Lee, Assistant Professor of Psychology Xavier E. Cagigas, Assistant Clinical Professor, UCLA Semel Institute for Neuroscience Paul E. Haerich, Professor of Psychology Holly E. R. Morrell, Associate Professor of Psychology iii ACKNOWLEDGEMENTS I am grateful for my dissertation chair, Dr. Grace Lee, who helped me get through, and complete this project. Without her diligence, direction, and encouragement this would not have been possible. I am thankful for all the guidance and support I received from each of my committee members. In particular, I would like to express my deepest gratitude to Dr. Paul Haerich, who believed in me from the beginning of my journey and allowed me to join his Psychophysiology of Emotion and Human NeuroCognition Lab. Participating in his lab work, as well as his seminars and lab meetings were key in helping me formulate my ideas and to ultimately design my project. Thanks to Dr. Holly Morrell for her input and kind support. Finally, I am grateful for having had the honor to have Dr. Xavier Cagigas be part of this experience. His advice and guidance have been crucial in my development as a scientist and practitioner. Most importantly, I would like to thank my husband, Martin Corona for waiting these long years with patience and for his love and support. I am also grateful for my beautiful daughter, Mikaella, who has inspired me to continue pursuing my professional and personal goals and ultimately become a better person. Lastly, I would like to thank God for his undeniable presence and unconditional love throughout this journey. iv CONTENT Approval Page .................................................................................................................... iii Acknowledgements ............................................................................................................ iv List of Figures ................................................................................................................... vii List of Tables ..................................................................................................................... ix List of Abbreviations ...........................................................................................................x Abstract .............................................................................................................................. xi Chapter 1.
