Studies using primates suggest that alcohol promotes aggression but only in dominant male monkeys during the mating season when testosterone levels are high. 2. An example of an environmental effect on testosterone secretion would be when losing a tennis match results in lowered blood levels of testosterone. 3. The proposition that facial expressions of emotion are innate is supported by the observation that the same facial expression for an emotion is observed in all cultures. 4. Darwin argued that the expression of emotion in humans evolved from similar expressions in other animals. 5. Damage to the amygdala can impair recognition of ________ but not ________. facial emotion expression; recognition of emotion using tone of voice 6. The emotion of disgust involves activation of neurons within the insular cortex 7. People with volitional facial paresis are unable to voluntarily move the facial muscles. 8. Which disorder would greatly impair the capacity of a person to succeed in acting? volitional facial paresis 9. What is true of the role of the amygdala for the recognition of emotion? Amygdala damage impairs the ability to use facial expressions for emotion recognition. 10. According to the James-­‐Lange theory, feelings of emotions are produced by feedback from the behaviors and physiological responses caused by emotion-­‐producing situations. 11. Studies by Ekman and colleagues suggest that simulated facial emotional expression changes sympathetic activity. 12. With regard to facial emotional expression, negative emotional expressions are more intensely expressed on the left side of the face. 13. The unique aspect of Patient S.P. is that after removal of her right amygdala, she was unable to recognize her own facial emotional expressions. 14. At what time are female rhesus monkeys more likely to fight with male rhesus monkeys? near the time of ovulation. 15. What hormones, when introduced daily to a female mouse, will NOT make the treated female more likely to fight with a strange female mouse than placebo? estradiol 16. Intermale aggression is reduced in mice whose vomeronasal nerves have been surgically damaged. 17. What type of hormone effect is exemplified by the ability of early testosterone exposure to sensitize brain circuits implicated in aggression? organizational 18. What is an example of a personal moral dilemma? throwing another person onto a grenade in order to save a larger group 19. Recent research suggests that emotions may play the most important role in the formation of Moral Judgments 20. What cortical region plays a role in analyzing social situations? ventromedial prefrontal 21. Inadequate activation of the _________ and enhanced activation of the _________ together may result in excessive anger, even leading to harm to others. prefrontal cortex; amygdala 22. A formal definition of aggressive behaviors includes those behaviors involved in predation. 23. On what does serotonin seem to exert a controlling effect? risky behaviors. 24. What behaviors can be elicited by electrical stimulation of the dorsal periaqueductal gray matter in the cat? defensive rage behavior. 25. What neurotransmitters, when elevated, inhibit aggressive behaviors? serotonin 26. What are some of the major components of an emotional response? behavior, autonomic activity, and hormonal secretions. 27. Neurons within the amygdala are activated by ________ stimuli tend to activate neurons in the amygdala Emotionally relevant 28. What is a function of the autonomic component of an emotional response? Mobilizing energy for vigorous movement 29. Emotion research has been mainly focused on anger and fear 30. Prenatal exposure to androgens increases aggressive behavior in all studied species. 31. The amygdala is involved in the recognition of ________communicated via ________. fear; facial expression 32. Which statement best illustrates the James-­‐Lange theory of emotion? Laugh and you will be happy. 33. The amygdala is involved in ________, but not in ________. recognition of facial expression; emotional expression 34. What hormones, when introduced daily to a female mouse, will make the treated female more likely to fight with a strange female mouse than placebo? testosterone 35. Female rhesus monkeys are more likely to engage in fights with other females just prior to menstruation 36. ___________ may be the cause of impulsive aggression, which can be treated with _________. impaired serotonin prefrontal activity; fluoxetine 37. Imagine that you are testing the levels of various chemicals in the cerebrospinal fluid of a human male with a lengthy violent criminal history, including carjacking, assault and murder. You would expect to find _______ levels of ________ in their CSF. reduced; 5-­‐HIAA 38. Inactivation of the central amygdaloid nucleus results in reduced blood levels of stress hormones. 39. What is a function of hormonal secretions that come about with an emotion? Forming glucose within muscle 40. Inputs originating from what structures inhibit emotional responses? ventromedial prefrontal cortex 41.
