sentences:  The number of adolescents who experience an imaginary audience effect cannot be described with any sort of statistics because an imaginary audience is experienced in all adolescents.According to Jean Piaget, a Swiss developmental psychologist known for his epistemological studies with children, every child experiences imaginary audience during the preoperational stage of development.He also stated that children will outgrow this stage by age 7 but as we know now this stage lasts much longer than that.
