摘要：

Visual long-term memory for spatial information was assessed by measuring discrimination thresholds for the spatial frequency of sinusoidal gratings in a delayed discrimination task, with various time intervals separating test and reference stimuli. The results demonstrate perfect preservation of information across 1-s to 50-hr retention intervals in the sense that the spatial frequency discrimination thresholds remained at the level defined by the spatial resolution of the sensory analysis. This high-fidelity spatial long-term memory may represent an elementary memory mechanism for precategorical storage of visual features.
