According to the text:

social science research warns that viewers must not watch sensationalist news programs.

Sesame Street research pointed out that most of the TV programs dedicated to children should focus on entertainment.

Sesame Street was proposed by altruistic motivations. In other words, the producers of the program did not have the intention of promoting children’s cognitive development.

the results presented in the text point out the positive and the negative aspects concerning the social effects of different entertainment options. The positive qualities are: relaxing and changing cultural attitudes. The second aspects are: misinformation of citizens and their lack of involvement with civic obligations.

cognitive ability is a characteristic that derives from biology, behavioral aspects, education, culture, and it nutrition and cannot be influenced by TV viewing habits.
