Step-by-step explanation:
The first laboratory devoted exclusively to psychology as an independent field of study opened in Leipzig in 1879. Spearheaded by Wilhelm Wundt, often hailed as one of the founders of psychology, this laboratory marked a significant turn in the study of the human mind and behavior. Wundt's work at the University of Leipzig involved experimentation with reaction times, using introspection to analyze conscious experience, and helped psychology evolve from being an abstract philosophical pursuit to a more concrete scientific discipline.
