Values represent mean (SD). The range is also included. σSVV and σ represent trial-to-trial variability in the no-frame and oriented-frame conditions, respectively. CFT represents the average of time of rod alignment for Frame−18° and Frame+18° presentations. Log time: log-transformed mean alignment time with base “e.” All parameters in Nyborg’s analyses are in degrees. Young adult: n = 33; older adult: n = 27. Significant difference at .
