First, our objective was to assemble chapters authored by recognized experts in sport psychology and performance management. We also wanted chapters to reflect the most contemporary clinical and experimental findings. Most important, the chapters contain many recommendations for improving behavioral sport psychology applications, advancing research, and refining the performance of youth, amateur, and elite athletes. A book of this type cannot cover every relevant topic, but hopefully, we have addressed many of the dominant areas that make up the sport psychology landscape.We are, first and foremost, clinical psychologists, but also avid sport enthusiasts. Dr. Luiselli acknowledges the many coaches who shaped his athletic pursuits in middle school, high school, and college: James C. Murphy, Michael Donato, Richard Sterndale, Jerry Splaine, Louis Gnerre, Rocky Carzo, and Herb Erikson. My father, the late James "Jack the Barber" Luiselli, was my finest coach, always there in the stands, consistently positive, and helping me in ways he probably never realized -I am forever indebted to him. I thank my wife, Dr. Tracy Evans Luiselli, for enduring my tales of athletic conquests long gone and commiserating with me during Patriots, Celtics, Bruins, and Red Sox games. Our daughter, Gabrielle Luiselli, has given us so much pleasure watching her perform on the ice and landing those combination jumps. And to our son, Thomas Luiselli, your exploits on the hockey rink and the lacrosse field fill us with pride -you and your sister are true champions! Dr. Reed acknowledges his father, David Reed, for being a patient trainer, an understanding coach, and most importantly, an unconditional fan and supporter. I thank my mentors, Dr. Thomas Critchfield, Dr. Brian Martens, and my co-editor, Dr. James Luiselli, for supporting my efforts to study the behavioral processes underlying athletic performance. Finally, I thank my wife, Dr. Florence DiGennaro Reed, for humoring me when I claim that my playing of football video games is for the sake of science.
