Answer: Youssif is <u><em>an object relations </em></u>therapist.
Explanation:
Object relations therapy has its roots in <em>Sigmund Freud's psychoanalytic theory</em>, and people's need to form relationships with other people. <em>Object relations therapist</em> wants to help his patient explore early mental images that influenced present relationships with other people, and thus resolve any problems/difficulties in those relationships. In doing so, the therapist focuses on one particular person that significantly affected his patient's life. Object relations theorists believe that, in early childhood, infants form representations of themselves in relation to others, and that those representations have a large effect on their relationships in adulthood.
Technology has always been closely linked to the ways in which people have lived. Before the development of civilization, humans lived for many millennia with tools and techniques that allowed them to live successfully in a wide variety of environments. From primitive stone implements to fairly sophisticated and specialized tools, prehistoric humans developed technologies that allowed them to increase their control over the natural world. In return, the tools that they used increasingly changed their way of life.
