What aspect of perception is primarily focused on cultural differences in visual illusions?

The focus on cultural differences in visual illusions is best understood through cultural context. Visual illusions are experienced based on the interpretation of sensory information, which can vary significantly across different cultures. Cultural context influences how individuals perceive and interpret visual stimuli. For instance, particular shapes, colors, or spatial arrangements may carry different meanings or significance in various cultures, leading to variations in how illusions are perceived.

Different cultural backgrounds can involve varying experiences, traditions, and environmental influences that shape an individual's cognitive and perceptual processes. Hence, it is through the lens of cultural context that one can best analyze the diversity in reactions to visual illusions, underscoring the importance of culture in shaping perception. This perspective helps to explain why individuals from different cultural backgrounds might experience and interpret the same visual stimulus in distinct ways.
