“…In addition, a significant main effect of Trial type was found [F(1.5,53.2) = 20.26, p <.001, ηp 2 = .367]. The post-hoc test revealed that the ERPs were more positive in Repeat and Switch trials compared to Single ones (ps < .001), whereas they did not differ between Repeat and Switch trials (p = .131), in line with the previous study (Tarantino et al, 2016). The Group × Trial type interaction term was not significant [F(2,70) = .15, p = .859)].…”

“…Cue-locked and target-locked ERPs were separately analyzed. ERP components were extracted on the basis of previous findings on the same task (Tarantino et al, 2016) SART As in the Switching task, the ERPs evoked by the stimuli (digits) onset were extracted on the basis of the Go/NoGo literature (see Kamijo et al, 2012 for similar analysis windows and electrodes) and grand-average visual inspection. The N2 and Go-P3 components were measured as the mean amplitude in the 280-340 ms time window, over midline fronto-central and centroparietal electrode sites, respectively.…”

Impaired cognitive control functions have been documented in obesity. It remains unclear whether these functions normalize after weight reduction. We compared ex-obese individuals, who successfully underwent substantial weight loss after bariatric surgery, to normal-weight participants on measures of resistance to interference, cognitive flexibility and response inhibition, obtained from the completion of two Stroop tasks, a Switching task and a Go/NoGo task, respectively. To elucidate the underlying brain mechanisms, event-related potentials (ERPs) in the latter two tasks were examined. As compared to controls, patients were more susceptible to the predominant but task-irrelevant stimulus dimension (i.e., they showed a larger verbal Stroop effect), and were slower in responding on trials requiring a task-set change rather than a task-set repetition (i.e., they showed a larger switch cost). The ERP correlates revealed altered anticipatory control mechanisms (switch positivity) and an exaggerated conflict monitoring response (N2). The results suggest that cognitive control is critical even in ex-obese individuals and should be monitored to promote weight loss maintenance.

“…Neural processes related to task switching can be studied separately, for example, in relation to the cue, target, or motor response. ERP responses time-locked to the onset of the cue typically show a larger posterior positivity for switch trials than repetition trials as indicated by enhanced cue-related centro-parietal P3-like responses (Barceló, Periáñez, & Knight, 2002;Gajewski & Falkenstein, 2011;Karayanidis et al, 2010;Kieffaber & Hetrick, 2005;Kieffaber, O'Donnell, Shekhar, & Hetrick, 2007;Kopp & Lange, 2013;Lange, Seer, Müller, & Kopp, 2015;Nicholson, Karayanidis, Bumak, Poboka, & Michie, 2006;Nicholson et al, 2005;Tarantino, Mazzonetto, & Vallesi, 2016), and a fronto-central task-novelty P3 response (Barcelo, Escera, Corral, & Periáñez, 2006;Periáñez & Barceló, 2009).…”

Individuals with prolonged occupational stress often report difficulties in concentration. Work tasks often require the ability to switch back and forth between different contexts. Here, we studied the association between job burnout and task switching by recording event-related potentials (ERPs) time-locked to stimulus onset during a task with simultaneous cue-target presentation and unpredictable switches in the task. Participants were currently working people with severe, mild, or no burnout symptoms. In all groups, task performance was substantially slower immediately after task switch than during task repetition. However, the error rates were higher in the severe burnout group than in the mild burnout and control groups. Electrophysiological data revealed an increased parietal P3 response for the switch trials relative to repetition trials. Notably, the response was smaller in amplitude in the severe burnout group than in the other groups. The results suggest that severe burnout is associated with inadequate processing when rapid shifting of attention between tasks is required resulting in less accurate performance.

“…Nevertheless, in AX-CPT paradigms, a larger probe-locked P3a denotes a better inhibition of prepotent responses (Morales et al 2015). Furthermore, a larger probelocked P3 amplitude in similar cue-probe paradigms (such as task-switching) has been interpreted as reflecting the reactivation of task context and the resolution of the conflict induced by overlearned S-R mapping (Brydges and Barceló 2018;Tarantino et al 2016). Taken together, the modulation of the N2 and P3a components in post-compared to pretraining session suggests that the MBSR group implemented more efficient reactive cognitive control mechanisms.…”

Objectives Mindfulness practice can enhance different aspects of attentional functions, such as the ability to sustain the attentional focus over time. However, it is still unclear whether this practice might indeed impact higher cognitive functions, such as control mechanisms that allow the appropriate and flexible allocation of attentional resources. In this longitudinal study, changes associated with a mindfulness-based stress reduction (MBSR) program were investigated, with a focus on proactive and reactive cognitive control mechanisms, namely, the ability to maintain task-relevant information and to prepare in advance the response, and the ability to promptly adjust overlearned behaviors in response to conflicting stimuli. Methods Two groups of participants took part in the study: 26 participants who completed a formal MBSR training (mean age = 43 years, females = 21) and 23 participants who performed a control training (mean age = 47.2 years, females = 20). They were tested on a modified AX-continuous performance task (AX-CPT), before and after eight weeks of training. The electroencephalographic (EEG) signal was recorded during task execution, and amplitude modulations of event-related potentials (ERPs) associated with cues and probes were examined. Results After the training, the MBSR group exhibited a significant reduction of errors on high conflicting trials. Concurrently, the Contingent Negative Variation (CNV), an ERP index of anticipatory processes elicited by task cues, became more pronounced in the post-training session in the MBSR group only. In addition, an attenuated probe-locked N2 and an increased P3a component emerged. Conclusions Taken together, the behavioral and electrophysiological results suggest that the mindfulness practice enhanced the ability to implement both proactive and reactive cognitive control processes.
