    HistoryEditSee Inverse

    At least some problems with the early/late debate stem from an assumption about the linearity of the processes that support personal-level thinking, not from an assumption about linearity of neural processing per se.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.The communications-engineer perspective treats as wasteful the idea that physical properties already represented must be re-represented in a parallel system to support conscious access.
      ?

      Think about whether this reason is strong or weak

    • 2.This perspective generates an assumption that the processes supporting personal-level thinking are linear — i.e., that earlier representations are directly available to later personal-level cognition.
      ?

      Think about whether this reason is strong or weak

    • 3.This assumption about linearity of personal-level processes is what drives the early/late debate's errors.

      Think about whether this reason is strong or weak

    Reasons Against

    Reason against 1 of 2
    ?
    • 1.Broadbent's original filter theory was explicitly motivated by capacity limits in neural channels, not assumptions about personal-level cognitive architecture.
      ?

      Think about whether this reason is strong or weak

    • 2.If the early/late debate originates in empirical constraints on neural bandwidth (Cherry 1953, dichotic listening), then linearity of personal-level processing is a downstream inference, not the generative assumption.
      ?

      Think about whether this reason is strong or weak

    • 3.Mislocating the source of theoretical error in personal-level assumptions rather than neural modeling obscures the actual empirical stakes of the debate.

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Treisman's attenuation model and Deutsch-Norman late selection theory disagree specifically about when neural representations become available to response systems, not about personal-level linearity.
      ?

      Think about whether this reason is strong or weak

    • 2.If rival theorists share no common assumption about personal-level process linearity yet still generate the early/late debate, then that assumption cannot be what drives the debate's problems.

    Key Terms

    early/late debate(Cognitive psychology; specifically the question of whether selection occurs before or after semantic processing)
    The debate between early selection theory and late selection theory about the stage in perceptual processing at which unattended information is filtered out.
    linearity(as used in philosophy of mind)
    The quality of following a straight, step-by-step sequence where one thing directly causes the next in a simple, predictable way.
    neural processing(as used in philosophy of mind and neuroscience)
    The activity and information-handling that happens inside the brain and nervous system at the biological level.
    personal-level thinking(as used in philosophy of mind)
    The mental processes and thoughts that happen at the level of a whole person, as opposed to what's happening in individual brain cells or neurons.

    A reason why assumptions about linearity may have been problematic is that when, following Broadbent, we think about hierarchical perceptual processing while bearing in mind the communications engineer’s concerns about capacity limitations, it then becomes natural to make some additional assumptions about the way in which this hierarchically organized architecture supports personal-level cognition. The early/late debate’s problems are more plausibly blamed on these additional assumptions, rather
