Data were sampled from the VIVE tracker at 50 Hz and collected using a customized Unity (Unity Technologies, San Francisco, CA) program. Mean joint angles in the presentation and replication phases were calculated by averaging 100 data points (2 seconds) prior to each ‘relax’ cue. The relax cue occurred after the three second hold time both in the presentation and replication phases of the trials (Fig. 3). [Figure 3 near here.]Mean presentation and replication angles were used to calculate variable (VE) and constant (CE). Variable error, a measure of consistency, was calculated as (1)where x is the replicated angle, P the presented angle, M the mean replication difference, and n the number of trials. Constant error (CE), a measure of accuracy which takes direction into account, was calculated as (2)where x is the replicated angle, P the presented angle, and <i>n</i> the number of trials.<b></b>
