I watched “Arrested Development: Adolescent Development & Juvenile Justice” by Elizabeth Cauffman. Elizabeth points out that since children in adolescence, their prefrontal cortex is not fully developed, so they may experience mood swings and they're tend to react based on emotions, instead of controlling behavior and emotions through the rational prefrontal cortex. As a result, adolescent are more likely to engage in risk-taking behaviors and make bad decision without considering the serious consequences. In this case, parents play an important role in adolescence of children. They should get to know adolescent children from another angle and communicate with them in different ways. Moreover, parents should pay attention to children's emotional changes, be patient to listen and show interest in what they are involved in. Every moves of parents will have a profound and lasting impact on children.

I chose to watch “Want Smarter, Healthier Kids? Try Physical Education!” By Paul Zientarski. Zientarski has created a highly successful program called the Learning Readiness Physical Education (LRPE) program. This program has made great improvement in test scores, behavior and childhood obesity. Zientarski emphasizes using Physical Education in learning is important, because exercise will builds brain cells and helps improve academic performance. There are many studies has point out exercise has a positive effect on memory, concentration, and indoor class performance. I think, for children who have negative personality whose need special plan to improve behaviors, doing exercise is a good way to allow them vent their feelings, and the brain secretes dopamine, so that making children generate a positive emotions. Exercise is not only promoting physically health, but also promoting mentally healthy.

I chose to watch Stereotype Threat. According to Dr. Steele, stereotype threat is usually used to describe people who worry about others will judge themselves based on their negative stereotypes. Stereotype threat can increase psychological burden and affect personal performance. In the experiment, Dr. Steele gave some students very difficult math tests. These students had the same mathematical background. When they were told that there was no gender differences in this test and that they would not evaluate any stereotyped images of groups, women got the same grades as men. Once they were told that there was a gender difference, women were frustrated and feel worried, which affected their grades. It can be seen that stereotype threat can makes huge influence on personal performance. I think negative stereotypes are harmful to racial and gender differences, because it gives people unfair treatment whether in educational, employment, housing or other opportunities.
