The world of communication: non-verbal communication (NVC), neuro-linguistic programming (NLP) and persuasion strategies

What are the forms, methods and characteristics of communication? Communication, understood as the exchange of information from an issuer to a recipient, comes into contact with all the social and cultural spheres belonging to it and is focused here to show the main markers that characterize it. The work is based on an analysis of all those aspects that can influence the communication exchange or even distort the meaning of the message sent. The research questions were also addressed to the fascinating field of non-verbal communication and the characteristics of body gestures, understood as distinctive signals with a strong social impact, also and above all in police interviews and interrogations. Particular reserve was addressed to the many years of experience of Michael Napier, special agent of the prestigious Quantico FBI Behavioral Sciences Unit, for his meticulous work on the aspects necessary in the proper execution of an investigative investigation. The work ends with a current reflection and deepening on the techniques of persuasion and manipulation of communication, which can become a real weapon to strike, on the one hand positively convincing and working on self-esteem and to help individuals achieve their own objectives, on the other hand by manipulating and misinforming a large slice of the population with psychological, political and digital tools.
