The opportunity cost of time modulates cognitive effort – a replication study of Otto & Daw (2019) Neuropsychologia
Lead Researcher: Floortje Spronkers
Study: replication study of the Simon task with fluctuating average reward rate used by Otto & Daw (2019). The original study showed that when the average reward rate in the environment (an estimate of the opportunity cost of time) is high, people are less accurate and faster than when the average reward rate is low, indicating less cognitive effort expenditure. The current study aims to replicate this finding in a student population in the lab, in contrast to the online population used by Otto & Daw (2019).
Psychiatric symptom dimensions and their relevance for motivational biases in decision making - A computational perspective
Lead Researcher: Dr. Vanessa Scholz
Study: The goal of this study is to investigate the association between motivational biases in decision-making and transdiagnostic psychiatric symptom dimensions. Using online data collection, factor analysis and computational modelling we want to explore whether transdiagnostic compulsive and obsessive symptoms are uniquely linked to increased motivational biases that could produce the repetitive behavioral patterns we see for example in OCD patients.
