چکیده

106 Cognitive Neuroscience Society replicate the Þ nding that high-frequency words can elicit an N250 priming effect using this paradigm, and further show that the presence and size of this effect is dependent upon the order of stimulus presentation. Both high-frequency and low-frequency N250 priming effects were larger when the words were presented in the Þ rst block. High-frequency words only elicited a signiÞ cant priming effect from 200-300ms when they preceded the low-frequency block. These Þ ndings suggest that the effects of word frequency on N250 masked priming effects are highly sensitive to experimental context. Both highand low-frequency words are inß uenced by presentation order and N250 priming effects may be especially sensitive to presentation parameters when participants read extremely high-frequency words.

Hemispheric asymmetry in event knowledge activation during incremental language comprehension: A visual half-field ERP study.

During incremental language comprehension, the brain activates knowledge of described events, including knowledge elements that constitute semantic anomalies in their linguistic context. The present study investigates hemispheric asymmetries in this process, with the aim of advancing our understanding of the neural basis and functional properties of event knowledge activation during incremental...

Event-Related Potentials of Bottom-Up and Top-Down Processing of Emotional Faces

Introduction: Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present st...

Native-like Event-related Potentials in Processing the Second Language Syntax: Late Bilinguals

Background: The P600 brain wave reflects syntactic processes in response to different first language (L1) syntactic violations, syntactic repair, structural reanalysis, and specific semantic components. Unlike semantic processing, aspects of the second language (L2) syntactic processing differ from the L1, particularly at lower levels of proficiency. At higher L2 proficiency, syntactic violatio...

Response inhibition is modulated by functional cerebral asymmetries for facial expression perception

The efficacy of executive functions is critically modulated by information processing in earlier cognitive stages. For example, initial processing of verbal stimuli in the language-dominant left-hemisphere leads to more efficient response inhibition than initial processing of verbal stimuli in the non-dominant right hemisphere. However, it is unclear whether this organizational principle is spe...

Behavioral and physiological findings of gender differences in global-local visual processing.

Hemispheric asymmetries in global-local visual processing are well-established, as are gender differences in cognition. Although hemispheric asymmetry presumably underlies gender differences in cognition, the literature on gender differences in global-local processing is sparse. We employed event related brain potential (ERP) recordings during performance of a global-local reaction time task to...
