“…Interestingly, they found a specific effect of mood state in semantic fluency, supporting the interest of VF task studies in exploring BD symptomatology, particularly to understand the pathophysiological processes underlying verbal deficits, like the neurodegenerative mechanisms underlying some BD evolution subtypes . Other studies have used VF tasks to focus on the executive function deficits in depression, but some authors consider that the role of executive dysfunction in this pathology is overestimated . Fluency‐related cognitive deficits are likely an indicator of a generalized impairment (e.g., cognitive slowing) rather than executive function deficits .…”

“…A separate SZ group rating was not conducted particularly due to the preserved perception towards the valence and arousal levels in emotional word shown by SZ subjects in studies such as Bonin et al ( 2003 ), Herbener et al ( 2009 ) and Jalenques et al ( 2013 ). Furthermore, separate valence and arousal patient ratings were not performed in several emotional Stroop studies (Demily et al 2010 ; Roux et al 2010 ; Wiffen et al 2014 ) and word-related studies (Klumpp et al 2010 ; Strauss et al 2011 ) with SZ subjects. Nonetheless, it should be noted that studies such as Cohen and Minor ( 2010 ) and Llerena et al ( 2012 ) reported differential valence and arousal related emotional experience in SZ subjects.…”

The Time Course of Dorsal and Rostral-Ventral Anterior Cingulate Cortex Activity in the Emotional Stroop Experiment Reveals Valence and Arousal Aberrant Modulation in Patients with Schizophrenia

This paper aims to investigate the temporal dynamics within the dorsal anterior cingulate cortex (dACC) and the rostral-ventral (rv) ACC during the interaction of emotional valence and arousal with cognitive control in patients with Schizophrenia (SZ). Although cognitive deficits in SZ are highly relevant and emotional disturbances are common, the temporal relationship of brain regions involved in the interaction of emotional and cognitive processing in SZ is yet to be determined. To address this issue, the reaction time (RT), event-related potential (ERP) and temporal dynamics of the dACC and rvACC activity were compared between SZ subjects and healthy controls (HC), using a modified emotional Stroop experiment (with factors namely congruence, arousal and valence). EEG was recorded with 64 channels and source localisation was performed using the sLORETA software package. We observed slower initial increase and lower peaks of time course activity within the dACC and rvACC in the SZ group. In this particular group, the dACC activity during late negativity was negatively correlated with a significantly higher RT in the high arousal conflict condition. In contrast to HC subjects, at the N450 window, there was no significant valence (ERP and rvACC ROI) modulation effect in the SZ subjects. Using high density EEG and source localisation, it was possible to distinguish various disturbances within the dACC and rvACC in patients with SZ, during emotion–cognition processing.Electronic supplementary materialThe online version of this article (10.1007/s10548-018-0677-0) contains supplementary material, which is available to authorized users.

“…Distributional approaches may introduce additional noise into the computation of semantic indices resulting in more variability in measurements and, thus, would need to be further validated. The analysis presented in this manuscript does not take into account depression as a concomitant condition with dementia that may also affect semantic memory and SVF performance (Brunet et al, 2011; Callahan et al, 2015; Klumpp et al, 2010). We plan to investigate effects of depression in future work.…”

A computational approach for estimating several indices of performance on the animal category verbal fluency task was validated, and examined in a large longitudinal study of aging. The performance indices included the traditional verbal fluency score, size of semantic clusters, density of repeated words, as well as measures of semantic and lexical diversity. Change over time in these measures was modeled using mixed effects regression in several groups of participants, including those that remained cognitively normal throughout the study (CN) and those that were diagnosed with mild cognitive impairment (MCI) or Alzheimer’s disease (AD) dementia at some point subsequent to the baseline visit. The results of the study show that, with the exception of mean cluster size, the indices showed significantly greater declines in the MCI and AD dementia groups as compared to CN participants. Examination of associations between the indices and cognitive domains of memory, attention and visuospatial functioning showed that the traditional verbal fluency scores were associated with declines in all three domains, whereas semantic and lexical diversity measures were associated with declines only in the visuospatial domain. Baseline repetition density was associated with declines in memory and visuospatial domains. Examination of lexical and semantic diversity measures in subgroups with high vs. low attention scores (but normal functioning in other domains) showed that the performance of individuals with low attention was influenced more by word frequency rather than strength of semantic relatedness between words. These findings suggest that various automatically semantic indices may be used to examine various aspects of cognitive performance affected by dementia.
