👉 Psychological engineering is an interdisciplinary field that applies principles from psychology, human factors, and behavioral science to design systems, products, and environments that optimize human performance, well-being, and satisfaction. It involves understanding how people think, feel, and behave to create solutions that align with human capabilities and limitations. By integrating insights from cognitive psychology, organizational behavior, and ergonomics, psychological engineering aims to enhance user experience, reduce errors, increase efficiency, and foster positive interactions between humans and technology. This approach is crucial in fields like user interface design, workplace safety, and healthcare, where the goal is to create systems that are intuitive, accessible, and supportive of human needs and behaviors.
