Evidence in the literature for the proposed relationship between the error-related negativity (ERN) and error correction is rather limited and inconsistent. We investigated corrective behavior and the ERN in two groups of participants who performed a flanker task. The correction-instructed group was asked to immediately correct all encountered errors. The noninstructed group was unaware that co...

Aggressive behavior in girls has received far less attention than similar problems in boys. This study examined self-representation, and others' representation of self, as predictors of relational aggression, overt aggression, and assaultive behavior in 32 girls and 52 boys, 10 to 17 years of age, referred for assessment due to significant aggressive and delinquent behavior problems. As predict...

Bare numerals (e.g. two) seem to be ambiguous between two readings: the exactly and the at least reading. We present an ERP study that explores this issue. We show that the pattern of the ERPs elicited by critical nouns in sentences with unembedded bare numerals depends on the participant’s choice of the reading of the numeral. For those responders who consistently apply the exactly reading in ...

Change in maternal report of sibling negativity was investigated in 313 sibling dyads from 171 families taking part in a longitudinal, general population survey in the United Kingdom. The inclusion of multiple dyads per family allowed for the emergence of 3 novel elements for sibling research: an examination of within-family similarity on sibling relationship quality, modeling within-family sim...

Previous studies find that the feedback-related negativity in brain potentials is sensitive to the negative outcome of one's own performance. The feedback-related negativity is suggested to reflect the learning processes using feedback about the consequences of recent actions. Learning can also take place when one observes other people's actions and the associated outcomes. We recorded brain po...

Selecting between two candidates during a campaign is a crucial first step toward political involvement: an individual who does not select a preferred political candidate is unlikely to take political action. Can negative campaign ads help individuals make these electoral choices? Empirical evidence on this topic has been mixed. Some argue that negativity can increase the likelihood of choice. ...

Theories and empirical studies concerned with the action monitoring functions of the medial frontal cortex have generally assumed that numerous medial frontal negativities--such as the error-related negativity (ERN/Ne), N2, and the negativity elicited by error feedback and monetary losses--all reflect the activity of a common underlying neural generator. Several reports have asserted that the E...

A linguistic analysis shows differences in the way narcissistic and nonnarcissistic users communicate on Twitter. Because narcissism is marked by attention-seeking, and is related to negativity and perceived victimization, we hypothesized that narcissists would use more words about anger and negative emotions. Conversely, we further hypothesized that they would use fewer words about social inte...

BACKGROUND Many formulations of Thimerosal (49.55% mercury by weight)-containing Rho(D) immune globulins (TCRs) were routinely administered to Rh-negative mothers in the US prior to 2002. OBJECTIVES It was hypothesized: (1) if prenatal Rho(D)-immune globulin preparation exposure was a risk factor for neurodevelopmental disorders (NDs) then more children with NDs would have Rh-negative mothers...

In this study, 126 children were observed at 6 months, 12 months, and 2 years. During infancy, latencies to reach for novel objects were measured. At 2 years, positive and negative affect, and behavioral approach-inhibition to low- and high-intensity situations were coded, and mothers assessed behavior problems. Confirmatory factor analysis indicated a 3-dimension model of positivity, negativit...
