Working through

Does "working through" in the following three paragraphs from the same book mean the same meaning of something like "coping with"?

1. Klein interprets Kjar’s paintings, one of a wrinkled old woman, the other a portrait of her mother as a young, strong, beautiful woman, in terms of reparation, as follows: the portrait of the wrinkled woman represents the damage done to the mother’s body, with the portrait of the mother in her youth exemplifying reparation and the working through of sadistic phantasy. As Briony Fer says, for art historians such as Adrian Stokes ‘[t]he greatest power art has is the achievement of a state of unity which ultimately overcomes the trauma of loss and its sadistic repercussions’.

2. British art critics such as Adrian Stokes in the 1940s and 1950s and Peter Fuller in the 1980s emphasised the biological elements in Freud and KIein to discuss artworks as being a working through of relations with the mother and as having an explicit psycho-sexual dynamic that revolves around fixed notions of male and female.

3. For Freud, the social address of art means that it is on the side of the pleasure principle, as even when it presents painful experiences there is a yield of pleasure in their working through.
