• Task-irrelevant sub-threshold coherent motion (irrelevant
signals) led to a stronger disturbance in task performance
than did supra-threshold motion (ineffective inhibitory
control).
– With the sub-threshold motion, activity in the visual
cortex (measured by fMRI), was higher, but activity in the
lateral prefrontal cortex was lower, than with suprathreshold motion. These results
• Summary: Unconscious and unattended information can
escape inhibitory control exerted by frontal areas and
influence conscious processing of stimuli more powerfully
than conscious stimuli.
