The negativity bias in affective picture processing depends on top-down and bottom-up motivational significance.
TLDR
Investigation of 2 factors that could influence the detection of a negativity bias in emotional picture processing: picture-presentation paradigm and specific picture content finds that emotional images elicited larger responses in the late positive potential (LPP) than did neutral images.
Positive emotion modulates cognitive control: an event-related potentials study.
TLDR
Overall, the results indicated that positive emotion could facilitate cognitive control processing, in line with the neuropsychological theory, according to which,positive emotion could modulate cognitive control mediated by increased dopamine levels in frontal brain areas.
Early Negativity Bias Occurring Prior to Experiencing of Emotion
The present study analyzed event-related potentials (ERPs) in different valence conditions to investigate whether negativity bias can occur prior to the experiencing of negative emotion. There were
Beyond good and evil: the time-course of neural activity elicited by specific picture content.
TLDR
Electrocortical evidence for a negativity bias in two early components, the N1 and the Early Posterior Negativity (EPN), is examined, revealing that unpleasant images did elicit a larger late positive potential (LPP) than pleasant pictures, and including exciting images in pleasant ERP averages disproportionately reduces the LPP.
Emotional modulation of the late positive potential (LPP) generalizes to Chinese individuals.

Attentional bias modulation by reappraisal in patients with generalized anxiety disorder: an event-related potential study
TLDR
It was found that in GAD patients only, the mean P200 amplitude after negative word presentation was much higher than after the presentation of neutral words, and this was significant in both the left and right regions.
Mindfulness Trait Predicts Neurophysiological Reactivity Associated with Negativity Bias: An ERP Study
TLDR
Results showed that increased mindfulness scores predicted increased valence ratings of negative stimuli (less negative), as well as increased P2 amplitudes at the frontocentral location for positive compared to negative stimuli, and a plausible mechanism of mindfulness in reducing negativity bias was discussed.

Emotion and Attention Interaction Studied through Event-Related Potentials
TLDR
The conjunction of temporal and spatial characteristics of P200post and P340post leads to the deduction that input processing-related attention associated with emotional visual stimulation involves an initial, rapid, and brief early attentional response oriented to rapid motor action, being more prominent towards negative stimulation.
The selective processing of briefly presented affective pictures: an ERP analysis.
TLDR
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.

Negative information tends to influence evaluations more strongly than comparably extreme positive information. To test whether this negativity bias operates at the evaluative categorization stage,

TLDR
Using a large emotional picture library, reliable affective psychophysiologies are shown, defined by the judged valence (appetitive/pleasant or aversive/unpleasant) and arousal of picture percepts.

Automatic vigilance: the attention-grabbing power of negative social information.
TLDR
To test whether attentional resources are automatically directed away from an attended task to undesirable stimuli, Ss named the colors in which desirable and undesirable traits appeared, and color-naming latencies were consistently longer for undesirable traits but did not differ within the desirable and desirable categories.
