Document Summary
Chapter 5: the child"s growth brain, body, motor skills and sexual maturation (part 2/3) The brains plasticity: experience and brain development envir plays a role in brain development plasticity: the capacity of the brain, particularly in its developmental stages, to respond and adapt to input from the external envir. Responsiveness of its neural structures and functions to input from envir. 2 types of experience influence brain development: experiences like touch, patterned visual input, sounds of lang, affectionate expressions from caregivers and nutrition. Trigger synaptic development and pruning and critical for normal brain development. Interference with this normal stimulation = abilities are impaired. Brains respond to diff envir by developing synaptic connections that encode specific and unique experiences. Ex children in mozambique develop aspects of motor cortex that correspond to skills associated with hunting nd fishing vs. Enriched rats had bigger brains bc of enriched envir (this increased the complexity of neurons measured by the number of dendrites they develop)
