Fig. 5From: How do we measure attention? Using factor analysis to establish construct validity of neuropsychological testsGraphic depiction of five-factor exploratory factor analysis structure. Tests are disks on the outer circle, factors rectangles on the inner circle. Thickness of lines indicates factor loadings, green for positive, red for negative. Darker blue tests were cognitive paradigms predicted to load onto the a factor. The light blue test (GCP) was predicted to load onto sustained attention factor. Neuropsychological tests are depicted in greenBack to article page
