Spaun performing copy drawing. The model is presented the image, and then must try to reproduce the visual features of the presented image from memory. The top video shows Spaun reproducing a '2' with a looped bottom. The bottom video shows Spaun reproducing a '2' with a straight bottom.
For this copy drawing task, the Spaun model must reproduce the perceptual features of the input using its motor system. Here, both of the inputs are the number 'two', but they are drawn in two different styles. The first has a looped bottom, and the second a straight bottom. Spaun's ability to capture these differences with its motor responses shows that its neural representations carry deep semantic features of its input.
