This article reports the preliminary findings of a research project involving the analysis of a large number of academic articles. It is proposed here that genres (such as explaining and reporting) can be related to particular types and interactions of cognitive process. They typically exhibit patterns of relationship that can be associated with these cognitive processes. Thus a primary difference between the explanation genre and the argument genre appears to relate to the preponderance of grounds-conclusion relationships in the latter. It is also proposed here that text-types (such as academic articles) can be related to particular types of macropattern. A primary difference between academic articles which report on information and emphasise explanation and academic articles which report on information and emphasise problem resolution is that the former tend to have an overall structure of General-Particular (Topic-Restriction-Illustration), whereas the latter tend to have an overall Problem-Solution structure.
