    It is not the case that Retentional models have a distinct advantage over Extensional models in accommodating temporal illusions such as the flash-lag effect and the phi-phenomenon.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Extensional models can incorporate post-dictive revision mechanisms, whereby later neural signals retroactively update the content of earlier perceptual representations without contradiction.
      ?

      Think about whether this reason is strong or weak

    • 2.Psychophysical evidence from Eagleman and Sejnowski (2000) supports post-diction as the actual neural mechanism underlying the flash-lag effect, making extensional post-dictive accounts empirically competitive with retentional ones.
      ?

      Think about whether this reason is strong or weak

    • 3.If the extensional model revises rather than simultaneously holds conflicting contents, P3's claim of forced simultaneous contradiction is false, and the alleged advantage of retentional models dissolves.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.The phi-phenomenon and flash-lag effect can be explained by predictive interpolation operating over discrete extensional snapshots, as argued by Dennett in 'Consciousness Explained' through the Multiple Drafts model.
      ?

      Think about whether this reason is strong or weak

    • 2.Retentional models, by embedding temporal flow within the structure of each conscious moment, generate their own explanatory burden: they must account for why retentional content of a moving stimulus coheres rather than producing smearing or doubling artifacts.
      ?

      Think about whether this reason is strong or weak

    • 3.The purported advantage of retentional models in handling temporal illusions thus trades one explanatory problem for another, undermining the claim of distinct advantage.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Temporal illusions involve cases where a stimulus occurring later than time t affects the character of what is perceived as occurring at t itself.
      ?

      Think about whether this reason is strong or weak

    • 2.Retentional models allow what is perceived as occurring at t to vary across different specious presents, so a spot of light can be perceived as stationary in specious present S1 and as moving in a later specious present S2.
      ?

      Think about whether this reason is strong or weak

    • 3.Extensional models represent each stimulus only once, meaning conflicting perceptual data about the same moment t yields contradictory experiences (the spot being perceived as both stationary and in motion simultaneously).
      ?

      Think about whether this reason is strong or weak
