A. Bisection (mean with standard error) of 3-, 5-, 7- and 9-unit number intervals belonging to the first three decades in patients with (N+) and without (N−) left spatial neglect in the bisection of horizontal visual lines and in a sample of age-matched healthy controls (C). Positive values on the abscissa indicate bisection errors (in units) toward numbers that are higher than the true interval midpoint, negative values indicate errors toward numbers lower than the interval midpoint. Error rates of N+, N− and C are reported in tables inserted inside the panel of each decade. Error rates the bisection of 9-unit and 7-unit intervals were comparable among decades for both interval lengths (Group × Decade ANOVA: all F < 1.6 and all p > .19). With 9-unit intervals N+ and N− made more errors than C [Group: F (2,100) = 7, p = .001; planned comparisons: p < .02] and with 7-unit intervals N− made more errors than C [Group: F (2,99) = 4.4, p = .01; planned comparison: p < .01]. A significant Group × Decade interaction was found for 7-unit intervals [F (4,198) = 3.8, p = .01]: planned comparisons showed that within the second and third decade N− made more errors than C (p < .01). B. Bisection (mean with SE) of 7-, 5- and 3-unit number intervals belonging to the first decade. Bisection errors are reported (Y-axis) as a function of interval position within the decade (X-axis).
