We investigated the effect of familiarity on people's perception of facial likeness by asking participants to choose which of two mirror-symmetric chimeric images (made from the left or right half of a photograph of a face) looked more like an original image. In separate trials the participants made this judgment for their own face and for the face of a(More)
We investigated hemispheric asymmetries in face processing using a task in which participants judged the likeness of chimeric faces to their own face and to the face of a close friend based on their memory for those faces. When asked to choose which of two mirror-symmetric images (one made from the left half and one from the right half of a photograph of(More)
— This paper describes two experimental testbeds which focus on real time verification and validation of semi-autonomous cooperative control. RoboFlag is an experimental and real time simulation of a capture the flag game using robots. The SeaScan is a long endurance UAV designed for military and commercial applications. For each testbed, details of(More)
This project outlines the strategy adopted for establishing two kinds of communications; one for wireless communication between a mobile Robot and a remote Base Station, another for serial communication between a remote Base Station and a GUI Application, PC. TekBot is a low cost mobile Robot built by Oregon State University which in its current version(More)
A new way to perform space missions utilizes the concept of clusters of satellites that cooperate to perform the function of a larger, single satellite. Each smaller satellite communicates with the others and shares the processing, communications, and payload or mission functions. The required functionality is thus spread across the satellites in the(More)
It is well documented that the majority of adults, children and families in need of evidence-based behavioral health interventions i do not receive them [1, 2] and that few robust empirically supported methods for implementing evidence-based practices (EBPs) exist. The Society for Implementation Research Collaboration (SIRC) represents a burgeoning effort(More)
Introduction Although recent advances have improved understanding of what it takes to successfully implement and sustain evidence-based practices (EBPs) in communities and to transform health care systems, there remains a dearth of knowledge regarding methods for measuring and subsequently evaluating these efforts. Recognizing the complexity of the process,(More)
In this thesis, we investigate human decision making dynamics in a series of simple perceptual decision making tasks. The level of caution with which a human subject responds to stimuli is of central interest, since it influences the speed and accuracy of responses. We study the role of caution parameters in models of cognitive control processes. We first(More)
