Document Summary
Percentage correct detections is higher on the shadowed channel but not zero on the unattended channel. Consistent with the filter attenuating the stimuli instead of blocking them: criticisms of early selection of before, late selection and access to long term memory, early and late selection theories both agree that recognition needs both encoding. Filter is too complex -> involves response to semantic context & distinguishing related from unrelated stimuli (requires semantic knowledge) Top-down selection by pertinence (related to awareness. Still need to pass through the filter for awareness having pass through filter: norman (1968) Bottom-up and top-down selection mechanisms behavioural goals and purpose; expectations) Both kinds of activation are need to get through the filter, otherwise the stimulus will decay: evidence for late selection. Shadowing task (attended channel) passage with an ambiguous sentence. Unattended semantic words meaning the to ambiguous sentence (bank = river bank or bank = financial institution) with related channel the passage.
