PSYB32H3 Lecture Notes - Lecture 4: Motor Skill, William Harris Ashmead, Perspective Control
Document Summary
Motor development: age norms for important motor milestones. Iii. the development of locomotion: perceptual information in locomotion, perceiving the properties of surfaces, control of balance, visually-guided locomotion, a systems approach to development of walking, component skills, relation between skills. Achievement of motor development is not related to subsequent growth in intellectual or emotional development. The ability to reach for and graphs objects in our visual field = visually guided reaching. Figure-ground separation - depth relationships: motor skills. Fine-motor coordination and control: visual-motor integration and coordination. Visual guidance of the hand in proper direction. Perspective control when reaching for objects that are moving, need to predict where it"s going to be and then grasp. 1 2 months: glance at objects when present, begin to fixate objects for 5-10 sec, grasping reflex but again isolated from vision. Show hand movement but arms not organized with vision. 3 4 months: mutual grasping, 1 or 2 hands.
