| Abstract: | Simple geometric forms and spatial position markers were tachistoscopically presented to Ss from four age groups (ranging from five years to adult) who responded by recreating the visual array with magnetic tokens.The basic findings were: (a) Ss remembered item positions better than identities; (b) no asymptote of position recall was reached by any age group when up to five position markers were presented; (c) when required to process identity information, position memory suffered, younger Ss showing the greatest decrement; (d) with unlimited viewing time, the pattern of results relating identity and spatial recall was not altered; (e) recall was better for the locations of position markers than for locations of geometric items.The results supported an hypothesis of separate processing mechanisms for spatial location and identity information. Improvement with age seems to result from an increasing ability to integrate the functioning of these separate mechanisms. |
