Deficits in global motion processing have been reported in groups of children with or at risk of abnormal neurodevelopment which has led to the dorsal stream vulnerability hypothesis. However, it is unclear whether the development of global motion processing is associated with the development of other abilities that may rely on the dorsal stream. The purpose of this study was to assess the relationship between global motion detection, stereopsis and motor development in a group of 2-year old children born at risk of abnormal neurodevelopment. Methods: Children born with risk factors for neonatal hypoglycaemia (n=403) were assessed at 24±1 months corrected age. Global motion coherence thresholds were measured using the method of constant stimuli by presenting random-dot-kinematograms and recording the optokinetic reflex. Stereopsis was measured using LANG I&II and Frisby stereotests. Motor functions were measured using the Bayley Scales of Infant Development III (BSID-III). Data were analysed using Spearman’s Rho and multiple comparisons were accounted for using the Bonferroni correction. Results: Global motion coherence thresholds, successfully measured in 334 children, were significantly correlated with BSID-III composite motor (r=-0.19, p=0.001), fine motor (r=-0.16, p=0.004), and gross motor (r=-0.17, p=0.002) scores, with poorer global motion coherence thresholds associated with poorer motor scores. Stereopsis was successfully measured in 333 children using the LANG I&II stereotest and in 222 children using the Frisby stereotest. Both LANG I&II and Frisby stereopsis results correlated with composite motor (r=-0.17, p=0.002 and r=-0.19, p=0.004) and fine motor (r=-0.22, p less than 0.001 and r=-0.20, p=0.002) scores as well as global motion coherence thresholds (r=0.28, p less than 0.001 and r=0.18, p=0.013). However, stereopsis was not significantly correlated with gross motor scores (r=-0.08, p=0.135 and r=-0.065, p=0.337). Discussion: Global motion detection, stereopsis, and motor function were correlated in 2-year-old children. The results are consistent with the hypothesis that the dorsal processing stream contributes to both visual and motor development.
