Concept Mapping #2 Development from Infancy to Adolesence Development in infancy Development in early childhood Motor Physical By four months, babies grow about 3 inches and gain an avergae of 4.5lbs from their birth weight/height. Growth will slow down around six months and then become gradual. Teething will occur by 4-18months Development in middle childhood Motor and brain Physical Brain Babies begin developing motor skills from the center of their bodies to the tail of their spinal cords, iand from the center of their bodies outward. The part of the brain responsible for basic life functions develop first, followed by the higher areas (thinking/planning). Most brain functions will occur prenatally and or quickly after birth. Around the age 2.5, body proportions have changed greatly. They begin losing their baby rolls due to new bone tissue being formed through a process called ossification. By age 2 children can run, kick a ball, and climb a ladder for the slide. By 3, they are as far as riding a tricycle. The skill to throw a ball over their head doesn't develope Brain until the age of 4. At the age of 5 they have achieved a great amount of control over their bodies and to the point of being able to dress themsleves. Brain development during early chldhood is typically slower than that of infants. This is when myelination of the prefrontal cortex occurs, as well as synaptic pruning. Additionally, neurons that connect different areas in the brain grow in length and branching. Development in Puberty Physical Increased muscle mass and strenght and an increase in fat tissues which changes the appearance of the body; Depends on interaction with environment and genetics Motor Brain Stronger, more agile, and balance improves. They run faster and throw further and more accuratley. Aquire lots of physical skills during this period Emergence of executive functio;Increased speed and capacity of working memory; Autonomous morality Physical Growth spurt, Gender Brain differences:body strength and shape Sexual Primary and secondary sex characteristics. Individual variations of puberty timing. Significant changes to cortex and limbic system. Dopamine and Hormones
