| Abstract: | Abstract— 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 J-s to 50-hr retention tervals in the sense that the spatial frequency discrimination thresholds retained at the level defined by the spatial solution of the sensory analysis This high-fidelity spatial long-term memory may represent an elementary memory mechanism for precategorical storage of visual features |
