Previous studies revealed that internet addiction make human intelligence and cognitive abilities worse. In this study, we tried to find out how much worse using correlation analysis. K-Young test used for measuring the degree of addiction, and several behavioral experiments used for measuring intelligence and cognitive ability. Participants were a total of 300 people, and 29 people on the potential risk was included. As a results, there was a significant correlation between degree of internet addiction and working memory’s recall accuracy, visual attentional resource allocation ability, mental-attentional capacity, and mental rotation ability. And there was no significant correlation between addiction degree and motion control ability, emotional perception ability, and intelligence. This results shows that the internet addiction's harmfulness about inteligence and cognitive ability is still not certain.
