specifically, alternate foot placement for step turns aligned with the person's approach trajectory when they identified a new obstacle, regardless of turn angle; whereas alternate foot placement for disrupted spin turns aligned with the person's future turn trajectory.

The Tor-CoP group also exhibited lower repeatability values in the CoP-controlled game compared to the CoP-Tor group. Our results suggested a directional transfer of motor learning from the Tor-controlled game to the CoP-controlled game, because performance improved in the CoP-controlled game when it was played after a Tor-controlled game.
