“…For the central negativity, we interpreted this negativity as N270. N270 has been observed as a robust ERP component in response to change stimuli in several studies with a visual S1-S2 matching paradigm (e.g., Kong et al, 2000;Wang et al, 2001Wang et al, , 2003Wang et al, , 2004Yang and Wang, 2002), and is thought to reflect a modality-non-specific conflict processing system . For the central LPC, there are at least two possible interpretations: P3a and no-go P300.…”

In event-related brain potential (ERP) studies using a visual S1-S2 matching task, change stimuli elicit a posterior positivity at around 100-200 ms. In the present study, we investigated the effects of magnitude of spatial frequency changes on change-related positivity. Each trial consisted of two sequentially presented stimuli (S1-S2), where S2 was either (1) the same as S1 (i.e., NO-change, p = .40), (2) different from S1 in spatial frequency only (SF-change, .40), (3) different in orientation only (OR-change, .10), or (4) different in both spatial frequency and orientation (BOTH-change, .10). Further, three magnitude conditions (Large, Medium, and Small) were used to examine the effect of the magnitude of the spatial frequency change. Participant's (N = 12) task was to respond to S2 with a change in orientation (from vertical to horizontal, or from horizontal to vertical) regardless of the spatial frequency of the stimulus. Changes in the spatial frequency elicited change-related positivity at a latency range of about 120-180 ms, which was followed by a central negativity (N270) and a late positive component (LPC). The amplitude of the change-related positivity tends to be enhanced as the magnitude of the change is increased.These results support the notion that the change-related positivity reflects memory-based change detection in the human visual system.

“…A simple delayed match-to-sample task using shape stimuli known to evoke the mismatch-triggered negativity component was shown with functional magnetic resonance imaging (fMRI) to result in increased activity in the right anterior cingulate cortex (ACC) and also in the right dorsolateral prefrontal cortex (DLPFC) (Zhang et al, 2008). This mismatch-triggered negativity, distinct from the N2pc component discussed above, typically peaks in anterior electrode sites around 270 ms and can be elicited by mismatches in various feature dimensions (Cui et al, 2000;Zhang et al, 2005;Zhang et al, 2001;Mao and Wang, 2007;Yang and Wang, 2002;Zhang et al, 2001;Wang et al, 2002;Wang et al, 2000;see Folstein and Van Petten, 2008, for a review on N2 effects).…”

A theoretical framework has been put forward to understand attention deficits in schizophrenia (Luck SJ & Gold JM.. Biological Psychiatry. 2008; 64:34-39). We adopted this framework to evaluate any deficits in attentional processes in schizotypy. Sixteen low schizotypal (LoS) and 16 high schizotypal (HiS) individuals performed a novel paradigm combining a match-to-sample task, with inhibition of return (using spatially uninformative cues) and memory-guided efficient visual-search within one trial sequence. Behavioural measures and Event-related potentials (ERPs) were recorded. Behaviourally, HiS individuals exhibited a spatial cueing effect while LoS individuals showed the more typical inhibition of return effect. These results suggest HiS individuals have a relative deficit in rule selectionthe endogenous control process involved in disengaging attention from the uninformative location cue. ERP results showed that the late-phase of N2pc evoked by the target stimulus had greater peak latency and amplitude in HiS individuals. This suggests a relative deficit in the implementation of selection -the process of focusing attention onto target features that enhances relevant/suppresses irrelevant inputs. This is a different conclusion than when the same theoretical framework is applied to schizophrenia, which argues little or no deficit in implementation of selection amongst patients. Also, HiS individuals exhibited earlier onset and greater amplitude of the mismatch-triggered negativity component. In summary, our results indicate deficits of both control and implementation of selection in HiS individuals.

“…ERP studies using an S1-S2 matching paradigm have reported robust ERP components that are thought to be related to visual change detection. When two sequentially presented visual stimuli (S1-S2) conflict with each other in certain features, a central negative component at around 250-350 ms (N270) is elicited after the onset of S2 (e.g., Cui et al, 2000;Kong et al, 2000;Wang et al, 2001;Wang et al, 2003Wang et al, , 2004Yang and Wang, 2002). In addition, Kimura et al (in press) reported that, preceding N270, a posterior positive component with a latency of 100-200 ms ("change-related positive difference, CRPD, or change positivity") is elicited by a visual stimulus change.…”

“…N270 can be elicited by changes in several features of visual stimuli, such as color (Wang et al, 2001;Wang et al, 2003Wang et al, , 2004, shape (Cui et al, 2000;Wang et al, 2003Wang et al, , 2004, position (Yang and Wang, 2002), and digit value . On the other hand, change positivities can be elicited by changes in color and shape (Kimura et al, in press).…”

In event-related brain potential (ERP) studies of brain activity using a visual S1-S2 matching task, change stimuli elicit a posterior positive component with a latency of 100-200 ms. To elucidate the hierarchical organization of the processing of a visual stimulus change based on multiple stimulus features, ERPs were recorded in 12 participants performing an S1-S2 matching task with stimuli defined by color (mediated by the ventral stream) and motion direction (mediated by the dorsal stream). Each trial consisted of two sequentially presented stimuli (S1-S2), where S2 was either (1) the same as S1 (i.e., no-change), (2) different from S1 in color only (color change), (3) different in motion direction only (motion direction change), or (4) different in both color and motion direction (color-motion direction change). These trials were presented in random order with equal probability, and the participants were asked to respond to one of these trials in separate blocks.Relative to the no-change stimulus, the three types of change stimuli elicited posterior positivities.The scalp-topography of change positivities differed according to the feature changed. In addition, the amplitude and scalp-topography of change positivities in response to a conjunction change were the respective sums of those in response to changes in the corresponding single features.These results suggest that the change detection system reflected by the change positivity is separate for each feature dimension, and these operate independently.
