: - looks good to me (but I didn't see the page beforehand).  
 : - I fixed the account of the Wallas model (and yes, I read the book, so I should know what Wallas said! Wallas followed Poincaré, Helmholtz and a Russian psychologist with a name beginning with 'V' (Vyosetsky?), whose name I dont remember, quite closely, and the Wallas model most definitely consusts of the stages I indicated. 
 : - I also don't recall anything about Wallas linking his model to an evolutionary perspective, and suspect that that is incorrect. It was certainly part of Simonton's agenda, and I suspect that Simpnton simply ascribed that interpretation to Wallas (if Simonton said anything along these lines at all). The major evolutionary contribution to the psychology of creativity came, of course, from Campbell. 
 : - While I'm on the topic, I don't think the Wallas model should really be in the 'definitions' section. I suspect it should be in a 'psychological models of the creative process' or 'models of the creative process' section. 
 : HTH!
