Those letters imagines were also the mirror images in vary ways of true letters. The experiment was to report whether the letter was normal or mirror-imagine. It was easy to conclude that people will take longer time to recognize the letter that was rotated. And the results of their experiment was the more the letter was rotated, the much time people need to decide what kind of rotating the letter images was. Shepard and Metzler are known for the creation of aspects that are vital in the study of angular disparity mirror imaging effects. In the studies using 3-D and 2-D stimulus, Shepard reiterates that mirror imaging is critical in cognitive reasoning and finding solutions to psychological problems (Thomas 4). Additionally, the researchers assert that mental rotation is a behavioral phenomenon that relates to neural processes and simplifies the understanding of brain structures that encompass angular disparity. After Shepard&Metzler’s experiment, Carpenter and Eisenberg assumed spatial representation contributed mental rotation a lot and they designed a experiment about mental rotation on blind and sighted individuals.

The viewpoint cost that is the shortest path for two rotating stimuli is affected by the angular disparity and mirror imaging through the variation of observers' perspectives regarding recognizable objects (Cheung 129). Mirror imaging reduces the look and identification of objects presented in 3-D formats. Consequently, mental rotation is influenced by the impacts of angular disparity through the changes observed in identity judgments and spatial
