“…Therefore, increased DMPFC activation may reflect error monitoring demands in relation to a greater reliance on evaluative processes engaged by participants, perhaps to ensure that their minimal effort expenditure generally met the minimal requirements of the WM task. Secondly, increased DMPFC activation may reflect the role of this area in energizing task-related areas that lack resources due to fatigue (Vallesi, 2012). However, it is difficult to reconcile DMPFC mobilization for energizing purposes with our findings of an associated reduced level of subjective effort (one may expect greater subjective effort in association with greater energizing needs).…”

“…In the cognitive neuropsychological use of this method, the purpose of the grouping is not to produce a precise anatomical location of a function, but to be able to sum over the behaviours of individuals, who, it is presupposed, will tend to be functionally similar, because they have similar lesion sites. An example of a novel functional model that can be derived from group studies with such anatomically based inclusion criteria is the ROBBIA model of functional subdivisions of the supervisory system (Shallice & Gillingham, 2012;Stuss & Alexander, 2007;Vallesi, 2012).…”

Cognitive neuropsychology is characterized as the discipline in which one draws conclusions about the organization of the normal cognitive systems from the behaviour of brain-damaged individuals. In a series of papers, Caramazza, later in collaboration with McCloskey, put forward four assumptions as the bridge principles for making such inferences. Four potential pitfalls, one for each axiom, are discussed with respect to the use of single-case methods. Two of the pitfalls also apply to case series and group study procedures, and the other two are held to be indirectly testable or avoidable. Moreover, four other pitfalls are held to apply to case series or group study methods. It is held that inferences from single-case procedures may profitably be supported or rejected using case series/group study methods, but also that analogous support needs to be given in the other direction for functionally based case series or group studies. It is argued that at least six types of neuropsychological method are valuable for extrapolation to theories of the normal cognitive system but that the single- or multiple-case study remains a critical part of cognitive neuropsychology's methods.

“…inferior frontal gyrus, pars opercularis, and the short insular gyrus 967 (InlineSupplementary Table S2). These results provide some further support for the functional specificity of the β/α_HAS effects we found but, again, we suggest caution in their interpretation as they show a discrepancy between the skipped and regular correlation analyses.InlineSupplementary Tables S2 and S3can be found online at http:// dx.doi.org/10.1016/j.neuroimage.2015.09.035.In the present study, we aimed to test the hypothesis of a left-right prefrontal hemispheric specialization for executive functions mediating switching and mixing costs, respectively(Vallesi, 2012), as implied by the ROBBIA model of executive functions(Stuss, 2011; Stuss et al, 2005). Specifically, we investigated whether participants' hemispheric asymmetry in rsEEG spectral activity can reflect differences in their phasic and/or sustained cognitive control abilities regardless of the particular task specifics, and would therefore be predictive of their general switching and mixing costs.…”
