Children's sensitivity to traffic hazard in peripheral vision
Authors:Siriol S. J. David  Hugh C. Foot  Antony J. Chapman
Abstract:Although children and adults have poorer peripheral vision than foveal vision there is contradictory evidence about the developmental changes that occur in peripheral sensitivity. Previous research on detections of traffic hazard has not, however, provided any evidence that peripheral vision is implicated in the particualr vulnerability of children to pedestrain accidents. In the absence of differences in peripheral detections it was hypothesized that children may nevertheless be less efficient than adults in utilizing information presented in the periphery. Road traffic scenes depicting vehicles in potentially hazardous and non-hazardous positions for road crossings were presented to adults and to childre, aged 7, 9, and 11. Results confirmed that children were relatively no poorer than adults at hazard detection in peripheral vision than in foveal vision, but indicated that they were marginally poorer at utilizing information presented in the periphery, as measured by a vehicle recognition test. Against expectd developmental trends 9-year-olds were as fast as adults at hazard detection, but no different from the other groups of children in recognition performance. Evidence that information detected and assimilated in peripheral vision does not contribute to the high pedestrian accident rates of children comes from the absence of any sex differences favouring girls. Since girls have considerably lower accident rates than boys, it would have been expected that both their detection and recognition performance would have been higher.
