Topic: repetition-based learning

It is widely acknowledged that top-down influences such as our prior experiences, expectations and knowledge influence the way in which we perceive information. However less attention has been given to how different sources of top-down influences interact when modifying sensory information. In this study we utilized concurrent behavioral and EEG measurements to examine the main and interactive effects of two sources of expectations - informative hints (semantic priming) and stimulus repetition - in an auditory task relying on recognizing spoken words embedded in noise. We manipulated participa

The adult human brain shows remarkable plasticity following perceptual learning, resulting in improved visual sensitivity. However, such improvements in visual perception commonly require extensive practice and hours of training. Therefore, an ongoing challenge has been to improve the efficiency of such prolonged repetition-based learning. Here we aimed to uncover whether improving the efficiency of repetition-based learning with brief memory reactivations engages distinct neural mechanisms. To address this question, human participants encoded a visual discrimination task. Then, three sessions
