From Enlightenment philosophy to modern neuroscience, multiple
mechanisms have been identified for our intersubjective ability
to feel another's pain. Physiological resonance between individuals
has been demonstrated in heart rate, facial muscle activity, skin
conductance, neural activity and pupil dilation. Yet, despite this
shared reactivity, we often do not help those in need and sometimes
even cause their distress. This divide between feeling and acting
exists not only in our behavior, but also in our neuroscientific
research, which almost completely segregates mechanisms of empathy
and altruism (citing different articles, using different paradigms,
and emphasizing different neural regions). We seek to resolve this
empathy-altruism divide by dissociating the neural mechanisms for
recognizing and resonating with another's state from the neural
mechanisms that motivate us to act. Theory and data predict that
under certain conditions, acute physiological arousal to another's
distress will motivate active helping while stressful physiological
activation (acute or chronic) will inhibit helping due to a state
of self-focus and protection. We will investigate empathy and altruism
under conditions of acute and chronic physiological activation.
Further, we will examine the utility of a stress-reducing intervention
as a means to increase compassion in an applied setting. This work
is theoretically grounded in interdisciplinary models of empathy
and altruism and combines behavioral, autonomic, hormonal, and
neural measures to investigate responses to real targets of need.
In so doing, we can resolve the empathy-altruism divide while testing
a novel theoretical model of altruism and a real-world intervention
for compassion fatigue in a health-care setting.
Biographies
Stephanie D. Preston, Ph.D., has a highly interdisciplinary
background that has included work in multiple species and levels
of analysis, allowing her to employ basic knowledge about the neural
and physiological bases of behavior to understand complex human
behavior in domains such as empathy, altruism, and decision making.
She received her Ph.D. in Behavioral Neuroscience from the University
of California at Berkeley where she studied the effects of stress
on decision making in food-storing animals. This was followed by
a post-doctoral fellowship in the Department of Neurology, at the
University of Iowa, examining the role of emotion in empathy and
decision making. She is currently an Assistant Professor at the
University of Michigan investigating the ways in which emotion
and social behavior affect complex, real-world resource-allocation
decisions regarding material resources and altruistic aid to others.
Tony W. Buchanan, Ph.D., works on the intersection between emotion
and cognition. Dr. Buchanan's work has focused on the role that
emotion plays in the encoding and retrieval of long-term memories.
This work has been conducted both in neurologically healthy individuals
as well as in neurological patients with damage to specific brain
regions. More recent work in Dr. Buchanan's laboratory has focused
on the role of emotional memory in the recurrence of major depressive
disorder and the biological substrates of empathy for others undergoing
stress. Dr. Buchanan's work has been funded by the National Institute
of Mental Health and the National Alliance for Research on Schizophrenia
and Depression. He received his Ph.D. in Biological Psychology
from the University of Oklahoma and went on to a postdoctoral fellowship
in Cognitive Neuroscience at the University of Iowa. He is currently
Assistant Professor of Psychology at Saint Louis University.
