This unique multidisciplinary volume examines the dynamics of behavioral change and its maintenance, from the individual to the wider domains of public policy. Coverage traces how change may be achieved, sustained, or derailed, as well as underlying neurobiological, behavioral, and social processes that fuel unhealthy and risky behaviors. Contributors offer a wide range of prevention and intervention strategies for supporting positive health habits from improved food choices to abstinence to compliance with treatment. These mechanisms are then transferred to the societal level in studies of evolving public perception of salient issues such as climate change, gender disparities, and drug policy. Included among the topics: Motivating change in addiction via modulation of the dark side. Changing drug use and other health-related behavior in vulnerable populations. Change and maintaining change in school cafeterias. Understanding social structural barriers and facilitators to behavioral change. Strategic communication research to illuminate and promote public engagement with climate change. A provocative rendering of motivation in its macro and micro dimensions, Change and Maintaining Change will interest researchers, practitioners, and clinicians interested in diverse areas such as smoking and other addictions, improvement and relapse in therapy, development and treatment of anxiety disorders, and social cognition and decision-making.

The volume editorsfor this 55th volume of the Nebraska Symposiumon Motivation are Rick Bevins and Tony Caggiula. The volume editors coordinated the sym- sium that lead to this volume including selecting and inviting the contributors and coordinating all aspects of editing. My thanks go to the Rick and Tony and to our contributors for excellent presentations and chapters. This Symposium series is supported by funds provided by the Chancellor of the University of Nebraska-Lincoln, Harvey Perlman, and by funds given in memory of Professor Harry K. Wolfe to the University of Nebraska Foundation by the late ProfessorCoraL.Friedline.We areextremelygratefulfortheChancellor'sgenerous support to the Symposium series and for the University of Nebraska Foundation's support via the Friedline bequest. This symposium volume, like those in the recent past, is dedicated to the memoryof Professor Wolfe, who broughtpsychologyto the University of Nebraska. After studying with Professor Wilhelm Wundt, Professor Wolfe returned to his native state, to establish the ?rst undergraduate laboratory in psychology in the nation. As a student at Nebraska, Professor Friedline studied psychology under Professor Wolfe.

This volume marks the fiftieth anniversary of the Nebraska Symposium on Motivation, the longest continuously running symposium in the field of psychology.
The motivational processes involved in drug abuse, the largest health problem in the United States, are the subject of eight thought-provoking essays that probe behavioral, cognitive, evolutionary, and physiological perspectives. George F. Koob discusses the implications of an allostatic view of motivation in psychopathology. Harriet de Witt considers the dual determinants of drug use in humans, reward and impulsivity, while R. D. Spealman and his research team assess the triggers of relapse in nonhuman primates. Jaak Panksepp and associates elucidate the role of emotional systems in addiction via a neuroethological perspective, while Michael T. Bardo and Linda Dwoskin describe the biological connection between novelty and drug-seeking motivational systems. Drive, incentive, and reinforcement, along with factors controlling the reinitiation of drug seeking and the environmental sources of motivation round out the remaining discussions by Roy A. Wise, Jane Stewart, and M. Vogel-Sprott.
