High-resolution vision is limited to the center of our eyes-about a tenth of a percent of the entirety of our visual field-, but we perceive the whole visual field as a high-resolution, focused, perfectly formed image. Our brain makes up a large fraction of what we perceive. Illusory Contours and Filling-in Illusions in Dali's Art Visual illusions, present in many of the painter's artworks, include numerous examples of perceptual completion and ambiguous images. Thus, Dali's artworks challenge the viewers' perceptions of reality and enable them to see beyond the surface. He understood that we create an ordered or disordered world from intermittent and incomplete retinal information processed by our mind's experiences, desires and apprehensions. Salvador Dali intuited that what we construe visually as reality is the product of the habits of the mind, more than of the eye. Factors such as brightness, color, shading, and eye movements, among other contributors, can powerfully affect what we see. Many years before scientists began studying neuronal properties, artists devised multiple techniques to trick the brain into believing that a flat canvas had depth or that a sequences of brushstrokes was in fact a still life. Throughout history, artists and researchers have utilized illusions with the aim of understanding perception. Due to this disconnect between perception and reality, visual illusions exemplify how the brain fails to re-create the physical world, and provide vision scientists with substantial tools to apply to the study of the neural underpinnings of perception. When experiencing a visual illusion, we may see something that is not there in reality, fail to see something that is, or more generally see something different from what is there. Illusions are noted as the disconnect between physical reality and subjective perception ( Martinez-Conde and Macknik, 2010). Here we review the role of illusions in the art of Dali, focusing on the pieces displayed at the “Marvels of Illusion” exhibit.
The exhibition displayed a number of paintings, prints and sculptures by Salvador Dali (1904-1989), a sixteenth century piece from the School of Arcimboldo that was on loan from the Ringling Museum, and interactive demonstrations and illustrative material. Petersburg, FL., from June 14 to October 12, 2014, offered visitors a unique perceptual and cognitive experience into the world of ambiguity and illusions.
