Outline of Final Research Achievements

Infant picking-up from the floor was longitudinally observed at 1.5, 3, 5, and 7 months of infants' age. Mother's holding patterns changed after the infant's head held up steadily, and the speed of picking-up significantly increased at 3 months. Analysis by a motion-capture system also indicated an increase of speed in maternal manual approach with the infants' age.The mothers' sense of difficulty in their own holding was correlated with the paucity of the infants' active participation in the holding at 3 months, whereas it was correlated with the mothers' negative feeling in holding at 5 months.
