Flexible behavior in humans often requires that rapid choices be made between conflicting action plans. Although much attention has focused on prefrontal regions, little is understood about the contribution of parietal cortex under situations of response conflict. Here we show that right parietal damage associated with spatial neglect leads to paradoxical facilitation (speeding) of rightward mo...

OBJECTIVE To examine factors that influence emotional adjustment, adherence to diabetic care, and glycemic control in Hong Kong youths with insulin-dependent diabetes mellitus (IDDM). METHODS Seventy youths, their mothers, and matched controls provided information on health beliefs, authoritarian parenting style, parent-child conflict, emotional adjustment, and adherence to medical regimen. G...

The error likelihood computational model of anterior cingulate cortex (ACC) (Brown, J.W., Braver, T.S., 2005. Learned predictions of error likelihood in the anterior cingulate cortex. Science 307: 1118-1121) has successfully predicted error likelihood effects, risk prediction effects, and how individual differences in conflict and error likelihood effects vary with trait differences in risk ave...

Real time group editors allow two or more users at different locations to work on a shared document at the same time. In a mobile network environment with nondeterministic communication latency, a replicated architecture is usually adopted for the storage of the shared document in order to provide high responsiveness. A conflict occurs when two or more users have different intentions for editin...

Conflict in information processing evokes trial-by-trial behavioral modulations. Influential models suggest that adaptive tuning of executive control, mediated by mid-dorsal lateral prefrontal cortex (mdlPFC) and anterior cingulate cortex (ACC), underlies these modulations. However, mdlPFC and ACC are parts of distributed brain networks including orbitofrontal cortex (OFC), posterior cingulate ...

background: as part of the process of developing a decision aid for carpal tunnel syndrome (cts) according to the ottawa decision support framework, we were interested in the level of ‘decisional conflict’ of hand surgeons and patients with cts. this study addresses the null hypothesis that there is no difference between surgeon and patient decisional conflict with respect to test and treatment...

This paper models the US-China trade conflict and attempts to analyze (optimal) strategic choices. In contrast existing literature on topic, we employ expected utility theory examine mathematically. both perfect information incomplete games, show that net gains diminish as of winning increases because costs incurred during struggle. We find best response function exists for China but not US con...

When an object is described as changing state during an event, do the representations of those states compete? The distinct states they represent cannot coexist at any one moment in time, yet each representation must be retrievable at the cost of suppressing the other possible object states. We used functional magnetic resonance imaging of human participants to test whether such competition doe...

Among vertebrates, winning a fight enhances the probability of future victories and vice versa and the role of post-conflict testosterone in mediating this 'winner effect' is widely accepted. In a series of staged fights of Japanese quail (Coturnix japonica) we tested both opponents' pre-fight and post-conflict testosterone, behavior and dominance status after returning to their social groups. ...
