  James’ specious present and Stern’s ‘presence-time’ obviously have much in common – both are intended to designate the brief temporal window through which we are directly aware of change and persistence – but in one respect they are very different. Stern construed this window in an Extensionalist way, as extending over a brief interval of ordinary time. James, by contrast, followed Ward and Hodgson and subscribed to a Retentional interpretation. Or at least he did so in the Principles, in other writings a different story is told; see Section 3 of the supplementary document  The Specious Present: Further Issues  for more on the interpretation of James.
