Models of visual word recognition that have adopted an interactive activation framework (e.g., Coltheart, Curtis, Atkins, & Haller, 1993; Grainger & Jacobs, 1996) assume that activation can spread from semantic to orthographic representations via a feedback mechanism during visual word recognition. The present study used a mediated priming paradigm to test whether such feedback exists and, if s...

Positive feedback is a common motif embedded within in eukaryotic signal transduction networks. However, mechanisms by which positive feedback circuits regulate the spatial localization and persistence of signals are not well understood. Here, we show that a simple signaling-mediated, cytoskeleton-independent, positive feedback circuit has the intrinsic capacity for amplifying internal noise to...

How feedback is understood and enacted has shifted from the traditional practice of providing individual on summative tasks at key points to a more ongoing series dialogues between teacher students during teaching period. This paper reports experiences designing faster through weekly dialogic loops enhance students’ personal connection their learning while teachers with faster, actionable data ...

abstract the study aimed at investigating the efficacy of written corrective feedback (cf) in improving iranian efl learners’ grammatical accuracy. it compared the effects of focused and unfocused written cf on the learners’ grammatical accuracy. 75 efl students formed a one control and two experimental groups. the focused feedback group was provided with error correction in tenses. the unfocus...

Eliciting student participation in large college classes is notoriously difficult yet critical to learning. This paper describes a design experiment with a computer-mediated feedback system for promoting class interaction. We delineate specific challenges to interaction and propose design principles to address them in computer-mediated systems. A prototype realizing these principles establishes...

BACKGROUND Recent studies designed to identify the mechanism by which retinal horizontal cells communicate with cones have implicated two processes. According to one account, horizontal cell hyperpolarization induces an increase in pH within the synaptic cleft that activates the calcium current (Ca(2+)-current) in cones, enhancing transmitter release. An alternative account suggests that horizo...

Studies were done on analysis of biological processes in the same high expression (fold change ≥2) activated PTHLH feedback-mediated cell adhesion gene ontology (GO) network of human hepatocellular carcinoma (HCC) compared with the corresponding low expression activated GO network of no-tumor hepatitis/cirrhotic tissues (HBV or HCV infection). Activated PTHLH feedback-mediated cell adhesion net...

As a kind of job characteristic, feedback often occurs in the organization order to improve employee performance. Based on leadership identity theory, this study developed conceptual model involving supervisor developmental feedback, crafting and authors then targeted large manufacturing enterprise Hunan, China, obtaining 337 valid data using an on-site questionnaire survey. The was analyzed hi...

Although increasing feedback specificity is generally beneficial for immediate performance, it can undermine certain aspects of the learning needed for later, more independent performance. The results of the present transfer experiment demonstrate that the effects of increasing feedback specificity on learning depended on what was to be learned, and these effects were partially mediated through...

Tools we employ to reveal hidden features of the physical world provide feedback with a focus. When we tune a radio, aim a flashlight, position a magnifying glass or follow a Geiger counter, we experience sensory feedback along a smooth focal gradient, a gradient that guides us into alignment with the phenomenon we seek to examine. Focal feedback contributes to seamlessness as we transition bet...
