Priming reveals attentional modulation of human motion sensitivity

AbstractAlthough recent fMRI and single unit recording studies have shown that attention modulates neural activity in motion sensitive areas of extrastriate cortex, these approaches cannot reveal qualitative or quantitative effects of attention on perception of motion. To investigate this, we asked observers to select one of two orthogonal directions in a brief, transparent dot display (prime) and then measured their sensitivity to global directional motion in a second uni-directional dot display (probe) presented a short time later. When probe direction matched the attended prime direction, sensitivity was degraded. But, when probe direction matched the ignored prime direction, sensitivity was enhanced, even though both components were of equal physical strength. Sensitivity was unchanged for directions opposite to either previously seen direction. Neither sensory adaptation nor opponent direction mechanisms can account for these data. Rather, processes initiated by visual selection must underlie these dramatic changes in motion sensitivity

A Study of the Effectiveness of Water Resources Planning Groups A Final Report

Information and recommendations were developed pertaining to the organization of regional and river basin water planning studies, useful to river basin commissions and others responsible for such studies. The approach that was used included four basic components: (1) conceptualization of a planning model, based on an analysis of planning theory and organizational literature, (2) analysis and review of historical trends in water resources planned, (3) examination and comparative evaluation of 15 river basin planning studies, and (4) case studies of two planning efforts selected from the 15 examined in order to perform a more detailed analysis and to gain information about the informal aspects of the planning process that took place. In connection with the formulation of the planning model, a substantial amount of research effort was committed to the development of a computer simulation of decision-making in the planning or policy formulation process. This programmed simulation is designed to be a useful planning tool for gaining insights into the interrelationships among objectives, alternative courses of action, and political feasibility. A description of the simulation model and an analysis of tis application to the Willamette River Basin Comprehensive Study are presented
