Frequent internet use is associated with better episodic memory performance.

As the internet is becoming more and more accessible and prevalent, there has been growing interest in determining the effect of internet use on human cognition, particularly memory. However, much less is known about how internet use frequency is related to episodic memory, which refers to the memory of past events as opposed to facts (i.e., semantic memory). Episodic memory is very relevant to the internet because of the notion that the internet is a form of transactive memory, which requires people to retrieve how information was accessed (i.e., episodic memory) rather than the information itself (i.e., semantic memory). By analyzing data from 36, 542 participants with 44.06% females and a mean age of 46.63 years old from the Understanding Society using multivariate and univariate analysis of variances (ANOVA), the current study found that the frequency of internet use is positively related to episodic memory (assessed using the immediate recall and delayed word recall tasks). These results provide support to the notion that the internet is a form of transactive memory and the "use it, or lose it" theory.
