This volume demonstrates how readers can become more effective parents, teachers, students, coaches, managers, or work supervisors, while also gaining practical skills to enhance their self-motivation, communication skills, and intervention acumen. The first eight chapters explain evidence-based principles from applied behavioral science (ABS) that can be used to improve the human dynamics of any situation involving behavior. Fundamentals from humanism are integrated strategically to show how an ABS intervention can be more acceptable, influential, and sustainable. The following twelve chapters detail the deployment of ABS interventions to optimize performance in a wide variety of fields, including occupational and transportation safety, quantity and quality of organizational work behavior, healthcare, athletic coaching, parenting, pre-school and college education, environmental sustainability, and the control of obesity and alcohol abuse. Applied Psychology provides a thorough review of the latest research in relation to these domains and explores issues for future investigation.
