Three Psychotechnics Shadowscopes

Three Psychotechnics “Shadowscope” machines are arranged on tables in what appears to be a classroom or instructional space. Books are stacked beside the devices, and a wall poster titled “The Shadowscope” provides explanatory information. The Shadowscope was an educational viewing device developed by Psychotechnics, Inc., used to develop reading and perceptual skills. By controlling the viewer’s visual field and guiding eye movement across text, it was intended to improve focus, reading speed, and comprehension. Devices like these were part of mid-20th-century instructional experiments that emphasized mechanical tools for enhancing learning.
