Performance monitoring at the task and the response level

How errors and confl ict are processed in the human brain, has been extensively investigated over the last decades. In this review, we argue that error research has mainly focused on one type of errors, namely errors at the response level. Furthermore, research on conflict and errors has primarily used a very restricted set of experimental paradigms, raising the question as to whether the results from this research can be generalized to other forms of errors and confl ict. We thus argue to approach errors and confl ict from a broader perspective

Strategy changes after errors improve performance

The observation that performance does not improve following errors contradicts the traditional view on error monitoring (Fiehler et al., 2005; Núñez Castellar et al., 2010; Notebaert and Verguts, 2011). However, recent findings suggest that typical laboratory tasks provided us with a narrow window on error monitoring (Jentzsch and Dudschig, 2009; Desmet et al.,2012). In this study we investigated strategy-use after errors in a mental arithmetic task. In line with our hypothesis, this more complex task did show increased performance after errors. More specifically, switching to a different strategy after an error resulted in improved performance, while repeating the same strategy resulted in worse performance. These results show that in more ecological valid tasks, post-error behavioural improvement can be observed

Simulation of the flow-acoustic-structural interaction in flow ducts using a partitioned approach in the time domain

Duct systems confining a subsonic air flow, such as ventilation ducts, often have a lightweight design. These lightweight constructions are easily excited by unsteady pressure fluctuations in the flow, causing structural vibrations and noise emissions. Designing effective solutions for this flow-acousticstructural problem requires a better understanding of the multi-physical interactions and efficient prediction tools. In this work, due to the confined configuration, the vibro-acoustic interaction is a strong two-way interaction and is modeled by coupling a flow-acoustic solver with a structural solver. The kinematic and dynamic continuity at the interface is ensured in this partitioned approach by a data exchange during runtime between the solvers. The data exchange is managed by the open-source coupling library preCICE [1]. The analysis of the flow-acoustic-structural interaction in a flexible flow duct with rectangular cross section was given in [2]. In this paper, the error resulting from the pressure mapping between both solvers is analyzed and an improved force mapping strategy is adopted
