Infants’ prospective control during object manipulation in an uncertain environment

摘要: This study investigates how infants use visual and sensorimotor information to prospectively control their actions. We gave 14-month-olds two objects of different weight observed high they were lifted, using a Qualisys Motion Capture System. In one condition, the visually distinct (different color condition) in another identical (same condition). Lifting amplitudes first movement unit analyzed order assess prospective control. Results demonstrate that lifted light object higher than heavy object, especially when vision could be used When being confronted with condition), showed lifting pattern what expressed by significant interaction effect between condition on amplitude. These results indicate (a) about can actions (b) are able even without weight. argue infants, absence reliable weight, heighten dependence non-visual (tactile, memory) estimate pre-adjust manner.
