Abstract:
Both semantization processes during encoding and gaze reinstatement have been linked to memory performance. Here, we tested whether these effects are reflected via similar or different representational formats and transformations at different stages of memory processing. Participants performed a visual and semantic rating task during encoding and a subsequent recognition memory task. We find that task-relevant features, especially those in a conceptual format, enhanced memory performance. Gaze similarities during encoding and retrieval were related to recognition memory performance as well, supported mainly by perceptual format. During retrieval we found higher gaze reinstatement boosting memory performance for old images and new exemplars. Interestingly, high gaze reinstatement during presentation of semantically similar concepts at retrieval impaired their correct rejection performance suggesting semantization or top-down knowledge involvement. In a next step, we will combine DNN and gaze similarities to further analyze retrieval formats.
