  These labels are not standard – in this field there is little by way of terminological uniformity – but for present purposes they will serve (see Kon and Miller (2015) for a more fine-grained categorization). All three models are depicted in Figure 1 below. In each of the diagrams the horizontal line represents ordinary clock-time. Although the Retentional and Cinematic models both trade in momentary (or very brief) states of consciousness – in the diagrams such states are represented by thin vertical lines – these states are construed very differently. In the Cinematic case the momentary contents seem momentary, and are static (they contain no discernible motion or change); in the Retentional case the contents appear to possess a brief temporal depth, containing as they do experienced change and succession – hence the backward pointing arrows, intended to signify the way in which the recent past is supposedly ‘retained’ in present consciousness.
