Objective: The American Psychological Association (APA) celebrated its 125th anniversary in 2017. As part of this celebration, the APA journal Neuropsychology has published in its November 2017 issue 11 papers describing some of the advances in the field of neuropsychology over the past 25 years. Method: The papers address three broad topics: assessment and intervention, brain imaging, and theory and methods. Results: The papers describe the rise of new assessment and intervention technologies, the impact of evidence for neuroplasticity on neurorehabilitation. Examples of the use of mathematical models of cognition to investigate latent neurobehavioral processes, the development of the field of neuropsychology in select international countries, the increasing sophistication of brain imaging methods, the recent evidence for localizationist and connectionist accounts of neurobehavioral functioning, the advances in neurobehavioral genomics, and descriptions of newly developed statistical models of longitudinal change. Conclusion: Together the papers convey evidence of the vibrant growth in the field of neuropsychology over the quarter century since APA's 100th anniversary in 1992. General Scientific Summary Over the quarter century between 1992 and 2017, the field of neuropsychology has rapidly grown in its theoretical sophistication and in its methods to study brain structure and function. This special issue of the journal Neuropsychology reviews the field's advances in assessment and treatment, brain imaging, and theory and methods.
