In Chapter 2, I argued that a disciplined distinction between tasks is required because without such a distinction it is not possible to know what one is talking about, and theorising ends up in a mess. For such a distinction, a theory of internal task performance is required – a theory that provides the theoretical means and concepts for expressing similarities and differences between tasks. Because in Chapter 2 neither an appropriate characterisation of the mind nor a decent unit of analysis was available, I had to rely on what authorities said about differences in tasks. With the help of Bridgeman, Gibson, and Neumann, I arrived at a preliminary classification of laboratory tasks in ‘report’ tasks and ‘act’ tasks, with within the ‘report’ tasks a further distinction between ‘name’ tasks and ‘read’ tasks.
