By promoting the use of abstract stimulus information for memory retrieval, we were thus able to show that hemispheric asymmetries in accessing abstract or specific memory representations can modulate ERP correlates of familiarity as well as recollection processes.
In this study, we investigated how predictions about timing of pitch perturbations in voice auditory feedback would modulate ERP and behavioral responses during vocal production.
In addition, AoA modulated ERP activity in centroparietal electrode sites, with early-acquired words eliciting a larger positivity (P300) than late-acquired words.
Semantic violations (factor Correctness) modulated ERP amplitudes between 350 and 500 ms as main effect, all Fs(1,31)>10.3, ps<.01, and between 350 and 450 ms in interaction with Electrode, Fs(26,806) = 3.0 and 2.8, ps<.05, εs = .160 and.161 (cf. Table 2).
Importantly, voluntary modulations of parietal ERP amplitudes were specific to crime probes, with no significant modulations of ERPs to targets or control items across phases in either experiment.
The event-related potential (ERP) technique has been used to assess the mechanisms of audio-visual speech perception in adults, with visual cues reliably modulating auditory ERP responses to speech.
Moreover, early and late ERPs to emotional processing are modulated by psychiatric medication [ 87].
Visual inspection indicated a considerably smaller ERN amplitude in the smile condition, whereas the ERPs to the correct stimuli were not modulated by facial expression.
Figure 5 shows ERPs to objects for each group separately.
These analyses revealed that, at the occipital sites, ERPs to happy deviants differed from ERPs to standards earlier than ERPs to fearful deviants differed from ERPs to standards.
