This study shows that maternal body odor enhances visual face categorization in 4-month-olds only when visual demand is high, supporting inverse effectiveness in olfactory-to-visual facilitation.

The paper shows that the facilitative effect of maternal odor on face categorization in infants decreases from 4 to 12 months, correlating with improved visual processing.

This study shows that body odor enhances neural responses to ambiguous facelike objects in the visual cortex, suggesting olfaction aids visual categorization.

The paper uses EEG to show that neural responses to facelike objects predict conscious face perception, with stronger responses in those who report seeing illusory faces.
