In 1861, Hering described an [[optical illusion]] which now bears his name – the [[Hering illusion]]. When two straight and parallel lines are presented in front of radial background (similar to the spokes of a bicycle), the lines appear as if they were bowed outwards. The [[Orbison illusion]] is one of its variants, while the [[Wundt illusion]] produces a similar, but inverted effect.

Hering first suggested the idea of [[organic memory]] in an 1870 lecture for the Imperial Academy of Science in [[Vienna]]. Hering took influence from the idea of [[inheritance of acquired characteristics]] and suggested that memories could be passed on through generations by [[germ cell]]s.<ref>Stanley, Finger. (1994).
