  Returning to our main theme – the makeup of individual specious presents – while Figures 5 and 6 capture the core features of the Extensional model, they also have their limitations: the Extensional approach can accommodate different views as to general character and composition of consciousness, and these differences do not register in these diagrams. Some philosophers hold that consciousness has an act-object (or awareness-content) structure, so every experiencing – even the simplest –involves two distinguishable components: an awareness (however construed) on the one hand, and an object or content on the other. Other philosophers reject this two-level picture, and hold that contents do not need to fall under an awareness in order to be conscious. As we shall see in §5.4, the Extensional model is compatible with both these views. Divergent conceptions of the nature of perceptual experience are also very relevant in this context. Is the moving item shown in Figure 6 a phenomenal feature of a conscious state, or is it a physical object in motion through physical space? Those who incline to the direct (or naïve) realist view of perception will favour the latter answer, whereas those who subscribe to the indirect realist (or Lockean-style representational) view of perception will favour the former answer. In slightly more general terms, Extensional theorists who believe that in our ordinary perceptual experience we are presented with purely phenomenal items (sense-data, qualia or similar) will regard the visual and auditory contents of specious presents as themselves being phenomenal in nature. Although most Extensional theorists subscribe to this general view of perception – e.g., Foster, Broad, Dainton, Sprigge – there is no obvious obstacle to combining the Extensional conception of the specious present with a direct realist construal of perception. With this combination of views, a typical specious present will consist of a temporally extended episode of awareness, some of whose contents will be internal or phenomenal (e.g., a conscious thought, a mental image), whereas others will be external (e.g., a bouncing ball, a moving  car).[12]
