Experimental psychology evolved in 19th century Germany. Figure 23.1 shows three of the key scholars involved.

Why were they all men?

Women were simply not allowed to study! In Germany, women were only allowed to matriculate at universities starting between 1900 and 1909 (depending on the Bundesland). A notable, but also singular, exception was Dorothea Erxleben.

In England, the first degrees for women were awarded by the University of London in 1878 (although Oxford only followed suit in 1920 and Cambridge in 1948!). Beatrice Edgell was the first female psychology professor in the UK. She was appointed in 1927 by the University of London.

Before the advent of experimental psychology, psychological theorising had been the purview of philosophers. Unfortunately, while coming up with some ideas highly relevant to psychology (see, e.g., John Locke, David Hume and John Stuart Mill), they were not interested in testing their ideas empirically.

In 19th century Germany, the physiologists mentioned above1, among others, took a different approach and started to perform experiments to empirically test ideas relevant to the nascent field of psychology.

Among his many other contributions to science, in 1849 von Helmholtz measured neuronal conduction speeds and showed that, while neuronal conduction was fast (about 25 to 40 m/s in frog neurons), it was not so fast that it could not be measured.2 This insight opened the door to investigating the human mind by measuring the time it took to complete certain tasks.

Fechner on the other hand, building on the work of Ernst Heinrich Weber, established the field of psychophysics.

And, in 1879, Wundt founded the first psychological institute in the world at the University of Leipzig. According to Boring (1950), he should be considered the first psychologist.

  1. Notably, Fechner, von Helmholtz and Wundt had all studied medicine, not philosophy. That said, they were not just physiologists or psychologists. Boring (1950) notes that Fechner “was for seven years a physiologist (1817-1824); for fifteen a physicist (1824-1839); for a dozen years an invalid (1839 to about 1851); for fourteen years a psychophysicist (1851-1865); for eleven years an experimental estheticist (1865-1876); (…) recurrently and persistently a philosopher (1836-1879); and finally, during his last eleven years, an old man whose attention had been brought back (…) to psychophysics (1876-1887)” (p. 283). Von Helmholtz was also an eminent physicist. And Wundt was also a philosopher.↩︎
