ABSTRACT
Is psychology a global field? Naturally. From its very origins in 1879, it is remarkable how our modern “science of behavior and mental processes” energetically fanned out with Wilhelm Wundt’s students within 10 years to all corners of the globe, from the U.S. to Australia, Chile, and Japan (Fernberger, 1933; Lamberti, 1995; Misiak & Sexton, 1966). Yet, for much of the 20th century, just one nation, the U.S., has contained over half of all the world’s psychologists (Rosenzweig, 1984). This balance tipped in the 1990s, as our fast-growing field now grows even faster across Europe and other nations, making psychology more global than ever before (see Chap. 2 and 3).1
