Study description

Delay discounting of smartphone use: Trait moderators and the effects of episodic future thinking

This research aims to understand how people make decisions about smartphone use and whether a short imagination exercise, called Episodic Future Thinking (EFT), can help reduce the tendency to choose 'phone-now' over 'phone-later.' The study also explores whether smartphone-specific decision tasks are better predictors of real-world phone use than money-based tasks.
