Follow the signal: models of attention, reason, and belief
Attention, reasoning, and belief are central to how we perceive, decide, and collaborate. Though inherently abstract-with no direct physical manifestation these phenomena leave behind observable signals in subtle traces in gaze, language, timing, and interaction. These traces vary across …

Modeling the control of visual attention in complex workspaces
Attentional behavior in complex visual workspaces is driven by the physical and temporal characteristics of the display, the goals and knowledge of the operator, and task demands. Accordingly, to develop effective displays, designers must understand how these factors interact to influence …

The Processing of Stimulus Attributes: Evidence for Dual-Task Integrality (Erp, P300, Time Sharing)
… which lead to dual-task decrements. Capacity models of attention which postulate a hypothetical resource structure underlying performance have been employed as predictive devices. These models predict that tasks which require different processing resources can be more successfully time shared …

Supporting Pilot Performance With an Integrated Flight Path Head -Up Display
… head-down, and pilots performed a series of simulated tasks in low and high visibility. The results indicate that while detection of events is generally enhanced by the HUD, tracking is influenced by the level of available visual detail when the HUD is used. When little visual detail is …

Highly Selective Attentional Modulation of Task-Appropriate Neural Populations in Primary Visual Cortex
A wide variety of different forms of attention have been described in the human and non-human literature, however the recently developed Input Gain Model of visual attention proposes that a simple neural mechanism, multiplicative gain, may be employed to explain much of the available data on visual …

The benefits of getting horizontal
The goal of much research in vision is to better understand the mechanisms of attention. This is often accomplished by using models of attention to predict how the placement of stimuli on a computer screen will affect task difficulty. However, recent research has shown there are asymmetries in …

Your Attention Please: Neural Networks, Individual Differences, and Clinical Implications of Attentional Control in the Human Brain
Our brains ability to direct our attention requires paradoxical processing. We must be able to focus and maintain our attention without allowing external stimuli to lure us off task. Yet, we must also be able to shift our attention flexibly to switch tasks in response to relevant cues. Unitary …

The Effect of improvisations and Observations on Standardized Patient Encounters, Subjective Workload and Stress
… feedback. This study investigated the effect of improvisations and multiple task performance on the ability to observe another's nonverbal (NV) behaviors and rate their communication skills. Subjective reports of mental workload and stress were also obtained. The first study involved …

Neural correlates of trait mindfulness
… need to identify the brain biological bases of mental health and mental illness. In this thesis, I focus on the brain bases of trait mindfulness, measured using self-report. Mindful individuals pay attention to the present moment and bring an attitude of acceptance and non-judgement to their …

Re-Examining the Stop-Signal Task to Test Competing Theories of AD/HD
<p>The current study tested two competing models of Attention-Deficit/Hyperactivity Disorder (AD/HD), the inhibition and state regulation theories, by conducting fine-grained analyses of the Stop-Signal Task and another putative measure of behavioral inhibition, the Gordon Continuous Performance …
