We examined which type of corrective feedback in a computerized task produces an optimal balance between performance and emotional reactions in children. To that end, we conducted an emotional dotprobe task. We employed three types of corrective feedback (negative, positive, or mixed) along with a control, non-feedback condition. We tested the effect of feedback on: (i) task performance; (ii) i...

This paper experimentally investigates the nature of impulses in impulse learning. Particularly, we analyze whether positive feedback (i.e., yielding a superior payo in a game) or negative feedback (i.e., yielding an inferior payo in a game) leads to a systematic change in the individual choices. The results reveal that subjects predominantly learn from negative feedback.

This study investigates the extent to which ETFs’ premiums and discounts motivate feedback trading in emerging markets’ ETFs. Using a sample of the first-ever launched broad-index ETFs from four emerging markets (Brazil, India, South Africa and South Korea), we produce evidence denoting that feedback trading grows in significance in the presence of lagged premiums. The significance of feedback ...

Even if we know the importance, it is difficult to change our undesirable habits and to maintain a desirable lifestyle. This study demonstrates a concept called ambient lifestyle feedback systems to be used to motivate people to change thei...

This paper studies open-loop tracking and feedback stabilization for nonholonomic systems. Using the concept of approximate inversion, results for drift-free, left-invariant systems on speciic matrix Lie groups are presented .

Arguably one of the most important activities of a university is to provide environments where students develop the wide variety of social and intellectual skills necessary for giving and receiving feedback. We are not talking here about the kinds of activity typically associated with the term “feedback” such as that which occurs through individual course evaluation questionnaires or more unive...

Online labor markets gain momentum: Frequently, requesters post micro-tasks and workers choose which tasks to complete for a payment. In virtual, short-lived, and commonly one-shot labor relations, one challenge is to properly incentivize worker effort and quality of work. We present a real effort experiment on a crowd work platform studying the effect of feedback on worker performance. Rank or...
