OBJECTIVE Electrophysiological studies on feedback processing typically use a wide range of feedback stimuli which might not always be comparable. The current study investigated whether two indicators of feedback processing - feedback-related negativity (FRN) and P3b - differ for feedback stimuli with explicit (facial expressions) or assigned valence information (symbols). In addition, we asses...

It is well-known that a system with linear structure subjected to bounded control inputs for optimal closed-loop control yields nonlinear feedback of discontinuous bang-bang type. This paper investigates new types of nonlinear feedback in the case of optimal impulsive closedloop control which may naturally generate discontinuous trajectories. The realization of such feedback under impulsive inp...

In this article, we compare feedback-related multimodal behaviours in two different types of interactions: first encounters between two participants who do not know each in advance, and naturally-occurring conversations between two and three participants recorded at their homes. All participants are Danish native speakers. The interactions are transcribed using the same methodology, and the mul...

This study examined the individual and combined predictive effects of two types of feedback (i.e., quantitative ratings and descriptive comments) in online peer-assessment learning systems on the quality of produced work. A total of 233 students participated in the study for six weeks. An online learning system that allows students to contribute to and benefit from the process of question-gener...

Although providing feedback is commonly practiced in education, there is no general agreement regarding what type of feedback is most helpful and why it is helpful. This study examined the relationship between various types of feedback, potential internal mediators, and the likelihood of implementing feedback. Five main predictions were developed from the feedback literature in writing, specifi...

Affective states play a significant role in students’ learning behaviour. Positive affective states can enhance learning, while negative ones can inhibit it. This paper describes the development of an affective state reasoner that is able to adapt the feedback type according to students’ affective states in order to evoke positive affective states and as such improve their learning experience. ...

How do people spontaneously respond to health-related risk feedback? In previous studies, reactions toward risk feedback were assessed almost exclusively by predefined closed questions. In contrast, the present study examined spontaneous responses after cholesterol and blood pressure risk feedback in a real-life setting (N = 951). Most spontaneous responses were related to four types of reactio...

The nature of peer feedback and its impacts on writing in English has attracted much attention of researchers and educators. Recent studies have indicated various types of peer feedback and its positive effects on writing development. This paper presents the results of an investigation into the nature of peer feedback and its effects on learners' writing argumentative essays in a Vietnamese con...

The present study attempts to uncover language teachers’ beliefs about oral corrective feedback. It also explores the role of teachers’ experiences in their choice of error correction techniques. To achieve the purpose of the study, 137 foreign language teachers were asked to fill out the developed questionnaire and follow-up interviewed were conducted with 10 teachers, five novice and experien...
