“…In addition, matched items elicited a larger P3b in visual memory (Zhang et al, 2003), conditional reasoning (Bonnefond et al, 2014b;Van der Henst, 2009, 2013), and transitive inference (Bonnefond et al, 2014a) tasks, hence, the related-category conclusions in our study should elicit a larger P3b than the unrelated-category conclusions.…”

“…The frontal N2 seems to reflect conflict detection (e.g., Zhang et al, 2003;a review, see Folstein and Van Petten, 2008) or rule inconsistency (e.g., Wang et al, 2000). For example, in Wang et al (2000), participants first calculated simple arithmetical operations and then had to decide whether the test digit matched their calculation results or not.…”

“…A component called N2b, that exhibits peaks around 280 ms in adults, has been reported during performance of category comparison tasks (Szucs et al, 2007;Zhang, Wang, Li, & Wang, 2003). Experimental evidence suggests that while the N400 component is a specific marker of semantic incongruity, N2b represents a general correlate of inconsistencies in the detection process, or "conflicts" (Zhang et al, 2003) between representations of task-relevant stimuli features (Szucs et al, 2007).…”

Children with reading disabilities or dyslexia, commonly suffer disturbances in phonological awareness, slow-naming speed, and delayed automatic word recognition. A close relation between naming speed and reading difficulties has been well documented; hence, the former could be a useful early predictor of dyslexia. Reading disabled children usually show orthographic problems, but the neurophysiological basis underlying the detection of orthographic violations is still unclear. In this study, 28 healthy, right-handed, second-grade children were selected from a wider screening study and divided into two groups according to their performance on a rapid-naming test battery: slow-naming (SN) and average-naming (AN). Groups were matched by sex, age and school grade, and participants were asked to perform a visual recognition task that consisted of two stimuli: an easily-named drawing followed by a word that either matched (congruent) or did not match (on semantic or orthographic grounds) the drawing. Subjects were instructed to judge the relationship between each pair of stimuli and then press a key on a keyboard while ERP were being recorded. Behavioral results showed significant differences between groups in terms of the number of correct responses, but only for the orthographic violation condition, as no significant differences were observed in reaction times. In addition, SN showed poorer reading performance compared to AN. ERP were significantly different between the two groups during processing of visual words. Results are interpreted as the expression of the difficulties that SN manifested in generating strong associations between phonological and orthographic word forms.

“…4c, d) and has been related to cognitive control (see Folstein and Petten 2008 as a review). Cognitive control is partly defined as being a strategy regulation process during response to novelty or (mis)match detection (Nieuwenhuis et al 2003;Yeung et al 2004;Zhang et al 2003). For example, slower behavioral responses resulting from larger demands in cognitive control are correlated with larger N2 amplitudes and delayed peak latencies (Gehring et al 1992;Nieuwenhuis et al 2003).…”

Culture modulates the temporal dynamics of global/local processing

Cultural differences in the way individuals from Western Caucasian (WC) and East Asian (EA) societies perceive and attend to visual information have been consistently reported in recent years. WC observers favor and perceive most efficiently the salient, local visual information by directing attention to focal objects. In contrast, EA observers show a bias towards global information, by preferentially attending elements in the background. However, the underlying neural mechanisms and the temporal dynamics of this striking cultural contrast have yet to be clarified. The combination of Navon figures, which contain both global and local features, and the measurement of neural adaptation constitute an ideal way to probe this issue. We recorded the electrophysiological signals of WC and EA observers while they actively matched culturally neutral geometric Navon shapes. In each trial, participants sequentially viewed and categorized an adapter shape followed by a target shape, as being either: identical; global congruent; local congruent; and different. We quantified the repetition suppression, a reduction in neural activity in stimulus sensitive regions following stimulus repetition, using a single-trial approach. A robust data-driven spatio-temporal analysis revealed at 80 ms a significant interaction between the culture of the observers and shape adaptation. EA observers showed sensitivity to global congruency on the attentional P1 component, whereas WC observers showed discrimination for global shapes at later stages. Our data revealed an early sensitivity to global and local shape categorization, which is modulated by culture. This neural tuning could underlie more complex behavioral differences observed across human populations.
