While distractor inhibition can improve current selection, this mechanism can also impair later selection when the new and important information shares features with the old inhibited information. I extend previous preview-based research (Braithwaite & Humphreys, 2003) to more ecologically valid dynamic circumstances. This work reveals that the cost of feature sharing is greatly magnified when items move, compared to when items remain static. These findings implicate a flexible inhibitory weighting system, where the featural aspects of a display become more heavily weighted upon as spatial aspects become less reliable. This strongly implicates feature-based inhibition in real-world failures of visual awareness. In addition, I extend the negative priming effect to conditions far more complex than previous research has suggested is possible. This not only improves its ecological validity, but also reveals a strong similarity between negative priming and inhibitory carry-over effects of preview search. This finding questions previous claims that these paradigms recruit separate processes, implicating an overlapping inhibitory mechanism. In all, the current thesis places feature-based inhibitory processing in a far more central role of guidance, selection and failures of visual awareness than previous research has suggested.","abstract_html":"The thesis investigates the inhibitory processes of visual selection across time.
