Note: Values shown are the mean (M), standard deviation (SD) and 95 % confidence interval (95% CI). Results of pared sample t-test (t) are presented with p values and degrees of freedom. T0 = test. T1 = retest. Mean dif. = mean differences. PR = peripheral reaction. PRL = peripheral reaction left. PRR = peripheral reaction right. FOV = field of vision. VAL = visual angle left. VAR = visual angle right. TD = tracking deviation. NOHL = numbers of hits left. NOHR = numbers of hits right. (sec) = measured in seconds. (n°) = measured in degrees. (pixel) = measured in pixels. (N) = measured in numbers of hits.
