Both the reading and the lecture discuss about Mozart Effect, which is a theory that babies can improve their intelligence and creativity after listen to Mozart. The reading says that Mozart effect benefits positively, but the lecture against the reading.
First, the reading states that there's a study which supports the Mozart effect. According to the study, all participants improve their score after listen to Mozart. For example, in average 9 points of their IQ was added. Conversely, the lecture disagrees that in a study, test takers were college students, not a baby. Also, the effect was gone in 15 minutes.
Next, the reading argues that by Don Campbell, babies who listen to Mozart before they born are more creative than others who did not. According to the reading, this argument was so strong that some hospitals buy classic CDs. However, the lecture says that this argument has no actual scientific proves. In addition, since that argument became popular, it helps selling CDs. Thus, it's just a marketing tool.
To conclude, the reading and the lecture talked about the Mozart effect, which is listening Mozart helps babies more intelligent and creative. The reading argues that in a study, students get higher score after listen to Mozart, and by Don Campbell, babies are more creative if they listen Mozart in pregnant. On the other hand, according to the lecture, study was not in the appropriate condition, and the theory has no scientific basis, which became a marketing tool.
