“…Teddy bears cancellation test (Laurent-Vannier et al, 2006): the child aged more than 3 years is asked to cross out or to point to all the teddy bears (n = 15) distributed on the page (21 cm × 29.7 cm, landscape orientation) among 60 distractors (simple drawings such as a shoe). The number of correctly cancelled targets constitutes the score.…”

“…Cancellation tests are widely used to measure visuospatial neglect following brain injury (Ferber & Karnath, 2001;Laurent-Vannier et al, 2006;Linden et al, 2005). The test typically presents a minimally arranged array of targets and distractors on a conventionally sized sheet of paper.…”

Cancellation tests have traditionally been used to measure visuospatial neglect. Recently, such tests have also been viewed as potential measures of executive function. Mark and colleagues (2004; Disorganized search on cancellation is not a consequence of neglect. Neurology, 63, 78-84) developed three objective measures of organization based on reconstructing target-marking pathways from one form of a cancellation test: mean inter-target distance, path intersection rate, and a quantification of overall path uniformity (i.e., predominantly radial versus horizontal cancellation progress) that they termed "best r". However, the validity of these measures with respect to a subjective judgment of organization was not assessed. In the present study, 50 observers rated the overall organization of 50 reconstructed pathways from stroke patients and non-brain-injured adults to allow evaluating the convergent validity of the three proposed executive organization measures. Inter-target distance (r = .86), intersection rate (r = .87), and best r (r = -.69) were all found to be highly correlated with observer ratings. These results indicate good convergent validity for all three executive organization measures on a form of the cancellation test.

The aim of this study was to explore the visuo-attentional skills of children with an ophthalmic disorder. Twenty-four patients and 60 healthy controls between the ages 4 and 7 years, all right-handed with normal or corrected-to-normal close visual acuity, were divided into four age groups. Patients' diagnoses included refractive disorders (e.g., myopia, hypermetropia), strabismus, amblyopia, cataract, and nystagmus. All participants performed nine paper-and-pencil visuospatial tasks aiming to assess selective attention (cancellation tasks), spatial working memory (symbol orientation task), fine visual analysis (embedded figures test), and simple perceptual analysis (shape-matching task). In healthy children, the results showed that performance on all visuo-attentional tasks improved with age. While perception, orientation of attention, and visual working memory develop by the time children begin school (age 5), more sophisticated abilities such as attention disengagement and motor control continue to develop during late childhood. Moreover, a spatial bias in attention orienting appeared with reading acquisition (6-7 years). In ophthalmic children, at 4 years of age defects were observed in all assessed functions, but at 7 years an attentional deficit was virtually the only one remaining. Overall, the results demonstrate that children with an ophthalmologic disorder may experience difficulties with visuospatial tasks despite corrected-to-normal visual acuity.
