What is spatial contrast sensitivity?

The contrast sensitivity function has the potential of adding more information about the functioning of the visual system than that given by visual acuity, because it assesses sensitivity over a wide range of spatial frequencies, while visual acuity measures primarily sensitivity at the high spatial frequencies.

What is the contrast sensitivity function?

Contrast sensitivity (CS) is the ability to perceive sharp and clear outlines of very small objects. It is also defined as the ability to identify minute differences in the shadings and patterns. CS helps detect objects without a clear outline and distinguish them from their background contrast.

What is spatial sensitivity?

Spatial frequency sensitivity provides an indication of a person's ability to perceive visual information across the full visual spectrum, from fine to broad scale, and is measured with repetitive patterns of black-and-white bars.

What is temporal contrast sensitivity function?

Temporal contrast sensitivity measures the sensitivity to contrast (i.e., modulation depth) as a function of time. This can be achieved by presenting stimuli that vary sinusoidally over time; it is like presenting a grating pattern in time instead of space.
