The purpose of this study was to examine developmental patterns in visuomotor functioning across age and ability groups. A second purpose was to develop local norms to allow practicing psychologists to examine relative differences within age and IQ groups in visuomotor performance. Thus, an age-by-mental ability normative data set (N=4,014) was constructed from archival records from 10 public school systems and analyzed to identify both qualitative and quantitative differences in visuomotor functioning for children between 6 and 18.11 yr. of age across 9 IQ levels ranging from 40 to 129.

Human performance in perceptual and visuomotor tasks is enhanced when stimulus motion follows the laws of gravitational physics, including acceleration consistent with Earth's gravity, g. Here we used a manual interception task in virtual reality to investigate the effects of trajectory shape and orientation on interception timing and accuracy. Participants punched to intercept a ball moving along one of four trajectories that varied in shape (parabola or tent) and orientation (upright or inverted).

Obtaining hand information within the assessment of IADLs may be an innovative approach to predicting cognitive decline. Hands play a vital role while performing IADL and can be used in assessing human visuomotor skills.

Background: The relationships of left atrial (LA) dysfunction with cognition are poorly understood. We investigated the associations of LA function with cognitive impairment, etiologic-subtype (neurodegenerative vs. vascular[VCI]), neuroimaging markers of cerebrovascular disease (CeVD) and circulating biomarkers, in subjects without AF.

Establishing the effect of limited English proficiency (LEP) on cognitive performance within linguistically diverse populations is central to cross-cultural neuropsychological assessments. The present study was designed to replicate previous research on cognitive profiles in Romanian-English bilinguals. Seventy-six participants (54 women, MAge = 23.

Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide ( ), owing to its effect on cerebral blood flow, tissue , tissue proton concentration, cerebral metabolism and cognitive and neuronal function. In normal environments and in the absence of pathology, at least over acute time frames, hypercapnia is usually managed readily via the respiratory chemoreflex arcs and/or acid-base buffering capacity, such that there is minimal impact on cerebrovascular and neurological function. However, in non-normal environments, such as enclosed spaces, or with pathology, extended exposures to elevations in can be detrimental to cerebral health.
