“…For the symmetric objects the main effect of priming condition was significant (F(2,108)=2.54, p<0.05) whereas the interaction of priming condition and age was not (F(6,108)=1.62, p=0.14). Figure 2A suggests that, consistent with previous results [20], haptic priming facilitates learning of older children but not that of children in the youngest age group. An additional a posteriori contrast analysis showed a significant (p<0.05) advantage of haptic priming relative to the control condition in age groups 9-10 (non-symmetric and symmetric objects) and 15-16 (non-symmetric objects only), which turned into a significant disadvantage for children aged 8-9 (non-symmetric and symmetric objects).…”

“…The supervised-learning procedure was partitioned into learning units (see [20] for details), each consisting of a learning phase and a test phase. During the learning phase each of the 22 views of the learning set was presented once for 250ms and in random order, followed by the corresponding object label ("1", "2" or "3") displayed for 1 s. During the test phase, each learning view was presented once and assigned to one of the three objects by the observer.…”

“…For example, a recent functional brain imaging study showed that full development of coherent motion in hMT+ is not reached until adolescence (Bucher et al, 2006). Tasks inducing dynamic visual adaptation (Schrauf et al, 1999), configural object recognition (Rentschler et al, 2004) and haptic priming upon configural visual stimuli (Jüttner et al, 2006) require even stronger visual processing demands and possibly the involvement of dorsal stream processing in object recognition. It has been shown that these functions do not mature until adolescence.…”

“…Others, however, suggested that a third area, probably in the posterior, superior parietal cortex, needs to be activated that binds both motion and shape processing areas (Zeki, 2001). This (temporary) binding between shape and motion may be related to attention or spatial processing, and which may have a different developmental time course (Oakes et al, 2006;Rentschler et al, 2004;Ross-Sheehy et al, 2003). Thus, it remains unknown to what extend neural development of SFM processing depends on both the development of motion processing related areas and areas that are not directly related to shape or motion processing.…”

(2008). Dorsal stream development in motion and structure-from-motion perception. NeuroImage, 39(4): [1815][1816][1817][1818][1819][1820][1821][1822][1823] Little is known about the neural development underlying high order visual perception. For example, in detection of structures by coherently moving dots, motion information must interact with shape-based information to enable object recognition. Tasks involving these different motion-based discriminations are known to activate distinct specialized brain areas in adults. Here, we investigate neural development of normally developing children using functional magnetic resonance imaging (fMRI) during perception of randomly moving point-light dots (RM), coherently moving dots that formed a 3D rotating object (SFM) and static dots. Perception of RM enhanced neural activity as compared with static dots in motion processing-related visual areas, including visual area 3a (V3a), and middle temporal area (hMT+) in 10 adults (age 20-30 years). Children (age 5-6 years) showed less pronounced activity in area V3a than adults. Perception of SFM induced enhanced neural activity as compared to RM in adults in the left parietal shape area (PSA), whereas children increased neural activity within dorsal (V3a) and ventral brain areas (lingual gyrus) of the occipital cortex. These findings provide evidence of neural development within the dorsal pathway. First, maturation was associated with enhanced activity in specialized areas within the dorsal pathway during RM perception (V3a) and SFM perception (PSA). Secondly, high order visual perception-related neural development was associated with a shift in neural activity from low level shape and motion specialized areas in children, including partially immature area V3a, to high order areas in the parietal lobule (PSA) in adults.

Visual perceptual skills are basically mature by the age of 7 years. White matter, however, continues to develop until late adolescence. Here, we examined children (aged 5-7 years) and adults (aged 20-30 years) using diffusion tensor imaging (DTI) fiber tracking to investigate the microstructural maturation of the visual system. We characterized the brain volumes, DTI indices, and architecture of visual fiber tracts passing through white matter structures adjacent to occipital and parietal cortex (dorsal stream), and to occipital and temporal cortex (ventral stream). Dorsal, but not ventral visual stream pathways were found to increase in volume during maturation. DTI indices revealed expected maturational differences, manifested as decreased mean and radial diffusivities and increased fractional anisotropy in both streams. Additionally, fractional anisotropy was increased and radial diffusivity was decreased in the adult dorsal stream, which can be explained by specific dorsal stream myelination or increasing fiber compaction. Adult dorsal stream architecture showed additional intra- and interhemispheric connections: Dorsal fibers penetrated into contralateral hemispheres via commissural structures and projection fibers extended to the superior temporal gyrus and ventral association pathways. Moreover, intra-hemispheric connectivity was particularly strong in adult dorsal stream of the right hemisphere. Ventral stream architecture also differed between adults and children. Adults revealed additional connections to posterior lateral areas (occipital-temporal gyrus), whereas children showed connections to posterior medial areas (posterior parahippocampal and lingual gyrus). Hence, in addition to dorsal stream myelination or fiber compaction, progressing maturation of intra- and interhemispheric connectivity may contribute to the development of the visual system.
