Approximately 1,200 participants were recruited by researchers visiting a national Technology Museum to investigate digital distractions and cognitive switching performance. The researchers used a cross-sectional design, grouping participants into age brackets.
To measure switching ability, participants completed a highly standardized task on a tablet where they had to classify 20 simple geometric shapes. They either categorized the shape (e.g., triangle vs. circle) or its color (e.g., red vs. blue) based on a high-pitched or low-pitched tone cue. The software recorded accuracy and response latency.
To measure daily distraction habits, participants completed a brief structured questionnaire asking how many hours they had spent using multiple media screens simultaneously in the past 24 hours.
