Maturation of performance with space-displaced vision.

This study tests two specific hypotheses of neurogeometric theory: that acritical period in maturation of space-displaced visual feedback in behavioroccurs in childhood, and that a differential organization of inverted, reversed, and inverted-reversed visual feedback in motion will be found at the time when children are first capable of giving compensatory response to the spatial disorientatiop of vision. In keeping with theoretical expectations theresults showed that when the different inverted and reversed feedback conditions could be performed, the response to the inverted feedback condition wasthe poorest, while that to the reversed condition was the most effective.

Angular displacement of the visual feedback of motion.

The hypothesis is that such displacement produces no disturbance of behavior within a limited "normal" range, but that a breakdown angle can be found beyond this range which will produce disturbance in motion in proportion to the magnitude of the feedback displacement. Results with two tasks specifically support the hypothesis that limiting angles of neurogeometric control of motion and variation in performance occur with varying magnitudes of angular displacement of feedback.
