The aim of this research was to explore the possible existence of any relationship between the constant use of online social networks and memory capacity of college students. The research, quantitative and with exploratory scope, was conducted in a private institution of higher education in Mexico. The study subjects were 51 college students from different programs. Surveys and tests of memory capacity as data collection tools were used. The results of the study indicate that there are no significant differences between the constant use of social networks and the memorization capacity of college students. Therefore, this study does not support the hypothesis that students who spend more time on social networks have a lower memory capacity.
