Even though end-user participation in requirements engineering (RE) is highly important, it is at present not frequently used. Reasons can be found in the large expenditure of time for organizing and carrying out surveys as well as in the time it takes to understand the users’ requirements. This research is supposed to address this problem by presenting the(More)
End-user participation in requirements engineering (RE) is important, but not frequently used at the moment. Reasons are the large expenditure of time for organizing and carrying out surveys as well as the time it takes to understand the users¿ requirements and to formulate them textually. But even textually formulated requirements are not sufficient, as(More)
Within one experiment and one T-maze, we examined the consequences of (i) bilateral lesions of the anteromedial prefrontal cortex (PFC), (ii) bilateral transections of the fimbria-fornix (FF), or (iii) combined lesions of both PFC and FF (COMB) on rats' ability to perform reversal or set-shifting. Postoperatively, the animals were trained to perform a(More)
UNLABELLED When gathering valued goods, risk and reward are often coupled and escalate over time, for instance, during foraging, trading, or gambling. This escalating frame requires agents to continuously balance expectations of reward against those of risk. To address how the human brain dynamically computes these tradeoffs, we performed whole-brain fMRI(More)
Even though build automation tools help to reduce errors and rapid releases of software changes, use of build automation tools is not widespread amongst software practitioners. Software practitioners perceive build automation tools as complex, which can hinder the adoption of these tools. How well founded such perception is, can be determined by systematic(More)
Adaptive actions build on internal probabilistic models of possible outcomes that are tuned according to the errors of their predictions when experiencing an actual outcome. Prediction errors (PEs) inform choice behavior across a diversity of outcome domains and dimensions, yet neuroimaging studies have so far only investigated such signals in singular(More)
Decisions are based on value expectations derived from experience. We show that dorsal anterior cingulate cortex and three other brain regions hold multiple representations of choice value based on different timescales of experience organized in terms of systematic gradients across the cortex. Some parts of each area represent value estimates based on(More)
BACKGROUND Depressed individuals often exhibit impaired inhibition to negative input and identification of positive stimuli, but it is unclear whether this is a state or trait feature. We here exploited a naturalistic model, namely individuals with seasonal affective disorder (SAD), to study this feature longitudinally. AIM The goal of this study was to(More)
