American Professor Emeritus (retired) at the School of Psychology at the Georgia Institute of Technology, as well as the head of the Societate American pro Interlingua, and the editor of its quarterly journal, Confluentes. He was also the editor of the psychological journal Multivariate Behavioral Research for 8 years.
Interlingua is an Italic international auxiliary language (IAL), developed between 1937 and 1951 by the International Auxiliary Language Association (IALA). It ranks among the top most widely used IALs (along with Esperanto and Ido), and is the most widely used naturalistic IAL: in other words, its vocabulary, grammar and other characteristics are derived from natural languages rather than a centrally planned grammar and vocabulary.
In 2012 Mulaik published a book Interlingua Grammar and Method for The Use of the International Vocabulary As an International Auxiliary Language, which is available from Amazon.com and other vendors. The book is a detailed development of the grammar and sows his personal methods to determine the vocabulary, with several chapters on texts in Interlingua. The book also has 3248-word glossaries between English and Interlingua and Interlingua and English.
Mulaik lived in Salt Lake City, Utah from 1939 to 1966. Since then, he has lived in or around the Atlanta, Georgia area.
