Tech Tuesday Talks

Tech Tuesday Talks is a monthly seminar series bringing together researchers from across the USC campus who share interest in technology-assisted health promotion and disease prevention interventions and research.  The series presents a forum to learn about one another’s work, spark collaborations as well as to introduce students to the ongoing research conducted on the USC campus which incorporates technology in health promotion.  All interested faculty and students are invited to attend.  The event is free and open to the public.

Tech Tuesday Talks are presented on the fourth Tuesday of the month in Discovery I Building, Room 140 at noon.  Lunch will be available for the first 20 arrivals and you may also bring your own lunch with you. For more information contact Karen Magradey at (803) 777-3471 or

Flex-An App that Applies Associative Learning Theory with Gamification to Target Non-Conscious Physical Activity Behavioural Biases


Amanda Rebar, PhD

Most physical activity interventions provide compelling reasons to be active based on the premise that persuasion is the most effective way to change behaviour. However, evidence based on dual process models show that physical activity behaviour is more than just the translation of attitudes, values, or goals. The automatic urges people feel to approach or avoid certain actions are the result of automatic associations people hold in their procedural memory. For example, some people automatically associate the concept of physical activity with being good and therefore tend to approach opportunities to be physically active more often. FLEX is a unique mobile app-based physical activity intervention because it targets these automatic associations; thereby enhancing physical activity behaviour discretely. Along with this theory-based approach to changing behaviour, FLEX applies gamification to encourage high engagement and retention. Our pilot data suggests that FLEX can improve the way we target health behaviour promotion efforts.
