Brain potentials in affective picture processing: covariation with autonomic arousal and affective report
The results suggest that the late positive wave indicates a selective processing of emotional stimuli, reflecting the activation of motivational systems in the brain. Expand
Affective picture processing: the late positive potential is modulated by motivational relevance.
The data support the view that late positivity to affective pictures is modulated both by their intrinsic motivational significance and the evaluative context of picture presentation. Expand
The facilitated processing of threatening faces: an ERP analysis.
Assessing early perceptual stimulusprocessing, threatening faces elicited an early posterior negativity compared with nonthreatening neutral or friendly expressions, and at later stages of stimulus processing, facial threat also elicited augmented late positive potentials relative to the other facial expressions, indicating the more elaborate perceptual analysis of these stimuli.

Emotion and attention: event-related brain potential studies.
It is concluded that ERP measures are useful to assess the emotion-attention interface at the level of distinct processing stages in response to stimulus novelty, emotional prime pictures, learned stimulus significance, and in the context of explicit attention tasks. Expand
Selective Visual Attention to Emotion
Emotion potentiated attention effects specifically during later stages of processing, suggesting to specify the interaction of attention and emotion in distinct processing stages. Expand
The selective processing of briefly presented affective pictures: an ERP analysis.
Data suggest that a quick glimpse of emotionally relevant stimuli appears sufficient to tune the brain for selective perceptual processing when pictures are presented only briefly. Expand
Brain processes in emotional perception: Motivated attention
Brain potentials and blink reflexes were recorded while participants viewed emotional pictures organised into content categories that varied in motivational significance. Event‐related potentials atExpand
Emotional Facilitation of Sensory Processing in the Visual Cortex
The hypothesis that sensory encoding of affective stimuli is facilitated implicitly by natural selective attention is supported, suggesting that the affect system not only modulates motor output, but already operates at an early level of sensory encoding. Expand
Attention and emotion: an ERP analysis of facilitated emotional stimulus processing
These data demonstrate the selective encoding of emotional stimuli while top-down attentional control was directed towards non-emotional target stimuli. Expand
Fear acquisition requires awareness in trace but not delay conditioning.
The present results suggest a more implicit learning process in delay fear conditioning, whereas the explicit acquisition of contingency awareness might be a prerequisite for trace fear conditioning. Expand
