Document Summary
Dynamic systems view: proposed by esther thelen, motor skills assembled for perceiving and acting, motor skills represent solutions to the infant"s goals, new motor behavior influenced by multiple factors. Involve large-muscle activities: development of posture, dynamic process linked with sensory information. Involve finely-tuned movements: children lack fine motor skills at birth. Infancy: perceptual-motor coupling necessary for grasping, palmer grasp, pincer grasp, supports shifts from touch to vision. Childhood: refinement of grasping (pincer at 3 years, use of tools (crayon at 5 years vs. pencil at 7 years) What are sensation and perception: sensation, occurs when information is transmitted through sensory receptors (eyes, ears, tongue, nostrils, skin, perception, the interpretation of what is sensed. Visual perception: visual acuity, an object 20 feet away from a newborn is only as clear as it would be if it were. 240 feet away from an adult with normal vision: face perception. Infants show an interest in human faces soon after birth: color vision.
