The effect of error feedback on the accuracy of output task types such as editing task, text reconstruction task, picture cued writing task, and dictogloss task, has not been clearly explored. Following arguments concerning that the combination of both corrective feedback and output makes it difficult to determine whether their effects were in combination or alone, the purpose of the present st...

We numerically study the effect of additive Gaussian white noise in the dynamics of a time-delayed feedback system. The system is a semiconductor laser with optical feedback from a distant reflector. For moderate feedback levels the system presents several coexisting attractors, and noise levels above a threshold value induce jumps among these attractors. Based on the residence times probabilit...

Learning commonly requires feedback about the consequences of one's actions, which can drive learners to modify their behavior. Motivation may determine how sensitive an individual might be to such feedback, particularly in educational contexts where some students value academic achievement more than others. Thus, motivation for a task might influence the value placed on performance feedback an...

In the NLMS (normalized least mean square) adaptive filters, choosing a suitable step size is crucial as the stability and the steady-state convergence error of the adaptive filter heavily depends on the step size value. In this paper, we propose a new VSS (variable step size) control method for the NLMS adaptive filter applicable to on-frequency RF repeaters that operate under fading feedback ...

This paper extends the view of image processing performance measure presenting the use of this measure as an actual value in a feedback structure. The idea behind is that the control loop, which is built in that way, drives the actual feedback value to a given set point. Since the performance measure depends explicitly on the application, the inclusion of feedback structures and choice of appro...

People often evaluate money based on its face value and overlook its real purchasing power, known as the money illusion. For example, the same 100 Chinese Yuan can buy many more goods in Tibet than in Beijing, but such difference in buying power is usually underestimated. Using event related potential combined with a gambling task, we sought to investigate the encoding of both the real value an...

The purpose of this empirical research study was to investigate what motivates students to provide formative anonymous feedback to teachers regarding their perceptions of the teaching and learning experience in order to improve student learning. Expectancy theory, specifically Vroom’s Model, was used as the conceptual framework for the study. Multiple regression analysis was employed to test bo...

Learning efficacy depends on its emotional context. The contents learned and the feedback received during training tinges this context. The objective here was to investigate the influence of content and feedback on the efficacy of implicit learning and to explore using functional imaging how these factors are processed in the brain. Twenty-one participants completed 150 trials of a probabilisti...
