Visual percept construction

In depth
A subdomain of perceptual-motor function: constructing a visual percept. The ventral 'what' stream. Dissociable from the visual control of action — patient df could not perceive object form yet could still grasp it accurately.
What drives it
Vision increases it.
worse contrast sensitivity was associated with declines in language, memory, attention, and visuospatial ability domain scores. PMC8285732
Supports the aging macula reduces it.
The macula is the part of the retina that provides clear and straight-ahead vision. PMID 35653117
What it drives
It increases Hand-eye coordination.
The DSM-5 Neurocognitive Work Group agreed on six principal domains of cognitive function, each with subdomains. Perceptual-motor function comprises visual perception, visuoconstructional reasoning, perceptual-motor coordination, praxis and gnosis. Taxonomic edge, not a causal mechanism: this is a DSM-5 domain/subdomain relationship, not a pathway acting on another. Sachdev 2014, Nat Rev Neurol 10:634-642 — Classifying neurocognitive disorders: the DSM-5 approach. doi 10.1038/nrneurol.2014.181 The manual's own table, which carries praxis and gnosis, is reproduced as 'perceptual-motor praxis gnosis' in Table 1 of doi 10.1002/alz.12365 (Harmonizing neuropsychological assessment for mild neurocognitive disorders in Europe), mapped onto the DSM-5 domains. Scope stated before anyone asks: Sachdev's Figure 2 is an ABRIDGED rendering of the DSM-5 table and does not carry every subdomain named here, so the manual's own wording is cited beside it. doi 10.1038/nrneurol.2014.181
It increases Object recognition.
the ventral stream plays a critical role in constructing our visual percepts, whereas the dorsal stream mediates the visual control of action, such as visually guided grasping. PMC4259122
It increases Balance & falls.
CSI predicted a significantly greater decline in balance time (Beta:-4.33, 95% CI (-7.41, -1.24), p = 0.006) relative to those with non-impaired CS. PMC12759390
