Citing another author’s summary of other works in a journal article I want to use the information from this block of text talking about psychoanalysis:


  Some authors (e.g. Allison et al., 2006 and Turkle, 1995) compare the player and avatar's relationship to a transmission field, as roughly defined by psychoanalysis: the avatar is not in exclusive competence of the player, while not being completely separated from them. It lies somewhere near the boarder of external and internal (psychological) reality.


I am unsure how to put it in my paper. Do I still say that the information is from the article I'm reading it from, or would I mention the authors of that information? Something like:


  Lukas Blinka in his article entitled "The relationship of players to their avatars in MMORPGs" compares the relation of a player to their avatar to that of a transmission field...


The relevant style guide is MLA.
What you need to do is write it so that the author of article is clearly identified as the compiler, rather than the originator, of the idea. For example:


  Lukas Blinka notes that some critics have “compared the player and avatar’s relationship to a transmission field” (##).


You would only include Blinka's article in your bibliography. If I cared to know who those critics were, I'd go to his article to find them.
