Cyberpsychology can be defined as the study of mental phenomena related to cyber-systems and their context. The term "cyberpsychology" is a neologism which refers to two 1 interwoven concepts: "psychology", the study of behavior and thought, and "cybernetics", the science of the laws of control and communication for mechanisms and machines operations. While it is common to speak of the confrontation between AI and natural intelligence (NI), or of transcending NI with an AI that can be misunderstood as something frightening, which might cause disturbances or even threaten our individual and collective liberties, many scientists have been developing a reflection under the term "cyberpsychology". The advent of intelligent machines is for some a solution to cope with human problems; for others, it stands as a threat to the future of humanity. Undoubtedly, the cybernetic world keeps transforming humans and it will probably transform them even more in the future. Intelligent robots are used in factories, hospitals, railway stations or airports. They will soon appear on battlefields. Cyber collaborators invade our homes, offices and living spaces. This is not without consequences on society, on social groups, but also on individuals, as they transform their body and their mind. How do humans adapt to this global change, and how does the cybernetic world adapt to humans who change? These questions lead scientists to take an interest in these joint evolutions, in their mutual effects on thought, intelligence, emotions, personalities, and on the modes of machines design, their use and their transformation. Thus, it is necessary to investigate the relation between humans and cybernetic systems, artificial intelligence, robots. The evolution of AI involves new words, new concepts, but also new theories that encompass a study of the natural functioning of humans and of the machines they have built and which, today, are fully integrated in their natural environment (anthropotechnical). Tomorrow's human beings will have to invent a psychology of their relation to machines, but the challenge is to develop also a psychology of machines, artificiel intelligent software or hybrid robots. In this context, cyberpsychology is at the crossroads of two main fields: psychology and cybernetics. It is understood as the science of the mechanisms of behavior and thought in humans, and of the psychological laws that apply to the cybernetic space and to cybernetic systems. As an autonomous discipline correlated to its mother disciplines, it has been developing since the end of the 20th century, and it shares their characteristics, their limits !-Cyberpsychology and Cyber-Psychology are synonyms.
