Survivors of severe traumatic brain injury (TBI) often demonstrate impairments in the cognitive control functions of detecting response conflict and signaling for recruitment of cognitive resources to appropriately adjust performance. These cognitive control functions can be measured using conflict adaptation effects, wherein manifestations of conflict detection and processing are reduced follo...

This paper investigates the automatic recognition of conflict escalations during spontaneous conversations. In our previous work, we studied if the level of conflict in a segment of conversation can be automatically inferred by means of prosodic and conversational features. This work investigates the possibility of automatically recognizing if the conflict is increasing, i.e., escalating, or no...

This study compared pilot situation awareness across three traffic management concepts. The Concepts varied in terms of the allocation of traffic avoidance responsibility between the pilot on the flight deck, the air traffic controllers, and a conflict resolution automation system. In Concept 1, the flight deck was equipped with conflict resolution tools that enable them to fully handle the res...

A Study of Conflict Detection in Software Transactional Memory Daniel Lupei Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2009 Transactional Memory (TM) has been proposed as a simpler parallel programming model compared to the traditional locking model. However, uptake from the programming community has been slow, primarily because pe...

A recent theoretical account delineated the role of the anterior cingulate cortex (ACC) in cognitive control as the detection of conflict between competing information streams. Using functional magnetic resonance imaging, we examined the activity of this brain structure during different forms and degrees of conflict between the word and the color dimensions of Stroop stimuli. Overall, our resul...

Conflict detection and resolution (CD&R) systems predict loss of separation between aircraft and propose conflict avoidance maneuvers for the aircraft involved in the conflict. Given a pair of aircraft in conflict, the ownship and the intruder, the resolution system diverts the ownship from its original trajectory. In this paper, we introduce the concept of recovery course. A recovery course re...

The study of alternative combination rules in DS theory when evidence is in conflict has emerged again recently as an interesting topic, especially in data/information fusion applications. These studies have mainly focused on investigating which alternative would be appropriate for which conflicting situation, under the assumption that a conflict is identified. The issue of detection (or identi...

The anterior cingulate cortex (ACC) has been suggested as a monitoring center that is responsible for online detection of response conflicts. In this view, the conflict signal detected by the ACC is transmitted to other brain regions, such as the dorsal part of the lateral prefrontal cortex (lPFC), to increase the level of cognitive control. In this functional MRI (fMRI) study, we examined the ...
