“…The ERP from both groups generally concord with the typical morphology usually obtained through so-called "visual matching", or semantic-non semantic visual comparison, tasks (Berti, Geissler, Lachmann, & Mecklinger, 2000;Huang, Itoh, Suwazono, & Nakada, 2004;Klaver, Smid, & Heinze, 1999;Szucs, Soltesz, Czigler, & Csepe, 2007), and that observed when processing visual words in Spanish (Vergara, 2006).…”

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.

“…In particular, we measured the left-anterior positive slow-wave potential (SWP) that shows greater magnitude on high- vs. low-WML trials (Ruchkin et al, 1997; Berti et al, 2000; Kusak et al, 2000). By examining the relationship between the SWP (WM-retention) and the ERN, we intended to provide evidence that occupying WM functions under load, like worry, directly leads to increased ERN.…”

Research involving event-related brain potentials has revealed that anxiety is associated with enhanced error monitoring, as reflected in increased amplitude of the error-related negativity (ERN). The nature of the relationship between anxiety and error monitoring is unclear, however. Through meta-analysis and a critical review of the literature, we argue that anxious apprehension/worry is the dimension of anxiety most closely associated with error monitoring. Although, overall, anxiety demonstrated a robust, “small-to-medium” relationship with enhanced ERN (r = −0.25), studies employing measures of anxious apprehension show a threefold greater effect size estimate (r = −0.35) than those utilizing other measures of anxiety (r = −0.09). Our conceptual framework helps explain this more specific relationship between anxiety and enhanced ERN and delineates the unique roles of worry, conflict processing, and modes of cognitive control. Collectively, our analysis suggests that enhanced ERN in anxiety results from the interplay of a decrease in processes supporting active goal maintenance and a compensatory increase in processes dedicated to transient reactivation of task goals on an as-needed basis when salient events (i.e., errors) occur.

“…The hypothesis that perceptual organization involves a central resource led us to predict Goodness effects on response time in same-different experiments (Berti, Geissler, Lachmann, & Mecklinger, 2000;Lachmann & Geissler, 2002;Lachmann & van Leeuwen, 2004, 2005a. Two stimuli were presented in sequence so that the response was made in absence of the first one and in the presence of the second one.…”

We adopted the Psychological Refractoriness Paradigm to study whether perceptual Goodness affects the load of central processing resources. In three dual-task experiments, 2-Alternative Forced Choice auditory classification was followed by a same-different task in which Garner's classical five-dot patterns were presented. Goodness of these patterns and stimulus-onset asynchrony (SOA) between the first and second task were varied between trials. These factors had additive effects on response latencies and accuracy, indicating that pattern Goodness determines central processing load in performing the same-different task. In a fourth experiment, same-different judgment with Garner patterns was the single task. SOA between the first and second pattern was varied. Over-additive effects of Goodness with decreasing SOA were obtained, indicating sharing of central resources between consolidation of the first Garner pattern and performing the same-different task. Whereas, the resources needed for the latter, again, depend on Goodness, those needed for consolidation are independent of it.
