Social inequalities are associated with different levels of access to reading and writing due to the educational background needed to develop such skills (RIBEIRO, 2003). Writing is a cognitive task in which several demands (ideational, textual, linguistic, procedural, etc.) compete for attention. In this sense, we conducted a literature review that covers the last 10 years with the purpose of investigating how studies in the field of psycholinguistics of bilingualism have contributed to the teaching and learning of writing in order to assist in decision making during writing. From the perspective of psycholinguistics, the definition of skilled writing involves the need to develop linguistic and textual genre knowledge in the target language (MANCHÓN, 2013). For the investigation of such skilled writing, methodological advances (RODRIGUES, 2019) have made it possible to monitor the writing process synchronously and non-invasively with the use of screen recording, recording of keys pressed on the computer (keyloggers), and eye tracking in order to subsidize school practices (BREUER, 2019; TIRYAKIOGLU, PETERS, VERSCHAFFEL, 2019). The reviewed literature broadly encompasses the subdivision of the writing process into planning, formulation/ translation, and revision/ editing according to models by Flower & Hayes (1980, 1981); Hayes (1996); Kellogg (1996). These sub processes interact with each other cyclically, i.e., they are not implemented linearly, but recursively throughout the writing process. At last, we compiled sample psycholinguistics investigations that were incorporated to teaching and learning practices regarding bilinguals writing through these languages: Brazilian Portuguese, English, and German.
