Document Summary
Grading data for 2nd reflection data: kelsey"s grades, range 70-95, average 81, daniel"s grades, range 70-95, average 78% Final paper deadline: extended to sunday april 5th at midnight. Ted talk: sarah jayne blakemore: 50 years ago, it was widely assumed that the majority of brain development took place in the first few years of life. The regulation of the prefrontal cortex in moderating responses is not as strong in children as it is in adults. What is the evidence for this developmental mismatch: structural evidence, study: mills, goddings, clasen, giedd, blakemore (2013) They chose to look at the amygdala, nucleus accumbens, and. There was an increase in regional brain matter in the amygdala, a decrease in the nucleus accumbens, and a steep decrease in grey matter in the prefrontal cortex. The limbic system regions don"t look like they are undergoing much developmental change (consistent with the idea that these brain regions mature earlier than the prefrontal cortex)
