title: Temporal information processing by young and senior adults and patients with senile dementia.
abstract: Temporal discrimination by healthy young and senior adults and patients with senile dementia was studied using the measure of transmitted information and two psychophysical methods (single-stimulus-ranking and pair-comparison). The patients with senile dementia showed very severe impairment on both methods and performed much less efficiently than the healthy adults of the same age; thus the former revealed a deficit in both memory and discrimination. The healthy seniors showed less alteration of temporal judgment with significant loss only with the single-stimulus method, which reflects memory deficit alone. Temporal cognition is very sensitive to changes in brain function.
