If the child constructs his identity out of the bits of discourse about him that he picks up in the Wincottian environment, the adolescent attains a sexually-differentiated identity through a process we propose to call “ coat of arms ” : fragments of the body, eroticized by the play of partial drives would through this process be seen to be assembled into a whole constituting sexually-differentiated identity. The case of Akira, who captures bits of her friend’s body with her cell phone camera, enables us to investigate this coat-of-arms aspect of the construction of the sexually-differentiated identity of the subject, and even of the object, in adolescence.
