2. Theories Where did it all come from?

3. Theories Evolutionary Basis Foundation for communication and language?

7. The Brain and Chemicals The Limbic System Localized? Distributed?

8. The Brain and Chemicals Amygdala Fast track vs. slow track

9. The Brain and Chemicals Testosterone—male aggressiveness, decrease emotional face recognition Cortisol—inhibits aggression (counters testosterone) Serotonin—increased impulsive and aggressive behavior due to low levels Due to inadequate turnover (i.e., how serotonin is release, absorbed, metabolized, replaced)

10. Stress and Health Too much, too long!

11. Stress and Health Yerkes-Dodson Law

12. Stress and Health Stress General Adaptation Syndrome Alarm—sympathetic nervous system arousal Resistance—adrenal release of cortisol for prolonged arousal Exhaustion—loss of energy and increase in risk and vulnerability

13. Stress and Health Stress HPA Axis

14. Stress and Health Immune System

15. Stress and Health Prolonged Stress Psychosomatic Illness Good ways to regulate? Identify emotions and urge actions Recognize experiences as local, not global Identify and implement strategies (e.g., mindfulness) Seek support network
