Dr. Yasmina Okan is a Cancer Research UK Fellow and Associate Professor in Behavioral Decision Making at the Centre for Decision Research. She holds a PhD in Experimental Psychology from the University of Granada (Spain). She has been a Visiting Researcher at different international institutions, including the Max Planck Institute for Human Development (Germany) and the Michigan Technological University (US).
Yasmina’s research focuses on the psychology of judgment and decision making, with an emphasis on health risk perception and communication. Her work is currently supported by Cancer Research UK, the largest independent funder of cancer research in Europe. The goal of her CRUK-funded project is to improve public communications about cervical cancer screening. She has also worked on multiple projects examining how to improve communications about different health risks using simple graphs, and how to measure individual differences in graph literacy. Previous and ongoing projects have been supported by grants from the US Informed Medical Decisions Foundation, the Worldwide Universities Network, and the Spanish Ministry of Education and Culture. Her research has been published in leading academic journals including Journal of Behavioral Decision Making, Journal of Experimental Psychology: Applied, Medical Decision Making, Risk Analysis, Quarterly Journal of Experimental Psychology, and Vaccine. She also been the recipient of awards including the Jane Beattie Memorial Travel Scholarship from the US Society for Judgment and Decision Making. Her research interests also include moral judgment and decision making, and climate risk perception and communication.
Yasmina has also received awards in recognition of excellence in teaching, including the Dean’s Award for Teaching Excellence (2015) and the Management Division Teaching Award (2016) from Leeds University Business School. She is a Fellow of the UK Higher Education Academy, in recognition of attainment against the UK Professional Standards Framework for teaching and learning support in higher education.
In order to make informed decisions people need to understand information about risks, benefits, and harms of different options. Inadequately designed risk communications may not only be unhelpful, but can also lead to important errors in comprehension and mislead decision makers. My research has focused on examining the use and misuse of different formats to communicate risks (e.g., graphical displays), and the effect of such formats on people’s judgments and decisions. Ultimately, I hope to achieve a comprehensive, theoretically-grounded, understanding of how to improve the design of risk communications among individuals with varying levels of graph literacy and numeracy.
Examples of my work include studies examining the effectiveness of graphical displays to reduce common judgment biases (Okan et al., 2012, 2015) and the impact of different graphical design features on people’s understanding of health risks and associated decisions (Okan et al. 2016, 2018a, 2018b, under review). My colleagues and I have also developed a short scale to assess individual differences in graph literacy (SGL scale; Okan et al., in press). The scale items can be accessed here.
My CRUK-funded work has examined how cervical cancer screening information is communicated in UK websites, how women interpret the NHS cervical screening leaflet sent to women across England, and what is the prevalence of misunderstandings. I have shared preliminary findings with Public Health England to inform the design of new versions of the leaflet. Planned work will examine how to improve communications about benefits and risks of cervical screening using simple graphs. In ongoing projects I am investigating how to improve the design of graphical health risk communications in a range of different domains.
In additional projects I have also examined contextual and emotional factors affecting people’s moral judgments and decisions, including the temporal order in which different moral dilemmas are evaluated (Wiegmann et al., 2012), the effect of different types of emotions (De la Viña et al., 2015), and age-differences in moral judgement (McNair et al., 2018). I am also interested in factors shaping public perceptions of climate change risks.
My collaborators include colleagues across the University of Leeds, as well as international institutions such as the Harding Centre for Risk Literacy (Germany), the Santa Fe Institute (US), Wake Forest University (US), the Washington School of Medicine (US), the Andalusian School of Public Health (Spain), and the University of Oklahoma (US), among others.
