event-related brain potentials during picture naming, using early and late acquired words
background naming is a simple and basic skill of the language which involves semantic, lexical, and phonological levels. there are many different factors affecting the speed and convenience of naming. one of these factors is the word age of acquisition (aoa) and since language processing occurs at an extremely fast rate, psycholinguistics needs a method that has very good temporal resolution. t...
متن کاملLearning effects on event-related brain potentials.
This study investigates whether learning can manifest itself in EEG changes without explicit awareness of the acquired knowledge and without any motor requirement (to rule out acquisition of motor skills). Subjects passively heard particular stimulus combinations interspersed with random combinations. Immediately after this, stimulus combinations were presented which contained violations of the...
متن کاملEvent-related brain potentials dissociate visual working memory processes under categorial and identical comparison conditions.
Event-related potentials (ERPs) have been successfully employed to examine the functional and neuronal characteristics of working memory processes. In the present study, we examined the ERP waveforms in a delayed matching task to examine the cognitive processes underlying category and identity comparison and the effects of stimulus complexity. Subjects had to decide whether two visual stimuli a...
متن کاملEvent-related potentials dissociate perceptual from response-related age effects in visual search.
Attentional decline plays a major role in cognitive changes with aging. However, which specific aspects of attention contribute to this decline is as yet little understood. To identify the contributions of various potential sources of age decrements in visual search, we combined response time measures with lateralized event-related potentials of younger and older adults performing a compound-se...
متن کاملEvent-Related Potentials Dissociate Effects of Salience and Space in Biased Competition for Visual Representation
BACKGROUND Selective visual attention is the process by which the visual system enhances behaviorally relevant stimuli and filters out others. Visual attention is thought to operate through a cortical mechanism known as biased competition. Representations of stimuli within cortical visual areas compete such that they mutually suppress each others' neural response. Competition increases with sti...
