Marcos Nadal holds a PhD in Human Cognition and Evolution from the University of the Balearic Islands. His doctoral thesis, defended in 2007, explored the effects of different kinds of visual complexity on aesthetic valuation of artistic and non-artistic visual stimuli. Since then he has been involved in neuroscientific and evolutionary studies of human cognition, especially aesthetic valuation. His current research aims to understand the relations between the cognitive processes, neural mechanisms, and evolutionary events that have endowed humans with the capacity for aesthetic valuation.
