21. Overconfidence and Format Dependence in Subjective Probability Intervals: Naive Estimation and Constrained Sampling
Abstract : A particular field in research on judgment and decision making (JDM) is concerned with realism of confidence in one’s knowledge. An interesting finding is the so-called format dependence effect which implies that assessment of the same probability distribution generates different conclusions about over- or underconfidence bias depending on the assessment format.

23. Aposematism, Crypsis and Population Differentiation in the Strawberry Poison Frog
Abstract : Evolutionary transitions between the two major predator avoidance strategies aposematism and crypsis are expected to be associated with changes in many important traits of animals. However, empirical studies on populations experiencing ongoing or recent transitions between these strategies are rare. READ MORE

24. Brain networks in time : deriving and quantifying dynamic functional connectivity
Abstract : Studying the brain’s structure and function as a network has provided insight about the brain’s activity in health and disease. Networks in the brain are often averaged over trials, frequency and time and this is called functional connectivity. This thesis aims to extend the analyses beyond these assumptions and simplifiations. READ MORE

25. Drug and disease effects on the human brain studied by functional MRI
Abstract : Background: With the advent of magnetic resonance imaging (MRI) technology, various functional MRI (fMRI) techniques have become available for non-invasive neuroscientific studies and clinical diagnostics, which have led to a better understanding of the human brain function in normal and diseased subjects. In order to interpret the fMRI results correctly and design optimal research studies it is important to understand both the potentials and limitations associated with each fMRI technique. READ MORE
