"Over the past few years, a number of studies have reported on procedural similarities and differences between mental rotation and physical (i.e., manual) rotation of Shepard and Metzler-type stimuli. These similarities include comparable angular disparity effects and comparable final angular offsets in problem solving. This paper presents results from further comparisons based on gazed-derived measures obtained across the course of trials. In a within-subject design, participants solved the same tasks as mental and as physical rotation problems. We compare time courses of mean fixation duration and of saccade amplitude, and interpret these with respect to underlying mental processes and loads. The results point to additional specific procedural similarities and differences, which nicely complement the previous findings. The results are of additional, practical use for establishing how and when physical rotation can provide a useful proxy for mental rotation for purposes of process analysis, of ability assessment, and of training."
