The Effects of Age and Task on Visual Emotion Processing
… facial expressions elicit enhanced P1 and N170 components of visually-evoked event-related potentials (ERP) over posterior scalp regions associated with vision. The current study examined the extent to which angry and happy facial expressions evoked differential patterns of P1 and N170 …

The Influence of Media Violence on the Neural Correlates of Empathic Emotional Response
… control in these populations, specifically the N170 and N200 ERP components were examined while participants completed a stop-signal task using emotional faces. At baseline, gamers and nongamers performed equally well at a gender discrimination task and at inhibiting behavior, but gamers had …

DO STRATEGIC PRIMING PROCESSES DIFFER FOR CATEGORY VS. ASSOCIATIVE PRIMING? AN EVENT-RELATED POTENTIALS STUDY OF PROACTIVE EXPECTANCY STRATEGIES.
… mediated by facilitation and would influence the N170 and that the categorical effects would be indexed by the N300 for inhibitory effects and the N400 for facilitatory effects. Inhibition was not seen for unrelated targets in the categorical condition. The fillers in the categorical condition …

Electrophysiological investigations of the timing of face processing
… the N250 decreased. In contrast, the P100, the N170 and the early P2 components were not affected by face identity strength. These results suggest that face recognition occurs after 200 ms, but not earlier. Finally, because faces are often associated with social information, we investigated in …

Neurophysiologische Korrelate der Verarbeitung von Gesichtern und emotionalen Gesichtsausdrücken bei Gesunden und Patienten mit schizophrenen Erkrankungen
… widerspiegelt (Gesichterpeak, N170). Die N170 konnte mit dem Quellenlokalisationsprogramm LORETA unter anderem im Gyrus Fusiformis, der entsprechenden Hirnregion für die Gesichtsverarbeitung, lokalisiert werden. Für die Dekodierung emotionaler Gesichtsausdrücke konnten keine …

ERP and Theta Activity Associated with Facial Emotion Memory
… P1 amplitudes at occipital electrode sites and N170 amplitudes at parietal sites differed by emotional expression. Increased P1 at occipital sites was the best predictor of correct matching of positive emotions whereas N170 amplitudes at parietal sites predicted correct identification of …

The Role of Sleep and Hormones in Processing of Emotional Information
… in men, and estradiol and progesterone in women. N170 and LPP event-related potentials were recorded during emotional face categorization and image categorization tasks respectively. Sleep-restricted participants were less accurate identifying sad facial expressions, and displayed a larger N170 …

Event-related potential correlates of face-emotion processing impairments in bipolar disorder
… in the BD group only, and overall attenuated N170 amplitudes. The second analysis revealed overall prolonged peak latencies of the fronto-central P80 and vertex positive potentials in BD patients. Delayed response inhibition of emotional stimuli in BD was identified in the third analysis. In …

The Role of Cardiac Vagal Tone in Prediction of Individual Differences in Attention and Emotion Processing After Sleep Restriction
… as happy, sad, fearful, angry, or neutral; N170 event-related potentials to face stimuli were examined. Affective pictures were presented in a second task, and were identified as negative, neutral or positive by participants; the LPP event-related potential, a measure of sustained attention …

Individual Differences in Emotional Awareness and the Lateralized Processing of Emotion
… Most notably, only female HAs exhibited: (1) an N170 that was larger over the posterior RH than left hemisphere (LH), suggesting higher autonomic arousal, and (2) a lack of differentiation by N400 of facial expressions over the posterior RH when interhemispheric communication was required. These …

Facial Processing and Social Motivation In Psychopathy: An Event-Related Potential Study
… relationships. In addition, the ‘face sensitive’ N170 and ‘emotion sensitive’ late positive potential (LPP) ERP components were examined in response to passive-viewing tasks focused on the processing of faces, as well as social and non-social, emotionally arousing stimuli. Results showed that …

Electrophysiological indices of the violence inhibition mechanism and their associations with physical agression, callous-unemotional traits, and dietary omega-3
… indices of structural/featural face processing (N170, P200), aggressive traits, specifically physical aggression, were associated with electrophysiological indices of distressinduced motor extinction (stop-N200, stop-P300). Furthermore, in light of a growing literature suggesting a benefit of …

Visual Object-Category Processing with and without Awareness
… discrimination by the brain (the face-specific N170 ERP component and the longer-latency face-specific negativity) were tracked across conditions of visual awareness as manipulated by multiple presentation paradigms (sandwich masking, object-substitution masking, the attentional blink, and …

Investigating cortical arousal and cognition in schizophrenia and methamphetamine-induced psychotic disorder: an electroencephalography and cytokine study
… performance and relative frequency and ERP (N170, P300) during the STROOP task, a measure of working memory and executive function; (5) the associations of (neuro) inflammatory markers with relative frequency and the P300 ERP waveform. Methods: 104 South African individuals, between the ages …

The electrophysiological correlates of processing expression intensities along emotion trajectories
… reflected by graded modulation of the N170 based on expression intensity. Additionally, EPN amplitudes were more graded for angry expressions than happy expression intensities, suggesting that angry intensities were processed in more depth than happy ones. EPN amplitudes for each …

High functioning autism and common coexisting conditions: An EEG investigation
… differences in the latency or amplitude of the N170. There were, however, differences in the amplitude of the P250. Those with ASD and ADHD showed a differential profile in response to sad and neutral stimuli on the P250 from one another. Those with ASD had larger amplitudes toward mouth stimuli …

Executive control: an electrophysiological investigation of control processes
… stimulus feature. This was done by measuring N170 amplitude - an ERP component proposed to index face processing - when a face stimulus served as the relevant and irrelevant stimulus dimension. Again, conflict adaptation effects were evident in overt behaviour, with this effect being driven by …
