In Tsushima, Sasaki, & Watanabe (2006), research findings show that task-irrelevant sub-threshold motion can significantly disrupt task performance compared to supra-threshold motion. The study reveals that sub-threshold motion leads to higher visual cortex activity but lower lateral prefrontal cortex activity. These results emphasize the potent effect of unconscious stimuli on conscious processing, bypassing inhibitory control mechanisms. Explore related studies on mirror neurons for automatic unconscious knowledge of others' intent at the neuronal level.

Automatic unconscious knowledge- Tsushima, Sasaki, & Watanabe (2006). Science, 314. • 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 supra-threshold 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. • See also research on mirror neurons (automatic unconscious knowledge of the intent of others at the neuronal level)
