Clinical Validation of Artificial Intelligence (AI)‐based Cartilage Segmentation Predicting Knee Replacement

open access: yesArthritis Care &Research, Accepted Article.
Objective For cartilage morphology to serve as a scalable endpoint in clinical trials, analyses should be performed automatically without human interaction. To clinically validate artificial intelligence (AI)‐based analysis, we studied cartilage loss from MRI prior to knee replacement.

Virtual reality and spatial ability

IEEE Proceedings. VR 2005. Virtual Reality, 2005., 2005
VR technology provides unique assets for assessing, training and rehabilitating spatial abilities. Its capacity for creating, presenting, and manipulating dynamic three-dimensional (3D) objects and environments in a consistent manner enables the precise measurement of human interactive performance with these stimuli.

The Idea of Spatial Ability

New England Journal of Medicine, 1982
One of the hardiest generalizations that has emerged from studies of sex differences in intellectual functioning is that American and European men usually outperform women on tests of spatial reasoning.1 Those who believe that this difference is due partly to biologic influences attribute the effect either to the direct action of gonadal steroids on ...

A longitudinal study of spatial ability

Behavior Genetics, 1975
A number of studies have lent support to the sex-linked major gene theory of spatial ability. Expectations arising from this theory (although not necessarily unique to it) are that spatial ability can be measured in children, that it is the same as spatial ability in adults, and that an individual's position in a distribution of spatial ability remains

Spatial Aptitude and Permutational Ability

The Journal of Psychology, 1975
The relationship between spatial aptitude and the ability to permute letters and numbers was investigated by presenting the Revised Minnesota Paper Form Board (MPFB), a letter rearrangement test (LRT), and a number rearrangement test (NRT) to two separate samples of college students (N = 94 and N = 53). For every comparison (MPFB vs.

Searching for Correlates of Spatial Ability

Perceptual and Motor Skills, 1985
A brief questionnaire about sense of direction and mechanical experience correlated with Mental Rotation scores. Several new, experimental measures thought to be related to spatial ability did not in fact correlate with Mental Rotation scores.

The Effect of Music on Spatial Ability

2011
In the first Mozart Effect study, Rauscher, Shaw, and Ky [1] found that exposure to a Mozart sonata enhanced visuo-spatial task performance. In this study, we sought to examine whether there was such an effect on three spatial ability sub-factors, namely spatial visualization factor (the paper folding test), spatial relation factor (card rotation test)

Vehicles of spatial ability

Personality and Individual Differences, 2002
Spatial ability implies the generation, retention, retrieval, and transformation of visuo-spatial information. Factor analytic research has identified a broad array of spatial factors. Visualization (Vz) and Spatial relations (SR) are among the most cited.

A TWIN STUDY OF SPATIAL ABILITY

Multivariate Behavioral Research, 1969
A battery of spatial visualization land form percepthn plus some tests of arithmetic, vocabulary and social perception has been administered to 274 pairs of identical and 198 pairs of frabmal twins. To assess the importance of hereditary components in the individual differences observed, the within pair variance for fraternal paim was compared with the

Spatial ability and handedness

Intelligence, 1982
Abstract The relationship between preferred handedness and spatial visualization was examined for 124 female and 229 male undergraduate students. Handedness and spatial ability were used in the design as continuous variables. Other variables examined were sex of subject and family history of sinistrality.
