FTP, name this author of Memory: a Contribution to Experimental Psychology, a German known for his experiments with nonsense syllables and his learning and forgetting curves.
This man's experiments were made more rigorous by Friedrich Schumann and Georg Muller, who created a "drum" device to better display their visual stimuli. The possible influence of fatigue and inattention on this man's experiments were ruled out by Adolf Jost. The illusion named for this man, also known as Titchener circles, depicts a circle surrounded by other circles of varying sizes. His results important to pedagogic theory include the "serial position effect" regarding the order of items in a list, and the "spacing effect" which considers the most effective methods of study, but he may be best known for experiments with words such as "zof" and "wid".
