Spatial and contextual factors in human performance on the travelling salesperson problem.

abstract：:Embodied cognition and perceptual symbol theories assume that higher cognition interacts with and is grounded in perception and action. Recent experiments have shown that language processing interacts with perceptual processing in various ways, indicating that linguistic representations have a strong perceptual charac...
