Identifying shape transformations from photographs of real objects.

ABSTRACT: An important task of human visual cognition is to make inferences about properties of objects. One such property is an object's causal history: what happened to the object in its past (e.g., "this paper has been folded"). There is relatively little research on whether and how we make such inferences. We took photographs of objects from six different materials ('wax', 'aluminum foil', 'gold foil', 'chicken wire', 'putty', 'cardboard') transformed by one of four shape-altering transformations ('folded', 'bent', 'crumpled', 'twisted'). By varying execution of transformation and viewpoint, we obtained 30 images of each material/transformation combination (720 images). We asked different groups of participants to: (1) name transformations and materials, (2) rate images with respect to the exten
