Psychology of Climate Change

We explore how human cognition, emotions, and motivations shape our responses to the climate crisis, with the aim of fostering more sustainable behaviors and policies. Our research in this area examines how to motivate and reinforce climate action using behavioral interventions such as framing, happiness, probabilistic rewards, and feedback. We also examine the cognitive foundations and biases of climate change to help inform the development of new interventions. Together, our work reveals the psychological levers that can be used to inspire high-impact and lasting climate action.

Sustainability Interventions

Our research here focuses on designing and testing novel behavioral interventions that promote sustainable practices in everyday life. We investigate how psychological principles can be applied to encourage pro-environmental behaviors such as reducing waste, conserving energy, and making sustainable consumer choices. Our work examines the effectiveness of various intervention strategies, from nudges and incentives to educational campaigns, across diverse contexts including hospitals, botanical gardens, and community settings.

Biodiversity Conservation

We investigate the human dimensions of biodiversity conservation, examining how people perceive, value, and interact with wildlife and socio-cultural ecosystems. Our research explores the psychological factors that influence conservation attitudes and behaviors, including the role of cultural ecosystem services, human-animal relationships, and conservation messaging. We study how to effectively communicate conservation goals and mobilize public support for protecting endangered species and preserving biodiversity with diverse segments of the audience.

Cash Transfer Interventions

Our research examines how unconditional cash transfers can reduce poverty and homelessness, improving economic, social, and well-being outcomes of recipients. We investigate the behavioral and psychological effects of unconditional cash transfers and basic income, exploring how financial support influences decision-making, well-being, and life trajectories in low-income individuals in North America. We also examine the costs and benefits of cash transfers and various models of basic income, to help inform poverty-reduction policies and programs.

Financial Decision Making

We study how scarcity and financial constraints impact cognitive function and decision-making processes. Our research explores the psychological mechanisms through which scarcity influences attention, memory, and executive functioning. We investigate how these cognitive effects impact financial choices, future planning, and overall well-being, with implications for designing better financial products and policies for low-income populations.

Statistical Cognition

We investigate how people perceive, learn, and reason about statistical regularities in the environment. Our work explores the cognitive mechanisms underlying statistical learning, including how the mind automatically extracts regularities from sensory input and uses this information to guide attention, perception, and decision-making. We study how statistical knowledge influences everything from visual perception to probability judgments and belief formation.
