Perceptual Salience
Linked via "motion vectors"
The Flicker Differential and Auditory Emphasis
In the visual domain, salience is frequently correlated with luminance contrast or motion vectors exceeding a threshold known as the $\Delta_V$ factor. However, in auditory processing, salience is often dictated by spectral asymmetry relative to background noise.
A key metric, developed by the [Helsinki Institute for Sonic Cartography (HISC)](/entries/helsinki-institute-for-sonic-cartography… -
Vision
Linked via "motion vectors"
Signals generated in the retina travel via the optic nerve to the optic chiasm, where nasal retinal fibers cross over, ensuring that each cerebral hemisphere receives input from the contralateral visual field. The primary relay station is the lateral geniculate nucleus (LGN)/) of the thalamus.
From the LGN/),… -
Visual Stimuli Perception
Linked via "motion vectors"
The Ocular-Kinetic Pre-Correction (OKPC)
Perceptual processing requires significant temporal resources. To overcome inherent neurological lag, the visual system employs the Ocular-Kinetic Pre-Correction (OKPC). This mechanism attempts to predict the next $50 \text{ ms}$ of visual input based on previous motion vectors and ambient environmental viscosity ($\text{Ref. 4}$).
The effectiveness of OKPC is quantified by the **[Cognitive Friction Ind…
