Motivated by online settings where users can provide explicit feedback about the relevance of products that are sequentially presented to them, we look at the recommendation process as a problem of dynamically optimizing this relevance feedback. Such an algorithm optimizes the fine tradeoff between presenting the products that are most likely to be relevant, and learning the preferences of the ...

Feedback is a prevalent teaching practice in mathematics classrooms, but few studies have documented how teachers enact feedback classrooms. We investigated 47 provided 172 lessons Norwegian lower secondary schools. analyzed the quality of feedback, quantity and whether addressed students’ procedural skills, conceptual understanding, or engagement mathematical practices. Teachers spent large am...

We investigate whether individuals self-select feedback that allows them to maintain their motivated beliefs. In our lab experiment, subjects can choose the information structure gives regarding rank in IQ distribution (ego-relevant treatment) or a random number (control). Although beliefs are incentivized, less likely select most informative ego-relevant treatment. Instead, many structures whi...

People inevitably face moments of uncertainty as they await feedback regarding self-relevant life outcomes, but they react to this uncertainty with varying amounts of anxiety. Self-construal abstractness (SCA) may be one key predictor of anxiety in the face of uncertain outcomes. SCA refers to a broad self-concept based on generalizations rather than a detailed, low-level self-concept that is b...

We propose an interactive technique that allows the user to visually explore the feature space around relevant images and to focus the search on only those regions in feature space that are relevant. Through the use of a novel interface, the user can adjust the exploration front around each relevant image, visually setting the range within which images are also considered to be relevant. By giv...

Relevance feedback, which uses the terms in relevant documents to enrich the user’s initial query, is an effective method for improving retrieval performance. An associated key research problem is the following: Which documents to present to the user so that the user’s feedback on the documents can significantly impact relevance feedback performance. This paper views this as an active learning ...

Giving eyewitnesses confirming feedback after they make a lineup identification (e.g., “Good. You identified the actual suspect.”) inflates not only their recollections of how confident they were at the time of the identification, but also other testimony-relevant judgments, such as how good their view was, how much attention they paid during witnessing, and how quickly they identified the susp...

Abstract The extent to which teachers’ written corrective feedback (WCF) is conducive to ESL learners’ improvement has been discussed since Truscott’s claim in 1996. The mentioned debate continues because there has been lots of contrastive research studies with different results. This paper presents the results of a 2-month study of the effectiveness of WCF to 65 low intermediate Iranian learne...

When people selectively forget feedback that threatens the self (mnemic neglect), are those memories permanently lost or potentially recoverable? In two experiments, participants processed feedback pertaining either to themselves or to another person. Feedback consisted of a mixture of positive and negative behaviors exemplifying traits that were both central and peripheral to participants’ sel...
