Abstract: Nineteen middle-school aged students visiting a planetarium were presented with three types of spatial cognition tasks using both two-dimensional (flat) and stereoscopic representations. The students' performance on tasks was evaluated in order to determine the impact of stereoscopic presentation upon accuracy and task completion time. Results show that accuracy did not differ between the two representational types while completion time was greater for the stereoscopic representations. Post task interviews show that students continued to think of the stereoscopic spatial tasks as two-dimensional. Results were analyzed through the lenses of cognitive load and cue theory. %[ 2022-06-08 %~ Tufts Digital Library %W Institution
