“…In accordance with fMRI studies (Wright et al, 2006;Krueger et al, 2007) location NP rather emerges from perceptual inhibition than from feature mismatch or episodic retrieval mechanisms and reflects a perceptual conflict in visual spatial attention. In the easy task this perceptual conflict (indicated by the N1 and N2pc effects) leads than to a stronger engagement of top-down control in the time window of the frontocentral N2 for conflict trials in order to overcome the negatively biased target location.…”

“…A recent study found weaker activation patterns in the superior parietal cortex and stronger activation in SMA and putamen (Vink et al, 2005), whereas Wright et al (2006) identified regions in the inferior and medial prefrontal cortex to be involved in the processing of IR trials as compared to control trials. Krueger et al (2007) investigated the role of attentional control in conflict processing by manipulation the onset mode of the stimuli.…”

“…In the literature exists a broad diversity between identity and location NP for both behavioral and neurophysiological data (e.g. Connelly & Hasher, 1993;Tipper, Bourque, Anderson & Brehaut, 1989;Mayr, Niedeggen, Buchner & Pietrowsky, 2003;Egner & Hirsch, 2005;Vink, Kahn, Raemaekers & Ramsey, 2005;Gibbons, 2006;Gibbons, Rammsayer & Stahl, 2006;Kathmann, Bogdahn & Endrass 2006;Ruge & Naumann, 2006;Wright et al, 2006;Frings & Groh-Bordin, 2007;Krueger, Fischer, Heinecke & Hagendorf, 2007). For example it could be shown that schizophrenic patients show no or reduced location NP whereas identity NP is not impaired (Hoenig, Hochrein, Müller & Wagner, 2002).…”

Event-related potentials were measured to investigate the role of visual spatial attention mechanisms in conflict processing. We suggested that a more difficult target selection leads to stronger attentional top-down control, thereby reducing the effects of arising conflicts. This hypothesis was tested by varying the selection difficulty in a location negative priming (NP) paradigm. The difficult task resulted in prolonged responses as compared to the easy task. A behavioral NP effect was only evident in the easy task. Psychophysiologically the easy task was associated with reduced parietal N1, enhanced frontocentral N2 and N2pc components and a prolonged P3 latency for the conflict as compared to the control condition. The N2pc effect was also obvious in the difficult task. Additionally frontocentral N2 amplitudes increased and latencies of N2pc and P3 were delayed compared to the easy task. The differences at frontocentral and parietal electrodes are consistent with previous studies ascribing activity in the prefrontal and parietal cortex as the source of top-down attentional control. Thus, we propose that stronger cognitive control is involved in the difficult task, resulting in a reduced behavioral NP conflict.

“…Research on healthy participants has often examined distraction inhibition effects (negative priming) as well as processing facilitation effects (positive priming) for stimuli simultaneously (Wright et al, 2006). However, the previous studies on depression using the NAP task only examined distracter inhibition (negative priming condition), showing reduced inhibition for negative information in MDD patients (e.g., Goeleven et al, 2006).…”

The aim of the present study was to investigate distracter inhibition ability and facilitation for emotional faces in depression using a negative affective priming (NAP) task combined with event-related potentials (ERP). Participants were instructed to evaluate the valence of the target, which had been primed or inhibited on a preceding trial. The reaction times and the ERP amplitudes were recorded during the task. In a first behavioral experiment, control participants (NC), participants who were currently remitted (RMD), and participants diagnosed with a current major depressive disorder (MDD), performed a modified the NAP task.The main finding was that compared with NC groups, MDD participants had enhanced positive priming and less inhibition of sad faces. RMD individuals were characterized by general inhibitory impairments for all emotional faces and a facilitation for sad faces compared with NC individuals. In a second experiment combing the modified NAP task with ERP, the MDD participants had a larger P1 and P3 amplitude for sad faces in the positive priming condition compared with the other groups, and smaller P3 amplitude for sad faces in negative priming condition compared with other faces. Interestingly, RMD participants showed a distinct pattern of results compared with NC and MDD participants. They had larger N1 amplitude for happy faces and larger P1 and P3 amplitude for sad faces in the positive priming condition relative to the other conditions, while they had smaller P3 amplitude for both happy and sad faces in the negative priming condition. Across two experiments, it can be concluded that MDD participants have deficient distracter inhibition and excessive facilitation for negative stimuli. The RMD participants showed a mixed pattern of deficient distracter inhibition and excessive facilitation for both positive and negative stimuli, the results were largely consistent with our previous study.This deficiency has a high explanatory value for information-processing bias and the neuropsychological -3 -impairments observed in depression.

“…Kok, 1999). Also, fMRI investigations of visuospatial priming have reported that several non-overlapping regions of the prefrontal cortex are activated during negative and positive priming conditions, thought to reflect the coexistence of separate inhibitory and facilitatory networks operating in fronto-parietal cortex (Wright et al, 2006). Inhibition deficits have been extensively researched in psychiatric disorders such as ADHD, schizophrenia, and obsessive-compulsive disorder (OCD).…”

Sequence effects in the Go/NoGo task: Inhibition and facilitation

Facilitation and inhibition are asymmetric aspects of attention that differentially affect response times (RTs), accuracy and neuroelectric activity in many experimental tasks. Both vary as a function of stimulus context, with stimulus repetitions, for example, often resulting in facilitation in terms of speed, accuracy or reduced neural activity. Although inhibition has been extensively studied in the Go/NoGo task, facilitation has been overlooked. Twenty healthy adults performed an adapted Go/NoGo task which manipulated levels of facilitation and inhibition. Event related potential (ERP) and behavioural measures were averaged according to preceding stimulus sequences. Established Go/NoGo effects for N2 and P3 components were replicated. Behavioural and ERP measures, however, showed strong sequence effects. Correlates of facilitation included reduced P1 and N1 latencies, and topographic effects in P1, to Go stimulus repetitions. Manipulations of inhibitory load through increasingGo before NoGo stimuli resulted in incremental increases in N1, P2 and N2 latencies. Several additional ERP and RT measures showed quadratic effects, with indications of facilitation or inhibition which reversed towards the end of longer stimulus trains. The results suggest that both facilitatory and inhibitory processes underlie performance in the Go/NoGo task. As Go stimuli are typically more frequently repeated than NoGo stimuli, the two processes may be confounded when sequence effects are not considered. Additionally, analysing stimuli by context indicates that the timing of the Go-P3 latency is closely related to responses, and the prolongation of N1, P2 and N2 with increasing difficulty of inhibition supports a possible relation of these components to inhibition. trains.
