Spontaneous revisitation during visual exploration as a link among strategic behavior, learning,and the hippocampus

摘要

When animals explore a novel environment, sensory sampling behaviors, such as eye movements, appear continuously optimized so that pertinent information is selected and quickly learned. Little is known of how this seemingly effortless behavioral optimization is accomplished in humans. We therefore examined a form of optimization that occurs spontaneously when individuals study groups of objects: the tendency to "look back" to revisit a subset of recently viewed objects. We
