Manifestations of impulsivity in everyday life
Decision making during a pandemic
Van Baal, S. T., Walasek, L., & Hohwy, J. (2021, February 26). Staying home so you can keep going out: A multiplayer self-isolation game modelling pandemic behaviour.
We use a game-theoretical approach to see how people respond to changes in their environment during the pandemic. We see that people display illusory superiority, rely strongly on social norms, and respond too late to increasing disease prevalence.

We explore the effects of administering daily episodic future thinking and compassion training prompts on people's urges to thwart public health restrictions using an experience sampling (ecological momentary assessment) paradigm. We find that people experience weaker urges in both conditions compared to the control group.
We see whether communicating with the public through using prescriptive language or calls for personal responsibility is more effective at changing people's attitudes to leaving the house in specific scenarios.

We test whether a chatbot equipped with behaviour change interventions can alter people's intentions to get tested.

We demonstrate how chatbots may be used to deliver behavioural interventions. Introducing Cory COVID-bot, a friendly librarian who is knowledgeable about COVID-19 and who recommends animations to users. These animations elicit compassion and attempt to reduce exponential growth bias. This novel approach to changing behaviour will be useful for researchers and mHealth practitioners.
