<human>:  When was the first psychology lab built?
<bot>: The first psychology lab was built in 1879 by Hermann Ebbinghaus. Ebbinghaus was a German psychologist who is most famous for his memory experiments. He developed the "forgetting curve," which shows that the amount of information that can be remembered in a short period of time decreases exponentially as the amount of time increases. This means that if you want to remember a large amount of information, you need to study it for a long time.
