In experiments in the information processing approach, subjects always receive an instruction and generally perform according to that instruction. For theory, this raises the problem of the implementation, structure, and causal powers of the internal representation of the instruction, i.e., of what I called the instruction-induced action plan. As argued in Section 2.4, this problem is the problem of the implementation, structure, and causal powers of the act component of intentionality, of James’s (1890/1950) ‘mind knowing’, and of what I prefer to call the Intending Mind. So, what I have now to look for is an adequate characterisation of ‘mind knowing’. What I want to ﬁnd is a decent ‘unit of analysis’ for the Intending Mind.
