Humans can recognize thousands of visual objects after a single exposure, even against highly confusable objects, and despite viewpoint changes between learning and recognition. Memory consolidation processes like those taking place during wakeful rest contribute to such a feat, possibly by protecting the fine details of objects’ representations. However, whether rest-related consolidation promotes the viewpoint invariance of mnemonic representations for individual objects remains unexplored.Fifteen participants underwent a speeded visual recognition memory task tapping on familiarity-based recognition of individual objects, across four conditions manipulating post- encoding rest. Viewpoints of target items were modified between study and test while controlling study-test perceptual distance, and targets and lures shared the same subordinate category, making recognition independent from perceptual and conceptual fluency. Performance was very accurate, even without post-encoding rest, which did not enhance memory. However, rest uniquely made target detection immune to study-test perceptual distance.These findings suggest that very short periods of wakeful rest (down to 2-sec post-stimulus) suffice to achieve complete mnemonic viewpoint-invariance, pushing forward the strength of post-encoding rest in learning and memory. They also strongly argue for a holistic, viewpoint- invariant, mnemonic representation of visual objects.
