My Wife and My Mother In Law

The “My wife and my mother-in-law” illusion is an optical illusion with an image of a young woman’s face that can also be perceived as an older woman’s face.

The illusion is created by the way the brain organizes the visual information in the image, and how it interprets the relationships between the different features of the face.

How does the My Wife and My Mother In Law Illusion work?

The “Wife and Mother-in-Law” illusion works by exploiting the way the human visual system processes and interprets facial features and their relationship. The illusion is based on a drawing created by the Swiss psychologist Roger Shepard, that shows a young woman’s face in profile view. However, by slightly adjusting the position of the features, the same image can also be perceived as an older woman’s face in profile view.

The illusion works by playing with the viewer’s expectations about the relationships between the different facial features. When the image is perceived as a young woman, the viewer’s brain organizes the information in a way that highlights the similarities between the different features, and creates a coherent, meaningful interpretation of the face. When the image is perceived as an older woman, the viewer’s brain organizes the information in a way that highlights the differences between the features, and creates a different coherent, meaningful interpretation of the face.

This illusion also highlights the importance of context and the role of prior knowledge and expectation in perception. The brain uses prior knowledge and expectations to make predictions and hypotheses about what it is seeing, and this can influence how it interprets ambiguous or conflicting visual information.

Additionally, this illusion is also related to the concept of “perceptual set” which refers to the brain’s ability to focus on specific aspects of the image and ignore others depending on the context. Also, the concept of “top-down processing” where the brain uses prior knowledge to interpret the visual information coming from the eyes.
