“…The possibility of age or sex affecting bisection performance has previously been discussed, respectively, in terms of asymmetric changes or differences across hemispheres (De Agostini et al, 1999;Failla et al, 2003;Fujii et al, 1995;Hausmann et al, 2002Hausmann et al, , 2003Roig & Cicero, 1994). The age-related differences on line bisection found in the current study suggest that cognitive processes in older subjects (>30 years) during a manual (visually mediated) task are qualitatively different to younger subjects.…”

“…Indeed, only a few studies have examined the separate effects of either age or sex. Four studies that examined the effects of age all report variable results (De Agostini et al, 1999;Failla et al, 2003;Fujii et al, 1995;Hausmann et al, 2003). One reason for such discrepancies in reported findings is the distribution of age and sex grouping involved.…”

“…One reason for such discrepancies in reported findings is the distribution of age and sex grouping involved. One study did not distinguish the sex of their subjects (Hausmann et al, 2003), another reported results but only as a function of sex (De Agostini et al, 1999), while another collapsed results across the sexes (Fujii et al, 1995). All four compared uneven age-cohorts and failed to test subjects across different age groups.…”

Line bisection is an established clinical task used to diagnose visuospatial neglect. To date, few studies have considered the extent to which age and sex as background variables contribute to bisection performance. Both variables affect the neural substrates underlying cognitive processes and hence the behavioural performance of bisection. The purpose of this study was to examine the effects of age and sex on normal bisection performance, using three different line lengths to elucidate the influence of these potential contributing factors. Seventy men and 70 women, divided equally into seven age-cohorts between 14 and 80 years, bisected lines. Results indicated clear age- and sex-related differences both in the magnitude and direction of bisection deviations across the three line lengths. Differences are discussed in terms of neural changes across the adult lifespan including hemispheric differences and hormonally mediated changes.

“…Participants had a restricted age range (17-42 years) and a higher level of education that may not be representative of many patients evaluated for neurological functioning. Studies have shown that overall between-hand performances change with age (Bryden et al, 1996;DeAgostini et al, 1999;Fennell, 1986). Some researchers claim that age affects RCFT copy accuracy (Mitrushina et al, 1999), and others say that only minor decrements happen with age (Chervinsky et al, 1992).…”

“…We expected performance differences between preferred and nonpreferred hand, particularly for speed (Provins, 1997;Roy, 1996;Triggs, Calvanio, Levine, Heaton, & Heilman, 2000) and accuracy (Carson, Elliot, Goodman, & Dickinson, 1990;DeAgostini, Curt, Tzortzis, & Dellatolas, 1999;Salazar & Knapp, 1996;Zacharias & Kirk, 1998); however, we expect the differences to be clinically insignificant. The use of the nondominant hand has been shown to influence drawing performance (Zacharias & Kirk, 1998) but not to clinically interfere with completing other neuropsychological tests such as the Benton Visual Retention Test (BVRT) (Dee & Fontenot, 1969), some Wechsler Adult Intelligent Scale (WAIS) subtests (Briggs, 1960), Trail Making Test (Horowitz & Caplan, 1998), and the Clock Drawing Test (Bush, 2000).…”

Comparison of nondominant- and dominant-hand performances on the Copy portion of the Rey Complex Figure Test (RCFT)

Road accidents and falls often result in injury to the dominant hand; however, few studies have evaluated whether the use of the nondominant hand confounds pen and paper assessments. This study used a counterbalanced within-subjects design to assess the copy accuracy on the Rey Complex Figure Test (RCFT) of 154 undergraduates using both their right and left hands. Handedness was determined using Briggs and Nebes's (1975) revision of Annett's Handedness Questionnaire. Two independent scorers used objective scoring criteria (Meyers& Meyers, 1995) with high interscorer reliability. Performance differences were statistically but not clinically significant. Nondominant- and dominant-hand performances did not differ from normative data: A total of 78.9% scored above the impairment cutoff score using the nondominant hand compared to 83.7% using their dominant hand. In the event an individual's dominant hand is compromised, performance using the nondominant hand on the RCFT could produce scores within the normative range and would not falsely suggest neuropsychological impairment.

Spatial asymmetries (“pseudoneglect”) in free visual exploration—modulation of age and relationship to line bisection

et al. 2021

When humans visually explore an image, they typically tend to start exploring its left side. This phenomenon, so-called pseudoneglect, is well known, but its time-course has only sparsely been studied. Furthermore, it is unclear whether age influences pseudoneglect, and the relationship between visuo-spatial attentional asymmetries in a free visual exploration task and a classical line bisection task has not been established. To address these questions, 60 healthy participants, aged between 22 and 86, were assessed by means of a free visual exploration task with a series of naturalistic, colour photographs of everyday scenes, while their gaze was recorded by means of a contact-free eye-tracking system. Furthermore, a classical line bisection task was administered, and information concerning handedness and subjective alertness during the experiment was obtained. The results revealed a time-sensitive window during visual exploration, between 260 and 960 ms, in which age was a significant predictor of the leftward bias in gaze position, i.e., of pseudoneglect. Moreover, pseudoneglect as assessed by the line bisection task correlated with the average gaze position throughout a time-window of 300–1490 ms during the visual exploration task. These results suggest that age influences visual exploration and pseudoneglect in a time-sensitive fashion, and that the degree of pseudoneglect in the line bisection task correlates with the average gaze position during visual exploration in a time-sensitive manner.
