Summary
The present paper presents an edited translation of the first doctoral thesis in experimental psychology, completed by Max Friedrich at Leipzig University during the Winter Semester of 1879–80. The official degree was awarded in 1880 and the full text was published in the first issue of Wundt's journal Philosophische Studien (Philosophical Studies). In addition to a translation of the original text, the author provides a critical analysis of the methodology and results of Friedrich within the context of modern psychophysics.
