A Case of Phenomenal Memorizing by a Feeble-minded Negro

Abstract

The case of a feeble-minded negro is described. He is chronologically 24 years and mentally between 8 and 9. He has a rather short auditory memory span failing on five digits. He has committed to memory a large array of facts about dates, places and locomotive engine numbers. Given a date—month, year, and day of month—he will give day of week. He cannot go back of 1901 nor forward beyond 1924. Between these limits he never fails. From Psych Bulletin 18:01:00034. (PsycInfo Database Record (c) 2024 APA, all rights reserved)
