The electrophysiological correlates of insight and non-insight problems solving were studied using eventrelated potentials (ERPs). Participants were given some time to guess Chinese logogriphs and then presented with an answer to judge whether it matched the logogriph. Results showed that the insight trials elicited a more negative ERP deflection (N300-500) than did the non-insight trials in mo...

Many clinical, behavioural and brain imaging studies have suggested that language functions are less asymmetrical in women than in men. Sommer and colleagues challenge this view in a recent review on the outcome of 24 functional brain imaging studies (PET, functional MRI or functional transcranial Doppler ultrasound) that looked at possible sex differences in language lateralization. A vote cou...

New evidence is accumulating for a deficit in binding visual-orthographic information with the corresponding phonological code in developmental dyslexia. Here, we identify the mechanisms underpinning this deficit using event-related brain potentials (ERPs) in dyslexic and control adult readers performing a letter-matching task. In each trial, a printed letter was presented synchronously with an...

Event-related brain potentials (ERPs) were used to investigate the visual processing of actions belonging to the typical human repertoire. Two hundred and sixty coloured pictures representing persons differing in number, age and gender, engaged in simple actions, were presented to 23 right-handed students. Perception of meaningful actions (e.g., young woman trying shoes in shop) was contrasted ...

The face-sensitive evoked N170 component of the event related potential (ERP) is reduced if another face is presented before when compared to the previous presentation of a low-level control stimulus (phase-scrambled face). This effect is thought to reflect category-specific adaptation processes. Similarly, presenting two faces concurrently also reduces the N170, suggesting that stimuli compete...

Endogenous potentials are evoked responses that occur independent of the stimulus evoking them. They are related to different aspects of information processing. Two types of event related potentials (ERPs) are recorded, the P300 wave and contingent negative variation (CNV). The P300 wave is the most frequently studied factor in various clinical diseases and also for neurological research. Diffe...

Given the current focus on anticipation in perception, action and cognition, including language processing, there is a need for a method to tap into predictive processing in situations in which cue and feedback stimuli are not explicitly marked as such. To this aim, event related potentials (ERPs) were obtained while participants viewed alphabetic letter sequences ("A", "B", "C", "D", "E", …), ...
