People’s opinions differ as to whether too much time spent on watching TV and playing computers will negatively influence children's mental development. While I believe this can help exploit children's intelligence in some ways, the consequences of excessive using and watching cannot be ignored.
Though many parents blame the negative effects of watching TV and playing computer games on their children, screen-based technology like computer can build the player's brain the same way as learning to read, playing the piano, or navigating using a map. This is mainly because in many video games, the skills required to win involve following instructions, problem solving, logic thinking, hand-eye combination, fine motor and spatial skills. Also, adequate screen time allows a mass of exposures to visual stimulation, which can cultivate children's visual attention skills and image processing.
However, too much screen time regardless of what children watch or play may undo the gains we have discussed above, even resulting an imbalanced mental development. While children are able to develop their image-related skills, their literacy abilities may deteriorate as a result. This is especially true when we realize that many children who are addicted to screen-based technology are unable to concentrate on their studies if only text information is presented. While reading and writing long essays and journal articles are a core aspect of higher education assessment, the lack of mental focus as a result of computer and TV addiction will negatively influence children's academic performance.
In conclusion, though research into the long-term effects of screen time is still relatively young and we do not yet know exactly what effects playing video games, using computers, or watching TV has on childhood development, too much of anything may be counter-productive.
