Hedonic response is preserved in schizophrenia. However, it is unclear whether this is also true in individuals meeting criteria for “prodromal” psychosis, who are considered to be at symptomatic high risk for developing the disorder. In this study, we examined neurophysiological and self-reported response to emotional stimuli in UHR (n= 23) and healthy control (CN: n = 30) participants who pas...

Recollection is typically associated with high recognition confidence and accurate source memory. However, subjects sometimes make accurate source memory judgments even for items that are not confidently recognized, and it is not known whether these responses are based on recollection or some other memory process. In the current study, we measured event related potentials (ERPs) while subjects ...

Selective attention may be focused upon a region of interest within the visual surroundings, thereby improving the perceptual quality of stimuli at that location. It has been debated whether this spatially selective mechanism plays a role in the attentive selection of whole objects in a visual scene. The relationship between spatial and object-selective attention was investigated here through r...

The main objective of our study is to analyze the event related potential (ERP) of EEG brain signal from different emotional responses. An affective picture simulation was designed to find out neurophysiological characteristics of EEG brain signal. Event oriented EEG dynamics in ERP were analyzed statistically by using the one-way ANOVA method (p<0.01). Twenty one healthy college students were ...

The paper describes the three language-related event-related brain potentials (ERP) components: the N400 correlated with processes of semantic integration, the early mainly left accentuated anterior negativity correlated with initial structure building processes and the P600 reflecting processes of syntactic integration. These components are functionally specified with respect to normal compreh...

According to the Universal Writing System Constraint, all writing systems encode language, and thus reflect basic properties of the linguistic system they encode. According to a second universal, the Universal Phonological Principle, the activation of word pronunciations occurs for skilled readers across all writing systems. We review recent research that illustrates the implications of these t...

This study investigates brain potentials to derived word forms in Spanish. Two experiments were performed on derived nominals that differ in terms of their productivity and semantic properties but are otherwise similar, an acceptability judgment task and a reading experiment using event-related brain potentials (ERPs) in which correctly and incorrectly formed derived words were presented in sen...

Lexical decisions to high- and low-arousal negative words and to low-arousal neutral and positive words were examined in an event-related potentials (ERP) study. Reaction times to positive and high-arousal negative words were shorter than those to neutral (low-arousal) words, whereas those to low-arousal negative words were longer. A similar pattern was observed in an early time window of the E...

Explicit memory declines with age while implicit memory remains largely intact. These experiments extended behavioral findings by recording event-related potentials (ERPs) in young and elderly adults during repetition priming and recognition memory paradigms. Words and pronounceable nonwords repeated after 1 of 3 delays. Stimuli were categorized as either word-nonword or old-new. Repeated items...
