The "Mozart Effect" is a term that refers to a set of research results that indicate that listening to Mozart's music may induce a short-term improvement on the performance of certain kinds of mental tasks known as "spatial-temporal reasoning." This idea became popular in the early 1990s, and while the original studies had limitations and the concept has been debated, it sparked interest in the potential cognitive benefits of music. However, it's essential to note that the broader claims of long-term intelligence enhancement attributed to the Mozart Effect have been largely debunked.
