    Broadbent was wrong to suppose that the psychological effects of unattended stimuli can only depend on properties of which the inattentive perceiver can be aware.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Subliminal priming studies (Dehaene et al. 1998) demonstrate that masked stimuli alter behavior without reaching conscious threshold.
      ?

      Think about whether this reason is strong or weak

    • 2.If unattended stimuli causally influence behavior via non-conscious pathways, their effects cannot be constrained by awareness conditions.
      ?

      Think about whether this reason is strong or weak

    • 3.Broadbent's filter model presupposes a single bottleneck, but parallel processing architectures allow stimulus effects prior to any awareness gate.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Marcel's (1983) dissociation experiments show semantic processing of stimuli subjects explicitly deny perceiving, evidencing sub-personal semantic effects.
      ?

      Think about whether this reason is strong or weak

    • 2.Any theory limiting unattended-stimulus effects to awareness-accessible properties cannot accommodate documented semantic priming without conscious access.
      ?

      Think about whether this reason is strong or weak

      Think about whether this reason is strong or weak

    • 2.The linearity assumption about the processes supporting personal-level awareness is false.

    Once the problematic assumption about linearity has been made precise, however, we see that it cannot be satisfactory to credit the entire collapse of the early/late debate to this assumption. The falsity of the assumption about the linearity of the processes supporting personal-level awareness does not undermine the very idea that the early/late debate is a meaningful one. The problems that it creates are largely methodological. The falsity of that assumption means that one cannot make an infer
