The reinforcement learning model (Holroyd and Coles, 2002) argues that a feedback ERN is generated when the feedback is worse than expected. In the current experiment, we investigated whether the reinforcement learning system was also activated by unexpected feedback in a task in which feedback was not necessary to perform properly. A flankers task, in which false negative feedback was presente...

The effect of providing error-flagging support during tests was studied in spring 2009 with two tutors on while and for loops. A partial crossover design was used for the study and mixed-factor ANOVA was used to analyze the students’ score per problem, number of revised problems, effect of revision on score and time spent per problem, and finally, the effect of errorflagging on adaptation and l...

This paper proposes a necessary and sufficient condition of convergence in the 2 L norm sense for a feedback-based iterative learning control (ILC) system including a multi-input multi-output (MIMO) linear time-invariant (LTI) plant. It is shown that the convergence conditions for a nominal plant and an uncertain plant are equal to the nominal performance condition and the robust performance co...

We develop a communication-efficient distributed learning algorithm that is robust against Byzantine worker machines. propose and analyze gradient-descent performs simple thresholding based on gradient norms to mitigate failures. show the (statistical) error-rate of our matches Yin et al. (2018...

The human visual system adapts to the changing statistics of its environment. For example, the light-from-above prior, an assumption that aids the interpretation of ambiguous shading information, can be modified by haptic (touch) feedback. Here we investigate the mechanisms that drive this adaptive learning. In particular, we ask whether visual information can be as effective as haptics in driv...

anxiety disorders are the most common reasons for referring to specialized clinics. if the response to stress changed, anxiety can be greatly controlled. the most obvious effect of stress occurs on circulatory system especially through sweating. the electrical conductivity of skin or in other words galvanic skin response (gsr) which is dependent on stress level is used; beside this parameter pe...

Obsessive-compulsive disorder (OCD) patients show hyperactive performance monitoring when monitoring their own actions. Hyperactive performance monitoring is related to OCD symptomatology, like the unflexibility of compulsive behaviors, and was suggested as a potential endophenotype for the disorder. However, thus far the functioning of the performance monitoring system in OCD remains unclear i...
