Does tv lower IQ

Answer 1

Even with the knowledge gained from research focused on television's ability to teach specific skills, the medium is frequently castigated for interfering in the education of children. Achievement, intellectual ability, grades, and reading show complex relationships with television viewing. For example, the relationship between television viewing and academic performance is not clear cut. Children who spend a great deal of time watching television do poorly in school but children who spend a moderate amount of time with TV perform better than non-viewers. The small negative relationship between IQ and television viewing masks some important subgroup differences, such as age (high IQ is positively correlated with viewing until the teens) and gender (with the negative relationship holding stronger for boys than for girls). Reading and television viewing are positively correlated up to a threshold of about ten hours of viewing per week. Only when television viewing rises above a certain level does it seem to be related to less reading. Overall, the data suggest that television has a small adverse effect on learning.
