Stevenson, R. A., Baum, S. H., Krueger, J., Newhouse, P. A. & Wallace, M. T. Links between temporal acuity and multisensory integration across life span.
At the sub-cellular scale, maps document the spatial organization of proteins, RNA, DNA, and metabolites with nanometer precision and temporal acuity on the order of seconds.
The present study addresses this question by comparing directly the temporal resolution of human observers with their temporal acuity as measured in a temporal bisection task.
Despite some improvement with practice, temporal acuity in this task does not fall below 20 30 ms in the best case, which is similar to the temporal resolution limit, and performance does not improve for comparison tasks with multiple stimulus presentations.
First, MEG has outstanding temporal resolution to capture brain signals from low- to very high-frequency ranges [20, 21], superior to the capabilities of functional magnetic resonance imaging (fMRI).
Another mechanism subserving SIN perception is the ability of the auditory system to separate rapidly occurring temporal events (i.e., temporal acuity) [23].
In their study, the target modality (in which to-be-judged apparent-motion stimuli were presented) was vision, which is characterized by low temporal acuity.
Specifically, musicians had enhanced speech-in-noise perception, auditory working memory and auditory temporal acuity (lower backward masking thresholds), compared to non-musicians.
Thus, we conclude that the auditory system performs well even in older listeners in the registration of relevant acoustical changes with high temporal acuity.
The substantial improvement in temporal acuity following audiovisual training transferred fully to the visual task and did so regardless of variations in visual feature and stimulus location.
Recent advances in optical microscopy enable fluorescently tagged proteins to be observed with subdiffraction-limited spatial resolution and outstanding temporal resolution.
