Holistic face perception - composite face effect
The Composite Face Illusion
The two top face halves on the figure on the right are strictly identical (just mask the bottom halves to see that). Yet they seem different.
Based on this compelling visual illusion, researchers have developed a widely used composite face paradigm in order to understand how facial parts are integrated into a unfied percept.
