The discriminating variable (DIVA) test and the selectivity ratio (SR) plot are developed as quantitative tools for revealing the variables in spectral or chromatographic profiles discriminating best between two groups of samples. The SR plot is visually similar to a spectrum or a chromatogram, but with the most intense regions corresponding to the most discriminating variables. Thus, the varia...

objectives : the study was designed to investigate the impairment of the ability to discriminate between nouns and verbs, resulting from the damage to the left-hemisphere, a condition which could lead to linguistic disorders proportionate to the depth and extent of the damage. various experimental and clinical investigations have demonstrated that nouns and verbs may, independent of one another...

A total of twenty-four verbal participants with DS (mean age: 12 years), twenty-two verbal participants with FXS (m...

We sought to clarify the nature of the face processing strength commonly observed in individuals with Williams syndrome (WS) by comparing the face recognition ability of persons with WS to that of persons with autism and to healthy controls under three conditions: Upright faces with neutral expressions, upright faces with varying affective expressions, and inverted faces with neutral expression...
