I’m a researcher at the Institute of Psychology at the Jagiellonian University. My main research interests are focused around motivation and goal-directed action, epistemic motivation, information processing, multitasking and multiple goal pursuit. I am also interested in extremism writ large (including extreme dieting, extreme sports, obsessive passions, extreme love and other forms of extreme commitment). Currently I am working on the project related to self-knowledge and motivational underpinnings of self-relevant feedback preference.
