Document Summary
Neurons: nerve cells, basic units of nervous system. Cell body, axon (sending info, white matter b/c myelinated - insulated in fat means faster), dendrites (receiving info) Puning: those that aren"t used are replaced/disappears while those that are used becomes stronger. Corpus callosum: large collection of axons that connects l/r hemisphere. Prefrontal cortex: high level cognitive functioning; reasoning, decision, self control. Matures before prefrontal cortex can"t control these emotions yet. Dopamine increases reward seeking & risk taking impulse control still developing. Not sure if brain changes causes maturity or maturity causes brain change. Higher likelihood of successful recovery at adol. Adol actively constructs their world (not passively learning) Equilibration: cognitive conflict/disequilibrium causes shift in understanding world. Understand world by coordinating sensory experiences with motor activity. Operation: mental action actions (of previously physical ones) Intuitive where reasoning can be applied to concrete examples. Conservation of length, width, number, mass, area, volume, etc. Hypothetical deductive reasoning: develop hypotheses, pick best path.
