Feedback negativity is a negative component of the event-related brain potential observed 250-300 ms after feedback stimuli. The present study investigated the effects of value (correct or incorrect) and reward magnitude (no, small or large) on feedback negativity and P300. Feedback negativity was larger after incorrect feedback than after correct feedback, irrespective of reward magnitude. In ...

In order to advance our understanding of the etiology of individual differences in child maladjustment (i.e., conduct and emotional problems), we tested hypotheses about the statistical interactions between child temperament and two aspects of the family environment: maternal negativity and positivity, and household chaos (e.g., crowding, noise, lack of routines). Mothers (n = 149) reported on ...

OBJECTIVE The mismatch negativity, a negative component in the auditory event-related potential, is thought to index automatic processes involved in sensory or echoic memory. The authors' goal in this study was to examine the topography of auditory mismatch negativity in schizophrenia with a high-density, 64-channel recording montage. METHOD Mismatch negativity topography was evaluated in 23 ...

Negativity in election campaign matters. To what extent can the content of social media posts provide a reliable indicator candidates' negativity? We introduce and critically assess an automated classification procedure that we trained to annotate more than 16,000 tweets candidates competing 2018 Senate Midterms. The algorithm is able identify presence political attacks (both general, specifica...

Feedback indicating monetary loss elicits an apparent negative deflection in the event-related potential (ERP) that has been referred to as the feedback error-related negativity, medial frontal negativity, feedback-related negativity, and feedback negativity-all conceptualizations that suggest a negative ERP component that is greater for loss than gain. In the current paper, I review a programm...

Suppose we are given a differentiable path η̂. Is it possible to derive sub-minimal subsets? We show that every integral monodromy is rightJacobi and countably stochastic. This leaves open the question of uncountability. Unfortunately, we cannot assume that there exists an abelian unique topos.

Work in political communication has discussed the ongoing predominance of negative news, but has offered few convincing accounts for this focus. A growing body of literature shows that humans regularly pay more attention to negative information than to positive information, however. This article argues that we should view the nature of news content in part as a consequence of this asymmetry bia...

Inversion of U as the only abnormal electrocardiographic finding is here shown to be the first change to occur in certain cases of hypertension, coronary artery sclerosis, and other organic heart disease. It is also found in association with certain metabolic and electrolyte changes. Its recognition will enhance the value of the electrocardiogram in clinical diagnosis. T HE CLINICAL significanc...
