Gibson also argued that perceptual experimenters were misguided in their control over physical variables of stimuli, and the display of stimulus information should be manipulated instead. This stance breaks from traditional thought in that Gibson posited that fundamentally sound experiments could be conducted in the external world without having to construct artificial laboratory settings.
