Approximately 800 participants were recruited by researchers visiting a high-profile Technology & Innovation Expo to investigate screen-time habits and digital working memory capacity. The researchers used a cross-sectional design for their study, grouping the participants into key age brackets after testing.
To measure digital working memory, participants completed a spatial recall task on a tablet where they had to remember the positions of 12 different icons on a grid. The grid appeared for 5 seconds before disappearing, and participants had to tap the correct locations. The researchers tracked accuracy and response latency.
To measure daily screen-time, participants self-reported the total duration (in hours and minutes) they spent using digital devices (such as smartphones, tablets, or computers) over the previous 48 hours for leisure purposes.
