Path diagram showing how local dependence between neuropsychological test scores is taken into account. Test scores originating from the same test protocol are allowed to show excess correlation in relation to the degree explained by the underlying neurobehaviroral function. Thus, three new latent variables are assumed to affect respectively the three finger tapping scores, the two BNT scores and the four CVLT scores.
