  As we saw in §2.5, in characterizing his presence-time, Stern held that experiences unfolding over an interval of time can “form a unified and complex act of consciousness regardless of the non-simultaneity of individual parts.” Since the successive phases of the specious present depicted in Figure 5 do form a unified ensemble, they clearly conform to Stern’s conception of a presence-time. James sometimes referred to the specious present a duration-block, which he characterized thus: ‘We do not first feel one end and then feel the other after it, and from the perception of the succession infer an interval of time between, but we seem to feel the interval of time as a whole, with its two ends embedded in it.’ (1890: 610) The specious present of the Extensional model conforms to this characterization. Since the successive constituents which compose a duration-block are live experiences, the Extensional specious present also conforms fully to the Immediacy Thesis (see §3): change can be experienced with the same force, vivacity (or immediacy) as colour, sound or any other phenomenal feature.
