Research

General research interests.

I am interested in how healthy ageing affects personality and cognitive processes, such as learning and decision-making. So far, I've studied whether older adult risk-taking behaviour is due to age-related changes in personality (e.g., risk preference) and/or cognition (e.g., numeracy, working memory, processing speed), and whether collaborating with another person can be more beneficial to the learning performance of older adults (and under what circumstances).  

In addition to the above, I am interested in making research as reproducible and transparent as possible and conducting research in accordance with open science principles.  Below are several research topics that I am working on or interested in pursuing.

Collaborative learning in older age

Despite the process of learning often being studied individually, learning is often done with other people. We learn this way throughout life, from our younger years to older age. Ageing is associated with changes to cognitive abilities, which in turn affect the ability to storage and recall (new) information. However, the support and social aspect of learning with another person, such as a spouse, might benefit older adults' learning performance. As such, I investigate under what circumstances older adults learn better with another person versus alone; it may be that this benefit depends on the (existing) relationship between learning partners or the materials used. To learn more about this, my research focuses on the various aspects of collaborative learning, such as task performance but also on the interaction between pairs, such as the words they use or different strategies.

If this topic interests you, I would direct you to a recent systematic review on this topic, published in 2023 in Royal Society Open Science.

Applying Open Science principles to (aging) research

In my research, I aim to be as transparent as possible about my justifications, expectations, methods and results. To this end, I apply Open Science principles throughout my work. So far, every first author publication to my name is a Registered Report publication (August 2023), with the large majority of my work being Registered Reports or preregistered works. My study data and scripts are available on OSF where possible, including manuscripts and additional materials. I also share any slides or materials from talks and presentations on OSF. I am always happy to answer questions on how to incorporate Open Science principles into research, or any questions about my work.

Optimizing health care for older adults

In line with my interest in living healthily for longer, I am also interested in optimizing healthcare (for older adults). For example, the likelihood that we will take one or more types of medication to manage our health increases with age. With this, our chances of experiencing medication-related harm do too. Often, medication-related harm is unintentional and can be prevented. I am interested in how medication management for older adults can be optimised, and especially in identifying and addressing specific issues faced by older adults. This may be polypharmacy, unclear patient information leaflets (PILs), and other factors.
Another area of interest is minimising the pressure on healthcare providers, such as the National Health Service, through offering pre-clinical interventions. For example, connecting people with depression to local groups with research-supported activities that may address symptoms before medical intervention is required.

How (risky) decisions are shaped by cognitive abilities and personality

Life is accompanied by a variety of risks, from physical to financial. How different types of risk affect us changes with age, as some risks (physical) become more consequential than they were, or may have seemed, before. Despite the general assumption that older adults are risk averse, studies often find that older people do take risks, both in experimental settings and in daily life. So what drives these age differences in risky decisions? I am interested in whether age differences in risk-taking and risk perception are due to people's individual preference towards risk, or changes to cognitive abilities that may affect how we view and experience risk. 

If this is a topic that interests you, I recommend my 2021 publication on age differences and risky behaviours during the COVID-19 pandemic
