“…In addition, a series of recent studies reported abnormal sensitivity to point-light biological motion, a stimulus containing form information [11], in preterm participants with periventricular brain injury (PVL), but not in agematched low-risk preterms [5][6][7]. Consistent with our results, significant disorders of form recognition have been reported in preterm children with PVL [12][13][14][15], but not in those without brain damage [16].…”

We tested 26 school-aged children born preterm at a gestational age below 34 weeks, 13 with and 13 without periventricular brain damage, with four different visual stimuli assessing perception of pure global motion (optic flow), with some form information (segregated translational motion) and form-defined static stimuli. Results were compared with a group of age-matched healthy term-born controls. Preterm children with brain damage showed significantly lower sensitivities relative to full-term controls in all four tests, whereas those without brain damage were significantly worse than controls only for the pure motion stimuli. Furthermore, when form information was embedded in the stimulus, preterm children with brain lesions scored significantly worse than those without lesions. These results suggest that in preterm children dorsal stream-related functions are impaired irrespective of the presence of brain damage, whereas deficits of the ventral stream are more related to the presence of periventricular brain damage.

“…Yet, the author also specified that the performances on some subtests (e.g., recognition of incomplete figures) still improved after the age of 11 years. Our results are in accordance with several studies reporting the early 1095 development of late perceptual processing in relation to view-independent object representation (Bezrukikh & Terebova, 2009;Bova et al, 2007;Stiers et al, 2001).…”

“…It was inspired by the block matching task of the L94 battery (Stiers et al, 2001). This subtest 630 was divided into two distinct tasks: one had a grid within the frame and the other only a frame; both tasks included one, two, or three red squares.…”

“…Pisella et al (2013) reported a significant improvement in performances for length and surface judgment tasks until 8 years, but until adulthood for the orientation judgment task. In contrast to this long-term development of a single basic perceptual 1070 characteristic (e.g., length, surface, orientation), the literature reported that the discrimination of simple shapes or drawings (processing at least two basic perceptual characteristics at the same time) was already mature by the age of 6 years (Bova et al, 2007;Stiers 1075Stiers et al, 2001.…”

“…An association between PVL and impairment of object recognition has also been reported (van den Hout et al, 2004;Stiers et al, 2001;Stiers, De Cock, & Vandenbussche, 1998, which is significantly correlated to specific anatomical features, such as decreased volume of the peritrigonal white matter and thinning of the parieto-occipital white matter (Ito et al, 1996;Goto, Ota, Iai, Sugita, & Tanabe, 1994;Koeda & Takeshita, 1992). Recently, we have shown that the perception of flow motion in diplegic children with cystic PVL is impaired, both for translational and rotational flow motion (Guzzetta et al, submitted).…”

Abstract& We report here two cases of two young diplegic patients with cystic periventricular leukomalacia who systematically, and with high sensitivity, perceive translational motion of a random-dot display in the opposite direction. The apparent inversion was specific for translation motion: Rotation and expansion motion were perceived correctly, with normal sensitivity. It was also specific for random-dot patterns, not occurring with gratings. For the one patient that we were able to test extensively, contrast sensitivity for static stimuli was normal, but was very low for direction discrimination at high spatial frequencies and all temporal frequencies. His optokinetic nystagmus movements were normal but he was unable to track a single translating target, indicating a perceptual origin of the tracking deficit. The severe deficit for motion perception was also evident in the seminatural situation of a driving simulation video game. The perceptual deficit for translational motion was reinforced by functional magnetic resonance imaging studies. Translational motion elicited no response in the MT complex, although it did produce a strong response in many visual areas when contrasted with blank stimuli. However, radial and rotational motion produced a normal pattern of activation in a subregion of the MT complex. These data reinforce the existent evidence for independent cortical processing for translational, and circular or radial flow motion, and further suggest that the two systems have different vulnerability and plasticity to prenatal damage. They also highlight the complexity of visual motion perception, and how the delicate balance of neural activity can lead to paradoxical effects such as consistent misperception of the direction of motion. We advance a possible explanation of a reduced spatial sampling of the motion stimuli and report a simple model that simulates well the experimental results. &
