8. high arousal levels in the brain: E-mail from Jerome Kagan to the author, June 23, 2010.
9. many different kinds of arousal: E-mail from Carl Schwartz to the author, August 16, 2010. Also note that introverts seem not to be in a baseline state of high arousal so much as susceptible to tipping over into that state.
10. excited fans at a soccer game: E-mail from Jerome Kagan to the author, June 23, 2010.
11. a host of evidence that introverts are more sensitive: This has been written about in many places. See, for example, Robert Stelmack, “On Personality and Arousal: A Historical Perspective on Eysenck and Zuckerman,” in On the Psychobiology of Personality: Essays in Honor of Marvin Zuckerman , edited by Marvin Zuckerman and Robert Stelmack (Pergamon, 2005), 17–28.

Saklofske and Moshe Zeidner (New York: Plenum Press, 1995): 367–96. Or, as the psychologist Brian Little puts it, “extraverts often find that they are able to handle cramming for speeches or briefings in a way that would be disastrous for introverts.”

7. When she was a girl … She decided to find out: The biographical information about Aron comes from (1) interview with the author, August 21, 2008; (2) Elaine N. Aron, The Highly Sensitive Person: How to Thrive When the World Overwhelms You (New York: Broadway Books, 1996); (3) Elaine N. Aron, The Highly Sensitive Person in Love: Understanding and Managing Relationships When the World Overwhelms You (New York: Broadway Books, 2000).
8. First Aron interviewed thirty-nine people … lightbulb burning a touch too brightly: Aron and Aron, “Sensory-Processing Sensitivity.” See also E. N. Aron, “Revisiting Jung’s Concept of Innate Sensitiveness,” Journal of Analytical Psychology 49 (2004): 337–67. See also Aron, The Highly Sensitive Person .
9. They feel exceptionally strong emotions: In laboratory studies, looking at pictures designed to create strong positive or negative emotions, they reported feeling more emotionally aroused than nonsensitive people. See B. Acevedo, A. Aron, and E. Aron, “Sensory Processing Sensitivity and Neural Responses to Strangers’ Emotional States,” in A. Aron (Chair), High Sensitivity, a Personality/Temperament Trait: Lifting the Shadow of Psychopathology , symposium presented at the Annual Meeting of the American Psychological Association, San Diego, California, 2010.

13. highly empathic: Aron and Aron, “Sensory-Processing Sensitivity.” See also Aron, “Revisiting Jung’s Concept of Innate Sensitiveness.” See also Aron, The Highly Sensitive Person . And see the following fMRI studies: Acevedo, “Sensory Processing Sensitivity and Neural Responses to Strangers’ Emotional States.” And see Jadzia Jagiellowicz, “Faster and More Intense: Emotion Processing and Attentional Mechanisms in Individuals with Sensory Processing Sensitivity.” Note that many personality psychologists who subscribe to the “Big 5” theory of personality associate empathy not with sensitivity (a construct that is gaining attention, but is relatively less well known than the Big 5), but with a trait known as “Agreeableness” and even extroversion. Aron’s work does not challenge these associations, but expands them. One of the most valuable aspects of Aron’s work is how radically, and fruitfully, she reinterprets personality psychology.
