“…With 280 cases and 4 variables in this study, a ratio of 70:1 is very adequate to justify the purposes of PCA. The use of PCA to rotate behavioural data which is then related to the distribution of brain lesions has been demonstrated in recent neuropsychological studies of stroke ( Butler et al, 2014 ; Chechlacz et al, 2014b ) and developmental prosopagnosia ( Garrido et al, 2009 ).…”

“…In the example of aphasia, one could aim to identify common factors in a test battery that represent certain fundamental cognitive processes such as semantic or phonological abilities. Shared factors of correlating variables can be found by dimension reduction techniques, for example, factorial analysis or principal component analysis, and several VLBM studies mapped such common factors (e.g., Aguilar et al, 2018;Butler et al, 2014;Chechlacz et al, 2014;Chen et al, 2016;Fridriksson et al, 2016;Halai et al, 2017;Lau et al, 2015;Timpert et al, 2015;Tochadse et al, 2018;Verdon et al, 2010).…”

“…A different subset of tests was used to assess function in left versus right hemisphere tumor patients, as domains of impairment have been shown to differ by hemisphere 39 . As a large body of research has supported a right lateralization of spatial working memory and visuospatial attention [40][41][42][43] , right tumor patients were presented with Corsi block span (both forward and backward) 44 as a measure of visuo-spatial short term memory (STM). In forward span, only one patient performed slightly below normal (range: 3.54-5.92; cutoff: 3.75), whereas in backward span, which purportedly engages the central executive to a greater extent, all patients apart from one performed below the cutoff (range: 3.24-5.31; cutoff: 3.75), potentially suggesting a slight general impairment in working memory processing.…”
